Custom 404 Page Examples
When an exception is thrown in your web application and it is not caught, you will typically see the result featuring the exception displayed in your browser window, as shown here: Rather than displaying the above default page when an exception occurs, you can redirect the user to a custom-written error page for a particular type of exception. You can do this via the error-page element 404 error page html code in web.xmlW, in which you can specify an exception-type and the location of the resource where a user should be sent if an error occurs. In this example, I specified the exception-type as java.lang.Throwable so that all exceptions would be sent to the error.jsp page.

An Improved Exception Handler 2. The Error Page Controller 3. Conclusion By default Kohana 3 doesn't have a method to display friendly error pages like that seen error page in Kohana 2; In this short guide you will learn how it is done. Prerequisites You will need 'errors' => TRUE passed to Kohana::init. This will convert PHP errors into exceptions which are easier to handle. 1. An Improved Exception Handler Our custom exception handler is self explanatory. class Kohana_Exception extends Kohana_Kohana_Exception { public static function handler(Exception $e) { if (Kohana::$environment === Kohana::DEVELOPMENT) { 404 error page parent::handler($e); } else { try { Kohana::$log->add(Log::ERROR, parent::text($e)); $params = array ( 'action' => 500, 'message' => rawurlencode($e->getMessage()) ); if ($e instanceof HTTP_Exception) { $params['action'] = $e->getCode(); } // Error sub-request. echo Request::factory(Route::get('error')->uri($params)) ->execute() ->send_headers() ->body(); } catch (Exception $e) { // Clean the output buffer if one exists ob_get_level() and ob_clean(); // Display the exception text echo parent::text($e); // Exit with an error status exit(1); } } } } If we are in the development environment then pass it off to Kohana otherwise: Log the error Set the route action and message attributes. If a HTTP_Exception was thrown, then override the action with the error code. Fire off an internal sub-request. The action will be used as the HTTP response code. By default this is: 500 (internal server error) unless a HTTP_Response_Exception was thrown. So this: throw new HTTP_Exception_404(':file does not exist', array(':file' => 'Gaia')); would display a nice 404 error page, where: throw new Kohana_Exception('Directory :dir must be writable', array(':dir' => Debug::path(Kohana::$cache_dir))); would display an error 500 page. The Route Route::set('error', 'error/

Prerequisites You will need 'errors' => TRUE passed to Kohana::init. This will convert PHP-errors into exceptions which are easier to handle (The default value is TRUE). Custom error pages will only be used to handle throw HTTP_Exception's. If you simply set a status of, for example, 404 via Respose::status the custom page will not be used. Extending the HTTP_Exception classes Handling HTTP_Exception's in Kohana has become easier with the changes introduced in 3.3. For each HTTP_Exception class we can individually override the generation of the Response instance. Note: We can also use HMVC to issue a sub-request to another page rather than generating the Response in the HTTP_Exception itself. For example, to handle 404 pages we can do this in APPPATH/classes/HTTP/Exception/404.php: class HTTP_Exception_404 extends Kohana_HTTP_Exception_404 { /** * Generate a Response for the 404 Exception. * * The user should be shown a nice 404 page. * * @return Response */ public function get_response() { $view = View::factory('errors/404'); // Remembering that `$this` is an instance of HTTP_Exception_404 $view->message = $this->getMessage(); $response = Response::factory() ->status(404) ->body($view->render()); return $response; } } Another example, this time to handle 401 Unauthorized errors (aka "Not Logged In") we can do this in APPPATH/classes/HTTP/Exceptio
