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.
Usage
add_filter( 'get_(meta_type)_metadata_by_mid', 'filter_function_name_7617', 10, 2 ); function filter_function_name_7617( $value, $meta_id ){ // filter... return $value; }
- $value(stdClass/null)
- The value to return.
- $meta_id(int)
- Meta ID.
