我正在我的网站上工作，并在wp\\u查询中使用这些参数，但我也想只显示那些有缩略图的帖子。。。以下是我正在处理的参数：

        $args1 = array(
            \'posts_per_page\'        => $number,
            \'no_found_rows\'         => true,
            \'post_status\'           => \'publish\',
            \'offset\'                => $offset,
            \'ignore_sticky_posts\'   => true,
            \'orderby\'               => $sort_order,
            \'meta_key\'              => ( ($sort_order == \'meta_value_num\') ? \'mip_post_views_count\' : \'\' )
        );

        $args2  = array();
        if ($include_categories) {
            //$include_categories = explode(",", $include_categories);
            $args2 = array(
                \'cat\'      => $include_categories
            );
        } 

    $args1 = array(
            \'posts_per_page\'        => $number,
            \'no_found_rows\'         => true,
            \'post_status\'           => \'publish\',
            \'offset\'                => $offset,
            \'ignore_sticky_posts\'   => true,
            \'orderby\'               => $sort_order,
            \'meta_key\'              => ( ($sort_order == \'meta_value_num\') ? \'mip_post_views_count\' : \'\' ),
            // this is what is added
            \'meta_query\'    => \'_thumnail_id\'
        );

        $args2  = array();
        if ($include_categories) {
            //$include_categories = explode(",", $include_categories);
            $args2 = array(
                \'cat\'      => $include_categories
            );
        }
