wordpress class WP_Date_Query {} class WP\_Date\_Query {}
========================
Class for generating SQL clauses that filter a primary query according to date.
[WP\_Date\_Query](wp_date_query) is a helper that allows primary query classes, such as [WP\_Query](wp_query), to filter their results by date columns, by generating `WHERE` subclauses to be attached to the primary SQL query string.
Attempting to filter by an invalid date value (eg month=13) will generate SQL that will return no results. In these cases, a [\_doing\_it\_wrong()](../functions/_doing_it_wrong) error notice is also thrown.
See [WP\_Date\_Query::validate\_date\_values()](wp_date_query/validate_date_values).
* [\_\_construct](wp_date_query/__construct) — Constructor.
* [build\_mysql\_datetime](wp_date_query/build_mysql_datetime) — Builds a MySQL format date/time based on some query parameters.
* [build\_time\_query](wp_date_query/build_time_query) — Builds a query string for comparing time values (hour, minute, second).
* [build\_value](wp_date_query/build_value) — Builds and validates a value string based on the comparison operator.
* [get\_compare](wp_date_query/get_compare) — Determines and validates what comparison operator to use.
* [get\_sql](wp_date_query/get_sql) — Generates WHERE clause to be appended to a main query.
* [get\_sql\_clauses](wp_date_query/get_sql_clauses) — Generates SQL clauses to be appended to a main query.
* [get\_sql\_for\_clause](wp_date_query/get_sql_for_clause) — Turns a first-order date query into SQL for a WHERE clause.
* [get\_sql\_for\_query](wp_date_query/get_sql_for_query) — Generates SQL clauses for a single query array.
* [get\_sql\_for\_subquery](wp_date_query/get_sql_for_subquery) — Turns a single date clause into pieces for a WHERE clause.
* [is\_first\_order\_clause](wp_date_query/is_first_order_clause) — Determines whether this is a first-order clause.
* [sanitize\_query](wp_date_query/sanitize_query) — Recursive-friendly query sanitizer.
* [sanitize\_relation](wp_date_query/sanitize_relation) — Sanitizes a 'relation' operator.
* [validate\_column](wp_date_query/validate_column) — Validates a column name parameter.
* [validate\_date\_values](wp_date_query/validate_date_values) — Validates the given date\_query values and triggers errors if something is not valid.

wordpress class WP_REST_Widget_Types_Controller {} class WP\_REST\_Widget\_Types\_Controller {}
============================================
Core class to access widget types via the REST API.
* [WP\_REST\_Controller](wp_rest_controller)
* [\_\_construct](wp_rest_widget_types_controller/__construct) — Constructor.
* [check\_read\_permission](wp_rest_widget_types_controller/check_read_permission) — Checks whether the user can read widget types.
* [encode\_form\_data](wp_rest_widget_types_controller/encode_form_data) — An RPC-style endpoint which can be used by clients to turn user input in a widget admin form into an encoded instance object.
* [get\_collection\_params](wp_rest_widget_types_controller/get_collection_params) — Retrieves the query params for collections.
* [get\_item](wp_rest_widget_types_controller/get_item) — Retrieves a single widget type from the collection.
* [get\_item\_permissions\_check](wp_rest_widget_types_controller/get_item_permissions_check) — Checks if a given request has access to read a widget type.
* [get\_item\_schema](wp_rest_widget_types_controller/get_item_schema) — Retrieves the widget type's schema, conforming to JSON Schema.
* [get\_items](wp_rest_widget_types_controller/get_items) — Retrieves the list of all widget types.
* [get\_items\_permissions\_check](wp_rest_widget_types_controller/get_items_permissions_check) — Checks whether a given request has permission to read widget types.

wordpress class WP_Network {} class WP\_Network {}
====================
Core class used for interacting with a multisite network.
This class is used during load to populate the `$current_site` global and setup the current network.
This class is most useful in WordPress multi-network installations where the ability to interact with any network of sites is required.
* [\_\_construct](wp_network/__construct) — Creates a new WP\_Network object.
* [\_\_get](wp_network/__get) — Getter.
* [\_\_isset](wp_network/__isset) — Isset-er.
* [\_\_set](wp_network/__set) — Setter.
* [\_set\_cookie\_domain](wp_network/_set_cookie_domain) — Sets the cookie domain based on the network domain if one has not been populated.
* [\_set\_site\_name](wp_network/_set_site_name) — Sets the site name assigned to the network if one has not been populated.
* [get\_by\_path](wp_network/get_by_path) — Retrieves the closest matching network for a domain and path.
* [get\_instance](wp_network/get_instance) — Retrieves a network from the database by its ID.
* [get\_main\_site\_id](wp_network/get_main_site_id) — Returns the main site ID for the network.

wordpress class WP_HTTP_Proxy {} class WP\_HTTP\_Proxy {}
========================
Core class used to implement HTTP API proxy support.
There are caveats to proxy support. It requires that defines be made in the wp-config.php file to enable proxy support. There are also a few filters that plugins can hook into for some of the constants.
Please note that only BASIC authentication is supported by most transports.
cURL MAY support more methods (such as NTLM authentication) depending on your environment.
The constants are as follows:
1. WP\_PROXY\_HOST – Enable proxy support and host for connecting.
2. WP\_PROXY\_PORT – Proxy port for connection. No default, must be defined.
3. WP\_PROXY\_USERNAME – Proxy username, if it requires authentication.
4. WP\_PROXY\_PASSWORD – Proxy password, if it requires authentication.
5. WP\_PROXY\_BYPASS\_HOSTS – Will prevent the hosts in this list from going through the proxy.
You do not need to have localhost and the site host in this list, because they will not be passed through the proxy. The list should be presented in a comma separated list, wildcards using \* are supported. Example: \*.wordpress.org
An example can be as seen below.
```
define('WP_PROXY_HOST', '192.168.84.101');
define('WP_PROXY_PORT', '8080');
define('WP_PROXY_BYPASS_HOSTS', 'localhost, www.example.com, *.wordpress.org');
```
* [authentication](wp_http_proxy/authentication) — Retrieve authentication string for proxy authentication.
* [authentication\_header](wp_http_proxy/authentication_header) — Retrieve header string for proxy authentication.
* [host](wp_http_proxy/host) — Retrieve the host for the proxy server.
* [is\_enabled](wp_http_proxy/is_enabled) — Whether proxy connection should be used.
* [password](wp_http_proxy/password) — Retrieve the password for proxy authentication.
* [port](wp_http_proxy/port) — Retrieve the port for the proxy server.
* [send\_through\_proxy](wp_http_proxy/send_through_proxy) — Determines whether the request should be sent through a proxy.
* [use\_authentication](wp_http_proxy/use_authentication) — Whether authentication should be used.
* [username](wp_http_proxy/username) — Retrieve the username for proxy authentication.

wordpress class WP_Screen {} class WP\_Screen {}
===================
Core class used to implement an admin screen API.
This is a concrete class that is instantiated in the WordPress $screen global. It is primarily used to create and customize WordPress admin screens (as of WordPress 3.3).
Note: Please refer source code for the complete list of properties.
The following properties are built into the [WP\_Screen](wp_screen) class.
$action Any action associated with the screen. 'add' for \*-add.php and \*-new.php screens. Empty otherwise. $base The base type of the screen. This is typically the same as $id but with any post types and taxonomies stripped. For example, for an $id of 'edit-post' the base is 'edit'. $id The unique ID of the screen. $is\_network Whether the screen is in the network admin. $is\_user Whether the screen is in the user admin. $parent\_base The base menu parent. This is derived from $parent\_file by removing the query string and any .php extension. $parent\_file values of 'edit.php?post\_type=page' and 'edit.php?post\_type=post' have a $parent\_base of 'edit'. $parent\_file The $parent\_file for the screen per the admin menu system. Some $parent\_file values are 'edit.php?post\_type=page', 'edit.php', and 'options-general.php'. $post\_type The post type associated with the screen, if any. The 'edit.php?post\_type=page' screen has a post type of 'page'. The 'edit-tags.php?taxonomy=$taxonomy&post\_type=page' screen has a post type of 'page'. $taxonomy The taxonomy associated with the screen, if any. The 'edit-tags.php?taxonomy=category' screen has a taxonomy of 'category'. The following properties are built into the [WP\_Screen](wp_screen) class.
$\_help\_tabs Private. The help tab data associated with the screen, if any. $\_help\_sidebar Private. The help sidebar data associated with screen, if any. $\_old\_compat\_help Private. Stores old string-based help. $\_options Private. The screen options associated with screen, if any. $\_registry Private. The screen object registry. $\_show\_screen\_options Private.

