Archive page for Wordpress Custom Post Type doesn't show pagination from paginate_links()
I have a custom post type with `courses-events` as the slug.
In functions.php, I have:
add_action( 'pre_get_posts', 'custom_archive_items' );
function custom_archive_items( $query ) {
if ($query->is_main_query() && !is_admin() && is_post_type_archive( 'courses-events')) {
$query->set( 'posts_per_page', '1' );
}
}
I know the above is firing for my archive page if I dump $query in the condition, it is visible.
On archive-courses-events.php I have simply:
if ( have_posts() ) :
while(have_posts()) : the_post();
<!-- my output -->
endwhile;
echo paginate_links();
endif;
I have 2 posts and as `posts_per_page` is set to 1, but 2 posts appear and I do not see pagination.
I don't understand why this isn't working as everything I've read says that this is the minimum necessary for this to work? | Answered in a comment:
try first with using a priority of 11 or greater, e.g.

Gutenberg getBlockIndex in save() function
In my block's `edit()` function i'm getting the index of each inner block:
// a block used in innerblocks
edit( { attributes, setAttributes, clientId } ) {
let blockIndex = wp.data.select( 'core/editor' ).getBlockIndex( clientId );
...
This works fine. However i tried the same in `save()` but I get index `-1` for each block. How can I make `getBlockIndex()` work in `save()`?
I need to add index number to class names of inner blocks in HTML. | You cannot use `wp.select` in your save component, a save component can _only_ use the block attributes. If you generate markup from using data from other sources then it will fail block validation.
If you want data such as the index of the block, you need to store it in the attributes in the edit component, or render the block in PHP.
The same goes for other "effects", you should not do these things in a save component:
* use state
* make HTTP requests
* retrieve data that didn't come from block attributes
* interactive components
* query the data store
* react hooks e.g `useEffect` or `useCallback`
* prompt the user for data
* extract data from DOM nodes or global variables
The job of a save component is to take the blocks attributes and turn them into static HTML that gets saved in the database. Any interactivity or effects that do work need to go in the edit component or elsewhere, and their results stored in attributes. | stackexchange-wordpress | {

Puzzled at HTTP/2 301 response header
I am running `curl -I with the ` part prepended explicitly, and I am noticing that the response header is about an HTTP/2 301 redirect on the very same URL. Shouldn't that be a 200 instead?
I've triple-checked that the .htaccess does not contain any `RewriteEngine`, `RewriteCond`, or `RewriteRule` lines, and I've even replaced the .htaccess file with the default wordpress .htaccess but that doesn't make any difference whatsoever. I really don't know where this 301 is declared. On the browser a response of 200 can be seen in the Network tab of DevTools'.
I was trying to troubleshoot the page itself which is very slow to load on the browser, and I only discovered said output after trying to check with `curl -I` if HTTP/2 was actually used to serve it. Is this normal? Should I look elsewhere to troubleshoot the slow page load, or is this unusual and should be further investigated? If so, where should I look? | It might be that WordPress is just redirecting to the version with trailing slash.
* `/cart` => `/cart/`
* `/shop` => `/shop/`
I'm having trouble, finding a good canonical source why WP is doing this. The fact is, that most web frameworks (I worked with) will force trailing slashes on their routes (that are not directed at files).

Revision featured image
In WP revision i can not see if i upload featured image and update post. WP revision save just content, heading and excerpt. I have problem with some employs, they said that uploaded image and we do not have that in Database. How can i see in revision or in database if someone upload image on post and update post? | The featured image is saved as postmeta, and by default, postmeta is not stored in revisions. This means that if anyone removes the featured image and saves (updates) their post, that postmeta is removed and not associated to the post anywhere.
If you need to modify this behavior for the future, you can programmatically enable saving postmeta to revisions, though since it's not Core behavior it requires a fair bit of logic.
However, you may be facing some user confusion: is it possible for your users to insert an image within the post content? That is something you can check in the database - as long as you're not using a page builder plugin or anything that saves main content somewhere besides `post_content`. You can check each revision's `post_content` column in the database and see whether any images are there within the content. If so, you could make note of which image the user used, then go into the actual Editor and assign that same image as the featured image for their post. | stackexchange-wordpress | {

Problem with links once in portfolio item

Portfolio item link: < (permalink), once here if I want to go back to my homepage using the same menu, the link is wrong: <
correct one would be: <
Why Is this happening and how can I fix it?
Thanks! | You should check your `Appearance > Menus` Select activated Menu & check its links by clicking on the name tab, you are probably using `#Home` link instead of using a full url of that specific page.
Example:
Home Url should be: `
You might be using: `#Home`
**Update:** If your website has more than one page/s than you should create separate navigation menus.
Separate menu for homepage & Separate menu for other page/s this way you can avoid css style conflicts. You should have an option to use separate menu for specific Page.

