在Kohana中，您可以触发404错误吗? [英] In Kohana, can you trigger a 404 error?

问题描述

我有一个名为articles的控制器，该控制器创建商品模型，该模型从数据库中获取相关数据.

I have a controller called articles, which creates the articles model which gets the relevant data from the database.

如果调用的方法返回false，我想触发404错误.这就是我到目前为止所拥有的.

I want to, if the method I call returns false, to trigger a 404 error. This is what I have so far.

 $articleName =  $this->uri->segment('articles');

 $article = new Articles_Model();

 $data = $article->getArticleUsingSlug($articleName);

 if (!$data) {
    Kohana::show_404; // This doesn't work.
 }

我刚刚添加了自己的自定义钩子，该钩子将用户重定向到由Kohana触发的实际404(/articles/page-not-found/)，但是有一种方法可以调用其内部的404方法来使Kohana提供处理我的控制器并使用我的新钩子?

I just added my own custom hook which redirects the user to an actual 404 (/articles/page-not-found/) as triggered by Kohana, but is there a way I can invoke its internal 404 method to make Kohana give up processing my controller and use my new hook ?

推荐答案

这对我有用:

Event::run('system.404');

您使用的Kohana是哪个版本?

What version of Kohana are you using?