| --- | --- |
| [6.1.0](https://developer.wordpress.org/reference/since/6.1.0/) | Introduced. |
wordpress class WP_User_Query {} class WP\_User\_Query {}
========================
Core class used for querying users.
* [WP\_User\_Query::prepare\_query()](wp_user_query/prepare_query): for information on accepted arguments.
This class allows querying WordPress database tables ‘wp\_users‘ and ‘wp\_usermeta‘.
```
<?php
$args = array(
.
.
.
);
// The Query
$user_query = new WP_User_Query( $args );
// User Loop
if ( ! empty( $user_query->get_results() ) ) {
foreach ( $user_query->get_results() as $user ) {
echo '<p>' . $user->display_name . '</p>';
}
} else {
echo 'No users found.';
}
?>
```
Show users associated with certain role.
* **role** (*string / array*) – use [User Role](https://wordpress.org/support/article/roles-and-capabilities/ "Roles and Capabilities"). An array or a comma-separated list of role names that users must match to be included in results. Note that this is an inclusive list: users must match \*each\* role. Default empty.
* **role\_\_in** (*array*) – An array of role names. Matched users must have at least one of these roles. Default empty array. (since [Version 4.4](https://codex.wordpress.org/Version_4.4 "Version 4.4")).
* **role\_\_not\_in** (*array*) – An array of role names to exclude. Users matching one or more of these roles will not be included in results. Default empty array. (since [Version 4.4](https://codex.wordpress.org/Version_4.4 "Version 4.4")).
**Display Administrator role users**
```
$user_query = new WP_User_Query( array( 'role' => 'Administrator' ) );
```
**Display Subscriber role users**
```
$user_query = new WP_User_Query( array( 'role' => 'Subscriber' ) );
```
**Display all users except Subscriber role users**
```
$user_query = new WP_User_Query( array( 'role__not_in' => 'Subscriber' ) );
```
Show specific users.
* **include** (*array*) – List of users to be included.
* **exclude** (*array*) – List of users to be excluded.
**Display specific users list**
```
$user_query = new WP_User_Query( array( 'include' => array( 1, 2, 3 ) ) );
```
**Display all users except a specific list of users**
```
$user_query = new WP_User_Query( array( 'exclude' => array( 4, 5, 6 ) ) );
```
Show users associated with certain blog on the network.
* **blog\_id** (*int*) – The blog id on a multisite environment. Defaults to the current blog id.
**Display users from blog 33**
```
$user_query = new WP_User_Query( array( 'blog_id' => 33 ) );
```
Search users.
* **search** (*string*) – Searches for possible string matches on columns. Use of the \* wildcard before and/or after the string will match on columns starting with\*, \*ending with, or \*containing\* the string you enter.
* **search\_columns** (*array*) – List of [database table columns](https://codex.wordpress.org/Database_Description#Table:_wp_users "Database Description") to matches the search string across multiple columns.
+ ‘ID‘ – Search by user id.
+ ‘user\_login‘ – Search by user login.
+ ‘user\_nicename‘ – Search by user nicename.
+ ‘user\_email‘ – Search by user email.
+ ‘user\_url‘ – Search by user url.
We can use the [user\_search\_columns](../hooks/user_search_columns "Plugin API/Filter Reference/user search columns") filter to modify the search columns.
**Display users based on a keyword search**
```
$user_query = new WP_User_Query( array( 'search' => 'Rami' ) );
```
**Display users based on a keyword search, only on login and email columns**
```
$args = array(
'search' => 'Rami',
'search_columns' => array( 'user_login', 'user_email' )
);
$user_query = new WP_User_Query( $args );
```
Limit retrieved Users.
* **number** (*int*) – The maximum returned number of results (needed in pagination).
* **offset** (*int*) – Offset the returned results (needed in pagination).
* **paged** (*int*) – When used with number, defines the page of results to return. Default 1. (since [Version 4.4](https://codex.wordpress.org/Version_4.4 "Version 4.4")).
**Display 10 users**
```
$user_query = new WP_User_Query( array( 'number' => 10 ) );
```
**Display 5 users starting from 25**
```
$user_query = new WP_User_Query( array( 'number' => 5, 'offset' => 25 ) );
```
Sort retrieved Users.
* **orderby** (*string|array*) – Sort retrieved users by parameter. Defaults to ‘login’. It can be a string with a single field, a string containing a list of values separated by commas or spaces, or an array with fields.
+ ‘ID‘ – Order by user id.
+ ‘display\_name‘ – Order by user display name.
+ ‘name‘ / ‘user\_name‘ – Order by user name.
+ ‘include‘ – Order by the included list of user\_ids (requires the include parameter) (since [Version 4.1](https://codex.wordpress.org/Version_4.1 "Version 4.1")).
+ ‘login‘ / ‘user\_login‘ – Order by user login.
+ ‘nicename‘ / ‘user\_nicename‘ – Order by user nicename.
+ ‘email‘ / ‘user\_email‘ – Order by user email.
+ ‘url‘ / ‘user\_url‘ – Order by user url.
+ ‘registered‘ / ‘user\_registered‘ – Order by user registered date.
+ ‘post\_count‘ – Order by user post count.
+ ‘meta\_value‘ – Note that a ‘meta\_key=keyname’ must also be present in the query (available with [Version 3.7](https://codex.wordpress.org/Version_3.7 "Version 3.7")).
+ ‘meta\_value\_num‘ – Note that a ‘meta\_key=keyname’ must also be present in the query (available with [Version 4.2](https://codex.wordpress.org/Version_4.2 "Version 4.2")).
* **order** (*string*) – Designates the ascending or descending order of the ‘orderby‘ parameter. Defaults to ‘ASC’.
+ ‘ASC‘ – ascending order from lowest to highest values (1, 2, 3; a, b, c).
+ ‘DESC‘ – descending order from highest to lowest values (3, 2, 1; c, b, a).
**Display users sorted by Post Count, Descending order**
```
$user_query = new WP_User_Query( array ( 'orderby' => 'post_count', 'order' => 'DESC' ) );
```
**Display users sorted by registered, Ascending order**
```
$user_query = new WP_User_Query( array ( 'orderby' => 'registered', 'order' => 'ASC' ) );
```
Date queries are handled through to the [WP\_Date\_Query](wp_date_query) object and are applied to the user\_registered field.
Available since [version 4.1](https://codex.wordpress.org/Version_4.1).
* **date\_query** (*array*) – See the documentation for the [WP\_Query](wp_query) class.
**Find users that registered during the last 12 hours:**
```
$args = array(
'date_query' => array(
array( 'after' => '12 hours ago', 'inclusive' => true )
)
);
$user_query = new WP_User_Query( $args );
```
Show users associated with a certain custom field.
The [WP\_Meta\_Query](wp_meta_query) class is used to parse this part of the query since [3.2.0](https://codex.wordpress.org/Version_3.2 "Version 3.2"), so check the docs for that class for the full, up to date [list of arguments](wp_meta_query "Class Reference/WP Meta Query").
* **meta\_key** (*string*) – Custom field key.
* **meta\_value** (*string*) – Custom field value.
* **meta\_compare** (*string*) – Operator to test the ‘meta\_value‘. See 'compare' below.
* **meta\_query** (*array*) – Custom field parameters (available with [Version 3.5](https://codex.wordpress.org/Version_3.5 "Version 3.5")).
+ **key** (*string*) – Custom field key.
+ **value** (*string*|*array*) – Custom field value (*Note*: Array support is limited to a compare value of ‘IN’, ‘NOT IN’, ‘BETWEEN’, ‘NOT BETWEEN’, ‘EXISTS’ or ‘NOT EXISTS’)
+ **compare** (*string*) – Operator to test. Possible values are ‘=’, ‘!=’, ‘>’, ‘>=’, ‘<‘, ‘<=’, ‘LIKE’, ‘NOT LIKE’, ‘IN’, ‘NOT IN’, ‘BETWEEN’, ‘NOT BETWEEN’, ‘EXISTS’, and ‘NOT EXISTS’ ; ‘REGEXP’, ‘NOT REGEXP’ and ‘RLIKE’ were added in WordPress 3.7. Default value is ‘=’.
**Note:** Currently 'NOT EXISTS' does not always work as intended if 'relation' is 'OR' when, (1) using the ['role'](https://codex.wordpress.org/Class_Reference/WP_User_Query#User_Role_Parameter) parameter on single site installs, or (2) for any query on multisite. See [ticket #23849](https://core.trac.wordpress.org/ticket/23849).
**Note 2:** with ‘LIKE’ the value parameter is change to ‘%<value>%’. So the string is searched anywhere in the custom field value. If value parameter contain a ‘%’ it is escaped. So it bans to search a string beginning by some characters, for exemple… To construct this query you must use ‘REGEXP’ with a regular expression in value parameter (ex : ‘^n.\*’ matchs all values that beginning by “n” or “N”).
+ **type** (*string*) – Custom field type. Possible values are ‘NUMERIC’, ‘BINARY’, ‘CHAR’, ‘DATE’, ‘DATETIME’, ‘DECIMAL’, ‘SIGNED’, ‘TIME’, ‘UNSIGNED’. Default value is ‘CHAR’. You can also specify precision and scale for the ‘DECIMAL’ and ‘NUMERIC’ types (for example, ‘DECIMAL(10,5)’ or ‘NUMERIC(10)’ are valid).
**Display users from Israel**
```
$user_query = new WP_User_Query( array( 'meta_key' => 'country', 'meta_value' => 'Israel' ) );
```
**Display users under 30 years old**
```
$user_query = new WP_User_Query( array( 'meta_key' => 'age', 'meta_value' => '30', 'meta_compare' => '<' ) );
```
**Multiple custom user fields handling**
```
$args = array(
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'country',
'value' => 'Israel',
'compare' => '='
),
array(
'key' => 'age',
'value' => array( 20, 30 ),
'type' => 'numeric',
'compare' => 'BETWEEN'
)
)
);
$user_query = new WP_User_Query( $args );
```
Which users?
* **who** (*string*) – Which users to query. Currently only ‘authors’ is supported. Default is all users.
**Display only authors**
```
$user_query = new WP_User_Query( array( 'who' => 'authors' ) );
```
Equals to:
```
$args = array(
'meta_key' => 'user_level',
'meta_value' => '0',
'meta_compare' => '!=',
'blog_id' => 0
)
$user_query = new WP_User_Query( $args );
```
* **count\_total** (*boolean*) – Whether to count the total number of users found. When true (default), the total number of results for the query can be retrieved using the get\_total() method. If you don’t need the total number of results, set this to false.
* **has\_published\_posts** (*boolean / array*) – Pass an array of post types to filter results to users who have published posts in those post types. true is an alias for all public post types. Default is null. Since [Version 4.3](https://codex.wordpress.org/Version_4.3 "Version 4.3").
Set return values.
* **fields** (*string|array*) – Which fields to return. Defaults to *all*.
+ ‘ID‘ – Return an array of user id’s.
+ ‘display\_name‘ – Return an array of user display names.
+ ‘login‘ / ‘user\_login‘ – Return an array of user login names.
+ ‘nicename‘ / ‘user\_nicename‘ – Return an array of user nicenames.
+ ‘email‘ / ‘user\_email‘ – Return an array of user emails.
+ ‘url‘ / ‘user\_url‘ – Return an array of user urls.
+ ‘registered‘ / ‘user\_registered‘ – Return an array of user registered dates.
+ ‘all (default) or all\_with\_meta‘ – Returns an array of [WP\_User](https://codex.wordpress.org/Class_Reference/WP_User "Class Reference/WP User") objects. Must pass an array to subset fields returned. \*’all\_with\_meta’ currently returns the same fields as ‘all’ which does not include user fields stored in wp\_usermeta. You must create a second query to get the user meta fields by ID or use the \_\_get PHP magic method to get the values of these fields.
**Return an array of [WP\_User](wp_user) object**
```
$user_query = new WP_User_Query( array( 'role' => 'editor', 'fields' => 'all' ) );
```
**Return List all blog editors, return limited fields in resulting row objects:**
```
$user_fields = array( 'user_login', 'user_nicename', 'user_email', 'user_url' );
$user_query = new WP_User_Query( array( 'role' => 'editor', 'fields' => $user_fields ) );
```
(Array) An array of IDs, stdClass objects, or [WP\_User](https://codex.wordpress.org/Class_Reference/WP_User "Class Reference/WP User") objects, depending on the value of the ‘fields‘ parameter. * If ‘fields‘ is set to ‘all’ (default), or ‘all\_with\_meta’, it will return an array of [WP\_User](https://codex.wordpress.org/Class_Reference/WP_User "Class Reference/WP User") objects (does not include related user meta fields even with ‘all\_with\_meta’ set) .
* If ‘fields‘ is set to an array of [wp\_users](https://codex.wordpress.org/Database_Description#Table:_wp_users "Database Description") table fields, it will return an array of stdClass objects with only those fields.
* If ‘fields‘ is set to any individual [wp\_users](https://codex.wordpress.org/Database_Description#Table:_wp_users "Database Description") table field, an array of IDs will be returned.
* **[found\_users\_query](../hooks/found_users_query "Plugin API/Filter Reference/found users query (page does not exist)")** – Alters SQL ‘SELECT FOUND\_ROWS()’ clause to the query that returns the count total.

wordpress class WP_Ajax_Response {} class WP\_Ajax\_Response {}
===========================
Send XML response back to Ajax request.
[WP\_Ajax\_Response](wp_ajax_response) is WordPress’ class for generating XML-formatted responses to Ajax requests. This is most commonly used to generate responses to custom AJAX actions when using the [wp\_ajax\_](../hooks/wp_ajax_action "Plugin API/Action Reference/wp ajax (action)") action hook.
NOTE: Refer source code for the complete methods and properties.
$responses() An array that stores the XML responses to be sent. To use [WP\_Ajax\_Response](wp_ajax_response), you need to instantiate the class with an array of options, then call the instances `send()` method to output the response.
The options array takes the following key=>value pairs:
‘what’ A string containing the XMLRPC response type (used as the name of the xml element). ‘action’ A boolean or string that will behave like a nonce. This is added to the **response** element’s *action* attribute. ‘id’ This is either an integer (usually 1) or a [WP\_Error](wp_error "Function Reference/WP Error") object (if you need to return an error). Most commonly, the id value is used as a boolean, where 1 is a success and 0 is a failure. ‘old\_id’ This is `false` by default, but you can alternatively provide an integer for the previous id, if needed. ‘position’ This is an integer or a string where -1 = top, 1 = bottom, ‘html ID’ = after, ‘-html ID’ = before ‘data’ A string containing output content or a message (such as html). This is disregarded if you pass a [WP\_Error](wp_error) object as the id. ‘supplemental’ This can an associative array of strings, which will be rendered into children of the `<supplemental>` element. Keys become element names, and values are embedded in CDATA within those elements. Useful for passing additional information to the browser. Responses are made in the XML-RPC format and may be handled by JavaScript.
A typical WordPress autosave response looks like this:
```
<?xml version='1.0' standalone='yes'?>
<wp_ajax>
<response action='autosave_1'>
<autosave id='1' position='1'>
<response_data>
<![CDATA[Draft saved at 9:31:55 pm.]]>
</response_data>
<supplemental></supplemental>
</autosave>
</response>
</wp_ajax>
```
Let’s break this example down to see what it means:
<wp\_ajax> This the root element of every response. All responses made by the *[WP\_Ajax\_Response](wp_ajax_response)* class are wrapped in the `<wp_ajax>` element. <response> Immediately within the wp\_ajax element is `<response>`, which contains the attributes ‘action’ and ‘position’. These attributes correspond to the ‘action’ and ‘position’ key=>value pairs defined in the options array. <autosave> (arbitrary) Next, the above example shows an `<autosave>` element – this element matches the value of the ‘what’ key=>value pair in the options array. In your own use, **this element can be named whatever you like**, provided it is a valid XML element name. <response\_data> / <wp\_error\_data> Within the custom response element (e.g. `<autosave>`), there will either be a `<response_data>` element (with CDATA tag) or a `<wp_error_data>` element. If you pass a [WP\_Error](wp_error) object to [WP\_Ajax\_Response](wp_ajax_response) as the ‘id’ in your options array, the `<wp_error_data>` element is automatically generated. Otherwise, the `<response_data>` element is used with whatever value you passed to [WP\_Ajax\_Response](wp_ajax_response) with your option array’s “data” value. For the most part, any content you want to pass back to the browser (such as HTML), can be passed in your option array’s “data” key=>value pair. <supplemental> Finally, the `<supplemental>` element will contain whatever arbitrary structure you decide to pass along with your option array’s “supplemental” key=>value pair. * [\_\_construct](wp_ajax_response/__construct) — Constructor - Passes args to WP\_Ajax\_Response::add().
* [add](wp_ajax_response/add) — Appends data to an XML response based on given arguments.
* [send](wp_ajax_response/send) — Display XML formatted responses.

