找不到codeigniter 3.0自定义404错误页面 [英] codeigniter 3.0 custom 404 not found error page

问题描述

我的问题是关于升级到Codeigniter 3.0之后的自定义错误页面.

My problem is about custom error pages after upgrading to Codeigniter 3.0.

我以前有一个Errors控制器，用于处理网站的404错误页面-在该控制器上，我自定义了页面的某些部分，例如，如果用户登录，在导航栏上显示用户名等.(是，在404错误页面上).

I used to have a Errors controller which handled 404 error page of the website - on this controller I have customized some parts of page, such as if user is logged in, it was showing username on the navigation bar and etc. (yes, on 404 error page).

升级到CI 3.0后，我注意到错误页面在其他文件夹中处理，我开始迁移到这种方式.但是问题是我无法在此页面上加载任何变量，例如会话变量，甚至无法在这些页面上使用任何CI的功能.

After upgrading to CI 3.0, I have noticed that error pages are handled in different folder, I started to migrate to this way; but the problem is I can't load any variables to this page, such as session variables or can't even use any CI's functions on these pages.

我认为该页面应该只是HTML页面，但是有什么方法可以将变量加载到这些错误页面上?

I think this pages are supposed to be only HTML pages, but is there any way to load variables to these error pages?

推荐答案

您需要在application/config/routes.php中设置以下路线

You need to set in application/config/routes.php the following route

$route['404_override'] = 'my404';

然后您需要在controllers目录(application/controllers/)

Then you need to create a new controller in your controllers directory (application/controllers/)

<?php 
class My404 extends CI_Controller 
{
 public function __construct() 
 {
    parent::__construct(); 
 } 

 public function index() 
 { 
    $this->output->set_status_header('404'); 
    $this->load->view('err404');//loading in custom error view
 } 
} 

并创建一个err404视图.就是这样！

And create an err404 view. Thats all!