Content-Security-Policy blocks Wordpress check boxes from being activated
I have a Content-Security-Policy for my Wordpress Website (LAMP-Server):
`set Content-Security-Policy "base-uri 'self'; default-src 'self'; font-src 'self' data: frame-src img-src 'self' script-src 'self' 'unsafe-inline' ; style-src 'self' 'unsafe-inline' object-src 'self'; form-action 'self'; frame-ancestors 'self';"`
This CSP prevents me from activating any check box in Wordpress (either the check box that remembers my login or the check boxes that let me select which theme to update) (Tested with Firefox in Linux and Chrome on Android).
Without CSP everything works as expected.

Changing siteurl in the database not working
I'm trying to change siteurl and home in the database, but whenever I try to change after 5 seconds they automatically change back to the previous url.
Is it related to the server? | WordPress has a number of standard methods to change or override these url options:
* **using update_option()** function in functions.php or anywhere else in the code, this way: `update_option( 'siteurl', ' );`
`update_option( 'home', ' );`
This is most likely your case because update_option() edits db entries at runtime.
In this case, just remove or comment out these lines where you find them.
* using define();
`define( 'WP_HOME', ' );`
`define( 'WP_SITEURL', ' );`
This only overrides the setting but does not change the entries in the database.
If your url changes in the address bar, but does not change in the database, this may happen due to WordPress caching. Try one of these:
* edit wp-config.php and add **define('ENABLE_CACHE', FALSE);**
* add a query string with an argument to clear cache, i.e. <
* if you use CloudFlare or other caching service, clear cache for this url | stackexchange-wordpress | {

ACF: How to query for a given value count of an array like field? (e.g.: How many rows has a `flexible_content` field?)
How can I write a WordPress meta query that gives me an array of users/posts that have a given amount of entries in a custom field that stores multiple values?
Something like SQL `COUNT()`, but for the number of entries in an ACF array field.
When writing a `WP_Meta_Query` and comparing with `>`, `>=`, etc. this doesn't seem to work for me, perhaps because the data is stored serialized.
So, basically, how can I perform a simple selection of records with a specific count inside their custom field value. | **This isn't possible using`WP_Query`, you can't query the insides of structured data stored in a single post meta value.**
At best you can use regular expressions, or do math/boolean comparisons, you can even do `LIKE` comparisons, but these are all string operations.
If you need to query structured data such as objects or arrays, then the data needs breaking apart into multiple separate post meta values.
At the end of the day, post meta values are just strings of text as far as the database is concerned. You can cast them to a different basic data type such as a date or number, but that's it. | stackexchange-wordpress | {

homepage redirects to login page when user session expires
**WordPress 5.9** Users trying to access the homepage when the `session expires`, are sent to `re-authenticate`.
The behavior seems weird since it only applies to the **homepage**. Users with expired sessions can access all other pages without being asked to re-authenticate.
Why is the behavior inconsistent, and how can users with expired sessions not be redirected to re-authenticate? | If you looked at your plugins one by one and none of them causes the problem, look at your template files that display your home page – could be `index.php, home.php, content.php, content-{slug/id}.php or page-templates/...`, depending on your theme and settings.
Look for
if (!is_user_logged_in()) {
auth_redirect();
}

When there are two identical entries in a .po file, how does the translation mechanism determine which one to use?

