Php WordPress-仅显示（自定义）标记的帖子

我目前正在构建一个基于templatic events v2主题的网站。我做了一些定制工作，效果很好，但这一项是我力所能及的

问题如下

我需要建立一个小部件，它只输出标记为特色的事件（自定义帖子）。现在我有一些不同的方式来显示事件，但它们基本上只是按类别或日期排序

示例站点：

以下是我正在使用的小部件的当前代码：

    class blaestfeatured extends WP_Widget {
    function blaestfeatured() {
    //Constructor
        $widget_ops = array('classname' => 'widget category List View', 'description' => 'Custom Featured event widget by Christoffer Sandstrøm' );
        $this->WP_Widget('blaestfeatured', 'blaestfeatured', $widget_ops);
    }

    function widget($args, $instance) {
    // prints the widget

        extract($args, EXTR_SKIP);
        echo $before_widget;
        $widget_id= $args['widget_id'];
        $title = empty($instance['title']) ? '' : apply_filters('widget_title', $instance['title']);
        $category = empty($instance['category']) ? '' : apply_filters('widget_category', $instance['category']);
        $post_number = empty($instance['post_number']) ? '5' : apply_filters('widget_post_number', $instance['post_number']);
        $post_link = empty($instance['post_link']) ? '' : apply_filters('widget_post_link', $instance['post_link']);
        $more_link = empty($instance['more_link']) ? '' : apply_filters('widget_more_link', $instance['more_link']);
        $character_cout = empty($instance['character_cout']) ? '15' : apply_filters('widget_character_cout', $instance['character_cout']);
        $sorting = empty($instance['event_sorting']) ? 'Latest Published' : apply_filters('widget_event_sorting', $instance['event_sorting']);
         ?>
          <h3 class=""><?php echo $title; ?> </h3>

回答得很好，虽然使用元查询时不需要使用“meta_key”
。非常感谢！我知道这又是一个相当迟钝的问题，但我如何使用它来输出它？我尝试在这里搜索一些，但没有多大意义：/Thank you！我无法运行它，可能是因为我怀疑的其他代码t、 请参阅我的新回复@Banago最终使其不崩溃并输出一些内容，但它仍然只打印前五个事件：/
