Answer 1

Since v3.1 the Kohana guide incldues a tutorial on custom error pages which show a much cleaner way of solving this question.

Answer 2

All you need to do is set the path to a different view in your bootstrap.php add:

Kohana_Exception::$error_view = 'error/myErrorPage';

that will parse all the variables currently being parsed to the error page that lives in:

system/views/kohana/error.php

ie:

<h1>Oops [ <?= $code ?> ]</h1>
<span class="message"><?= html::chars($message) ?></span>

Answer 3

Replace the last line of bootstrap.php with:

/**
* Set the production status
*/
define('IN_PRODUCTION', FALSE);

/**
* Execute the main request. A source of the URI can be passed, eg: $_SERVER['PATH_INFO'].
* If no source is specified, the URI will be automatically detected.
*/
$request = Request::instance();

try
{
    $request->execute();
}
catch (Kohana_Exception404 $e)
{
    $request = Request::factory('error/404')->execute();
}
catch (Kohana_Exception403 $e)
{
    $request = Request::factory('error/403')->execute();
}
catch (ReflectionException $e)
{
    $request = Request::factory('error/404')->execute();
}
catch (Kohana_Request_Exception $e)
{
    $request = Request::factory('error/404')->execute();
}
catch (Exception $e)
{
    if ( ! IN_PRODUCTION )
    {
        throw $e;
    }

    $request = Request::factory('error/500')->execute();
}

echo $request->send_headers()->response;

Create new controller "error.php":

<?php defined('SYSPATH') or die('No direct script access.');

class Controller_Error extends Controller {

    public function action_404()
    {
        $this->request->status = 404;
        $this->request->headers['HTTP/1.1'] = '404';
        $this->request->response = 'error 404';
    }

    public function action_403()
    {
        $this->request->status = 403;
        $this->request->headers['HTTP/1.1'] = '403';
        $this->request->response = 'error 403';
    }

    public function action_500()
    {
        $this->request->status = 500;
        $this->request->headers['HTTP/1.1'] = '500';
        $this->request->response = 'error 500';
    }
} // End Error

Create two files (exception404.php и exception403.php) in "kohana" folder:

<?php defined('SYSPATH') or die('No direct access');

class Kohana_Exception403 extends Kohana_Exception {

    public function __construct($message = 'error 403', array $variables = NULL, $code = 0)
    {
        parent::__construct($message, $variables, $code);
    }

} // End Kohana_Exception 403


<?php defined('SYSPATH') or die('No direct access');

class Kohana_Exception404 extends Kohana_Exception {

    public function __construct($message = 'error 404', array $variables = NULL, $code = 0)
    {
        parent::__construct($message, $variables, $code);
    }

} // End Kohana_Exception 404

Now you can manually throw 404 and 403 errors (you can't throw error 500 ;)

throw new Kohana_Exception404;
throw new Kohana_Exception403;