Saving plugin's settings in 1 field in json format
This is a question about performance. I've used the Wordpress Settings API in order to register fields and for a plugin that has 30+ fields that can cause a huge amounts of lines of code, in addition, sometimes the plugin has to use `get_option()` a few times to know if it can show specific data on a specific admin page, this causes more database calls.
Instead, wouldn't it be better to save all options in JSON format in 1 field in the options table? Once the admin page loads you just use `get_option('prefix_my_settings')` which will then retrieve a json of all the plugin settings? Then all of the plugin settings are stored in 1 location and uses only 1 database request for each page load.
What are the downsides for using such method and is there a character limit for an option field? | There's always a character limit, but `option_value` is LONGTEXT so unless you anticipate more than 4GB of data you should be fine.
I'd suggest json is unnecessary - you can save a PHP array as the value and it will be serialized/deserialized automatically.
That said, as Tom points out, this is really micro-optimising, and won't really impact performance either way in the real world. If you want to keep your settings together for organizational/clarity reasons though, go ahead. | stackexchange-wordpress | {

Considering this url does NOT point to any content, how can I specify which template to use? I can echo out the `get_post_type()` and it shows `'explore'` as the post type, but I'm seeing that from the `index.php` template.
I tried adding a `page-explore.php` but that didn't work. There doesn't seem to be a `index-[custom-type].php`

Is there a hook for nav menu item links to add custom css programatically?
I know there is this **nav_menu_css_class** hook to add a custom class to the list items in the nav, but is there a similar hook to add a custom class to all link items in the nav? I want all my links in the nav to have this class:
<a class="nav-link" href="#whatever">Sample page</a> | Yes, there is, and the hook is `nav_menu_link_attributes`:
> `apply_filters( 'nav_menu_link_attributes', array $atts, WP_Post $item, stdClass $args, int $depth )`
>
> Filters the HTML attributes applied to a menu item’s anchor element.
For example, this adds the `nav-link` class to the `<a>` tag only if the theme location (`$args->theme_location`) is exactly `my-location`:
add_filter( 'nav_menu_link_attributes', 'my_nav_menu_link_attributes', 10, 3 );
function my_nav_menu_link_attributes( $atts, $item, $args ) {
if ( 'my-location' === $args->theme_location ) {
// Get existing classes, if any.
$class = $atts['class'] ?? '';
// Now add your custom class(es).

Is it necessary to sanitize plugin options?
I've always known that it's good practice to sanitize GET and POST data. I usually do this globally in my functions file with code like this:
$_POST = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);
$_GET = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING);
With plugins that have a Settings screen, using the recommended code for plugins according to the plugin API, is it necessary to sanitize user inputs on the plugin's Settings page, like checkboxes, text fields, etc?
Or does the Plugin API take care of POST/GET sanitization on plugin Settings screens?
Note that using the above code block gives me the message "your link has expired" when saving plugin options (via the "Save" button on the plugin's settings screen).
What is the best practice for sanitizing plugin settings? | Here's what I found out, with appreciation for the comments to the question.
I write WP code (themes and plugins) and non-WP PHP code (for non-WP sites). In non-WP sites, I include those statements in my 'include' file to ensure POST/GET sanitation, even though I try to sanitize the fields elsewhere. So, sort of a 'sanitize backup plan'.
But putting the code in a WP plugin file too soon kills the plugin's settings screen and/or the front end; more often on the front end with the plugin enabled (result is sometimes a white screen).
So, for WP plugins/themes, I will ensure sanitization of individual POST/GET fields, rather than the above code.
In non-WP sites, though, the above code is benign - sort of a double-check-sanitation thing, even though I try to remember to sanitize POST/GET fields before using that data. | stackexchange-wordpress | {

How do I use the Simple HTML DOM Parser in plugin when other plugin already uses it?

how to display search term in the template full site editor
i am building a template for the search page (in full site editing, therefore html and no php), and i want to have a search results heading. i have this:
<!-- wp:group {"layout":{"inherit":true}} -->
<div class="wp-block-group">
<!-- wp:heading {"level":1} -->
<h1>Search Results</h1>
<!-- /wp:heading -->
</div>
<!-- /wp:group -->
now i have 2 issues:
1- how do i get the search term to display it?
2- how can i translate the "Search Results" string? | I don't think there's a core way to do that in WordPress 5.9 ..
So for now, you can use a custom shortcode which returns the inner HTML/content for the heading (e.g. `Search Results for <search query>` with translation/gettext applied), and then use `<h1>[your-shortcode]</h1>` in your template.
Here's a sample shortcode function that you can try:
add_shortcode( 'your-shortcode', function () {
/* translators: %s: Search query/keyword. */
return sprintf(
__( 'Search Results for "%s"', 'text-domain' ),
esc_attr( get_search_query() )
);
} );
You can also create another shortcode which returns just the search query, if you want to, but remember that you should use `get_search_query()` and **not** `the_search_query()` which echo the output, hence the former should be used in shortcode function which generally should not echo anything. | stackexchange-wordpress | {

Your help is really appreciated. | No, currently gradient support in the heading block has not been implemented.

