How can I make my custom shortcode work in a Custom HTML Widget?
I created a plugin and tried to use its shortcode in a Custom HTML Widget, but for some reason it's outputting `[my_shortcode_name]` instead of executing the shortcode.
The shortcode works fine if I place it on the page or in a Text Widget.
How can I make it work in a Custom HTML Widget? | I was able to make it work by adding these two lines to my theme's `functions.php` file:
add_filter( 'widget_text', 'shortcode_unautop');
add_filter( 'widget_text', 'do_shortcode');
The Custom HTML Widget now correctly executes the shortcode function and outputs the result. | stackexchange-wordpress | {

How can I show a custom WordPress menu anywhere I want on my website?
I went into Appearances > Menus and created my own menu called "default menu." Then I tried to include it in my WordPress theme, but was unsuccessful. I am trying to include it just before the footer.
When I tried with this code:
<?php wp_nav_menu('theme_location=header-menu&container=false&menu_id='); ?>
it just gave me a list of all the pages I've created.
So then I tried with:
<?php echo do_shortcode('[listmenu menu="default menu"]'); ?>
and then it just echoed what was in the PHP tag.
Please tell me what I should be doing differently. Thank you. | `wp_nav_menu()` is the correct function to display a menu.
Is the default menu assigned to the location you've specified and if so, are there any items assigned to that menu?
Menus without any items assign will display pages by default. You could try adding the `menu` param with a value of the name of your default menu. | stackexchange-wordpress | {

Restricting users to a specific front end page
I am looking for a way to restrict users of a certain role to only be able to access one page on my wordpress site. When a user of the role logs in they should be redirected to the page and they should not be able to access any other pages. I have tried multiple plugins that can restrict pages to users, but I have not found one that can restrict users to pages. Does this functionality exist within Wordpress and how would I implement it if it does? | You'd have to add a function during the `init` action of WP. There you'll get the `current user` and check whether they have a specific `role` assigned to them and `redirect` to the page when they do.
add_action('init', function () {
$user = wp_get_current_user();
$role = 'your role';
if (in_array($role, $user->roles)) {
wp_redirect('url');
}
});

Save button is not working on custom widget

remove string: 'custom content...' from every page
I'm not quite sure how this came about, but every page on my site has the text 'custom content...' appended to the end of the body. The string appears within `<p>` tags on the frontend.

Shortcode from a function not working
I am trying to create a shortcode from a custom function in WP but it seems like I'm doing something wrong.
I have a function in child's theme function.php and add_shortcode code:
function uniquetestfunction() {

}
add_shortcode(‘uniqueshortcodename’,’uniquetestfunction’);

Inserting post content into pages when using custom taxonomies

$post_id_927 = get_post($my_id, ARRAY_A);
$title = $post_id_927['post_content'];
?>
</div>
</div>
<?php
}
?>

Stop WooCommerce from updating user/user meta after checkout
Customers have billing/shipping addresses saved to their account and when they checkout they are presented with the billing/shipping address fields. If they update them in the checkout and confirm their order, this also updates their addresses on their account. I understand this is the expected behaviour but not what our site requires.
I want to still show the address fields on the checkout but don't want it to update their account once it is being processed, but I also need the addresses they enter during checkout to be attached to the order meta, so the addresses on the order/order meta match those that they entered during checkout.
Is this possible? I've tried looking for hooks or how to programatically approach this but all I can find is how to add additional meta fields to an order which is not what I want. | To avoid user registration data to be updated each time an order is placed use the following:

correct validate and sql query

} | What you're doing is safe.
However, some notes:
1. See the `WP_User_Query` class in the Codex. This is the, "official," way to do something like this, although you'll get an integer-indexed array of `WP_User` objects. Instead of the `ARRAY_A` that you've specified.
2. You probably don't want `_my_table`, unless your table is called something like `wp__my_table` (note the double underscore after `wp`). The prefix returned from `$wpdb->prefix` includes the underscore that many installations use after the prefix.
3. The `trim()` call after `sanitize_user()` is superfluous. It doesn't hurt anything but it's also a waste of compute cycles.
4. You may be able to write this in one line: `$results = $wpdb->get_results($wpdb->prepare("select * from {$wpdb->prefix}my_table where name = %s", sanitize_user($_POST['name'])), ARRAY_A);` This may be better or worse for you. | stackexchange-wordpress | {

