get_(meta_type)_metadata_by_mid filter-hook . WP 5.0.0

Filters whether to retrieve metadata of a specific type by meta ID.

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

Usage

add_filter( 'get_(meta_type)_metadata_by_mid', 'filter_function_name_6316', 10, 2 );
function filter_function_name_6316( $value, $meta_id ){
	// filter...

	return $value;
}

$value(mixed)

The value get_metadata_by_mid() should return.

$meta_id(int)

Meta ID.
