ZF2 Cheat Sheet

Because I always forget everything I'm told in #zftalk.2

Controller Stuff

Access querystring parameter:

$this->params()->fromQuery('foo');

Check if querystring parameter exists:

null !== $this->params()->fromQuery('foo', null);

Get a parameter from the route

$slug = $this->params('slug');

Set a different view script:

$viewModel = new ViewModel();
$viewModel->setTemplate('module/controller/viewscript.phtml');

Get action from controller:

$this->getEvent()->getRouteMatch();

or

$this->params('action');

Disable layout in a ViewModel:

$viewModel = new ViewModel();
$viewModel->setTerminal(true);

Disable view rendering from an action:

return $this->response;

Set custom headers or response code:

/** @var \Zend\Http\PhpEnvironment\Response $response  */
$response = $this->getResponse();
/** 404 Not Found page return magically */
$response->setStatusCode(404);
/** Set custom response headder */
$headers = $response->getHeaders();
$headers->addHeaderLine('My-Custom-Header', 'ZF2');

#Module Stuff

Change controller in Module.php:

$controller = $e->getTarget();
$controller->layout('layout/alternativelayout');
