我需要page id在循环外的WordPress插件页面中获取当前信息.我为获取最新信息而编写的代码page id在我的插件页面中.我尝试了很多代码,但是没有用

$page_object = get_queried_object();
$page_id     = get_queried_object_id();


 // "Dirty" pre 3.1
 global $wp_query;

$page_object = $wp_query->get_queried_object();
$page_id     = $wp_query->get_queried_object_id();

但它对我不起作用.

  global $post;
  echo "pageid: ".$post->ID;

这也行不通.

当我尝试

     global $wp_query;
     $post_obj = $wp_query->get_queried_object();
     $Page_ID = $post_obj->ID;
     echo $Page_ID;

然后会出现一条错误消息

致命错误:在第876行的H:\ xampp\htdocs\wordpress\wp-content\plugins\wpk\wpk.php中的非对象上调用成员函数get_queried_object()

当我打印:

global $wp_query;
print_r($wp_query);

然后结果是:

WP_Query Object

    [query] => 
    [query_vars] => Array
        (
        )

    [tax_query] =>