Access to the template file of a plug-in

2. `locate_template('example-template.php')` to then resolve my (essentially) static template
3. A query within my `example-template.php` that externally retrieves the resource
4. This must handle 404s interally as the response will always assume the post can't be found, I am always setting the header response (before `get_header` in the template to `202` where the resource is found.
5. Example; `if ($resource) { @header($_SERVER['SERVER_PROTOCOL'] . ' 202 Accepted', true, 202); }`

Hide 2022 Parent Theme Templates / Parts

foreach( $categories as $category ) {

}
echo '</ul>';
?> | `get_categories()` gives you an array of `WP_Term` objects, which has the `parent` property. This contains the ID of the parent category.

$parent_id = 123; // change to actual term id
foreach( $categories as $category ) {
if ( $parent_id === $category->parent ) {

What is the practical difference between is_admin() and is_blog_admin()?
I can see that the 2 functions are almost identical. Only difference is in one line:
@is_admin() `return $GLOBALS['current_screen']->in_admin();`
@is_blog_admin() `return $GLOBALS['current_screen']->in_admin( 'site' );`
What is the practical purpose / reason behind this? Or where can i read more about it?
I can see that `is_blog_admin()` 'born' much later, and since it's giving the 'site' parameter to the `in_admin()` function that it calls internally, it works as a stricter condition, thus being more specific and probably not good idea to use it as an 'alias' to 'is_admin()' (since it's not). I just would like to see where this is used in practice? | On a multisite network `is_admin()` is `true` for everything under `/wp-admin`, including the multisite network admin at `/wp-admin/network`, but `is_blog_admin()` is only true for the admin for an individual site/blog on the network, and is _not_ `true` for `/wp-admin/network`. | stackexchange-wordpress | {

How to get and set the post tag value within WP Query from URL?
This is new grounds for me. I'm on a hunt trying to figure out how can use a WPQuery to list all posts, that are filtered by the tag which the user clicked on. So for example if the end-user is on one of my posts, and clicks on a tag that is part of that post, it goes to a new page with the following URL...
`
On that `beaches` page, I know from my child theme I can create a template called tag.php and build & brand the logic for that page. But from this same tag.php template, how can WP Query list all posts that are associated to the tag `beaches` because its the value in the URL? | You don't need to make a new `WP_Query` to display the posts in the requested tag (`beaches` in question), because when the page is requested, WordPress will parse the query args from the URL (or the rewrite rule that matches the URL _path_ ) and automatically make a `WP_Query` call which fetches the tag's posts from the database. And that query is called the "main query" which runs automatically on page load, **before** the template like `tag.php` or `single.php` is determined.
So in your tag template, you just need to display the (main) loop, or the posts for the main query, i.e. `while ( have_posts() ) { the_post(); /* your code here; e.g. call the_title() */ }`.
However, if you wanted to know how to retrieve the current tag object (which is an instance of `WP_Term`), then use `get_queried_object()`. Or `get_queried_object_id()` to retrieve just the tag ID.

How to upload images in a specific folder using API
I have installed wordpress plugins Real Media library, Real Physical Media, and Media file renamed. Using this I am able to physically move images and organize images in the upload folder as per categories. Both these plugins have API - < <
but they don't seem to provide any option to upload files.
It means for uploading I still need to use the classic Wordpress rest API.

Or directly while uploading itself I can set the destination folder. | The problem is solved.