wordpress class WP_Object_Cache {} class WP\_Object\_Cache {}
==========================
Core class that implements an object cache.
The WordPress Object Cache is used to save on trips to the database. The Object Cache stores all of the cache data to memory and makes the cache contents available by using a key, which is used to name and later retrieve the cache contents.
The Object Cache can be replaced by other caching mechanisms by placing files in the wp-content folder which is looked at in wp-settings. If that file exists, then this file will not be included.
[WP\_Object\_Cache](wp_object_cache) is WordPress’ class for caching data which may be computationally expensive to regenerate, such as the result of complex database queries. The object cache is defined in `[wp-includes/cache.php](https://core.trac.wordpress.org/browser/tags/5.5.1/src/wp-includes/cache.php#L0)`.
Do not use the class directly in your code when writing plugins, but use the wp\_cache functions listed below.
By default, the object cache is non-persistent. This means that data stored in the cache resides in memory only and only for the duration of the request. Cached data will not be stored persistently across page loads unless you install a [persistent caching](wp_object_cache#persistent-caching) plugin.
Use the [Transients API](https://developer.wordpress.org/apis/handbook/transients/ "Transients API") instead of these functions if you need to guarantee that your data will be cached. If persistent caching is configured, then the transients functions will use the wp\_cache functions described in this document. However if persistent caching has not been enabled, then the data will instead be cached to the options table.
Most of these functions take a:
* $key: the key to indicate the value.
* $data: the value you want to store.
* $group: (optional) this is a way of grouping data within the cache. Allows you to use the same key across different groups.
* $expire: (optional) this defines how many seconds to keep the cache for. Only applicable to some functions. Defaults to 0 (as long as possible).
[wp\_cache\_add](../functions/wp_cache_add)
```
wp_cache_add( $key, $data, $group, $expire )
```
This function adds data to the cache if the cache key doesn’t already exist. If it does exist, the data is not added and the function returns false.
[wp\_cache\_set](../functions/wp_cache_set)
```
wp_cache_set( $key, $data, $group, $expire )
```
Adds data to the cache. If the cache key already exists, then it will be overwritten; if not then it will be created.
[wp\_cache\_get](../functions/wp_cache_get)
```
wp_cache_get( $key, $group )
wp_cache_get( $key, $group = '', $force = false, $found = null )
```
Returns the value of the cached object, or false if the cache key doesn’t exist.
To disambiguate a cached false from a non-existing key, you should do absolute testing of $found, which is passed by reference, against false: if $found === false, the key does not exist.
[wp\_cache\_delete](../functions/wp_cache_delete)
```
wp_cache_delete( $key, $group )
```
Clears data from the cache for the given key.
[wp\_cache\_replace](../functions/wp_cache_replace)
```
wp_cache_replace( $key, $data, $group, $expire )
```
Replaces the given cache if it exists, returns false otherwise. This is similar to [wp\_cache\_set()](../functions/wp_cache_set) except the cache object is not added if it doesn’t already exist.
[wp\_cache\_flush](../functions/wp_cache_flush)
```
wp_cache_flush()
```
Clears all cached data.
[wp\_cache\_add\_non\_persistent\_groups](../functions/wp_cache_add_non_persistent_groups)
```
wp_cache_add_non_persistent_groups($groups)
```
Hints to the object cache that the group or list of groups should not be cached in persistent storage. This is useful when adding items to the cache that should only be available for the duration of a script session, and not beyond. $groups can be an array of strings, or a single group name. NB: only some caching plugins implement this function!
Prior to [WordPress 2.5](https://wordpress.org/support/wordpress-version/version-2-5/ "Version 2.5"), data stored using the wp\_cache functions was stored persistently if you added define('WP\_CACHE', true) to your wp-config.php file.
This is no longer the case, **and adding the define will have no effect** unless you install a persistent cache plugin (see list below).
* [Memcached Object Cache](https://wordpress.org/extend/plugins/memcached/) provides a persistent backend for the WordPress object cache. A memcached server and the PECL memcached extension are required.
* [Redis Object Cache](https://wordpress.org/plugins/redis-cache/) supports the use of [Predis](https://github.com/nrk/predis) (PHP client library), [HHVM’s Redis extension](https://github.com/facebook/hhvm/blob/master/hphp/system/php/redis/Redis.php) and the [PECL Redis extension](https://pecl.php.net/package/redis) to provide a persistent backend for the WordPress object cache. [Redis](http://redis.io/) is required.
* [W3 Total Cache](https://wordpress.org/extend/plugins/w3-total-cache/) provides object level caching using disk, opcode or memcache(d) memory stores. Be advised that W3TC also provides: browser, page and database caching, in addition to Content Delivery Network Support, Mobile Support, Minification and more. It is not the easiest way to get object caching in WordPress.
* [LiteSpeed Cache](https://wordpress.org/plugins/litespeed-cache/) supports the use of Redis, Memcached, and LSMCD object caches. LSCWP also provides server-level full-page caching, support for browser cache and CDN, and other optimization features. But be advised that this solution requires [LiteSpeed Web Server,](https://en.wikipedia.org/wiki/LiteSpeed_Web_Server) .
The [Transients\_API](https://developer.wordpress.org/apis/handbook/transients/ "Transients API") provides persistent but temporary data caching by giving it a custom name and a timeframe after which it will be expired and regenerated.
*Note: Transients only get deleted when a request is made. So, until someone visits your page and calls up the Transient, it will stay in the DB. In short: It’s not a real persistent cache and not equal to stuff running on cron jobs.*
* The [Debug Bar](https://wordpress.org/plugins/debug-bar/) plugin helps you analyze the object cache.
* Scott Taylor’s article [WordPress + Memcached](http://scotty-t.com/2012/01/20/wordpress-memcached/) explains various cache plugins and concepts.

wordpress class WP_Meta_Query {} class WP\_Meta\_Query {}
========================
Core class used to implement meta queries for the Meta API.
Used for generating SQL clauses that filter a primary query according to metadata keys and values.
[WP\_Meta\_Query](wp_meta_query) is a helper that allows primary query classes, such as [WP\_Query](wp_query) and [WP\_User\_Query](wp_user_query),
to filter their results by object metadata, by generating `JOIN` and `WHERE` subclauses to be attached to the primary SQL query string.
[WP\_Meta\_Query](wp_meta_query) is a class defined in wp-includes/meta.php that generates the necessary SQL for meta-related queries. It was introduced in Version 3.2.0 and greatly improved the possibility to query posts by custom fields. In the WP core, it’s used in the [WP\_Query](wp_query "Class Reference/WP Query") and [WP\_User\_Query](wp_user_query "Class Reference/WP User Query") classes, and since Version 3.5 in the [WP\_Comment\_Query](wp_comment_query "Class Reference/WP Comment Query") class. Unless you’re writing a custom SQL query, you should look in the \*Custom Field Parameters\* section for the corresponding class.
The following arguments can be passed in a key=>value paired array.
* **meta\_key** (*string*) – Custom field key. ( You must sanitize this yourself )
* **meta\_value** (*string|array*) – Custom field value. ( You must sanitize this yourself )
* **meta\_type** (*string*) – Custom field type (see **type** below for options).
* **meta\_compare** (*string*) – Operator to test the 'meta\_value' (see **compare** below for possible values).
* **meta\_query** (*array*) – Contains one or more arrays with the following keys:
+ **key** (*string*) – Custom field key.
+ **value** (*string*|*array*) – Custom field value. It can be an array only when **compare** is 'IN', 'NOT IN', 'BETWEEN', or 'NOT BETWEEN'. You don’t have to specify a value when using the 'EXISTS' or 'NOT EXISTS' comparisons in WordPress 3.9 and up.
(**Note:** Due to [bug #23268](https://core.trac.wordpress.org/ticket/23268), value was required for NOT EXISTS comparisons to work correctly prior to 3.9. You had to supply *some* string for the value parameter. An empty string or NULL will NOT work. However, any other string will do the trick and will NOT show up in your SQL when using NOT EXISTS. Need inspiration? How about 'bug #23268'.)
+ **compare** (*string*) – Operator to test. Possible values are ‘=’, ‘!=’, ‘>’, ‘>=’, ‘<‘, ‘<=’, ‘LIKE’, ‘NOT LIKE’, ‘IN’, ‘NOT IN’, ‘BETWEEN’, ‘NOT BETWEEN’, ‘EXISTS’ (only in WP >= 3.5), and ‘NOT EXISTS’ (also only in WP >= 3.5). Values ‘REGEXP’, ‘NOT REGEXP’ and ‘RLIKE’ were added in WordPress 3.7. Default value is ‘=’.
+ **type** (*string*) – Custom field type. Possible values are ‘NUMERIC’, ‘BINARY’, ‘CHAR’, ‘DATE’, ‘DATETIME’, ‘DECIMAL’, ‘SIGNED’, ‘TIME’, ‘UNSIGNED’. Default value is ‘CHAR’.
The 'type' DATE works with the 'compare' value BETWEEN only if the date is stored at the format YYYY-MM-DD and tested with this format.
*Note:* The 'meta\_key', 'meta\_value', 'meta\_type' and 'meta\_compare' arguments will only work if you use the second method described below.
* [\_\_construct](wp_meta_query/__construct) — Constructor.
* [find\_compatible\_table\_alias](wp_meta_query/find_compatible_table_alias) — Identify an existing table alias that is compatible with the current query clause.
* [get\_cast\_for\_type](wp_meta_query/get_cast_for_type) — Return the appropriate alias for the given meta type if applicable.
* [get\_clauses](wp_meta_query/get_clauses) — Get a flattened list of sanitized meta clauses.
* [get\_sql](wp_meta_query/get_sql) — Generates SQL clauses to be appended to a main query.
* [get\_sql\_clauses](wp_meta_query/get_sql_clauses) — Generate SQL clauses to be appended to a main query.
* [get\_sql\_for\_clause](wp_meta_query/get_sql_for_clause) — Generate SQL JOIN and WHERE clauses for a first-order query clause.
* [get\_sql\_for\_query](wp_meta_query/get_sql_for_query) — Generate SQL clauses for a single query array.
* [has\_or\_relation](wp_meta_query/has_or_relation) — Checks whether the current query has any OR relations.
* [is\_first\_order\_clause](wp_meta_query/is_first_order_clause) — Determine whether a query clause is first-order.
* [parse\_query\_vars](wp_meta_query/parse_query_vars) — Constructs a meta query based on 'meta\_\*' query vars
* [sanitize\_query](wp_meta_query/sanitize_query) — Ensure the 'meta\_query' argument passed to the class constructor is well-formed.

| Version | Description |
| --- | --- |
| [4.8.1](https://developer.wordpress.org/reference/since/4.8.1/) | Introduced. |
wordpress class WP_Widget {} class WP\_Widget {}
===================
Core base class extended to register widgets.
This class must be extended for each widget, and [WP\_Widget::widget()](wp_widget/widget) must be overridden.
If adding widget options, [WP\_Widget::update()](wp_widget/update) and [WP\_Widget::form()](wp_widget/form) should also be overridden.
* [\_\_construct](wp_widget/__construct) — PHP5 constructor.
* [\_get\_display\_callback](wp_widget/_get_display_callback) — Retrieves the widget display callback.
* [\_get\_form\_callback](wp_widget/_get_form_callback) — Retrieves the form callback.
* [\_get\_update\_callback](wp_widget/_get_update_callback) — Retrieves the widget update callback.
* [\_register](wp_widget/_register) — Register all widget instances of this widget class.
* [\_register\_one](wp_widget/_register_one) — Registers an instance of the widget class.
* [\_set](wp_widget/_set) — Sets the internal order number for the widget instance.
* [display\_callback](wp_widget/display_callback) — Generates the actual widget content (Do NOT override).
* [form](wp_widget/form) — Outputs the settings update form.
* [form\_callback](wp_widget/form_callback) — Generates the widget control form (Do NOT override).
* [get\_field\_id](wp_widget/get_field_id) — Constructs id attributes for use in WP\_Widget::form() fields.
* [get\_field\_name](wp_widget/get_field_name) — Constructs name attributes for use in form() fields
* [get\_settings](wp_widget/get_settings) — Retrieves the settings for all instances of the widget class.
* [is\_preview](wp_widget/is_preview) — Determines whether the current request is inside the Customizer preview.
* [save\_settings](wp_widget/save_settings) — Saves the settings for all instances of the widget class.
* [update](wp_widget/update) — Updates a particular instance of a widget.
* [update\_callback](wp_widget/update_callback) — Handles changed settings (Do NOT override).
* [widget](wp_widget/widget) — Echoes the widget content.
* [WP\_Widget](wp_widget/wp_widget) — PHP4 constructor. — deprecated

