zf2 – Get the route name in a custom view helper

========================
IMPORTANT UPDATE: this is a very old post – find a better way in my post “zf2/zf3 – get the route name in a custom view helper”
========================

Ever tried to get the route name in your custom view helper in a zf2 (zend framework 2.1) project?
I searched a lot – until I realized that I have to call getServiceLocator on my serviceLocator instance 😉
This is the solution:

<?php
namespace YouCompany\YourNameSpace;

use Zend\ServiceManager\ServiceLocatorInterface;

use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\View\Helper\AbstractHelper;

class YourViewHelper extends AbstractHelper implements ServiceLocatorAwareInterface {

private $serviceLocator;

 public function __invoke() {
   $routeMatch = $this->serviceLocator->getServiceLocator()->get('Application')->getMvcEvent()->getRouteMatch();
   echo $routeMatch->getMatchedRouteName();
   die;
 }

 /**
 * Set service locator
 *
 * @param ServiceLocatorInterface $serviceLocator
 */
 public function setServiceLocator(ServiceLocatorInterface $serviceLocator) {
   $this->serviceLocator = $serviceLocator;
 }

 /**
 * Get service locator
 *
 * @return ServiceLocatorInterface
 */
 public function getServiceLocator() {
   return $this->serviceLocator;
 }
}