What is the significance of 'root' in getEntityRecords?
I've gone through the documentation and the source code but I couldn't understand.
I have 2 queries:
`getEntityRecords( 'postType', 'post' );` and `getEntityRecords( 'root', 'user' )`.
1. Why does the 2nd query require `root` as the 1st argument?
2. What does it mean?
3. How to determine when to use it?
The doc describes the parameters of `getEntityRecords` as following:
**Parameters:**
* state **Object** : State tree
* kind **string** : Entity kind.
* name **string** : Entity name.
* query **?Object** : Optional terms query.
4. Are `postType` and `root` both state trees?
5. How does `state` relate to `kind` while referring to entities.js? | The important thing to note is that `post` is a kind/sub-type of the post types entity, all posts regardless of type share the same table and general data structure and fields etc.
This contrasts with other major entity types such as comments or users.
However, what if there is no kind or sub-type? What if your entity is a user? What would you put as the entity kind/sub-type? There is only 1 kind of user! So you go one level up, and that's where `root` comes from.
It's also useful to know that entities are very related to the REST API and endpoints, and that this is the only connection to the PHP side of things. Entities only exist in the WP javascript packages. It's possible to use the REST API and javascript without referring to entities on the frontend, but if you're working with the block editor it's highly relevant. | stackexchange-wordpress | {

Substitute original WordPress url by another domain name

How to find what pages/posts contain a particular reusable block?

Any pointers please? | Funny how you find the answer just after posting a question. Posting here, in case someone comes looking for it.
As per @Kero's comment above, that's correct. The command-line option will only recognise strings.
There is however an eval-file command that can be used to achieve this (and now that I have discovered it, a lot more).
Here are the steps for achieving the goal I posted in my question, however as the eval-file WP CLI command can be used to execute a PHP file, we can code anything that we deem fit.

<?php
set_theme_mod('my_boolean_mod', false);
set_theme_mod('my_array_mod', array(1, 2, 3));
The above code will use the WordPress set_theme_mod function to create/update mods named my_boolean_mod and my_array_mod.
Step 2: Execute the above file using the WP CLI eval-file command

How do I add a custom sub menu menu under Woo-commerce marketing?
I am developing a plugin and I want to add a menu under the woo-commerce marketing menu like the coupons and overview submenus. How am able to archieve that?
I did this but it didn't work.
add_submenu_page(
'admin.php?page=wc-admin&path=/marketing',
__( 'Sub Menu' ),
'manage_woocommerce',
'sub-menu-slug',
'sub_menu_page_callback'
); | If available the `$GLOBALS[ 'menu' ]` array holds data for each top level menu item in the dashboard, and in the sub array for the Woocommerce "Marketing" menu item, key 2 has the value you're looking for: `"woocommerce-marketing"`.
So with that your `add_submenu_page` should look like the below to make your sub menu item show up under the Woocommerce Marketing menu item:
add_submenu_page(
'woocommerce-marketing',
__( 'Sub Menu' ),
'manage_woocommerce',
'sub-menu-slug',
'sub_menu_page_callback'

add_action( 'woocommerce_shop_loop_item_title', [ $this, 'product_title' ], 10 );
}
}
Are there any conventions or should I strive for consistency?
NOTE: In Laravel projects I always use verbs because each method is doing something. | > Are there any conventions or should I strive for consistency?
No, as long as your actions are readable, unique, and it's clear what they do, there is no rule to follow.
Ideally the names you choose are consistent within the code you write. E.g. WooCommerce has chosen to use the `woocommerce_` prefix, or when ACF uses `acf\`. If you think verbs works for you then use verbs, just do it consistently and clearly.
The one thing I would say, is never have a fully dynamic name, e.g. passing a variable from a separate source assuming they're all unique, e.g. `add_action( $form_name, '...`. | stackexchange-wordpress | {

Gutenberg: How to check if a block is used in a paginated post?
There is the `render_callback` of the `register_block_type` function. In this callback, I can use `add_filter('render_block', __NAMESPACE__ . '\\filter_block', 10, 2);`
`filter_block` iterates through all blocks in my post ... until the post is paginated, and the block is on page 1, but I want to check blocks on page 3 of the post.
I found the function `has_block` but how to I combine this with the `render_callback`? The callback is only executed when the block is rendered. Is there a function for this I am missing? Like a callback `used_in_post_callback` or something like this? | The solution is simple:
has_block( 'simpetoc/toc, $YOUR_POSTS_CONTENT_OR_POST_ID )
<
> has_block( string $block_name, int|string|WP_Post|null $post = null )
There is no need to render the blocks to build a table of contents, nor should you do it that way.

