Set page title when handling errors in CakePHP - cakephp

Question

I need to change page title from default "Error" when handling errors like 404. So I need to put my the title in the variable $title_for_layout for my Layout. I tried to create custom error handling function by changing configuration in app/Config/core.php and setting the page title as in controllers
Configure::write('Error.handler', function($code, $description, $file = null, $line = null, $context = null) {
$this->set('title_for_layout', 'Vyskytla sa chyba');
});
As I expected, I got a PHP error (line 59 is the second line in the code sample)
Fatal error: Using $this when not in object context in /var/www/web/app/Config/core.php on line 59
So how I can set the title for my default.ctp layout?
Thanks.

In CakePHP 2.0, you can try the following code to achieve the same you needed.
Try this:
/app/Config/core.php
Exception render need to set as an AppExceptionRender. Example:
Configure::write('Exception', array(
'handler' => 'ErrorHandler::handleException',
'renderer' => 'AppExceptionRenderer',
'log' => true
));
/app/Controller/ErrorsController.php
class ErrorsController extends AppController {
public $name = 'Errors';
public function beforeFilter() {
parent::beforeFilter();
$this->Auth->allow('error404');
}
public function error404() {
//$this->layout = 'default';
$this->set('title_for_layout', 'Vyskytla sa chyba');
}
}
/app/Lib/Error/AppExceptionRenderer.php
App::uses('ExceptionRenderer', 'Error');
class AppExceptionRenderer extends ExceptionRenderer {
public function notFound($error) {
$this->controller->redirect(array('controller' => 'errors', 'action' => 'error404'));
}
}
/app/View/Errors/error404.ctp
<div class="inner404">
<h2>404 Error - Page Not Found</h2>
</div>
Insert it where you need: throw new NotFoundException();
Ref: CakePHP 2.0 - How to make custom error pages?
For < CakePHP 2.x:
If you create a custome error page view in app/views/errors then in a
php section on that error view page you can use:
$this->setLayout("Title for the error page here");
Then when you see the error page, it will have your title. Again, that
is if you set a custom error page.
Here is another way to do the same you needed.
// Create an error.php file in your /app folder with the following code:
<?php
class AppError extends ErrorHandler {
function error404($params) {
$this->controller->layout = "error";
$this->set('title_for_layout', 'Vyskytla sa chyba');
parent::error404($params);
}
}
?>
