我很难弄清这一点，我所要做的就是为自定义分类法创建一个完美的逻辑URL结构。

我有一个CPT：\'knowledgebase\'

我得到的最接近的结果是：

• domain.tld/topics/%knowledgebase_topic%

  当前分类法和CPT代码：

  register_post_type( \'knowledgebase\',
          array(
              \'labels\'    => array(
                  \'name\'  => __( \'Knowledgebase\' ),
                  \'singular_name\' => __( \'Article\' )
              ),
          \'public\'        => true,
          \'has_archive\'   => true,
          \'rewrite\'       => array( \'slug\' => \'knowledgebase\' ),
          \'taxonomies\'    => array(\'knowledgebase_topics\'),
          \'menu_position\' => 20,
          \'menu_icon\'     => \'dashicons-sos\',
          \'supports\'      => array( \'title\', \'editor\', \'excerpt\', \'thumbnail\' )
          )
      );
  
  register_taxonomy(
        \'knowledgebase_topics\',
        \'knowledgebase\',
        array(
          \'labels\'       => array(\'name\' => \'Topics\' , \'singular_name\' => \'Topic\', \'add_new_item\' => \'Add new topic\', \'not_found\' => \'No topics found\' ),
          \'hierarchical\' => true,
          \'rewrite\'      => array( \'hierarchical\' => true, \'slug\' => \'topics\' ),
          \'capabilities\' => array( \'edit_terms\' => \'manage_categories\' )
        )
      );
  

  那么我错过了什么把戏呢？
