When Choosing an answer as the best answer the Question should be marked as resolved

Hi vahid,
I made a snippets here to auto reolve question when the author of question mark an answer to become the best answer:

function hook_on_metadata( $meta_id, $object_id, $meta_key, $_meta_value ) {
    if( $meta_key == '_dwqa_best_answer' && is_user_logged_in() ) {
        global $current_user;
        $author_id = get_post_field( 'post_author', $object_id );
        if( $author_id == $current_user->ID ) { // If the author of question mark the best answer
            update_post_meta($object_id, '_dwqa_status', 'resolved' );
        }
    }
}
add_action( 'added_post_meta', 'hook_on_metadata', 10, 4 );
add_action( 'updated_post_meta', 'hook_on_metadata', 10, 4 );

Hope this help.
Regards