wordpress class Walker {} class Walker {}
===============
A class for displaying various tree-like structures.
Extend the [Walker](walker) class to use it, see examples below. Child classes do not need to implement all of the abstract methods in the class. The child only needs to implement the methods that are needed.
The [Walker](walker) class was implemented in [WordPress 2.1](https://codex.wordpress.org/Version_2.1 "Version 2.1") to provide developers with a means to traverse tree-like data structures for the purpose of rendering HTML.
In terms of web development, a tree-like structure is an array or object with hierarchical data – such that it can be visually represented with a root element and subtrees of children.
Examples of WordPress objects with data that are structured in a “tree-like” way include navigational menus, page categories, and breadcrumbs.
[Walker](walker) is an *[abstract](http://php.net/manual/en/language.oop5.abstract.php)* class. In order to be useful the class must be [extended](http://php.net/manual/en/reflection.extending.php) and any necessary abstract methods defined (see “Abstract Methods” below for more).
The class itself simply “walks” through each node in a tree (e.g. an object or associative array) and executes an abstract function at each node. In order to take an action at one of these nodes, a developer must define those abstract methods within a custom child class.
Although the [Walker](walker) class has many uses, one of the most common usages by developers is outputting HTML for custom menus (usually ones that have been defined using the [Appearance → Menus](https://wordpress.org/support/article/appearance-menus-screen/ "Appearance Menus Screen") screen in the [Administration Screens](https://wordpress.org/support/article/administration-screens/ "Administration Screens")).
**Abstraction Note:** The [Walker](walker) class was created *prior* to PHP5 and so does **not** make use of PHP5’s explicit abstraction keywords or features. In this case, the class and its methods are *implicitly* abstract (PHP4 compatible) and **not** *explicitly* abstract (PHP5 compatible). Developers are not required to implement any methods of the class, and may use or override only those methods that are needed. If you chose not to extend a specific abstract method, that method will simply do nothing.
Please refer source code for the complete lists of methods and properties. Below description may cover some of them.
Note that the properties of the [Walker](walker) class are intended to be set by the extending class and probably should not vary over the lifetime of an instance.
$db\_fields
**Required**. Because [Walker](walker) can take any type of tree object, you need to specify what object properties the [Walker](walker) class should treat as parent id and item id (usually these are the names of database fields, hence the property name). This property **must** be an associative array with two keys: `'parent'` and `'id'`. The value of each key should be the names of the object properties that hold the *parent id* and *item id*, respectively. $tree\_type Optional. The [Walker](walker) class itself makes no use of this value, although it may be useful to developers. Internally, WordPress’s own extended [Walker](walker) classes will set this to values like ‘category’ or ‘page’. $max\_pages Optional. The maximum number of pages walked by the paged walker. There are two general use-cases for the [Walker](walker) class.
Some WordPress APIs and functions ( such as [wp\_nav\_menu()](../functions/wp_nav_menu) ) allow developers to specify a custom [Walker](walker) class as a callback. This is the most common usage of the [Walker](walker) class by developers.
In this scenario, the class is automatically passed a tree of elements. When creating a custom walker for this scenario, you will generally only need to define the **abstract** methods needed to create the kind of structure you want. Everything else is handled automatically for you.
It is also possible to call your custom [Walker](walker) classes manually. This is particularly useful for plugin developers.
In this scenario, you can initiate the walker by calling either the walk() or paged\_walk() method of your child class, with the appropriate parameters.
* [display\_element](walker/display_element) — Traverses elements to create list from elements.
* [end\_el](walker/end_el) — Ends the element output, if needed.
* [end\_lvl](walker/end_lvl) — Ends the list of after the elements are added.
* [get\_number\_of\_root\_elements](walker/get_number_of_root_elements) — Calculates the total number of root elements.
* [paged\_walk](walker/paged_walk) — Produces a page of nested elements.
* [start\_el](walker/start_el) — Starts the element output.
* [start\_lvl](walker/start_lvl) — Starts the list before the elements are added.
* [unset\_children](walker/unset_children) — Unsets all the children for a given top level element.
* [walk](walker/walk) — Displays array of elements hierarchically.

* [find\_compatible\_table\_alias](wp_tax_query/find_compatible_table_alias) — Identifies an existing table alias that is compatible with the current query clause.
* [get\_sql](wp_tax_query/get_sql) — Generates SQL clauses to be appended to a main query.
* [get\_sql\_clauses](wp_tax_query/get_sql_clauses) — Generates SQL clauses to be appended to a main query.
* [get\_sql\_for\_clause](wp_tax_query/get_sql_for_clause) — Generates SQL JOIN and WHERE clauses for a "first-order" query clause.
* [get\_sql\_for\_query](wp_tax_query/get_sql_for_query) — Generates SQL clauses for a single query array.
* [is\_first\_order\_clause](wp_tax_query/is_first_order_clause) — Determines whether a clause is first-order.
* [sanitize\_query](wp_tax_query/sanitize_query) — Ensures the 'tax\_query' argument passed to the class constructor is well-formed.
* [sanitize\_relation](wp_tax_query/sanitize_relation) — Sanitizes a 'relation' operator.
* [transform\_query](wp_tax_query/transform_query) — Transforms a single query, from one field to another.

wordpress class WP_Dependencies {} class WP\_Dependencies {}
=========================
Core base class extended to register items.
* [\_WP\_Dependency](_wp_dependency)
`WP_Dependencies` is a class defined in `[wp-includes/class.wp-dependencies.php](https://core.trac.wordpress.org/browser/tags/5.5/src/wp-includes/class.wp-dependencies.php#L0)` that helps process items in an order defined by dependencies (a dependent item is processed later than a dependency). It’s an abstract class in that it’s intended to be extended, rather than used directly. `WP_Dependencies` is the base for `[WP\_Scripts](wp_scripts "Class Reference/WP Scripts (page does not exist)")` and `[WP\_Styles](wp_styles "Class Reference/WP Styles")`, and is a collection of `[\_WP\_Dependency](_wp_dependency "Class Reference/ WP Dependency")`s.
An item goes through various stages of processing as various methods are called:
1. registered: `add()`
2. enqueued: `enqueue()`
3. to\_do: `all_deps()`
4. done: `do_items()`
The `query()` method can be used to determine whether a given item is in a given stage.
Separate processing runs can be identified by different groups (identified by integers). For example, items output in the document <head> might go in one group, while items output in the footer may go in another. An enqueued item that was processed in a group associated with an earlier run is skipped in later runs. The base `WP_Dependencies` doesn’t create groups on its own; child classes must do this.
* [add](wp_dependencies/add) — Register an item.
* [add\_data](wp_dependencies/add_data) — Add extra item data.
* [all\_deps](wp_dependencies/all_deps) — Determines dependencies.
* [dequeue](wp_dependencies/dequeue) — Dequeue an item or items.
* [do\_item](wp_dependencies/do_item) — Processes a dependency.
* [do\_items](wp_dependencies/do_items) — Processes the items and dependencies.
* [enqueue](wp_dependencies/enqueue) — Queue an item or items.
* [get\_data](wp_dependencies/get_data) — Get extra item data.
* [query](wp_dependencies/query) — Query the list for an item.
* [recurse\_deps](wp_dependencies/recurse_deps) — Recursively search the passed dependency tree for a handle.
* [remove](wp_dependencies/remove) — Un-register an item or items.
* [set\_group](wp_dependencies/set_group) — Set item group, unless already in a lower group.

wordpress class WP_Theme_JSON_Resolver {} class WP\_Theme\_JSON\_Resolver {}
==================================
Class that abstracts the processing of the different data sources for site-level config and offers an API to work with them.
This class is for internal core usage and is not supposed to be used by extenders (plugins and/or themes).
This is a low-level API that may need to do breaking changes. Please, use get\_global\_settings, get\_global\_styles, and get\_global\_stylesheet instead.
* [clean\_cached\_data](wp_theme_json_resolver/clean_cached_data) — Cleans the cached data so it can be recalculated.
* [extract\_paths\_to\_translate](wp_theme_json_resolver/extract_paths_to_translate) — Converts a tree as in i18n-theme.json into a linear array containing metadata to translate a theme.json file.
* [get\_block\_data](wp_theme_json_resolver/get_block_data) — Gets the styles for blocks from the block.json file.
* [get\_core\_data](wp_theme_json_resolver/get_core_data) — Returns core's origin config.
* [get\_fields\_to\_translate](wp_theme_json_resolver/get_fields_to_translate) — Returns a data structure used in theme.json translation. — deprecated
* [get\_file\_path\_from\_theme](wp_theme_json_resolver/get_file_path_from_theme) — Builds the path to the given file and checks that it is readable.
* [get\_merged\_data](wp_theme_json_resolver/get_merged_data) — Returns the data merged from multiple origins.
* [get\_style\_variations](wp_theme_json_resolver/get_style_variations) — Returns the style variations defined by the theme.
* [get\_theme\_data](wp_theme_json_resolver/get_theme_data) — Returns the theme's data.
* [get\_user\_data](wp_theme_json_resolver/get_user_data) — Returns the user's origin config.
* [get\_user\_data\_from\_wp\_global\_styles](wp_theme_json_resolver/get_user_data_from_wp_global_styles) — Returns the custom post type that contains the user's origin config for the active theme or a void array if none are found.
* [get\_user\_global\_styles\_post\_id](wp_theme_json_resolver/get_user_global_styles_post_id) — Returns the ID of the custom post type that stores user data.
* [has\_same\_registered\_blocks](wp_theme_json_resolver/has_same_registered_blocks) — Checks whether the registered blocks were already processed for this origin.
* [read\_json\_file](wp_theme_json_resolver/read_json_file) — Processes a file that adheres to the theme.json schema and returns an array with its contents, or a void array if none found.
* [remove\_json\_comments](wp_theme_json_resolver/remove_json_comments) — When given an array, this will remove any keys with the name `//`.
* [theme\_has\_support](wp_theme_json_resolver/theme_has_support) — Determines whether the active theme has a theme.json file.
* [translate](wp_theme_json_resolver/translate) — Given a theme.json structure modifies it in place to update certain values by its translated strings according to the language set by the user.
* [translate\_theme\_json\_chunk](wp_theme_json_resolver/translate_theme_json_chunk) — Translates a chunk of the loaded theme.json structure.

wordpress class WP_Admin_Bar {} class WP\_Admin\_Bar {}
=======================
Core class used to implement the Toolbar API.
[WP\_Admin\_Bar](wp_admin_bar) is WordPress’ class for generating the Toolbar that lines the top of WordPress sites when signed in. This class can be hooked and modified to add or remove options that appear in the admin bar.
The Toolbar replaces the Admin Bar since WordPress [Version 3.3](https://wordpress.org/support/wordpress-version/version-3-3/ "Version 3.3").
This class is used internally by WordPress to create an object called **$wp\_admin\_bar**. Most modifications to WordPress toolbar will generally be done by modifying the $wp\_admin\_bar object that is passed through the [admin\_bar\_menu](../hooks/admin_bar_menu "Plugin API/Action Reference/admin bar menu (page does not exist)") hook.
Example:
```
add_action( 'admin_bar_menu', 'modify_admin_bar' );
function modify_admin_bar( $wp_admin_bar ){
// do something with $wp_admin_bar;
}
```

wordpress class wpdb {} class wpdb {}
=============
An instantiated *<wpdb>* class can talk to any number of tables, but only to one database at a time. In the rare case you need to connect to another database, instantiate your own object from the *<wpdb>* class with your own database connection information.
**Note:** Each method contained within the class is listed in the Methods section (below). In addition, each method has its own help page; this is where you’ll find detailed usage information for the method you’re interested in.
Some of the methods in this class take an SQL statement as input. **All untrusted values in an SQL statement m****ust be escaped** to prevent SQL injection attacks. Some methods will escape SQL for you; others will not. Check the documentation to be sure before you use any method in this class. For more on SQL escaping in WordPress, see the section entitled Protect Queries Against SQL Injection Attacks below.
WordPress provides a global object, `$wpdb`, which is an instantiation of the *<wpdb>* class. By default, `$wpdb` is instantiated to talk to the WordPress database.
The recommended way to access `$wpdb` in your WordPress PHP code is to declare `$wpdb` as a global variable using the [`global` keyword](http://www.php.net/manual/en/language.variables.scope.php#language.variables.scope.global), like this:

