I won't go into the ugly details on why I need this, but I need to fire an event (a PHP function) after a menu is saved (new or updated). I need to have access at a point after the save happens so that I can get the new menu to output.
I have tried:
add_action('wp_update_nav_menu', 'fwp_save_nav', 999);
This almost does what I want, but it fires before the save. Anyone have any thoughts?
