update_(meta_type)_metadata_cache filter-hook . WP 5.0.0

Short-circuits updating the metadata cache of a specific type.

The dynamic portion of the hook, $meta_type, refers to the meta object type (post, comment, term, user, or any other type with an associated meta table). Returning a non-null value will effectively short-circuit the function.


add_filter( 'update_(meta_type)_metadata_cache', 'filter_function_name_7057', 10, 2 );
function filter_function_name_7057( $check, $object_ids ){
	// filter...

	return $check;
Whether to allow updating the meta cache of the given type.
Array of object IDs to update the meta cache for.