// 1st Method - Declaring $wpdb as global and using it to execute an SQL query statement that returns a PHP object
global $wpdb;
$results = $wpdb->get_results( "SELECT * FROM {$wpdb->prefix}options WHERE option_id = 1", OBJECT );
```
Alternatively, if the above doesn’t suit your needs for whatever reason, use the [superglobal `$GLOBALS`](http://www.php.net/manual/en/language.variables.superglobals.php) in the following manner:
```
<?php
// 2nd Method - Utilizing the $GLOBALS superglobal. Does not require global keyword ( but may not be best practice )
$results = $GLOBALS['wpdb']->get_results( "SELECT * FROM {$wpdb->prefix}options WHERE option_id = 1", OBJECT );
```
The `$wpdb` object can be used to read data from *any* table in the WordPress database, not just those created by WordPress itself.
> For a more complete overview of SQL escaping in WordPress, see [database Data Validation](https://codex.wordpress.org/Data_Validation#Database "Data Validation"). It is a **must-read** for all WordPress code contributors and plugin authors.

All data in SQL queries must be SQL-escaped before the SQL query is executed to prevent against SQL injection attacks. The `prepare` method performs this functionality for WordPress, which supports both a [sprintf()](http://php.net/sprintf)-like and [vsprintf()](http://php.net/vsprintf)-like syntax.
Using it looks like this:
```
<?php
$sql = $wpdb->prepare( 'query' , value_parameter[, value_parameter ... ] );
```
`query`
*(string)* The SQL query you wish to execute, with placeholders (see below). `value_parameter`
*(int|string|array)* The value to substitute into the placeholder. Many values may be passed by simply passing more arguments in a [sprintf()](http://php.net/sprintf)-like fashion. Alternatively the second argument can be an array containing the values as in PHP’s [vsprintf()](http://php.net/vsprintf) function. Care must be taken not to allow direct user input to this parameter, which would enable array manipulation of any query with multiple placeholders.**Note:** Values cannot be SQL-escaped. The `query` parameter for `prepare` accepts [sprintf()](http://php.net/sprintf)-like placeholders:
* `%s` (string)
* `%d` (integer)
* `%f` (float)
Notes on placeholders
1. Any other `%` characters may cause parsing errors unless they are escaped.
2. All `%` characters inside SQL string literals, including LIKE wildcards, must be double-% escaped as `%%`.
3. Leave `%d`, `%f`, and `%s` unquoted in the query string.
Add Meta key => value pair “Funny Phrases” => “WordPress’ database interface is like Sunday Morning: Easy.” to Post 10.
```
<?php
$metakey = 'Funny Phrases';
$metavalue = "WordPress' database interface is like Sunday Morning: Easy.";
$wpdb->query(
$wpdb->prepare(
"INSERT INTO $wpdb->postmeta
( post_id, meta_key, meta_value )
VALUES ( %d, %s, %s )",
10,
$metakey,
$metavalue
)
);
```
The same query using [vsprintf()](http://php.net/vsprintf)-like syntax. Note that in this example we pack the values together in an array. This can be useful when we don’t know the number of arguments we need to pass until runtime.
```
<?php
$metakey = 'Funny Phrases';
$metavalue = "WordPress' database interface is like Sunday Morning: Easy.";
$wpdb->query(
$wpdb->prepare(
"INSERT INTO $wpdb->postmeta
( post_id, meta_key, meta_value )
VALUES ( %d, %s, %s )",
array(
10,
$metakey,
$metavalue,
)
)
);
```
In both cases, we do not need to escape the strings because we are passing them using placeholders. You can pass as many values as you like, provided each one has a corresponding placeholder in the `prepare()` method call.
Each of the class’s properties and methods are listed below, and most have their own help page that you should consult for detailed usage information. This section, however, gives an overview of some of the more common tasks this class can be used to perform.
The [`get_var`](wpdb/get_var) function returns a single variable from the database. Though only one variable is returned, the entire result of the query is cached for later use. Returns NULL if no result is found.
```
<?php $wpdb->get_var( 'query', column_offset, row_offset ); ?>
```
**`query`**
*(string)* The query you wish to run. Setting this parameter to `null` will return the specified variable from the cached results of the previous query. **`column_offset`**
*(integer)* The desired column (0 being the first). Defaults to 0. **`row_offset`**
*(integer)* The desired row (0 being the first). Defaults to 0. Retrieve and display the number of users.
```
<?php
$user_count = $wpdb->get_var( "SELECT COUNT(*) FROM $wpdb->users" );
echo "<p>User count is {$user_count}</p>";
?>
```
Retrieve and display the sum of a Custom Field value.
```
<?php
// set the meta_key to the appropriate custom field meta key
$meta_key = 'miles';
$allmiles = $wpdb->get_var(
$wpdb->prepare(
"
SELECT sum(meta_value)
FROM $wpdb->postmeta
WHERE meta_key = %s
",
$meta_key
)
);
echo "<p>Total miles is {$allmiles}</p>";
?>
```
To retrieve an entire row from a query, use [`get_row`](wpdb/get_row). The function can return the row as an object, an associative array, or as a numerically indexed array. If more than one row is returned by the query, only the specified row is returned by the function, but all rows are cached for later use. Returns `null` if no result is found, consider this when using the returned value in arguments, see example below.
```
<?php $wpdb->get_row('query', output_type, row_offset); ?>
```
**`query`**
*(string)* The query you wish to run. **`output_type`** One of three pre-defined constants. Defaults to `OBJECT`. * `OBJECT` – result will be output as an object.
* `ARRAY_A` – result will be output as an associative array.
* `ARRAY_N` – result will be output as a numerically indexed array.
**`row_offset`**
*(integer)* The desired row (0 being the first). Defaults to 0. Get all the information about Link 10.
```
$mylink = $wpdb->get_row( "SELECT * FROM $wpdb->links WHERE link_id = 10" );
```
The properties of the <code>$mylink</code> object are the column names of the result from the SQL query (in this example all the columns from the <code>$<wpdb>->links</code> table, but you could also query for specific columns only).
```
echo $mylink->link_id; // prints "10"
```
In contrast, using
```
$mylink = $wpdb->get_row( "SELECT * FROM $wpdb->links WHERE link_id = 10", ARRAY_A );
```
would result in an associative array:
```
echo $mylink['link_id']; // prints "10"
```
and
```
$mylink = $wpdb->get_row( "SELECT * FROM $wpdb->links WHERE link_id = 10", ARRAY_N );
```
would result in a numerically indexed array:
```
echo $mylink[1]; // prints "10"
```
If there is no record with ID 10 in the links table, `null` will be returned. The following would then be false:
```
if ( null !== $mylink ) {
// do something with the link
return true;
} else {
// no link found
return false;
}
```
To SELECT a column, use [`get_col`](wpdb/get_col). This method outputs a one dimensional array. If more than one column is returned by the query, only the specified column will be returned, but the entire result is cached for later use. Returns an empty array if no result is found.
```
get_col( 'query', column_offset ); ?>
```
**`query`**
*(string)* the query you wish to execute. Setting this parameter to `null` will return the specified column from the cached results of the previous query. **`column_offset`**
*(integer)* The desired column (0 being the first). Defaults to 0. For this example, assume the blog is devoted to information about automobiles. Each post describes a particular car (e.g. 1969 Ford Mustang), and three Custom Fields, manufacturer, model, and year, are assigned to each post. This example will display the post titles, filtered by a particular manufacturer (Ford), and sorted by model and year.
The **get\_col** method is used to return an array of all the post ids meeting the criteria and sorted in the correct order. Then a `foreach` construct is used to iterate through that array of post ids, displaying the title of each post. Note that the SQL for this example was created by [Andomar](http://stackoverflow.com/questions/1690762/complicated-mysql-query/1690808#1690808).
```
<?php
$meta_key1 = 'model';
$meta_key2 = 'year';
$meta_key3 = 'manufacturer';
$meta_key3_value = 'Ford';
$postids = $wpdb->get_col( $wpdb->prepare(
"
SELECT key3.post_id
FROM $wpdb->postmeta key3
INNER JOIN $wpdb->postmeta key1
ON key1.post_id = key3.post_id
AND key1.meta_key = %s
INNER JOIN $wpdb->postmeta key2
ON key2.post_id = key3.post_id
AND key2.meta_key = %s
WHERE key3.meta_key = %s
AND key3.meta_value = %s
ORDER BY key1.meta_value, key2.meta_value
",
$meta_key1,
$meta_key2,
$meta_key3,
$meta_key3_value
) );
if ( $postids ) {
echo "List of {$meta_key3_value}(s), sorted by {$meta_key1}, {$meta_key2}";
foreach ( $postids as $id ) {
$post = get_post( intval( $id ) );
setup_postdata( $post );
?>
<p>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_title(); ?>
</a>
</p>
<?php
}
}
?>
```
This example lists all posts that contain a particular custom field, but sorted by the value of a second custom field.
```
<?php
// List all posts with custom field Color, sorted by the value of custom field Display_Order
// does not exclude any 'post_type'
// assumes each post has just one custom field for Color, and one for Display_Order
$meta_key1 = 'Color';
$meta_key2 = 'Display_Order';
$postids = $wpdb->get_col( $wpdb->prepare(
"
SELECT key1.post_id
FROM $wpdb->postmeta key1
INNER JOIN $wpdb->postmeta key2
ON key2.post_id = key1.post_id
AND key2.meta_key = %s
WHERE key1.meta_key = %s
ORDER BY key2.meta_value+(0) ASC
",
$meta_key2,
$meta_key1
) );
if ( $postids ) {
echo "List of {$meta_key1} posts, sorted by {$meta_key2}";
foreach ( $postids as $id ) {
$post = get_post( intval( $id ) );
setup_postdata( $post );
?>
<p>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_title(); ?>
</a>
</p>
<?php
}
}
?>
```
Generic, multiple row results can be pulled from the database with [`get_results`](wpdb/get_results). The method returns the entire query result as an array. Each element of this array corresponds to one row of the query result and, like `get_row`, can be an object, an associative array, or a numbered array. If no matching rows are found, or if there is a database error, the return value will be an empty array. If your `$query` string is empty, or you pass an invalid `$output_type`, `NULL` will be returned.
```
get_results( 'query', output_type );
```
**`query`**
*(string)* The query you wish to run. **`output_type`** One of four pre-defined constants. Defaults to `OBJECT`. See [SELECT a Row](https://codex.wordpress.org/Class_Reference/wpdb#SELECT_a_Row) and its examples for more information. * **`OBJECT`** – result will be output as a numerically indexed array of row objects.
* **`OBJECT_K`** – result will be output as an associative array of row objects, using first column’s values as keys (duplicates will be discarded).
* **`ARRAY_A`** – result will be output as a numerically indexed array of associative arrays, using column names as keys.
* **`ARRAY_N`** – result will be output as a numerically indexed array of numerically indexed arrays.
Since this method uses the `$wpdb->query()` method, all the class variables are properly set. The results count for a ‘SELECT’ query will be stored in `$wpdb->num_rows`.
Get the IDs and Titles of all the Drafts by User 5 and echo the Titles.
```
$fivesdrafts = $wpdb->get_results(
"
SELECT ID, post_title
FROM $wpdb->posts
WHERE post_status = 'draft'
AND post_author = 5
"
);
foreach ( $fivesdrafts as $fivesdraft ) {
echo $fivesdraft->post_title;
}
```
Get all information on the Drafts by User 5.
```
<?php
$fivesdrafts = $wpdb->get_results(
"
SELECT *

