Custom taxonomy admin page

2 comments

1. Not sure why I didn’t think of this earlier. I suppose I was hoping for a way to ‘hijack’ the default page to display something else… Anyway following my original method:

   If you want a custom admin page for a taxonomy, you can set ‘show_ui’ => false when you register it to suppress the default admin page and then create a new admin page to replace it.

   You can get round the issue of edit-tags.php?taxonomy=taxonomy-slug taking you to the hidden taxonomy page, by simply redirecting the user to your page, using wp_redirect:

   add_action('load-edit-tags.php','myprefix_redirect_to_custompage');
   function myprefix_redirect_to_custompage(){
       $screen = get_current_screen(); 
       if($screen->id == 'edit-mytax'){
           $url = admin_url('edit.php?page=mypage');
           wp_redirect($url); 
           exit;
       }
   }
   

   Assuming mytax is the taxonomy name. $url should be the url of the custom page replacing the default taxonomy page.

2. Do a simple redirect:

   if ( CONDITION_SEE_BELOW )
   {
       wp_redirect( admin_url( 'edit.php?post_type=YOUR_CPT', is_ssl() ? 'https' : 'http' ); );
       // faster then die();
       exit;
   }
   

   I tried to take the whole pages thing apart and wrote a table to sum them up and get definitive hints about where you currently are in this paste.

   To list them here:

   1. global $menu → not possible
   2. global $submenu → slug edit-tags.php?taxonomy=YOUR_TAX
   3. global $current_screen → id edit-YOUR_TAX ¹⁾
   4. global $self → edit-tags.php ^{1) 2)}
   5. $GLOBALS['$_SERVER']['REQUEST_URI'] → edit-tags.php?taxonomy=YOUR_TAX ¹⁾

   ---

   ¹⁾ Be sure to also check…

   if ( edit.php?post_type=YOUR_CPT === $GLOBALS['current_screen']['parent_file'] )

   …in case your tax is registered elsewhere too.

   ²⁾ This will only help if a) you’re that you ain’t got another tax registered or b) if you want to redirect them all.
