 * Hi guys,
 * I’m trying to get the ID of the post being edited from within the register_my_custom_fields
   function, and having tried a number of different methods I’ve hit a brick wall.
 * I’ve tried…
    global $post; $post_id = $post->ID; global $post; $post_id = ($post_id)?(
   $post_id):($post->ID); global $wp_query; $post_id = $wp_query->post->ID; $post_id
   = the_ID();
 * But as I said before, its always blank.
 * The reason for wanting the ID at this stage is so I can check on the value of
   other meta fields and show additional fields in response.
 * Any ideas?
