get_(meta_type)_metadata_by_mid filter-hook . WP 5.0.0

Short-circuits the return value when fetching a meta field by meta ID.

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( 'get_(meta_type)_metadata_by_mid', 'filter_function_name_2344', 10, 2 );
function filter_function_name_2344( $value, $meta_id ){
	// filter...

	return $value;
The value to return.
Meta ID.


Since 5.0.0 Introduced.
