    Hi,
    I am working with a client and would like that every time they add a category, it is automatically added as a sub-menu item in the Primary navigation menu. The categories are in a custom post type with ‘project’ as the taxonomy name. I’d like to avoid a plugin if possible.

    I’ve been poring through wp’s filters and am struggling to come up with a working code. It seems like a simple li loop with get_items() but I am stuck. Any help on this would be greatly appreciated.

  • You can use the wp_nav_menu_objects filter. Try this (haven’t tested it yet):

       add_filter( 'wp_nav_menu_objects', 'wpg2byt_add_term_parent' );
    function wpg2byt_add_term_parent( $items ) {
      $terms = get_terms( array(
        'taxonomy' => 'project',
        'hide_empty' => false,
     ) );
  
      foreach ($terms as $term) {
      //format its data to be compatible with the filter
      $link = array (
            'title'            =>  $term->name,
            'menu_item_parent' => //id of the parent menu,
            'ID'               => '',
            'db_id'            => '',
            'url'              => get_term_link($term)
        );
      $items[] = (object) $link;
      }
      return $items;    
    }

    Hi Joms, this did the trick. Added a couple things (for anybody else who might want to use this) including grabbing the term_id and appending the classes. I appreciate the help!

    add_filter( 'wp_nav_menu_objects', 'wpg2byt_add_term_parent' );
    function wpg2byt_add_term_parent( $items ) {
      $terms = get_terms( array(
        'taxonomy' => 'project',
        'hide_empty' => false,
    ) );
      foreach ($terms as $term) {
      //format its data to be compatible with the filter
      $link = array (
            'title'            => $term->name,
            'menu_item_parent' => //id of the parent menu,
            'ID'               => $term->term_id,
            'db_id'            => '',
            'url'              => get_term_link($term),
            'classes'          => array( 'my-classes' )
        );
      $items[] = (object) $link;
      }
      return $items;   
    }