WHERE post_status = 'draft'
AND post_author = 5
"
);
if ( $fivesdrafts ) {
foreach ( $fivesdrafts as $post ) {
setup_postdata( $post );
?>
<h2>
<a href="<?php the_permalink(); ?>" rel="bookmark" title="Permalink: <?php the_title(); ?>">
<?php the_title(); ?>
</a>
</h2>
<?php
}
} else {
?>
<h2>Not Found</h2>
<?php
}
?>
```
The [`insert`](wpdb/insert) method is used to insert a row into a table.
```
insert( $table, $data, $format );
```
**`$table`**
*(string)* The name of the table to insert data into. **`$data`**
*(array)* Data to insert (in column => value pairs). Both `$data` columns and `$data` values should be “raw” (neither should be SQL escaped). **`$format`**
*(array|string)* *(optional)* An array of formats to be mapped to each of the values in `$data`. If string, that format will be used for all of the values in `$data`. If omitted, all values in `$data` will be treated as strings unless otherwise specified in `wpdb::$field_types`. Possible format values: `%s` as string; `%d` as integer (whole number); and `%f` as float. (See [below](https://codex.wordpress.org/Class_Reference/wpdb#Placeholders) for more information.)
**Note:** After insert, the ID generated for the `AUTO_INCREMENT` column can be accessed with:
```
$wpdb->insert_id
```
This method returns `false` if the row could not be inserted. Otherwise, it returns the number of affected rows (which will always be 1).
**Please note**: The value portion of the data parameter’s column=>value pairs must be scalar. If you pass an array (or object) as a value to be inserted you will generate a warning.
Insert two columns in a row, the first value being a string and the second a number:
```
$wpdb->insert(
'table',
array(
'column1' => 'value1',
'column2' => 123,
),
array(
'%s',
'%d',
)
);
```
The [`replace`](wpdb/replace) method replaces a row in a table if it exists or inserts a new row in a table if the row did not already exist.
```
replace( $table, $data, $format );
```
**`$table`**
*(string)* The name of the table to replace data in. **`$data`**
*(array)* Data to replace (in column => value pairs). Both `$data` columns and `$data` values should be “raw” (neither should be SQL escaped). **`$format`**
*(array|string)* *(optional)* An array of formats to be mapped to each of the value in `$data`. If string, that format will be used for all of the values in `$data`. If omitted, all values in `$data` will be treated as strings unless otherwise specified in `wpdb::$field_types`. Possible format values: `%s` as string; `%d` as integer (whole number); and `%f` as float. (See [below](https://codex.wordpress.org/Class_Reference/wpdb#Placeholders) for more information.) If the length of a string element in the `$data` array parameter is longer that the defined length in the MySql database table, the insert will fail, this method will return `false`, but $<wpdb>->last\_error will not be set to a descriptive message. You must ensure the data you wish to insert will fit in the database – do not assume the MySql will truncate the data.
After replace, the ID generated for the `AUTO_INCREMENT` column can be accessed with:
```
$wpdb->insert_id
```
This method returns a count to indicate the number of rows affected. This is the sum of the rows deleted and inserted. If the count is 1 for a single-row REPLACE, a row was inserted and no rows were deleted. If the count is greater than 1, one or more old rows were deleted before the new row was inserted. It is possible for a single row to replace more than one old row if the table contains multiple unique indexes and the new row duplicates values for different old rows in different unique indexes.
This method returns `false` if an existing row could not be replaced and a new row could not be inserted.
Replace a row, the first value being the row id, the second a string and the third a number:
```
$wpdb->replace(
'table',
array(
'indexed_id' => 1,
'column1' => 'value1',
'column2' => 123,
),
array(
'%d',
'%s',
'%d',
)
);
```
Update a row in the table. Returns `false` if errors, or the number of rows affected if successful. ([`wpdb::update`](wpdb/update))
```
update( $table, $data, $where, $format = null, $where_format = null );
```
**`$table`**
*(string)* The name of the table to update. **`$data`**
*(array)* Data to update (in `column => value` pairs). Both `$data` columns and `$data` values should be “raw” (neither should be SQL escaped). This means that if you are using `GET` or `POST` data you may need to use `stripslashes()` to avoid slashes ending up in the database. **`$where`**
*(array)* A named array of `WHERE` clauses (in `column => value` pairs). Multiple clauses will be joined with `AND`s. Both `$where` columns and `$where` values should be “raw”. **`$format`**
*(array|string)* *(optional)* An array of formats to be mapped to each of the values in `$data`. If string, that format will be used for all of the values in `$data`. **`$where_format`**
*(array|string)* *(optional)* An array of formats to be mapped to each of the values in `$where`. If string, that format will be used for all of the items in `$where`. Possible format values: `%s` as string; `%d` as integer (whole number) and `%f` as float. (See [below](https://codex.wordpress.org/Class_Reference/wpdb#Placeholders) for more information.) If omitted, all values in `$where` will be treated as strings. This method returns the number of rows updated, or `false` if there is an error. Keep in mind that if the `$data` matches what is already in the database, no rows will be updated, so `0` will be returned. Because of this, you should probably check the return with `false === $result`
Update a row, where the ID is 1, the value in the first column is a string and the value in the second column is a number:
```
$wpdb->update(
'table',
array(
'column1' => 'value1', // string
'column2' => 'value2' // integer (number)
),
array( 'ID' => 1 ),
array(
'%s', // value1
'%d' // value2
),
array( '%d' )
);
```
**Attention:** `%d` can’t deal with comma values – if you’re *not* using full numbers, use string/`%s`.
The [`delete`](wpdb/delete) method is used to delete rows from a table. The usage is very similar to `update` and `insert`. It returns the number of rows updated, or `false` on error.
```
delete( $table, $where, $where_format = null );
```
**`$table`** (*string*) (*required*) Table name.Default: *None*
**`$where`** (*array*) (*required*) A named array of `WHERE` clauses (in column -> value pairs). Multiple clauses will be joined with `AND`s. Both `$where` columns and `$where` values should be ‘raw’. Default: *None*
**`$where_format`** (*string/array*) (*optional*) An array of formats to be mapped to each of the values in `$where`. If a string, that format will be used for all of the items in `$where`. A format is one of `'%d'`, `'%f'`, `'%s'` (integer, float, string; see [below](https://codex.wordpress.org/Class_Reference/wpdb#Placeholders) for more information). If omitted, all values in `$where` will be treated as strings unless otherwise specified in `wpdb::$field_types`. Default: `null`
```
// Default usage.
$wpdb->delete( 'table', array( 'ID' => 1 ) );
// Using where formatting.
$wpdb->delete( 'table', array( 'ID' => 1 ), array( '%d' ) );
```
The `query` method allows you to execute any SQL query on the WordPress database. It is best used when there is a need for specific, custom, or otherwise complex SQL queries. For more basic queries, such as selecting information from a table, see the other `wpdb` methods above such as `get_results, get_var, get_row or get_col`.
```
query('query');
```
**`query`**
*(string)* The SQL query you wish to execute. This method returns an integer value indicating the number of rows affected/selected for SELECT, INSERT, DELETE, UPDATE, etc. For CREATE, ALTER, TRUNCATE and DROP SQL statements, (which affect whole tables instead of specific rows) this method returns `TRUE` on success. If a MySQL error is encountered, the method will return `FALSE`. Note that since both 0 and `FALSE` may be returned for row queries, you should be careful when checking the return value. Use the identity operator (`===`) to check for errors (e.g., `false === $result`), and whether any rows were affected (e.g., `0 === $result`).
Delete the ‘gargle’ meta key and value from Post 13. (We’ll add the ‘prepare’ method to make sure we’re not dealing with an illegal operation or any illegal characters):
```
$wpdb->query(
$wpdb->prepare(
"
DELETE FROM $wpdb->postmeta
WHERE post_id = %d
AND meta_key = %s
",
13, 'gargle'
)
);
```
Set the parent of Page 15 to Page 7.
```
$wpdb->query( $wpdb->prepare(
"
UPDATE $wpdb->posts
SET post_parent = %d
WHERE ID = %d
AND post_status = %s
",
7, 15, 'static'
) );
```
You can turn error echoing on and off with the show\_errors and hide\_errors, respectively.
```
<?php $wpdb->show_errors(); ?>
<?php $wpdb->hide_errors(); ?>
```
You can also print the error (if any) generated by the most recent query with print\_error.
```
<?php $wpdb->print_error(); ?>
```
Note: If you are running WordPress Multisite, you must define the DIEONDBERROR constant for database errors to display like so:
```
<?php define( 'DIEONDBERROR', true ); ?>
```
You can retrieve information about the columns of the most recent query result with get\_col\_info. This can be useful when a function has returned an OBJECT whose properties you don’t know. The function will output the desired information from the specified column, or an array with information on all columns from the query result if no column is specified.
```
<?php $wpdb->get_col_info('type', offset); ?>
```
**type**
(string) What information you wish to retrieve. May take on any of the following values (list taken from the ezSQL docs). Defaults to name.
* name – column name. Default.
* table – name of the table the column belongs to
* max\_length – maximum length of the column
* not\_null – 1 if the column cannot be NULL
* primary\_key – 1 if the column is a primary key
* unique\_key – 1 if the column is a unique key
* multiple\_key – 1 if the column is a non-unique key
* numeric – 1 if the column is numeric
* blob – 1 if the column is a BLOB
* type – the type of the column
* unsigned – 1 if the column is unsigned
* zerofill – 1 if the column is zero-filled
**offset**
(integer) Specify the column from which to retrieve information (with 0 being the first column). Defaults to -1.
* -1 – Retrieve information from all columns. Output as array. Default.
* Non-negative integer – Retrieve information from specified column (0 being the first).
You can clear the SQL result cache with flush.
```
<?php $wpdb->flush(); ?>
```
This clears $<wpdb>->last\_result, $<wpdb>->last\_query, and $<wpdb>->col\_info.
The tables that WordPress creates by default can be found [here](https://codex.wordpress.org/Database_Description).
* $base\_prefix — The original prefix as defined in wp-config.php. For multi-site: Use if you want to get the prefix without the blog number appended.
* $col\_info — The column information for the most recent query results. See Getting Column Information.
* $insert\_id — ID generated for an AUTO\_INCREMENT column by the most recent INSERT query.
* $last\_error — The most recent error text generated by MySQL.
* $last\_query — The most recent query to have been executed.
* $last\_result — The most recent query results.
* $num\_queries — The number of queries that have been executed.
* $num\_rows — The number of rows returned by the last query.
* $prefix — The assigned WordPress table prefix for the site.
* $queries — You may save all of the queries run on the database and their stop times by setting the SAVEQUERIES constant to TRUE (this constant defaults to FALSE). If SAVEQUERIES is TRUE, your queries will be stored in this variable as an array.
* $show\_errors — Whether or not Error echoing is turned on. Defaults to TRUE.
If you are using Multi-Site, you also have access to the following:
* $blogid — The id of the current site (blog).
* $siteid — The id of the current network (formerly “site”). WordPress currently only supports one network per multi-site install, but that could change in future. See the following for more information: WordPress: difference between site\_id and blog\_id?

* [\_\_construct](wp_site_query/__construct) — Sets up the site query, based on the query vars passed.
* [get\_search\_sql](wp_site_query/get_search_sql) — Used internally to generate an SQL string for searching across multiple columns.
* [get\_site\_ids](wp_site_query/get_site_ids) — Used internally to get a list of site IDs matching the query vars.
* [get\_sites](wp_site_query/get_sites) — Retrieves a list of sites matching the query vars.
* [parse\_order](wp_site_query/parse_order) — Parses an 'order' query variable and cast it to 'ASC' or 'DESC' as necessary.
* [parse\_orderby](wp_site_query/parse_orderby) — Parses and sanitizes 'orderby' keys passed to the site query.
* [parse\_query](wp_site_query/parse_query) — Parses arguments passed to the site query with default query parameters.
* [query](wp_site_query/query) — Sets up the WordPress query for retrieving sites.
* [set\_found\_sites](wp_site_query/set_found_sites) — Populates found\_sites and max\_num\_pages properties for the current query if the limit clause was used.

===============================
Customize Widgets class.
Implements widget management in the Customizer.
* [WP\_Customize\_Manager](wp_customize_manager)
[WP\_Customize\_Widgets](wp_customize_widgets) is WordPress’ class for implementing widget management via the [Theme Customization API](https://developer.wordpress.org/themes/customize-api/ "Theme Customization API") for WordPress 3.9 and newer.
This live preview and management of widgets via the Customizer serves as a secondary option to the traditional widget management workflow already in place.
WordPress instantiates the class via [WP\_Customize\_Manager](wp_customize_manager "Class Reference/WP Customize Manager") and works by adding a new Customizer section for each of the active sidebars visible in the Customizer preview.

*
* @type string|string[] $taxonomy Taxonomy name, or array of taxonomy names, to which results
* should be limited.
* @type int|int[] $object_ids Object ID, or array of object IDs. Results will be
* limited to terms associated with these objects.
* @type string $orderby Field(s) to order terms by. Accepts:
* - Term fields ('name', 'slug', 'term_group', 'term_id', 'id',
* 'description', 'parent', 'term_order'). Unless `$object_ids`
* is not empty, 'term_order' is treated the same as 'term_id'.
* - 'count' to use the number of objects associated with the term.
* - 'include' to match the 'order' of the `$include` param.
* - 'slug__in' to match the 'order' of the `$slug` param.
* - 'meta_value'
* - 'meta_value_num'.
* - The value of `$meta_key`.
* - The array keys of `$meta_query`.
* - 'none' to omit the ORDER BY clause.
* Default 'name'.
* @type string $order Whether to order terms in ascending or descending order.
* Accepts 'ASC' (ascending) or 'DESC' (descending).
* Default 'ASC'.
* @type bool|int $hide_empty Whether to hide terms not assigned to any posts. Accepts
* 1|true or 0|false. Default 1|true.
* @type int[]|string $include Array or comma/space-separated string of term IDs to include.
* Default empty array.
* @type int[]|string $exclude Array or comma/space-separated string of term IDs to exclude.
* If `$include` is non-empty, `$exclude` is ignored.
* Default empty array.
* @type int[]|string $exclude_tree Array or comma/space-separated string of term IDs to exclude
* along with all of their descendant terms. If `$include` is
* non-empty, `$exclude_tree` is ignored. Default empty array.
* @type int|string $number Maximum number of terms to return. Accepts ''|0 (all) or any
* positive number. Default ''|0 (all). Note that `$number` may
* not return accurate results when coupled with `$object_ids`.
* See #41796 for details.
* @type int $offset The number by which to offset the terms query. Default empty.
* @type string $fields Term fields to query for. Accepts:
* - 'all' Returns an array of complete term objects (`WP_Term[]`).
* - 'all_with_object_id' Returns an array of term objects
* with the 'object_id' param (`WP_Term[]`). Works only
* when the `$object_ids` parameter is populated.
* - 'ids' Returns an array of term IDs (`int[]`).
* - 'tt_ids' Returns an array of term taxonomy IDs (`int[]`).
