Set layout variables for use by the (404) error pages in ZF2

Question

At present I set a couple of variables to be used by the app\'s overall layout.phtml, using the onDispatch method of a BaseController, which all my other controllers extend:

Answer 1

Change the event you're listening for.

In this case, I'd move this logic to the application bootstrap event or the application render event (I haven't tested this, but it would probably work fine).

One example, in your Module.php

public function onBootstrap($e)
{
    $config = $e->getApplication()->getServiceManager()->get('config');
    //$e->getViewModel()->setVariable();
}

Haven't tested that commented out line, but it should get you headed in the right direction.

EDIT: Found an example of using the render event

public function onBootstrap($e)
{
    $event = $e->getApplication()->getEventManager();

    $event->attach('render', function($e) {
        $config = $e->getApplication()->getServiceManager()->get('config');
        $e->getViewModel()->setVariable('test', 'test');
    });
}

When using onDispatch in a Controller, remember to return the parent with the event and all:

public function onDispatch(MvcEvent $e)
{
    // Your code
    return parent::onDispatch($e);
}

Otherwise, the logic on your Actions in that Controller will be ignored.
