How to use deleted_meta_typemeta action in WordPress

When diving into the world of WordPress development, hooks are an essential part of customizing and extending the functionality of your site. Today, we’re exploring the deleted_meta_typemeta action. This hook is dynamic and based on the type of meta object you are working with, be it a post or comment.

To get started with deleted_meta_typemeta, you need to register it using add_action. You can place this code in your theme’s functions.php or, better yet, in a custom WordPress plugin. Creating a custom plugin ensures your changes persist through theme updates.

Here at WePlugins, we always recommend crafting a custom plugin when working with hooks to keep everything smooth and future-proof.

Example 1: Basic Usage of deleted_meta_typemeta

To trigger an action when a meta entry is deleted, you can use the following code:

    function weplugins_execute_on_deleted_meta_typemeta_event($meta_ids){
        // Code to execute when this action occurs
    }
    add_action( "deleted_meta_typemeta", "weplugins_execute_on_deleted_meta_typemeta_event", 10, 1 );
    

Example 2: Removing the Hook

If you need to remove a previously registered hook, you can use remove_action as shown below:

    remove_action( "deleted_meta_typemeta", "weplugins_execute_on_deleted_meta_typemeta_event", 10, 1 );
    

Ensure that the callback function name, priority, and number of arguments match exactly when removing a hook.

Example 3: Dynamic Hook with Meta Type

Here’s how you can use the dynamic aspect of the hook to work with different meta types:

    do_action( "deleted_{$meta_type}meta", int $meta_ids );
    

Replace $meta_type with the specific meta type you’re working with, like ‘post’ or ‘comment’.
