I am trying to create a JsonModel with an item in the variables 'html' containing the current rendered view. I would like to add this code to an event: rather than this method: How to render ZF2 view within JSON response? which is in the controller, I would like to automate the process by moving it to an Event
I have the strategy in my module.config.php:
'strategies' => array(
'ViewJsonStrategy',
)
I have set up a setEventManager in the controller:
$events->attach(MvcEvent::EVENT_RENDER, function ($e) use ($controller) {
$controller->setRenderFormat($e);
}, -20);
Is this the best event to attach it to? would the RENDER_EVENT be better?
Now I would like to change the render of the page based on !$this->getRequest()->isXmlHttpRequest(), (commented out for debug)
public function setRenderFormat($e)
{
//if(!$this->getRequest()->isXmlHttpRequest())
//{
$controller = $e->getTarget();
$controllerClass = get_class($controller);
//Get routing info
$controllerArr = explode('\\', $controllerClass);
$currentRoute = array(
'module' => strtolower($controllerArr[0]),
'controller' => strtolower(str_replace("Controller", "", $controllerArr[2])),
'action' => strtolower($controller->getEvent()->getRouteMatch()->getParam('action'))
);
$view_template = implode('/',$currentRoute);
$viewmodel = new \Zend\View\Model\ViewModel();
$viewmodel->setTemplate($view_template);
$htmlOutput = $this->getServiceLocator()->get('viewrenderer')->render($viewmodel, $viewmodel);
$jsonModel = new JsonModel();
$jsonModel->setVariables(array(
'html' => $htmlOutput,
'jsonVar1' => 'jsonVal2',
'jsonArray' => array(1,2,3,4,5,6)
));
return $jsonModel;
//}
}
Strangely, (or not) this code works and produces the $jsonModel, however is doesn't overwite the normal HTML view with the json, but the same code (without the event) in a controller method, overwrites perfectly.
p.s Is there a better method to do the whole concept?
p.p.s how can I obtain the current View Template from within the controller, without resorting to 8 lines of code?
Thanks in advance!

you are returning the view model from an event I thinks this doesn't have any effect in current viewmanager view model, fetch the current viewmodel from viewmanager and call setTerminal(true). or replace the created jsonmodel using the viewmanager
