我正在处理Codeigniter项目,如果找不到路由,我想显示自定义404页面。一切都在localhost上工作正常,但是当我在实时服务器上传我的项目时,它不再显示了。在实时服务器上它显示我默认404.并且url生成如下example.com/my404但不显示我的自定义404.请帮助我找出我遗漏的地方。谢谢你有价值的答案。
这是我的查看文件error_404.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>404 Page Not Found</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">

<h1 class="web">Go back to <a href="<?php echo base_url();?>"><span>www.vpacknmove.in</span></a><h1>
</div>
</body>
</html>
这是我的Controller文件My404.php
<?php
class My404 extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->output->set_status_header('404');
$this->load->view('error_404');//loading in my template
}
}
?>
我的路线
$route['404_override'] = 'My404';
$route['default_controller'] = 'Home';
答案 0 :(得分:1)
尝试在路线中小写控制器名称:
$route['404_override'] = 'my404';
如果这不能解决您的问题,请回报。
如果您需要自定义在没有匹配路由时生成的404,该怎么办,我创建了一个文件/application/core/MY_Exception.php:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Exceptions extends CI_Exceptions {
/**
* Class constructor
*/
public function __construct()
{
parent::__construct();
}
// --------------------------------------------------------------------
/**
* 404 Error Handler
* -----------------
* This method has been extended so that if we use the show_404
* function, that it is a styled/custom 404 page that is shown.
*/
public function show_404( $page = '', $log_error = TRUE )
{
if( is_cli() )
{
$heading = 'Not Found';
$message = 'The controller/method pair you requested was not found.';
}
else
{
$heading = '404 Error - Page Not Found';
$message = 'The page or resource you were looking for was not found on this server.';
}
// By default we log this, but allow a dev to skip it
if( $log_error )
{
log_message('error', $heading . ': ' . $page );
}
if( is_cli() )
{
echo $this->show_error($heading, $message, 'error_404', 404);
}
else
{
$CI = &get_instance();
$CI->output->set_status_header('404');
$view_data = [
'heading' => $heading,
'message' => $message
];
$data = [
'doc_title' => ['pre' => '404 Error - Page Not Found - '],
'extra_head' => '<meta name="robots" content="noindex,nofollow" />',
'content' => $CI->load->view( 'errors/html/error_404', $view_data, TRUE )
];
$CI->load->view('templates/main', $data);
echo $CI->output->get_output();
}
exit(4); // EXIT_UNKNOWN_FILE
}
// --------------------------------------------------------------------
}
请注意我完成它的方式,我将error_404视图嵌套在我创建的模板中。这就是我这样做的方式。您在应用程序(通常是控制器)中创建页面时使用的内容替换了该部分。