* - 'names' Returns an array of term names (`string[]`).

* keyed by term ID (`int[]`).
* - 'id=>name' Returns an associative array of term names,
* keyed by term ID (`string[]`).
* - 'id=>slug' Returns an associative array of term slugs,
* keyed by term ID (`string[]`).
* Default 'all'.
* @type bool $count Whether to return a term count. If true, will take precedence
* over `$fields`. Default false.
* @type string|string[] $name Name or array of names to return term(s) for.
* Default empty.
* @type string|string[] $slug Slug or array of slugs to return term(s) for.
* Default empty.
* @type int|int[] $term_taxonomy_id Term taxonomy ID, or array of term taxonomy IDs,
* to match when querying terms.
* @type bool $hierarchical Whether to include terms that have non-empty descendants
* (even if `$hide_empty` is set to true). Default true.
* @type string $search Search criteria to match terms. Will be SQL-formatted with
* wildcards before and after. Default empty.
* @type string $name__like Retrieve terms with criteria by which a term is LIKE
* `$name__like`. Default empty.
* @type string $description__like Retrieve terms where the description is LIKE
* `$description__like`. Default empty.
* @type bool $pad_counts Whether to pad the quantity of a term's children in the
* quantity of each term's "count" object variable.
* Default false.
* @type string $get Whether to return terms regardless of ancestry or whether the
* terms are empty. Accepts 'all' or '' (disabled).
* Default ''.
* @type int $child_of Term ID to retrieve child terms of. If multiple taxonomies
* are passed, `$child_of` is ignored. Default 0.
* @type int $parent Parent term ID to retrieve direct-child terms of.
* Default empty.
* @type bool $childless True to limit results to terms that have no children.
* This parameter has no effect on non-hierarchical taxonomies.

* an object cache. Default 'core'.
* @type bool $update_term_meta_cache Whether to prime meta caches for matched terms. Default true.
* @type string|string[] $meta_key Meta key or keys to filter by.
* @type string|string[] $meta_value Meta value or values to filter by.
* @type string $meta_compare MySQL operator used for comparing the meta value.

*
* The request fields value is an associative array with the following keys:
*
* - `url`: Request URL Same as the `$url` parameter to
* {@see Requests::request}
* (string, required)
* - `headers`: Associative array of header fields. Same as the `$headers`

* (array, default: `array()`)
* - `data`: Associative array of data fields or a string. Same as the
* `$data` parameter to {@see Requests::request}
* (array|string, default: `array()`)
* - `type`: HTTP request type (use Requests constants). Same as the `$type`
* parameter to {@see Requests::request}
* (string, default: `Requests::GET`)
* - `cookies`: Associative array of cookie name to value, or cookie jar.
* (array|Requests_Cookie_Jar)
*
* If the `$options` parameter is specified, individual requests will
* inherit options from it. This can be used to use a single hooking system,
* or set all the types to `Requests::POST`, for example.
*
* In addition, the `$options` parameter takes the following global options:
*
* - `complete`: A callback for when a request is complete. Takes two
* parameters, a Requests_Response/Requests_Exception reference, and the
* ID from the request array (Note: this can also be overridden on a
* per-request basis, although that's a little silly)

wordpress class WP_List_Table {} class WP\_List\_Table {}
========================
Base class for displaying a list of items in an ajaxified HTML table.
Note: This class’s access is marked as private. That means it is not intended for use by plugin and theme developers as it is subject to change without warning in any future WordPress release. If you would still like to make use of the class, you should make a copy to use and distribute with your own project, or else use it at your own risk. This class is used to generate the List Tables that populate WordPress’ various admin screens. It has an advantage over previous implementations in that it can be dynamically altered with AJAX and may be hooked in future WordPress releases.
On March 27, 2012, [Andrew Nacin](https://profiles.wordpress.org/nacin) [warned developers](http://wpengineer.com/2426/wp_list_table-a-step-by-step-guide/#comment-9617) that this class was created for private core use only as it may be subject to change in any future WordPress release.
Nevertheless, [the](http://kovshenin.com/2012/wp_list_table-tutorial/#comment-10362) [WP\_List\_Table](wp_list_table) class has become widely used by plugins and WordPress developers as it provides a reliable, consistent, and semantic way to create custom list tables in WordPress. To date, no major changes have occurred in this class or are scheduled to occur, so testing your plugin with beta/RC phases of WordPress development should be more than enough to avoid any major issues.
If you are at all uncomfortable with this risk, a common (and safe) workaround is to **make a copy the [WP\_List\_Table](wp_list_table) class ( `[/wp-admin/includes/class-wp-list-table.php](https://core.trac.wordpress.org/browser/tags/5.5.1/src//wp-admin/includes/class-wp-list-table.php#L0)` ) to use and distribute in your plugins**, instead of using the original core class. This way, if the core class should ever change, your plugins will continue to work as-is.
Developers should use this class at their own risk.
This class is meant to be used as a kind of framework, since any data queries need to be loaded, sorted, and filtered manually. Nevertheless, it is potentially a very powerful tool for developers as it creates WordPress-standard list tables, which makes it very easy to implement advanced features like pagination, actions, bulk actions, and filtering.
To use the [WP\_List\_Table](wp_list_table), you first create a new class that extends the original. Your new class must be instantiated, and the prepare\_items() and display() methods called explicitly on the instance. See the method descriptions below for more details.
The WordPress core loads and returns its classes dynamically by using the [\_get\_list\_table()](../functions/_get_list_table) function, which automatically loads the appropriate extended class and instantiates it. *This is a private function, however, and should not be used by developers.*
Since this class is marked as private, developers should use this only at their own risk as this class is subject to change in future WordPress releases. Any developers using this class are **strongly** encouraged to test their plugins with all WordPress beta/RC releases to maintain compatibility.
Since developers cannot use the [\_get\_list\_table()](../functions/_get_list_table) function directly, the class needs to be extended and instantiated manually, like so…
```
class Example_List_Table extends WP_List_Table {}
$example_lt = new Example_List_Table();
```
The above example won’t be able to output anything meaningful, however, as several methods MUST be specified (as well as your data) in order for [WP\_List\_Table](wp_list_table) to render a useful table.
Please refer source code for the complete lists of methods and properties. Below description may cover some of them.
The following properties are built into the base [WP\_List\_Table](wp_list_table) class. Note that the magic methods \_\_get and \_\_set of [WP\_List\_Table](wp_list_table) will prevent setting other class instance variables in a subclass of [WP\_List\_Table](wp_list_table), please use the recommended variables:
$items This is used to store the raw data you want to display. Generally you will set this property directly in the prepare\_items() method. $\_args Stores various information about the current table (as an array). This generally isn’t manipulated directly. $\_pagination\_args Stores information needed for handling table pagination (as an array). This generally isn’t manipulated directly, but rather used with get\_pagination\_arg( string ) or set\_pagination\_args(array). $screen This can be used to store the current screen, when it’s necessary to keep it consistent with the entire instance. $\_actions Stores cached bulk actions. This generally isn’t manipulated directly. $\_pagination Stores cached pagination output. This generally isn’t manipulated directly. These properties are not built-in, but are expected by several class methods. You must define them manually in your extended class.
$\_column\_headers In core, this property is assigned automatically. Developers **must** manually define it in their prepare\_items() *or* \_\_construct() methods. This property requires a 4-value array : * The first value is an array containing column slugs and titles (see the get\_columns() method).
* The second value is an array containing the values of fields to be hidden.
* The third value is an array of columns that should allow sorting (see the get\_sortable\_columns() method).
* The fourth value is a string defining which column is deemed to be the primary one, displaying the row’s actions (edit, view, etc). The value should match that of one of your column slugs in the first value.
These methods are not included in the base class but can, and should, be defined in your extended class!
column\_default( $item, $column\_name ) This is method that is used to render a column when no other specific method exists for that column. When WP\_List\_Tables attempts to render your columns (within single\_row\_columns()), it first checks for a column-specific method. If none exists, it defaults to *this* method instead. This method accepts two arguments, a single **$item** array and the **$column\_name** (as a slug).
**NOTICE**: As of [WordPress 3.5.1](https://codex.wordpress.org/Version_3.5.1 "Version 3.5.1"), in core $item is passed an Object, not an array. column\_$custom( $item ) Custom columns must be provided by the developer and can be used to handle each type column individually. For example: if a method named *column\_movie\_title()* were provided, it would be used to render any column that had the slug “movie\_title“. This function accepts one argument – a single **$item** array.
**NOTICE**: As of [WordPress 3.5.1](https://wordpress.org/support/wordpress-version/version-3-5-1/ "Version 3.5.1"), in core $item is passed an Object, not an array. * [\_\_call](wp_list_table/__call) — Make private/protected methods readable for backward compatibility.

Core class used as the default shutdown handler for fatal errors.

The custom class should extend this class and can override its methods individually as necessary. The file must return the instance of the class that should be registered.
* [detect\_error](wp_fatal_error_handler/detect_error) — Detects the error causing the crash if it should be handled.
* [display\_default\_error\_template](wp_fatal_error_handler/display_default_error_template) — Displays the default PHP error template.
* [display\_error\_template](wp_fatal_error_handler/display_error_template) — Displays the PHP error template and sends the HTTP status code, typically 500.
* [handle](wp_fatal_error_handler/handle) — Runs the shutdown handler.
* [should\_handle\_error](wp_fatal_error_handler/should_handle_error) — Determines whether we are dealing with an error that WordPress should handle in order to protect the admin backend against WSODs.

wordpress class Requests_Session {} class Requests\_Session {}
==========================
Session handler for persistent requests and default parameters
Allows various options to be set as default values, and merges both the options and URL properties together. A base URL can be set for all requests, with all subrequests resolved from this. Base options can be set (including a shared cookie jar), then overridden for individual requests.
* [\_\_construct](requests_session/__construct) — Create a new session
* [\_\_get](requests_session/__get) — Get a property's value
* [\_\_isset](requests_session/__isset) — Remove a property's value
* [\_\_set](requests_session/__set) — Set a property's value
* [\_\_unset](requests_session/__unset) — Remove a property's value
* [delete](requests_session/delete) — Send a DELETE request
* [get](requests_session/get) — Send a GET request
* [head](requests_session/head) — Send a HEAD request
* [merge\_request](requests_session/merge_request) — Merge a request's data with the default data
* [patch](requests_session/patch) — Send a PATCH request
* [post](requests_session/post) — Send a POST request
* [put](requests_session/put) — Send a PUT request
* [request](requests_session/request) — Main interface for HTTP requests
* [request\_multiple](requests_session/request_multiple) — Send multiple HTTP requests simultaneously

wordpress class WP_User {} class WP\_User {}
=================
Core class used to implement the [WP\_User](wp_user) object.
To instantiate a specific user, you may use the class constructor :
```
<?php $user = new WP_User( $id [, $name [, $blog_id ] ] ); ?>
```
You can also use the `wp_get_current_user` global function to get a `WP_User` object matching the current logged user.
```
<?php
$current_user = wp_get_current_user();
if ( $current_user->has_cap('edit_users') ) {
// do something
}
?>
```
Check if user exists:
```
<?php
$current_user = wp_get_current_user();
if ( $current_user->exists() ) {
// do something
}
?>
```
Check if user has a property:
```
<?php
$current_user = wp_get_current_user();
if ( $current_user->has_prop( 'twitter' ) ) {
// do something
}
?>
```
The `WP_User` constructor allows the following parameters :
* **id** (int) – the user’s id. Leave empty to use login name instead.
* **name** (string) – the user’s login name. Ignored if id is set.
* **blog\_id** (int) – the blog id on a multisite environment. Defaults to the current blog id.
The semantics seem rather fuzzy. If `id` is a `WP_User` or other object, or an array of properties, it seems to clone it without touching the cache. Otherwise if id is a number it seems to try to read it possibly from the cache, or from the database using `->get_data_by()`, which can also update the cache. If `id` is empty it reads by login name.
> *Note*: If called with the `id` or `name` parameter, the constructor queries the `(wp_)users` table. If successful, the additional row data become properties of the object: `user_login`, `user_pass`, `user_nicename`, `user_email`, `user_url`, `user_registered`, `user_activation_key`, `user_status`, `display_name`, `spam` *(multisite only)*, `deleted` *(multisite only)*.

wordpress class WP_Styles {} class WP\_Styles {}
===================
Core class used to register styles.
* [WP\_Dependencies](wp_dependencies)
`WP_Styles` is a class that helps developers interact with a theme. It ensures registered stylesheets are output in the proper order, with dependent stylesheets coming after their dependencies. While more than one instance can be created, typically the global $wp\_styles is used to enqueue stylesheets, which are then output by `wp_print_styles` during the [wp\_head](../hooks/wp_head "Plugin API/Action Reference/wp head") action. `WP_Styles` extends `[WP\_Dependencies](wp_dependencies "Class Reference/WP Dependencies")`.
`WP_Styles` handles both external and embedded stylesheets (though the latter must be associated with one of the former), outputting a <link> or <style> element as appropriate.
For any stylesheet, an additional stylesheet can be loaded for right-to-left text (triggered by setting $wp\_styles->text\_direction to ‘rtl’). The URL for this stylesheet is built by inserting ‘-rtl’ into the URL of the left-to-right stylesheet. Normally, ‘-rtl’ is inserted before the ‘.css’ extension. If ‘suffix’ is set in the stylesheet’s extra data (using `WP_Dependencies::add_data()` or `_WP_Dependency::add_data()`), ‘-rtl’ will be inserted before the suffix and ‘.css’ extension (`"${suffix}.css"`).
When it comes time to output enqueued stylesheets, `WP_Styles` can print them, or accumulate them in instance variables ($print\_html for external and $print\_code for embedded). This behaviour is controlled by the boolean instance variable $do\_concat. If true, output is concatenated to the appropriate instance variable; if false, it’s printed.
