        如果您使用'taxonomies' => array('category', 'post_tag')然后wordpress默认帖子的标签将显示在自定义帖子类型区域.
这是"新闻"帖子类型的干净而独特的方式.不与其他自定义帖子类型,默认标签,等等混合.
您可以通过此链接关注"使用类别创建自定义帖子类型和标签"的完整详细信息.
add_action( 'init', 'news_tag_taxonomies' ); //change order add_action( 'init', 'news_tag_taxonomies', 0 );
//create two taxonomies, genres and tags for the post type "tag"
function news_tag_taxonomies() 
{
  // Add new taxonomy, NOT hierarchical (like tags)