What is the criteria for pluggable functions?
Why are certain functions pluggable (overrideable) in WordPress core and others not? (I note on the Codex page regarding Pluggable Functions no more are to be added in favour of filter usage.)
But theoretically, would there be any security implications or other concerns for having them all pluggable - or is it simply so less pluggable code becomes incompatible with core updates? | Pluggable functions are less elastic than filters/actions.
You can have only one pluggable function “active” - so only one plugin can override the core function. And you don’t have much control over which plugin will it be (WP will use the pluggable function that gets defined first).
So it won’t be very useful if all actions were replaced by pluggable functions.
On the other hand, there are some cases that using pluggable functions may have some sense. wp_mail is great example, I guess. If you want to change the way the emails are sent - you can. But you still want only one such function (otherwise, if you install two plugins that are changing it, you can end with multiple emails sent for every wp_email call).

Wordpress plugins for database queries
I have a handful of custom database commands that my admin users need to execute on an adhoc basis - it's some business logic that was unavailable in a normal plugin. The commands are all procedures that either execute successfully, or return a record set.
I want to be able to make these commands available through the Wordpress admin interface, ideally saving each query with a friendly name (eg Process1 - start of day) so that it is easier to execute but I haven't been able to find a solution. The admin users are slightly horrified by the likes of PHPMyAdmin for Wordpress, or even using SSH to get to a Bash menu script which executes database commands when options are selected. | I don't know of a plugin that allows you to do this out of the box, but as you are (/seem to be) comfortable with database manipulation, I've outlined below how you can achieve what you want using custom coding.
You can run custom queries using the `wpdb`-class. There are a few posts on WPSE/SO that treat this. Once you've set those up, you can run them on, for example, a custom admin page (a new page in the Wordpress Dashboard). There are various tutorials available online (such as this one) that show how that can be done. | stackexchange-wordpress | {

How to keep close a sub-menu under homepage?
I am facing an issue in the Avada vertical menu when the homepage is opened. Please note that all "Home", "Company profile" and "Servizi" link to the same page (the homepage).
The sub-menu under "Servizi" is already opened while I would prefer it was closed by default, and that it could be opened simply by hovering "servizi", as it works properly when you try hovering "Servizi" from both "Clienti" and "Contatti".
I am pretty sure there is an option in Avada/WP to do that, or otherwise by adding some JS code, but I really have no idea how to do it! | To do that, you have to set `hidden` attribute to the sub menu.
**CSS**
#wrapper .fusion-vertical-menu-widget.left .menu .sub-menu {
display: none;
}
to toggle display on the menu on hover over servizi, you can add jQuery hover to the menu item.
**jQuery**
var subMenu = jQuery("#wrapper .fusion-vertical-menu-widget.left .menu .sub-menu");
jQuery("#menu-item-12049").hover(function(){
subMenu.show();
}, function(){
subMenu.hide();
});
**Note:** You should change the class values to more appropriate values, these are just extracted from what I saw, but probably a good idea to get better css selectors | stackexchange-wordpress | {

Unit Test in Wordpress
I work in wordpress with a lot of classes that use wordpress functions and I'd like make unit tests for them. The problem I found is that phpunit doesn't recognize wordpress functions and the tests don't work.

Using this process rather than rolling your own allows you to leverage the boostrapping (and other customization) specific for WordPress.
From the Codex:
> When `phpunit` is invoked, the test suite runs a script that sets up a default installation of WordPress, with a configuration similar to what you get with the GUI install. Before any tests are run, the following steps take place:

> * WordPress is bootstrapped (by including `wp-settings.php`). This means that all tests run after the entire WP bootstrap (through `wp_loaded`).

Do I need normalize.css when developing my own Wordpress-theme?
I'm developing my own Wordpress theme and I'm trying to make it as light as possible. I started from the Underscores starter theme, but they use normalize.css to reset the styles.
Is it necessary to include it in my theme or is there a better method? | Web standards are pretty good these days and IMO I don't think things like normalize are nearly as necessary as years ago.
I would recommend having a look through the CSS file and deciding for yourself.