Any [unconditional](http://msdn.microsoft.com/en-us/library/ms537512.aspx), non-[alternate](http://www.w3.org/Style/Examples/007/alternatives.en.html) stylesheet in a default directory (as determined by `WP_Styles::in_default_dir()`) isn’t accumulated when $do\_concat is true.
The media for a stylesheet is passed via the $args argument to `[WP\_Dependencies](wp_dependencies "Class Reference/WP Dependencies")::add()`.
Note: Refer source code for the complete list of properties and hooks.
$base\_url The base URL for the site, it gets prepended to the URL for an enqueued sheet in most cases (see $content\_url for an exception). Set to the site URL (as determined by `[site\_url()](../functions/site_url "Function Reference/site url")` or `wp_guess_url()`) by default. $content\_url The URL for the wp-content directory. Set to `WP_CONTENT_URL` by default. If a stylesheet URL begins with the content URL, the base URL isn’t prepended. $default\_version Default value used when a version isn’t specified in a call to [wp\_enqueue\_style()](../functions/wp_enqueue_style) or [wp\_register\_style()](../functions/wp_register_style) . $text\_direction = ‘ltr’ If ‘rtl’, an addtional stylesheet will be loaded, allowing custom styling targeting right-to-left. $do\_concat = false If true, concatenate output to $print\_html and $print\_code member variables rather than printing it. $print\_html = “” holds accumulated HTML (<link> elements and conditional comments). $print\_code = “” holds accumulated embedded style rules. $concat = “” list of item handles that were accumulated, separated by commas. $concat\_version = “” list of item handles & versions that were accumulated. $default\_dirs Path or array of paths. Used by `WP_Styles::in_default_dir()`. Compared directly to $src property of a stylesheet. Note: Refer source code for the complete list of hooks.
* wp\_default\_styles – Invoked when a [WP\_Styles](wp_styles) is created. The instance is passed to action hooks.
* print\_styles\_array – Filters list of stylesheets to be output. Called from `WP_Styles::all_deps()`.
* style\_loader\_src – Filter a stylesheet URL in preparation for output. Happens after $base\_url has been prepended (if warranted).
* style\_loader\_tag – Filter the <link> element for a stylesheet.
* [\_\_construct](wp_styles/__construct) — Constructor.
* [\_css\_href](wp_styles/_css_href) — Generates an enqueued style's fully-qualified URL.
* [add\_inline\_style](wp_styles/add_inline_style) — Adds extra CSS styles to a registered stylesheet.
* [all\_deps](wp_styles/all_deps) — Determines style dependencies.
* [do\_footer\_items](wp_styles/do_footer_items) — Processes items and dependencies for the footer group.
* [do\_item](wp_styles/do_item) — Processes a style dependency.
* [in\_default\_dir](wp_styles/in_default_dir) — Whether a handle's source is in a default directory.
* [print\_inline\_style](wp_styles/print_inline_style) — Prints extra CSS styles of a registered stylesheet.
* [reset](wp_styles/reset) — Resets class properties.

wordpress class WP_Error {} class WP\_Error {}
==================
WordPress Error class.
Container for checking for WordPress errors and error messages. Return [WP\_Error](wp_error) and use [is\_wp\_error()](../functions/is_wp_error) to check if this class is returned. Many core WordPress functions pass this class in the event of an error and if not handled properly will result in code errors.
[WP\_Error](wp_error) is a class that makes error handling within plugins and WordPress itself much easier.
Instances of [WP\_Error](wp_error) store error codes and messages representing one or more errors, and whether or not a variable is an instance of [WP\_Error](wp_error) can be determined using the [is\_wp\_error()](../functions/is_wp_error) function.
Error codes are slugs that are used to identify each error. They are mostly useful when a piece of code can produce several different errors, and you want to handle each of those errors differently.
The error codes used in WordPress are not integers, but strings, with any spaces between words replaced with underscores (example: an\_error\_code). The error codes used in WordPress are usually based on the error message associated with that code.
Please refer source code for the complete lists of properties. Below description may cover some of them.
$errors Array containing the list of errors. $error\_data Array containing the list of data for error codes. * see [is\_wp\_error()](../functions/is_wp_error) for more information on trapping for errors (particularly useful when faced with the dreaded ‘Catchable fatal error: Object of class [WP\_Error](wp_error) could not be converted to string’)
* [\_\_construct](wp_error/__construct) — Initializes the error.
* [add](wp_error/add) — Adds an error or appends an additional message to an existing error.
* [add\_data](wp_error/add_data) — Adds data to an error with the given code.
* [copy\_errors](wp_error/copy_errors) — Copies errors from one WP\_Error instance to another.
* [export\_to](wp_error/export_to) — Exports the errors in this object into the given one.
* [get\_all\_error\_data](wp_error/get_all_error_data) — Retrieves all error data for an error code in the order in which the data was added.
* [get\_error\_code](wp_error/get_error_code) — Retrieves the first error code available.
* [get\_error\_codes](wp_error/get_error_codes) — Retrieves all error codes.
* [get\_error\_data](wp_error/get_error_data) — Retrieves the most recently added error data for an error code.
* [get\_error\_message](wp_error/get_error_message) — Gets a single error message.
* [get\_error\_messages](wp_error/get_error_messages) — Retrieves all error messages, or the error messages for the given error code.
* [has\_errors](wp_error/has_errors) — Verifies if the instance contains errors.
* [merge\_from](wp_error/merge_from) — Merges the errors in the given error object into this one.
* [remove](wp_error/remove) — Removes the specified error.

wordpress class WP_Style_Engine {} class WP\_Style\_Engine {}
==========================
Class [WP\_Style\_Engine](wp_style_engine).
The Style Engine aims to provide a consistent API for rendering styling for blocks across both client-side and server-side applications.
This class is final and should not be extended.
This class is for internal Core usage and is not supposed to be used by extenders (plugins and/or themes).
This is a low-level API that may need to do breaking changes. Please, use wp\_style\_engine\_get\_styles instead.
* [compile\_css](wp_style_engine/compile_css) — Returns compiled CSS from css\_declarations.
* [compile\_stylesheet\_from\_css\_rules](wp_style_engine/compile_stylesheet_from_css_rules) — Returns a compiled stylesheet from stored CSS rules.
* [get\_classnames](wp_style_engine/get_classnames) — Returns classnames, and generates classname(s) from a CSS preset property pattern, e.g., '`var:preset||`'.
* [get\_css\_declarations](wp_style_engine/get_css_declarations) — Returns an array of CSS declarations based on valid block style values.
* [get\_css\_var\_value](wp_style_engine/get_css_var_value) — Util: Generates a CSS var string, e.g., var(--wp--preset--color--background) from a preset string such as `var:preset|space|50`.
* [get\_individual\_property\_css\_declarations](wp_style_engine/get_individual_property_css_declarations) — Style value parser that returns a CSS definition array comprising style properties that have keys representing individual style properties, otherwise known as longhand CSS properties.
* [get\_slug\_from\_preset\_value](wp_style_engine/get_slug_from_preset_value) — Util: Extracts the slug in kebab case from a preset string, e.g., "heavenly-blue" from 'var:preset|color|heavenlyBlue'.

wordpress class WP_Rewrite {} class WP\_Rewrite {}
====================
Core class used to implement a rewrite component API.
The WordPress Rewrite class writes the rewrite module rules to the .htaccess file. It also handles parsing the request to get the correct setup for the WordPress Query class.
The Rewrite along with WP class function as a front controller for WordPress.
You can add rules to trigger your page view and processing using this component. The full functionality of a front controller does not exist, meaning you can’t define how the template files load based on the rewrite rules.
This document assumes familiarity with [Apache](http://httpd.apache.org)‘s [mod\_rewrite](http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html). If you’ve never heard of this before, try reading about [URL Rewriting](https://en.wikipedia.org/wiki/URL_Rewriting). Also see Otto’s explanation of [hierarchy of rewrite rules](http://lists.automattic.com/pipermail/wp-testers/2009-January/011110.html) in the wp-hackers email list.
Please note that these rules are usually called inside the init hook. Furthermore, permalinks will need to be refreshed (you can do this in WP Admin under Settings -> Permalinks) before the rewrite changes will take effect. Requires one-time use of `flush_rules()` to take effect.
[WP\_Rewrite](wp_rewrite) is WordPress’ class for managing the rewrite rules that allow you to use [Pretty Permalinks](https://wordpress.org/support/article/introduction-to-blogging/#pretty-permalinks "Introduction to Blogging") feature. It has several methods that generate the rewrite rules from values in the database. It is used internally when updating the rewrite rules, and also to find the URL of a specific post, Page, category archive, etc.. It’s defined in wp-includes/rewrite.php as a single instance global variable, $wp\_rewrite, is initialised in wp-settings.php.
Try not to access or set the properties directly, instead use the methods to interact with the $wp\_rewrite object. See also [Rewrite API](https://developer.wordpress.org/apis/handbook/rewrite/ "Rewrite API").
$permalink\_structure The permalink structure as in the database. This is what you set on the Permalink Options page, and includes ‘tags’ like %year%, %month% and %post\_id%. $category\_base Anything to be inserted before category archive URLs. Defaults to ‘category/’. $category\_structure Structure for category archive URLs. This is just the $category\_base plus ‘%category%’. $author\_base Anything to be inserted before author archive URLs. Defaults to ‘author/’. $author\_structure Structure for author archive URLs. This is just the $author\_base plus ‘%author%’. $pagination\_base Anything to be inserted before pagination indices. Defaults to ‘page/’. $feeds Supported feeds names (rdf, rss, atom) Use [add\_feed](../functions/add_feed "Rewrite API/add feed") to override or add. $feed\_base Anything to be inserted before feed URLs. Defaults to ‘feed/’. $feed\_structure Structure for feed URLs. This is just the $feed\_base plus ‘%feed%’. $search\_base Anything to be inserted before searches. Defaults to ‘search/’. $search\_structure Structure for search URLs. This is just the $search\_base plus ‘%search%’. $comments\_base Anything to be inserted just before the $feed\_structure to get the latest comments feed. Defaults to ‘comments’. $comments\_feed\_structure The structure for the latest comments feed. This is just $comments\_base plus $feed\_base plus ‘%feed%’. $date\_structure Structure for dated archive URLs. Tries to be ‘%year%/%monthnum%/%day%’, ‘%day%/%monthnum%/%year%’ or ‘%monthnum%/%day%/%year%’, but if none of these are detected in your $permalink\_structure, defaults to ‘%year%/%monthnum%/%day%’. Various functions use this structure to obtain less specific structures: for example, get\_year\_permastruct() simply removes the ‘%monthnum%’ and ‘%day%’ tags from $date\_structure. $page\_structure Structure for Pages. Just ‘%pagename%’. $front Anything up to the start of the first tag in your $permalink\_structure. $root The root of your WordPress install. Prepended to all structures. $matches Used internally when calculating back references for the redirect part of the rewrite rules. $rules The rewrite rules. Set when rewrite\_rules() is called. $non\_wp\_rules Associative array of “rules that don’t redirect to WP’s index.php (and thus shouldn’t be handled by WP at all)” roughly in the form `'Pattern' => 'Substitution'` (see below). $rewritecode An array of all the tags available for the permalink structure. See [Using Permalinks](https://wordpress.org/support/article/using-permalinks/ "Using Permalinks") for a list. $rewritereplace What each tag will be replaced with for the regex part of the rewrite rule. The first element in $rewritereplace is the regex for the first element in $rewritecode, the second corresponds to the second, and so on. $queryreplace What each tag will be replaced with in the rewrite part of the rewrite rule. The same correspondance applies here as with $rewritereplace. As the rewrite rules are a crucial part of your website’s functionality, WordPress allows plugins to hook into the generation process at several points. rewrite\_rules(), specifically, contains nine filters and one hook for really precise control over the rewrite rules process. Here’s what you can filter in rewrite\_rules():
* [post\_rewrite\_rules](../hooks/post_rewrite_rules "Plugin API/Filter Reference/post rewrite rules") – Used to filter the rewrite rules generated for permalink URLs.
* [date\_rewrite\_rules](../hooks/date_rewrite_rules "Plugin API/Filter Reference/date rewrite rules") – Used to filter the rewrite rules generated for dated archive URLs.
* [{$permastruct}\_rewrite\_rules](../hooks/permastructname_rewrite_rules "Plugin API/Filter Reference/$permastruct rewrite rules") – Can be used to filter permastructs like ‘category’ or other taxonomies.
* [search\_rewrite\_rules](../hooks/search_rewrite_rules "Plugin API/Filter Reference/search rewrite rules") – Used to filter the rewrite rules generated for search URLs.
* [comments\_rewrite\_rules](../hooks/comments_rewrite_rules "Plugin API/Filter Reference/comments rewrite rules") – Used to filter the rewrite rules generated for the latest comment feed URLs.
* [author\_rewrite\_rules](../hooks/author_rewrite_rules "Plugin API/Filter Reference/author rewrite rules") – Used to filter the rewrite rules generated for author archive URLs.
* [page\_rewrite\_rules](../hooks/page_rewrite_rules "Plugin API/Filter Reference/page rewrite rules") – Used to filter the rewrite rules generated for your Pages.
* [root\_rewrite\_rules](../hooks/root_rewrite_rules "Plugin API/Filter Reference/root rewrite rules") – Used to filter the rewrite rules generated for the root of your weblog.
* [rewrite\_rules\_array](../hooks/rewrite_rules_array "Plugin API/Filter Reference/rewrite rules array") – Use to filter *all* the rewrite rules at once.
* [generate\_rewrite\_rules](../hooks/generate_rewrite_rules "Plugin API/Action Reference/generate rewrite rules") – This action hook runs **after** all the rules have been created. If your function takes a parameter, it will be passed a [reference](http://www.php.net/manual/en/language.references.php) to the entire $wp\_rewrite object.
mod\_rewrite\_rules() is the function that takes the array generated by rewrite\_rules() and actually turns it into a set of rewrite rules for the .htaccess file. This function also has a filter, mod\_rewrite\_rules, which will pass functions the string of all the rules to be written out to .htaccess, including the <IfModule> surrounding section. (Note: you may also see plugins using the rewrite\_rules hook, but this is deprecated).

*
* The content attribute's value (i.e. the description to get) can have HTML in it and be well-formed as
* it's a string to the browser. Imagine what happens when attempting to match for the name=description
* first. Hmm, if a > or /> symbol is in the content attribute's value, then it terminates the match
* as the element's closing symbol. But wait, it's in the content attribute and is not the end of the
* element. This is a limitation of using regex. It can't determine "wait a minute this is inside of quotation".
* If this happens, what gets matched is not the entire element or all of the content.
*
* Why not search for the name=description and then content="(.*)"?
* The attribute order could be opposite. Plus, additional attributes may exist including being between
* the name and content attributes.
*
* Why not lookahead?
* Lookahead is not constrained to stay within the element. The first <meta it finds may not include
* the name or content, but rather could be from a different element downstream.
