令人惊讶的是，Wordpress并没有让它变得非常简单。尽管很多人在wordpress上都有类似的问题。org论坛，我相信你的论坛是独一无二的，因为你想保持秩序和排序。

这绝不是高质量的代码，但它完全符合您的要求。

class WP_Query_Custom extends WP_Query {
    static $filters = array( \'join\', \'groupby\', \'fields\', \'results\' );

    function get_posts() {
        $this->enable_filters();
        $posts = parent::get_posts();
        $this->disable_filters();
        return $posts;
    }

    function enable_filters() {
        foreach( self::$filters as $filter ) {
            add_filter( \'posts_\' . $filter, array( __CLASS__, \'filter_\' . $filter ), 10, 1 );
        }
    }

    function disable_filters() {
        foreach( self::$filters as $filter ) {
            remove_filter( \'posts_\' . $filter, array( __CLASS__, \'filter_\' . $filter ), 10, 1 );
        }
    }

    function filter_join($join) {
        global $wpdb;
        return "{$join} LEFT JOIN {$wpdb->posts} AS post_attachment ON {$wpdb->posts}.ID=post_attachment.post_parent AND post_attachment.post_type=\'attachment\' ";
    }

    function filter_groupby($groupby) {
        global $wpdb;
        if ( ! empty($groupby) ) {
            $groupby = ",$groupby";
        }
        return "{$wpdb->posts}.ID{$groupby}";
    }

    function filter_fields($fields) {
        $fields = "GROUP_CONCAT(post_attachment.ID) AS post_attachments, ".$fields;
        return $fields;
    }

    function filter_results($posts) {
        $num_posts = count($posts);
        $offset = 0;
