2.2 ErrorController
Error Controller
When SuitUp found some error Exception it's thrown firstly the ErrorController on the current module, if this does not exist SuitUp throw the default ErrorController in src/ModuleError/Controllers/ErrorController.php. Implement your own ErrorController for each module allows you to personalize your system error pages.
How to do?
- Create the controller class with the reserved name
ErrorController inside controllers folder on the module;
- Create the view
ModuleDefault/views/error/error.phtml for general errors;
- Create the view
ModuleDefault/views/error/not-found.phtml for not found errors;
- This error is launched if module, controller, action or view is not found.
Controller
Just create a controller with the reserved name ErrorController which extends AbstractController or MvcAbstractController, in this file you don't need to create any method, but you can override the init one to define a different layout for errors. You can too override the methods errorAction and notFoundAction if want, for example, create a system log before dispatch the view.

// File: ModuleDefault/Controllers/ErrorController.php
namespace ModuleDefault\Controllers;
class ErrorController extends AbstractController
{
public function init() {
// With this line the system will use this file as specific error layout instead of current module layout.
// Of course that for this the file `ModuleDefault/views/error/layout.phtml` must to exist.
$this->setLayout("error/layout.phtml");
}
}

Views
Obviously errors control are very important in the system to menage what is working and don't, so we made this easy way to follow errors on SuitUp. Otherwise don't make sense to show it as exceptions to the user, which it's a security failure so we use if DEVELOPMENT in the view. This prevents that the Exception description is shown to the user when system aren't in development environment.
Automatically the variable $exception will be available on the view with all information about the error occurred.
Follow the tip to the HTML for these errors page.
