When you save a post, then you are basically submitting a big <form>. This form has an action pointing somewhere. Now there are two possibilities how the form is processed: AJAX (background reload) Default <form> handling (new request) Basic form submitting is adding a new request (2), so the data gets processed and then the … Read more
You aren’t filtering correctly. Firstly, you aren’t passing variables to the function, so your function has no way of knowing what $comment_author is, etc. If you had debug mode enabled you’d probably get errors about undefined variables. Secondly, you need to return a value. Untested, but seems like it ought to work: add_filter(‘pre_comment_approved’, ‘custom_blacklist’, 10, … Read more
You will want to use the post_row_actions filter https://developer.wordpress.org/reference/hooks/post_row_actions-2/ For example, to add a link, you could try something like: function add_custom_link($actions, $page_object) { $actions[‘custom_link’] = ‘<a href=”http://www.example.com”>My Custom Link</a>’; return $actions; } add_filter(‘post_row_actions’, ‘add_custom_link’, 10, 2);
It’s important to always return the value in filter callbacks, otherwise it’s like adding the __return_null() callback. Here’s an example that adds the blog class only to page with ID 40: add_filter( ‘body_class’, ‘add_blog_to_body_class’ ); function add_blog_to_body_class( $classes ) { if ( is_page( 40 ) ) $classes[] = ‘blog’; return $classes; }
add_filter() has other 2 optionals parameters (same for add_action()), the priority (default set to 10, and lower numbers correspond with earlier execution) and the number of args (default to 1). You need to set your filter with the priority with an higher priority than the other plugin, assuming the other has its priority to the … Read more
You can use the pre_get_posts hook – the following code assumes your input name is event_date, and the values are in the format YYYY-MM. It runs a few checks (is the input non-empty, are we in the admin, is this the main query, and is this for events?) before generating a meta query, which is … Read more
We can simplify the mime type checks, with the following boolean functions: wp_attachment_is( ‘image’, $id ) wp_attachment_is( ‘video’, $id ) wp_attachment_is( ‘audio’, $id ) where $id is the attachment ID. The attachment’s ID is actually one of the input arguments for the media_send_to_editor filter callback. We also have: wp_attachment_is_image( $id ) that’s a wrapper for … Read more
Filters come with a priority parameter, the default is 10, so to override a function you need to increase the priority: add_filter( ‘wcml_switch_currency_exception’, ‘cart_switching_currency’, 99, 4 ); add_filter( string $tag, callable $function_to_add, int $priority = 10, int $accepted_args = 1 ) More info in the add_filter Update: If removing a filter is not working you … Read more
When you add functions to the same handle without specifying the priority, they are executed in the order of addition. Every time you try to send an email, all the hooked functions will be called in the order in which they were added. To turn on email sending while a function runs, you can: remove … Read more
Have you tried using parse_blocks() (pass in get_the_content())? That returns an array of all the blocks in your content. From there you can pull out block names and id attributes using an array map or foreach. Assuming you only want to pull anchor tags from the headings, you could do something like: $blocks = parse_blocks( … Read more
