Cakephp - how to make error pages have its own layouts?

Question

I wanna have a different layout for the page not found 404 page. How can i set a different layout for that page?

Solution 1

Savant from the IRC helped me out and he suggest in using beforeRender(){} in the app_controller

// Before Render
function beforeRender() {
    if($this->name == 'CakeError') {
        //$this->layout = 'error';
    }
}

CakeError is a catchAll for errors :D

Solution 2

In CakePHP 2.2.2 I changed the ExceptionRenderer in core.php with my own, like this:

app/Config/core.php:

Configure::write('Exception', array(
  'handler' => 'ErrorHandler::handleException',
  'renderer' => 'MyExceptionRenderer', // this is ExceptionRenderer by default
  'log' => true
));

app/Lib/Error/MyExceptionRenderer.php:

App::uses('ExceptionRenderer', 'Error');

class MyExceptionRenderer extends ExceptionRenderer {

  protected function _outputMessage($template) {
    $this->controller->layout = 'error';
    parent::_outputMessage($template);
  }

}

Solution 3

Just you need to make layout changes in your error400.ctp file under /app/View/Errors/error400.ctp

Open that file and set layout by

<?php $this->layout=''; //set your layout here ?>

Solution 4

better to create an error.php file in your app folder

class AppError extends ErrorHandler { 
    function error404($params) { 
            $this->controller->layout = 'error'; 
            parent::error404($params); 
    } 
}

so you can avoid the if-testing at EVERY page render that savants' solution introduces

My solution for CakePHP 2.3

Change the ExceptionRenderer in core.php to use your own renderer.

app/Config/core.php:

Configure::write('Exception', array(
  'handler' => 'ErrorHandler::handleException',
  'renderer' => 'MyExceptionRenderer',
  'log' => true
));

app/Lib/Error/MyExceptionRenderer.php:

 App::uses('ExceptionRenderer', 'Error');

 class MyExceptionRenderer extends ExceptionRenderer 
 {
    /**
     * Overrided, to always use a bare controller.
     * 
     * @param Exception $exception The exception to get a controller for.
     * @return Controller
     */
    protected function _getController($exception) {
        if (!$request = Router::getRequest(true)) {
            $request = new CakeRequest();
        }
        $response = new CakeResponse(array('charset' => Configure::read('App.encoding')));
        $controller = new Controller($request, $response);
        $controller->viewPath = 'Errors';
        $controller->layout = 'error';
        return $controller;
    }
 }

The advantage to this approach is that it ensures any exceptions thrown from AppController don't cause an endless loop when rendering the exception. Forces a basic rendering of the exception message every time.

This method is no longer valid with CakePHP 2.x. And I have no idea how to do it now... lol

I don't confirm in Cake 2.2.1. I debug $this->layout inside beforeRender, I get the expected 'public_layout', but it is still rendered in default.ctp. DEBUG is set to 0.
