codeigniter - show_404() 中的自定义 View 不起作用

Question

我已经尝试了 404_override 和 MY_Exceptions 来显示自定义错误 View 。有人可以帮我吗？

这是 404_override 代码

路由.php

$route['404_override'] = 'error/index';

错误.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Error extends CI_Controller {

    public $user_id ='';

    function __construct()
    {
        parent::__construct();
        $this->load->library('login.php');
        $user_Details = $this->login_library->get_user_details();
        $this->user_id = $user_Details['user_id'];
    }

    public function index()
    {
        $this->output->set_status_header('404');
         $this->output->set_status_header('404');  
        $this->load->view('view_header',$this->user_id); 
        $this->load->view('view_404');
        $this->load->view('view_footer',$this->user_id);     
    }



}

这是 My_Exceptions 代码

<?php  if (! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Exceptions extends CI_Exceptions{

    function MY_Exceptions(){
        parent::CI_Exceptions();
        $this->CI =& get_instance();
    }

    function show_404($page=''){ 
        echo $heading = "404 Page Not Found";
        echo $message = "The ppage you requested was not found.";
        $this->config =& get_config();
        $baseUrl = $this->config['base_url'];
        header("location: ".$baseUrl.'error.html');
        exit;
    }

}

我从这个链接得到了解决方案 - CodeIgniter 2.1 issue with show_404() and 404_override .

<?php
// application/core/MY_Exceptions.php
class MY_Exceptions extends CI_Exceptions {

    public function show_404()
    {
        $CI =& get_instance();
        $CI->load->view('my_notfound_view');
        echo $CI->output->get_output();
        exit;
    }
}

非常感谢所有的帮助。赞赏:)
