我尝试使用以下模式显示快捷码：

    class callShortCode {


    function __construct() {
    global $post;
    $this->dos($post);
    }


    private function dos($post){
    global $post;
    $pid = get_the_ID();
    $archive_id = get_queried_object_id();

    if($archive_id == $pid) {
    add_action(\'wp_footer\', array($this, \'show\'));
    }

    }


    // shortcode call
    function show($post) {

    $pid = get_the_ID();
    $archive_id = get_queried_object_id();


    $the_query = new WP_Query( array(\'post_type\' => \'custom_post_type\') );
                    if ($the_query->have_posts()) {
                        while ($the_query->have_posts()){
                        $the_query->the_post();
                          if($pid == $archive_id) {
                            echo do_shortcode("[my_shortcode id=\'5\']");
                          }
                        }
                    }

    }

    }

new callShortCode();

但它在前端返回如下错误：

Fatal error: Call to a member function get_queried_object_id() on a non-object in D:\\xxxx\\xxxx\\xxxxx\\wp-includes\\query.php on line xx

我试着用init 操作，但它不希望读取前端上的当前页面id而不显示任何内容。我已经检查过$pid = get_the_ID(); 和$archive_id = get_queried_object_id(); 使用时返回0init 钩子调用对象。

我还用plugins_loaded 但它返回的是相同的致命错误！

我知道这是因为它叫得太早了！但是我该怎么做才能使它正常工作呢？

function wpse_177056_init_shortcode() {
    new callShortCode();
}

add_action( \'template_redirect\', \'wpse_177056_init_shortcode\' );

class callShortCode {

    function __construct() {
        $this->dos();
    }

  function dos() {
        $archive_id = get_queried_object_id();
        //Replace with your logic
        if( $archive_id === 451) {
            $this->show();
        }
   }

   // shortcode call
   function show() {

      $the_query = new WP_Query( array(\'post_type\' => \'custom_post_type\') );
      if ($the_query->have_posts()) {
          while ($the_query->have_posts()){
              $the_query->the_post();
                   echo do_shortcode("[my_shortcode id=\'5\']");
           }
       }

      wp_reset_postdata();

   }
}

add_action( \'wp_footer\', function() {
    new callShortCode;
});
