我已经创建了分类法，但我想为分类法使用不同的post模板，我该怎么做？

function create_topics_hierarchical_taxonomy() {

// Add new taxonomy, make it hierarchical like categories
//first do the translations part for GUI

  $labels = array(
    \'name\' => _x( \'cars\', \'taxonomy general name\' ),
    \'singular_name\' => _x( \'cars\', \'taxonomy singular name\' ),
    \'search_items\' =>  __( \'Search Topics\' ),
    \'all_items\' => __( \'All Topics\' ),
    \'parent_item\' => __( \'Parent Topic\' ),
    \'parent_item_colon\' => __( \'Parent Topic:\' ),
    \'edit_item\' => __( \'Edit Topic\' ), 
    \'update_item\' => __( \'Update Topic\' ),
    \'add_new_item\' => __( \'Add New Topic\' ),
    \'new_item_name\' => __( \'New Topic Name\' ),
    \'menu_name\' => __( \'cars\' ),
  );    

// Now register the taxonomy

  register_taxonomy(\'cars\',array(\'post\'), array(
    \'hierarchical\' => true,
    \'labels\' => $labels,
    \'show_ui\' => true,
    \'show_admin_column\' => true,
    \'query_var\' => true,
    \'rewrite\' => array( \'slug\' => \'cars\' ),
  ));