Quick note: You can use caniuse.com to look up specific styles or tags you might have questions about.
For Example, normalize includes this CSS...
main {
display: block;
}

How to get "Additional CSS Class" for ACF Gutenberg block
I have registered a custom block with ACFs `acf_register_block`. I have set a `render_callback` to load a php template but would like to access any extra CSS classes which the user may have set in the admin.
 or would I need to raise a question on the ACF support forums? | _Note that I don't have ACF PRO 5.8 which comes with the Block features, but I hope this answer helps._
If you look at the example here, you can retrieve the additional/custom CSS classes using `props.attributes.className`; i.e. the classes are saved as an _attribute_ named `className`.
So with that in mind and based on `acf_register_block()` (which as of writing, it redirects to `acf_register_block_type()`), your `render_callback` function would receive a `$block` array (the block settings and attributes) as the first argument, and therefore you should be able to retrieve the additional CSS class(es) via `$block['className']` as shown here -- see the example under " _Registering a block with callback_ ". | stackexchange-wordpress | {

wp post create --post_title="test" --post_content="[gallery ids='$(wp media import --porcelain)']"
Thanks ! | There is just `[gallery]` to display images BUT you can specify in which size the image(s) will be displayed. By default it's `size='thumbnail'`. Simply set it to `size='full'` to just get one full-sized image:
$ wp post create --post_title="Foobar" --post_content="[gallery ids='$(wp media import --porcelain)' size='full']"

How to include custom PHP file both in header and footer files
I have created a custom file that both the header and the footer needs to render certain content.
If I only do `include($_SERVER['DOCUMENT_ROOT'] . '/wp-content/themes/myTheme/myCustomFile.php');` in the `header.php` file it works as expected BUT only in the header.
Likewise with the footer, If I only do `include($_SERVER['DOCUMENT_ROOT'] . '/wp-content/themes/myTheme/myCustomFile.php');` in the `footer.php` file it works as expected BUT only in the footer.
The moment I have the include on both files, the page renders up until the footer starts and then stops rendering.
How can I include this file so it can be accessed from anywhere in the theme?
I also tried the other import methods in PHP - require, require_once, and include_once – same deal.
Thank you in advance. | You wrote that you have a function definition in file that you include. I suspect that the reason is the function redeclaration error.
You should move the function definition from `myCustomFile.php` to `functions.php`.
You can also before each function definition in `myCustomFile.php` check whether there is already a function of the same name.
if ( ! function_exists('you_function_name') ) {
function you_function_name() {

How to exclude children categories of parent category
I want to list only certain categories and exclude a particular parent and all its children. The reason is so that if a new child category is added, it won't show up by default. With wp_list_categories you also get an active class but with get_categories you don't. I would also like to somehow get an active class from it if possible.
I tried this:
$categories = get_categories(array(
'exclude' => array(40)
));
But it still shows the children of category with ID 40.
The below code hides all the children but is a pain to try and style it whereas if I run my own loop with get_categories I can style the output much easier.
<?php wp_list_categories( array(
'orderby' => 'name',
'show_count' => false,
'exclude' => array( 40 )
) ); ?> | $categories = get_categories( array(
'exclude_tree' => array(40)
));
In both `get_categories()` and `wp_list_categories()` you can use the `exclude_tree` parameter instead of `exclude`.
> * **exclude_tree**
> (array|string) Array or comma/space-separated string of term ids to exclude along with all of their descendant terms. If _$include_ is non-empty, $exclude_tree is ignored.

Extract url of every image in library?
I'd like to make a PHP script to output the full-size URL of every image on the WordPress library. How can i make a foreach of all images in the site? | First you have to get all attachments. You can use `get_posts` function for this:
$attachments = get_posts( array(
'post_type' => 'attachment',
'posts_per_page' => -1,
) );
Then you have to loop through them and get their urls using `wp_get_attachment_url`:
foreach ( $attachments as $att ) {
echo wp_get_attachment_url( $att->ID );

