Is there an explicit action hook that will fire when (or just before) the admin Edit page renders for a custom post type? Something similar to {$new_status}_{$post->post_type}?
I’m trying to find the least obtrusive place to insert my add_meta_box() registration so that it’s not calling that function on every page refresh, but only when it’s needed (ie: the user wants to create a new custom post or edit an existing custom post).
Thanks for your thoughts / code snippets!
register_post_type()
has a registration option called'register_meta_box_cb'
. Set that to a valid callback and it will call that function only when it is compiling the meta boxes for that post type’s edit screen. Something like this:
