WordPress custom taxonomy link not highlighted under custom admin menu

4 comments

1. Ok, for all folks who run into the same issue..

   What you are doing is:

   1. Creating a custom menu using add_menu_page
   2. Creating a custom post type / taxonomy
   3. Trying to push your custom taxonomy edit link under your new menu

   Do this instead:

   1. Do not create any menu manually (!)
   2. When adding custom post type, do not set 'show_in_menu' argument – this will create a menu for you. You can control where it appears by setting a 'menu_position' under the same args array.
   3. Use this newly created menu for all other custom pages that you want to add. When calling add_submenu_page, use 'edit.php?post_type=%%post_type_name%%' as a parent slug (the first param).

   Simply – don’t do the other way around 🙂

   Thanks to Obmerk Kronen and stink who tried to help. Appreciate this.

2. I was looking for the same thing, but I did not want the to use the Custom Post Type as the main menu.

   I eventually found this link on the WP.org support forum http://wordpress.org/support/topic/moving-taxonomy-ui-to-another-main-menu

   Code outlined below.

   function recipe_tax_menu_correction($parent_file) {
       global $current_screen;
       $taxonomy = $current_screen->taxonomy;
       if ($taxonomy == 'ingredient' || $taxonomy == 'cuisine' || $taxonomy == 'course' || $taxonomy == 'skill_level')
           $parent_file = 'recipe_box_options';
       return $parent_file;
   }
   add_action('parent_file', 'recipe_tax_menu_correction');

3. You could use this as a template or just use this taxonomy generator like I did.

   // Register Custom Taxonomy
   function Stack_Overflow()  {
   
   $labels = array(
       'name'                       => _x( 'Question', 'Taxonomy General Name', 'stack_overflow' ),
       'singular_name'              => _x( 'Question', 'Taxonomy Singular Name', 'stack_overflow' ),
       'menu_name'                  => __( 'Stack Overflow', 'stack_overflow' ),
       'all_items'                  => __( 'All Questions', 'stack_overflow' ),
       'parent_item'                => __( 'Language', 'stack_overflow' ),
       'parent_item_colon'          => __( 'Framework', 'stack_overflow' ),
       'new_item_name'              => __( 'New Question', 'stack_overflow' ),
       'add_new_item'               => __( 'Ask Question', 'stack_overflow' ),
       'edit_item'                  => __( 'Edit Question', 'stack_overflow' ),
       'update_item'                => __( 'Edit Question', 'stack_overflow' ),
       'separate_items_with_commas' => __( '', 'stack_overflow' ),
       'search_items'               => __( 'Search Questions', 'stack_overflow' ),
       'add_or_remove_items'        => __( 'Add or Remove Questions', 'stack_overflow' ),
       'choose_from_most_used'      => __( 'Choose from the most popular languages', 'stack_overflow' ),
   );
   $rewrite = array(
       'slug'                       => 'questions',
       'with_front'                 => true,
       'hierarchical'               => true,
   );
   $args = array(
       'labels'                     => $labels,
       'hierarchical'               => true,
       'public'                     => true,
       'show_ui'                    => true,
       'show_admin_column'          => true,
       'show_in_nav_menus'          => true,
       'show_tagcloud'              => true,
       'query_var'                  => 'question',
       'rewrite'                    => $rewrite,
       'update_count_callback'      => 'display_edit_count',
   );
   register_taxonomy( 'stakoverflow', 'page', $args );
   
   }
   
   // Hook into the 'init' action
   add_action( 'init', 'Stack Overflow', 0 );

4. @sPaul what you referenced in your answer works for custom post types but not for taxonomies. There isn’t a 'menu_position' arg for custom taxonomies. What you had done in your question will work fine to create the link under your menu:

   add_submenu_page(
       'virtual',
       __('Virtual Product Categories', $this->text_domain),
       __('Categories', $this->text_domain),
       'edit_products',
       'edit-tags.php?post_type=virtual_product&taxonomy=virtual_product_cat'
   );
   

   But to get it to show the correct styles you’ll need to add some JS to add / remove classes. Here’s how (modified from https://wordpress.stackexchange.com/a/225228/80088):

   add_action( 'admin_head-edit-tags.php', 'modify_menu_highlight_wpse_43839' );
   
   function modify_menu_highlight_wpse_43839()
   {
       if( 'virtual_product_cat' == $_GET['taxonomy'] )
       {       
           ?>
           <script type="text/javascript">
               jQuery(document).ready( function($) 
               {
                   $("#menu-posts, #menu-posts a")
                       .removeClass('wp-has-current-submenu')
                       .removeClass('wp-menu-open')
                       .addClass('wp-not-current-submenu'); 
                   $("#toplevel_page_ virtual, #toplevel_page_ virtual > a")
                       .addClass('wp-has-current-submenu');
               });     
           </script>
           <?php
       }
   }
