如何从侧边栏中获取单页自定义帖子类型的帖子以显示在页面中？

Question

我有一个名为storylist的自定义帖子类型，它是作为侧边栏小部件的插件完成的。自定义帖子类型的故事列表编译其他自定义帖子类型的列表，并在侧边栏中显示它们。帖子在侧边栏中显示的方式相同，我需要有相同的列表，在这种情况下是＃34;热门话题＆＃34;当＆＃34;查看更多＆＃34;时显示在页面上单击按钮。我得到的最好的是所有故事列表帖子的存档，但当你点击它们时，如热门话题，它会带你到网址http://site/storylist/hot-topics，这是正确的网址，但它是空白的，仅显示页面标题。关于如何发布这些帖子的任何建议都出现在热门话题上？

以下是使其显示在窗口小部件中的代码：

    $instance['storylist_id_1'] = isset($new_instance['storylist_id_1']) ? (int)$new_instance['storylist_id_1'] : 0;
    $instance['storylist_id_2'] = isset($new_instance['storylist_id_2']) ? (int)$new_instance['storylist_id_2'] : 0;

    $instance['n'] = isset($new_instance['n']) ? (int)$new_instance['n'] : 4;

    return $instance;
   }
 }

  add_action( 'widgets_init', function(){ register_widget( 'ChemTabs' ); });

有什么办法可以让页面模板显示页面ID吗？我试图这样做，但它没有显示任何东西。

Answer 1

我通过添加此代码$list_args2 = array( "post_type" => "any", "post__in" => get_post_meta( 210639, 'storylist', true), "orderby" => "post__in", 'post_status' => 'publish' );