Why does get_dirsize return the same size?
The function below is intended to return the size of the base directory. Although additional files have been uploaded, it continues to display the same size. What am I missing?
function get_space_used() {
$upload_dir = wp_upload_dir();
$space_used = number_format( get_dirsize( $upload_dir['basedir'] ) / ( 1024 * 1024 ), 1 );
return $space_used;
} | Under the hood, `get_dirsize()` uses `recurse_dirsize()` which uses a transient called `dirsize_cache`. Try clearing that transient and check again.
To do so, you can use one of the following methods:
* call `delete_transient('dirsize_cache');`
* use WP CLI's `wp transient delete`
* use a plugin
* * *
Looking further through the source code, I think it should be possible to use `recurse_dirsize()` directly in your code and telling it not to cache like so:
$upload_dir = wp_upload_dir();
$size = recurse_dirsize($upload_dir['basedir'], null, null, []);
By passing an empty array `[]` as the fourth argument, it should circumvent the cache because the `!isset($directory_cache)` now returns a different result. | stackexchange-wordpress | {

Wordpress SQL LIKE request doesn't work for fields with special symbols
In WordPress I make SQL-requests to the database but LIKE request doesn't work correctly.
Actial value of `meta_value` field in the database is such string:
a:1:{i:0;s:9:"full-time";}
if I make this request all works fine:
$query = $wpdb->prepare("SELECT meta_value FROM wp_postmeta WHERE meta_key = 'job_bm_job_type' AND meta_value LIKE '%a%' LIMIT 1");
But if try to use other text in LIKE part I don't get any results
$query = $wpdb->prepare("SELECT meta_value FROM wp_postmeta WHERE meta_key = 'job_bm_job_type' AND meta_value LIKE '%full%' LIMIT 1");
Ideally, LIKE request should search through data of all the string. But it seems like it doesn't search inside the content of square brackets `{ }`
What I miss here? How to search through any elements in this field? | I found the answer.
Like @Sally-CJ mentioned above, `%f` in the beginning was mistakenly seen as one of supported placeholders for wpdb::prepare() (the other two placeholders are `%s` and `%d`).
So you need to add escaping the quotes `\"`. In my case it's `\"full\"`. With escaping it works perfectly.
$query = $wpdb->prepare("SELECT meta_value FROM wp_postmeta WHERE meta_key = 'job_bm_job_type' AND meta_value LIKE '%\"full\"%' LIMIT 1");
If you search string starts from letter `a`, `d`, `f` – this finding could help you solve the problem. | stackexchange-wordpress | {

How to enable [archives] short code
I want to use the `[archives type=yearly]` short code on a side bar widget so that people can click on links and see posts for the year. But this is the result I'm getting:

Keeping and updating ACF and ACF Pro at the same time
I am not sure how far this is relevant on this platform. Actually I am in a situation where I have both `ACF` _(Deactivated)_ and `ACF Pro` **(Activated)** installed at the same time in a single WordPress site.
The Pro version is running the latest ( **v 5.12** ). But the Non-pro version is falling behind a few (minor) updates. Current version is **5.11** to be exact.
I am a bit confused about updating the `ACF` (non pro) version because it is deactivated and ideally should not create any problem. But at the same time, keeping an old plugin, whether it is activated or not, is not recommended. And, at the same time hesitating to remove it completely for any unwanted impact!
Is this safe to update / remove the plugin? What should be the correct way to test for any impact that might happen if I remove the non-pro version? | As the free is deactivated, the code inside is not used. You can delete it.

Use a filter for wp_robots to block CPT/feed/
We have a CPT (with base slug `templates`) that somehow included in every single post's head a link to `/templates/post/feed/`.
I've removed this link to the feed from the head, but want to block robots from the feed also.
From this answer, I can adapt code like:
add_filter( 'wp_robots', function( $robots ) {
if ( is_singular( 'templates' ) ) {
$robots['noindex'] = true;
$robots['nofollow'] = true;
}
return $robots;
} );
but don't know how to include is_feed() into this code.
Would I use something like `if ( is_singular( 'templates' ) && is_feed( 'templates' ) )` ?
Help appreciated.
**EDIT**
Alternatively, I could somehow add the following to `robots.txt`:
User-agent: *
Disallow: /templates/*/feed
but do not know the function/hook to do this. We're using `Yoast SEO`.