Query WooCommerce orders where meta data does not exist
I'm trying to fetch all my WooCommerce orders where some additional metadata is equal to not empty.
$orders = wc_get_orders( array(
'orderby' => 'date',
'order' => 'DESC',
'meta_query' => array(
array(
'key' => 'var_rate',
'compare' => 'NOT EXISTS',
)
)
));
So if the `var_rate` is empty or doesn't exist then do not return that record. At the moment all orders are returned using those arguments.
Example of empty record -
object(WC_Meta_Data)#2344 (2) {
["current_data":protected]=>
array(3) {
["id"]=>
int(6471)
["key"]=>
string(15) "var_rate"
["value"]=>
NULL
}
["data":protected]=>
array(3) {
["id"]=>
int(6471)
["key"]=>
string(15) "var_rate"
["value"]=>
NULL
}
} | The `meta_query` argument _(that you can use in a`WP_Query`)_ is not enabled by default when using a `WC_Order_Query` through `wc_get_orders()` WooCommerce function.
But for you can use the undocumented Custom Field Parameters _(just like in a`WP_Query`)_:
* `meta_key`
* `meta_value`
* `meta_value_num`
* `meta_compare`
So in your case you can use the following instead:
$orders = wc_get_orders( array(
'limit' => -1, // Query all orders
'orderby' => 'date',
'order' => 'DESC',
'meta_key' => 'var_rate', // The postmeta key field
'meta_compare' => 'NOT EXISTS', // The comparison argument
));

wp_insert_post with data from graph api inside a plugin

the correct order of manual install WP and SSL on server
I am wundering what the correct order of these next things is when you want to manually install Wordpress and have SSL installed on your server and website. Is this the correct order to do that in?
1. Install SSL certificate for the site on the server
2. Manually install WordPress
3. Go to your website and do all the WP settings for SSL
And what if you don't do it in this order? | There's not a correct order. Either way will work and results in a WordPress install that is secured with SSL. What makes sense in a situation, depends on the setup and workflow.
If you can plan ahead, it's optimal to set up the SSL on your server first. Because doing so, you don't have to go back through WordPress, and change settings and the database. In short, you're saving yourself work and avoid potential sources of errors. | stackexchange-wordpress | {

Proper way to use apply_filters() with class functions?
I want to allow my user to override a function. It's a plugin. I believe that apply_filters() can be used for this. this can be overridden by add_filter().
I am confused about how to use it. Say if i have a class like this
class Example{
public function hello(){
$title = the_title_attribute();
return $title;
}
}
What change should I make to allow that $title to be modified? where to place the apply filter? Thanks | It depends on you where you want to call `apply_filters()`.
It can be right when you defined the `$title`:
$title = apply_filters( 'my_hook', the_title_attribute( 'echo=0' ) ); // set echo to false
return $title;
Or in the `return` call:
$title = the_title_attribute( 'echo=0' ); // set echo to false
return apply_filters( 'my_hook', $title );
Then one can hook to the filter like so:
add_filter( 'my_hook', 'some_function' );
PS: As @birgire pointed, `the_title_attribute()` will echo output, unless the `echo` argument is set to `false`. So be sure to use the function with the proper parameters. | stackexchange-wordpress | {

Rewrite rules in multisite
I've been trying to set up different rewrite rules on my multisite installation, but as of now, nothing is working. Even the simple
`add_rewrite_rule('^welcome$', 'index.php?p=1', 'top');`

Is there anything to do when setting up rewrite rules using the Rewrite API that needs to be done that isn't explicitity defined in the codex?
This problem led me to wonder: are rewrite rules written using the API supposed to be written in .htaccess or not?
Thank you in advance.
PS. If I'm duplicating, I am sorry, but I haven't been able to find a well written answer yet. | Found the answers:
1. There is nothing to do when using the Rewrite API that isn't written in the Codex.
2. Rules written using `add_rewrite_rule` are not added to `.htaccess`. WP adds them to its database under `rewrite_rules` in the `_options` table.
It's important not to forget to:
* Filter the rewritten permalinks; call the functions on the `post_type_link` hook and/or the `term_link` hook depending on the situation.
* Remove default rules to avoid conflict and call the function/s on the `rewrite_rules_array` hook.
* Flush and rewrite the rules using `flush_rewrite_rules();` on plugin activation and/or deactivation. | stackexchange-wordpress | {

Adding query string to multiple page urls in a Wordpress function

exit;
}
}
add_filter( 'page_link', 'nocfcache_query_string', 10, 2 ); | In your second code you use undefined `$post` variable.

