我有一种情况，我想重定向用户从单一。php到我的404。php

我该怎么做？

我在单曲里就是这样做的。php

header("HTTP/1.0 404 Not Found");
header("Location: ".bloginfo(\'template_url\')."/404.php");
exit();

But when I check the http responses I get a 302 response instead of the 404

Important: it may not work because I have a post called "cars" which I use to custom generate pages like:

http://www.mysite.com/cars/bwm
http://www.mysite.com/cars/crysler

帖子只是：

http://www.mysite.com/cars/

其余的只是使用add\\u rewrite\\u规则重写的php查询字符串。所以

http://www.mysite.com/cars/?bmw

被重写为：

http://www.mysite.com/cars/bmw

有时变量bmw不在我的数据库中，我希望这个页面得到404响应。

header("HTTP/1.0 404 Not Found");
$wp_query->set_404(); //This will inform WordPress you have a 404 - not absolutely necessary here, but for reference only.
require \'/path/to/404.php\';
exit;
