Hook after meta created

Question

I'm having troubles trying to do a hook when post published. I think that the problem is that my WP-Metaboxer plugin creates the meta after publishing post, and I cannot capture the value.

Here is an example:

function post_published_coins_update( $ID, $post ) {    
        $tipo = get_post_meta( $post->ID, 'tipo');

        $coins_value = $tipo;

        add_user_meta($post->post_author, 'coins', $coins_value);
    }
add_action('publish_post', 'post_published_coins_update',  10, 2);

I've created a metabox that create a post_meta called "tipo", but the hook doesn't access to it, is like if the hook starts before than the meta creates.

Any idea?

Thanks!

There is a dynamic hook right before any new metadata is added:

do_action( "add_{$meta_type}_meta", $object_id, $meta_key, $_meta_value );

It would be add_post_meta for posts accordingly.

Note that you might to tinker some to catch this precisely in the case of new post being created, for example hook into publish_post first, note the ID, and add to this hook from there.