Prevent WordPress from automatically installing a new theme each year

Override htacces rule only for specific directory
I have a WordPress site with ithemes security installed plugin. I want to disable this rule:
RewriteCond %{HTTP_USER_AGENT} "^$" [NC,OR]
only for this `wp-content/uploads/xmls` directory.
Relevant (summarised) section of `.htaccess` file:
# Begin HackRepair.com Blacklist
RewriteEngine on
# Abuse Agent Blocking
RewriteCond %{HTTP_USER_AGENT} ^[Ww]eb[Bb]andit [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^$ [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^Acunetix [NC,OR]
:
: etc.
:
RewriteCond %{HTTP_USER_AGENT} YisouSpider [NC,OR]
RewriteCond %{HTTP_USER_AGENT} zermelo [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ZyBorg
RewriteRule ^.* - [F,L]
# Abuse bot blocking rule end | To effectively disable that _condition_ for that one URL-path, you will need to add another rule immediately before the rule in question. ie. _before_ the `# Abuse Agent Blocking` comment.
For example:
# Allow an empty User-Agent for requests that start "/wp-content/uploads/xmls"
RewriteCond %{HTTP_USER_AGENT} ^$
RewriteRule ^wp-content/uploads/xmls - [S=1]
# Abuse Agent Blocking
RewriteCond %{HTTP_USER_AGENT} ^[Ww]eb[Bb]andit [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^$ [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^Acunetix [NC,OR]
: etc.
The first rule _skips_ the following rule if the requested URL-path starts `/wp-content/uploads/xmls` and the `User-Agent` header is empty. So, it effectively bypasses the rule that would otherwise block it.
This does assume that the request maps to a physical file in that directory. ie. Not a request that would otherwise be rewritten to the WordPress front-controller (`index.php`). | stackexchange-wordpress | {

Calling add_action on a filter hook?
I'm working with Ultimate Member plugin and while attempting to work through a modification I accidentally used `add_action` on a filter hook (not an action hook) and it still worked - as in the call back ran??

below is the code I ran. N.B no `return` either.
Here is a link to the UM docs about this filter hook um_set_user_role

function add_user_specific_role( $role, $user_id, $user ) {
error_log( '============= UM NEW ROLE =================' );
error_log($role);
error_log( '============= UM USER ALL ROLES =================' );
error_log(print_r($user->roles, true));
} | `add_action()` and `add_filter()` are essentially the same thing, hooks, and they both call the same functions under the hood. If you look you'll see `WP_Hook::do_action()` basically just calls `WP_Hook::apply_filters()`.
An action is essentially just a filter that doesn't return a value. If your callback function was supposed to modify the value of `$role` then that part wouldn't work, because `add_action()` won't pass the value through, but the callback will still run, as you've seen. | stackexchange-wordpress | {

Custom Wordpress Plugin will install new and not update
I've just created my first custom Wordpress plugin. Now I want to push a new version:
Recreation Steps:
* Install v1.1.0
* Activate v1.1.0
* See that is doing stuff -> YEAH
* Create new Zip with v1.1.2 and inside set "Version: 1.1.2"
* Go to Wordpress -> Add New and pick that zip
* Wordpress will install new plugin and not ask to overwrite...
Can someone explain to me what I'm doing wrong?
Kind Regards, Ben | A plugin is treated as the same as another plugin if it has the same directory name. That's it. If your zip file contains the plugin files then the zip filename will be used as the directory name. If your zip has a directory in it, containing the plugin files, then that will be used as the plugin directory.
So the solution is to structure your zips like this:
my-plugin-1.0.0.zip
∟ my-plugin/
∟ my-plugin.php
my-plugin-1.1.0.zip
∟ my-plugin/
∟ my-plugin.php
This way the directory will always be `my-plugin/` and those two zips will be treated as the same plugin. | stackexchange-wordpress | {

Page with custom template make get request to a custom route - Pseudo code

Thank you for your help | I am assuming you are trying to retrieve data from that route and display that to the end user?
Instead of using the rest API to retrieve that information, you could put the callback function directly into your template file and then use the php $_GET variable (php docs) to pass the search term into your function. I think it would look like something like this:

$url_param = $_GET['myterm'];
if(empty($url_param)){
echo "Search term missing, please try again.";
}
