How to use delete_meta_typemeta action in WordPress

Example 1: Basic Usage

This example demonstrates how to execute a function whenever a meta is deleted. It’s like setting up a trigger for a specific event.

        function weplugins_execute_on_delete_meta_typemeta_event($meta_id) {
            // Custom functionality to execute on meta delete
        }
        add_action("delete_meta_typemeta", "weplugins_execute_on_delete_meta_typemeta_event", 10, 1);
        

Example 2: Removing a Hook

Sometimes, you might need to remove a previously registered hook. Here’s how you can do it effectively.

        remove_action("delete_meta_typemeta", "weplugins_execute_on_delete_meta_typemeta_event", 10, 1);
        

Example 3: Dynamic Hook Usage

The dynamic part of this hook, $meta_type, adapts based on whether you’re dealing with a post or comment meta. Here’s how you can dynamically call this hook.

        do_action("delete_{$meta_type}meta", $meta_id);
