How do you include the javascript helper in the ErrorHanlder? - php

Question

I have this custom error handler:
`class AppError extends ErrorHandler {
function error404($params) {
$this->controller->layout = 'public';
$this->controller->set('title','Droptor Page Not Found');
parent::error404($params);
}
}`
And I can't seem to use any layout that has this:
$javascript->link('jquery',true)
So the JS helper isn't loaded. But if I include this in the controller: var $helpers = array('javascript'); it still doesn't work. Nor does App::import('Helper', 'javascript');

Answer 1

Crap, I didn't read your question.
To add a helper to your error controller, just add this line:
$this->controller->helpers = array('Javascript');
There are two ways to do it:
First, you can create an app_controller to include every component and helper that you need on all your controllers.
Second, you can load the specific resources needed to your error controller. Create a file named error.php in your app's root (NOT webroot) with the following code:
<?php
class AppError extends ErrorHandler {
function error404($params) {
$this->controller->helpers = array('Javascript');
parent::error404($params);
}
}
You can also set a custom title with
$this->controller->set('title_for_layout', "We couldn't find what you are loooking for");
Good luck.

First off, you don't need to create your own handler if all you're doing is handling a common error type, such as 404. Custom error handlers are for your application specific errors.
If you want to simply change the layout of your page when you get a 404 error, this has been answered over here.
function beforeRender() {
if($this->name == 'CakeError') {
$this->layout = false;
}
}
And you can cause it using the line:
$this->cakeError('error404');
