我有一个自定义的帖子类型，即services &；自定义分类法services_type

我的自定义永久链接结构为/%类别%/%postname%

term1,term2,term3 在services\\u type taxonomy下有不同的术语；post1,post2,post3,post4 是帖子

我我想知道的是

http://example.com/term1/post1
http://example.com/term1/post2
http://example.com/term2/post3
http://example.com/term3/post4

以下是我到目前为止使用的内容

function wpt_services_posttype() {
  register_post_type( \'services\',
    array(
        \'labels\' => array(
        \'name\' => __( \'Services\' ),

      ),
      \'public\' => true,
      \'supports\' => array( \'title\',\'editor\',\'thumbnail\',\'page-attributes\',\'custom-fields\'),
      \'capability_type\' => \'post\',
      \'rewrite\' => array("slug" => "services/%services_type%"), // Permalinks format
      \'menu_position\' => 6,         
      \'show_ui\'=>true,
      \'query_var\'=>true

      )
  );
}
add_action( \'init\', \'wpt_services_posttype\' );

//code for adding texonomy
function services_init() {
  // create a new taxonomy
  register_taxonomy(
    \'services_type\',
    \'services\',   
    array(
      \'labels\' => array(
              \'name\'=>\'services type\',
              \'add_new_item\'=>\'Add New type \',
              \'new_item_name\'=>"New type" ,

              ),

      \'show_ui\' => true,
      \'show_tagcloud\' => false,
            \'hierarchical\' => true,
      \'rewrite\' => array( \'slug\' => \'services\' ),
         )
  );
}

add_action( \'init\', \'services_init\' );


add_filter(\'post_type_link\', \'services_permalink_structure\', 10, 4);
function services_permalink_structure($post_link, $post, $leavename, $sample)
{
    if ( false !== strpos( $post_link, \'%services_type%\' ) ) {
        $service_type_term = get_the_terms( $post->ID, \'service_type\' );
        $post_link = str_replace( \'%services_type%\', array_pop( $service_type_term )->slug, $post_link );
    }
    return $post_link;
}

请帮忙
