我正在使用这里描述的技术Seperating Custom Post Search Results 还有这里posts_groupby problem 将我的搜索结果分开并按帖子类型分组。这意味着我有以下代码。

In functions.php

add_filter(\'posts_orderby\', \'group_by_post_type\', 10, 2);
function group_by_post_type($orderby, $query) {
    global $wpdb;
    if ($query->is_search) {
        return $wpdb->posts . \'.post_type DESC\';
    }
    // provide a default fallback return if the above condition is not true
    return $orderby;
}

In search.php

<?php $last_type="";
$typecount = 0;
while (have_posts()){
    the_post();
    if ($last_type != $post->post_type){
        $typecount = $typecount + 1;
        if ($typecount > 1){
            echo \'</ol>\'; //close type container
        }
        // save the post type.
        $last_type = $post->post_type;
        //open type container
        switch ($post->post_type) {
            case \'post\':
                echo "<h2>News Articles</h2><ol>";
                break;
            case \'page\':
                echo "<h2>Pages</h2><ol>";
                break;
            case \'work\':
                echo "<h2>Projects</h2><ol>";
                break;
            case \'bootlegs\':
                echo "<h2>Bootlegs</h2><ol>";
                break;
            case \'directors\':
                echo "<h2>Directors</h2><ol>";
                break;
            //add as many as you need.
        }
    } ?>

除了我无法控制自定义帖子类型的显示顺序之外，这一切都非常有效。我猜它们是通过内部ID号订购的，但我需要控制它们。

我怎样才能做到这一点？

谢谢

if ($query->is_search) {
    return $wpdb->posts . \'.post_type DESC, title DESC\';
}

add_filter( \'pre_get_posts\', \'ordering_post_title_type\');
function ordering_post_title( $query ) {

    if ( $query->is_search ) {
        $query->set(\'orderby\',\'type title\');
        $query->set(\'order\',\'ASC\');
    }

    return $query;

}
