我正在开发一个有展厅的汽车网站。每个展厅都需要基于其位置的自定义URL。位置（城市和县/州）已作为两个自定义字段插入。例如，如果是位于默西塞德郡利物浦的“展厅A”，其URL如下：-

http://www.domain.com/location/merseyside/liverpool/showroom-a/

我有一个自定义的post类型“Showroom”，它的重写规则设置为false（尽管之前在测试中设置为true）。然而，当我创建有问题的帖子时，出现了一个问题。permalink是指除展厅名称以外的所有内容（即。http://www.domain.com/location/merseyside/liverpool/). 访问此URL会导致404错误，甚至会在代码末尾添加“showroom-a”（例如）(http://www.domain.com/location/merseyside/liverpool/showroom-a/), 也会导致404错误。这是我的密码。

function add_rewrite_rules()
{
    // Register custom rewrite rules

    global $wp_rewrite;

    $wp_rewrite->add_rewrite_tag(\'%showroom%\', \'([^/]+)\', \'showroom=\');
    $wp_rewrite->add_rewrite_tag(\'%post_custom_data%\', \'([^/]+)\', \'post_custom_data=\');
    $wp_rewrite->add_permastruct(\'showroom\', \'location/%post_custom_data%\', false);

}

function permalinks($permalink, $post, $leavename)
{
    $no_data = \'no-data\';
    $post_id = $post->ID;

    if($post->post_type != \'showroom\' || empty($permalink) || in_array($post->post_status, array(\'draft\', \'pending\', \'auto-draft\'))) {
        return $permalink;
    }

    $state = sanitize_title_with_dashes(get_post_meta($post_id, \'state\', true));
    $city =  sanitize_title_with_dashes(get_post_meta($post_id, \'city\', true));
    $data = $state . "/" . $city;

    if (!$data) {
        $data = $no_data;
    }

    $permalink = str_replace(\'%post_custom_data%\', $data, $permalink);

    return $permalink;    
}

add_action(\'init\', \'add_rewrite_rules\');
add_filter(\'post_type_link\', \'permalinks\', 10, 3);

任何想法或帮助都将不胜感激：）

$wp_rewrite->add_permastruct(\'showroom\', \'location/%state%/%city%/%showroom%\', false);

$permalink = str_replace(\'%state%\', $state, $permalink);
$permalink = str_replace(\'%city%\', $city, $permalink);
