我正在尝试创建我的网站页脚部分，其中包含来自父级的术语链接li，用于我创建的自定义分类法。

function add_custom_taxonomies() {
  // Add new "producttype" taxonomy to products
  register_taxonomy(\'producttype\', \'product\', array(
    // Hierarchical taxonomy (like categories)
    \'hierarchical\' => true,
    // This array of options controls the labels displayed in the WordPress Admin UI
    \'labels\' => array(
      \'name\' => _x( \'Producttypes\', \'taxonomy general name\' ),
      \'singular_name\' => _x( \'Producttype\', \'taxonomy singular name\' ),
      \'search_items\' =>  __( \'Search Producttypes\' ),
      \'all_items\' => __( \'All Producttypes\' ),
      \'parent_item\' => __( \'Parent Producttype\' ),
      \'parent_item_colon\' => __( \'Parent Producttype:\' ),
      \'edit_item\' => __( \'Edit Producttype\' ),
      \'update_item\' => __( \'Update Producttype\' ),
      \'add_new_item\' => __( \'Add New Producttype\' ),
      \'new_item_name\' => __( \'New Producttype Name\' ),
      \'menu_name\' => __( \'Product Type\' ),
    ),
    // Control the slugs used for this taxonomy
    \'rewrite\' => array(
      \'slug\' => \'Producttype\', // This controls the base slug that will display before each term
      \'with_front\' => false, // Don\'t display the category base before "/locations/"
      \'hierarchical\' => true // This will allow URL\'s like "/locations/boston/cambridge/"
    ),
  ));
}
add_action( \'init\', \'add_custom_taxonomies\', 0 );

我为分类法“producttype”创建了一个称为“Type”的父项，我只想获取父项“Type”下的那些子项，并将它们显示为链接。我在wordpress仪表板中手动创建了父术语。
