php – CakePHP 2.0 – How to make custom error pages?

Posted by: admin April 23, 2020 Leave a comment


I read that the AppError class is now for backwards compatibility and that Exceptions should be used instead. How does one go about creating custom error pages for things like 404 errors, or completely custom errors?

How to&Answers:

Try this:


Exception render need to set as an AppExceptionRender. Example:

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


class ErrorsController extends AppController {
    public $name = 'Errors';

    public function beforeFilter() {

    public function error404() {
        //$this->layout = 'default';


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

class AppExceptionRenderer extends ExceptionRenderer {

    public function notFound($error) {
        $this->controller->redirect(array('controller' => 'errors', 'action' => 'error404'));


<div class="inner404">
    <h2>404 Error - Page Not Found</h2>

Insert it where you need: throw new NotFoundException();


To customize the content of a 404-error page and don’t need custom logic, simply edit the contents of app/View/Errors/error400.ctp.

This seems not to be documented properly anywhere.


If you’re only looking to use another layout instead of the default, just add $this->layout = 'your_error_layout'; inside your error400.ctp (or any other error page you create under View/Errors).


Create a layout with name 404 or anything and use in app controller

function _setErrorLayout() {
    if ($this->name == 'CakeError') { 
        $this->layout = '404';
function beforeRender () {


The accepted answer is not the best option because they redirect the url of your browser to http://example.com.br/error/error404 and the user can’t follow what page he inputed to generate this error.

The better way to handle this situation is edit file on View/Errors/error400.ctp, so when you input a not found url like http:example.com/crazy-wrong-url, the browser will keep this url but render the content of the error400.ctp file that you edit.

If you want change the layout that the view will be rendered you can type this in your view <?php $this->layout = 'error'; ?>


You can create CustomErrorPages or Exeptions by simply creating a class of your error your going to show. This class needs to extend CakeExeption. Then build your exeptionlogic and your set. Now you can just throw new <YourExeptionClass>() and it will display an error.

Documentation: CakeExceptions


Had discovered today that is possible to get excpetion code in ctp file using $error->getCode() (in CakePHP 2.x, at least).

The $error is were Cake puts the exception object…

Now you should be able to change the content of your view with an if/else conditional block, based in this value.
