deleted_meta_type_meta action

The dynamic portion of the hook name, $meta_type, refers to the meta object type (post, comment, term, user, or any other type with an associated meta table).

To use deleted_meta_type_meta action, first you have to register it using add_action. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function execute_on_deleted_meta_type_meta_event which takes 4 parameters and we registered using add_action. The first parameter deleted_meta_type_meta is name of the hook, The second parameter execute_on_deleted_meta_type_meta_event is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_action to remove deleted_meta_type_meta action.


    Below are the 4 parameters are required to use this hook.

  • $meta_ids : (string[]) An array of metadata entry IDs to delete.
  • $object_id : (int) ID of the object metadata is for.
  • $meta_key : (string) Metadata key.
  • $_meta_value : (mixed) Metadata value.

Live Example

do_action( "deleted_{$meta_type}_meta", string[] $meta_ids, int $object_id, string $meta_key, mixed $_meta_value )

Below is an example how you can use this hook.

                        function execute_on_deleted_meta_type_meta_event($meta_ids, $object_id, $meta_key, $_meta_value){
                           //You can write code here to be executed when this action occurs in WordPress. Use the parameters received in the function arguments & implement the required additional custom functionality according to your website requirements.
                        // add the action
                        add_action( "deleted_meta_type_meta", "execute_on_deleted_meta_type_meta_event" , 10, 4);

To remove a hook callback, use the example below.

remove_action( "deleted_meta_type_meta", "execute_on_deleted_meta_type_meta_event", 10, 4 );

Please make sure provide the same callback function name, priority and number of arguments while removing the hook callback.
