[resolved] save_post equivalent when saving a field (3 posts)

    I have a custom 'save_post' action defined in my functions.php which checks the value of a certain post_meta field and based on that value, updates a different post_meta field. This works all nice and happy.
    I am using editable_post_meta() for the post_meta field that needs to be checked. Obviously, when just this one field is saved, it doesn't trigger the 'save_post' action... I'm not saving the whole post, just this field.
    Is there a way to trigger a wordpress action or php function when just that field is saved? Is there a custom action ('save_meta') or something that I can do that will be triggered when this field is updated?

    Nevermind. I discovered the 'updated_post_meta' action. All good!

    For those of you interested

    function functionname($meta_id, $post_id, $meta_key, $meta_value) {
    add_action( 'updated_post_meta', 'functionname', 10, 4 );
