How to render ZF2 view within JSON response?

by

OK, i think i finally understood what you’re doing. I’ve found a solution that i think matches your criteria. Though i am sure that there is room for improvement, as there’s some nasty handwork to be done…

public function indexAction()
{
  if (!$this->getRequest()->isXmlHttpRequest()) {
    return array();
  }

  $htmlViewPart = new ViewModel();
  $htmlViewPart->setTerminal(true)
               ->setTemplate('module/controller/action')
               ->setVariables(array(
                  'key' => 'value'
               ));

  $htmlOutput = $this->getServiceLocator()
                     ->get('viewrenderer')
                     ->render($htmlViewPart);

  $jsonModel = new JsonModel();
  $jsonModel->setVariables(array(
    'html' => $htmlOutput,
    'jsonVar1' => 'jsonVal2',
    'jsonArray' => array(1,2,3,4,5,6)
  ));

  return $jsonModel;
}

As you can see, the templateMap i create is … nasty … it’s annoying and i’m sure it can be improved by quite a bit. It’s a working solution but just not a clean one. Maybe somehow one would be able to grab the, probably already instantiated, default PhpRenderer from the ServiceLocator with it’s template- and path-mapping and then it should be cleaner.

Thanks to the comment ot @DrBeza the work needed to be done could be reduced by a fair amount. Now, as I’d initially wanted, we will grab the viewrenderer with all the template mapping intact and simply render the ViewModel directly. The only important factor is that you need to specify the fully qualified template to render (e.g.: “$module/$controller/$action”)

I hope this will get you started though 😉

PS: Response looks like this:

Object:
    html: "<h1>Hello World</h1>"
    jsonArray: Array[6]
    jsonVar1: "jsonVal2"