Advice on redirect to lock site from unauthorized users
Looking for some advice on the below function. I have a web app type site built in WP. There is nothing on the site relevant to non-users, apart from the login form on the homepage. I've got some membership plugins that lock content, but as an added layer of security I was thinking of adding the following:
function lock_non_users_to_front() {
if( !is_user_logged_in() && !is_front_page() ) {
wp_redirect( home_url() );
}
}
add_action( 'template_redirect', 'lock_non_users_to_front' );
Essentially, if anyone tries to access a url that isn't the homepage, and they aren't logged in, it'll just kick them back to the homepage.
Any thoughts/improvements? | The comment by 'warm_tape' is correct. Use home_url(), then put a die() after the wp_redirect to ensure that the accessed page will 'die' and not interfere with your main page. | stackexchange-wordpress | {

Load template file without a post type

$custom_link = rtrim($custom_link, '/');
$custom_link .= '?' . get_the_ID(); ?>
<a href="<?php echo $custom_link; ?>">
// This link to a custom template file
<?php } ?> | You could setup a custom rewrite rule using add_rewrite_rule and send these requests to a custom page.
Your URL structure could be `/index-page/single-event-slug` The rule would point all of the single events to a separate page where you can then set your template `events-single.php`.
Another option is to pass the events in as a query `/index-page?event=single-event-slug` or `/index-page?event=123`. You'd need to register this parameter with add_query_arg and then change your index template to use the event template via the template_include hook. | stackexchange-wordpress | {

Don't replace "|" with Empty String ("") when generating slugs from title
I work for an architecture company and our project names mostly go like this: `house|something`, `bridge|somewhere`, `building|whatever`.
Now, when I want to add a new project named like that, WordPress automatically converts it to `housesomething`, `bridgesomewhere` and puts that as the slug. I'd much prefer to keep some kind of separator, e.g. `house-something`, `bridge-somewhere` instead.
So, how to make WordPress convert `|` to `-` and not `Empty String` (`""`)? I'm obviously tired of doing that manually all the time.
It seems to me that it's very simple to do. It takes just a simple search and replace kind of thing if one knows where to look (in the WP core or wherever), but I haven't the slightest idea where to look, or what code to execute. | When WordPress inserts a post, it runs the title through a filter called `sanitize_title` to get the slug. By default there is a function called `santize_title_with_dashes` attached to this filter with priority 10. This function simply strips out the `|`. If it is surrounded by spaces those spaces will be converted to hyphens.
So your task is to run a filter on the same hook before (say, priority 9) the default one and replace the `|` with `-` before it gets stripped away. Like this:
add_filter( 'sanitize_title', function ( $title ) {
return str_replace( '|', '-', $title );

How safe is current_user_can()?
I'm saving sensitive data via JSON ajax request, it is not sanitized, literally anything can be passed.

So I do:
function received_ajax_request() {

return;
}
save_to_database( $_POST['something']) );
}
My question is how safe it is? Do I need to check for anything else besides `current_user_can`?
For example, I saw some other plugins check also for nonce, but when rest API is used - nonces are generally not used. | `current_user_can` checks whether current user has a specific capability. And only that...
**It won’t protect you from XSS attacks** \- so it would be a good idea to check some _nonces_ too - this way you can be certain that user wants to perform given action.
_Let’s say there’s a link to delete a post. Of course you will check if user can delete posts. But what if a user is logged in and I make him click the link? He doesn’t have to know - it can be a shortened link or an image._
**It also won’t check if the current user is owner of given object.**
_Let’s day I’m a customer in shop. Of course I can add comments to orders. But only for my orders._
So you should always check full access rights and not only roles and capabilities.
**And of course it won’t make the action safe.** So you still have to sanitize, and escape, and so on... | stackexchange-wordpress | {

Where in code to replace content before display of page?

$content = str_replace(...);

I'm using rtMedia and Youzer. Can Shortcodes be used to display a video gallery?

$profile_id = bp_displayed_user_id(); // not sure if this is the right function

How to create a post template with two sidebars

Why should I escape translatable strings? and how shall i do that?
Is it really need to escape translatable strings?
`, `esc_attr__()`, `esc_html_e()`, and `esc_attr_e()`. These functions are essentially just `esc_html()` and `esc_attr()` combined with the `__()` or `_e()` translation functions.
The thing you need to be aware of is that escaping should happen as late as possible. Ideally the last thing that happens before output. In your screenshot you appear to be just defining strings for later use. In that case you wouldn't use `esc_html__()` at this point. Instead you'd just use `__()` and then use `esc_html()` whenever you actually output the string.
