To do this the proper ZF2 way you should write a custom view helper.
You can call this view helper for example RouteMatchHelper.
Then in the view you can simply do $this->routeMatchHelper();
<?php
namespace Application\View\Helper;
use Zend\Mvc\Router\RouteMatch;
use Zend\View\Helper\AbstractHelper;
class RouteMatchHelper extends AbstractHelper
{
/**
* #var RouteMatch
*/
protected $routeMatch;
/**
* Constructor with dependency
*
* #param RouteMatch $routeMatch
*/
public function __construct(RouteMatch $routeMatch)
{
$this->routeMatch = $routeMatch;
}
public function __invoke()
{
$controller = $this->routeMatch->getParam('controller');
$action = $this->routeMatch->getParam('action');
return sprintf(
"the action is %s and the controller name is %s",
$action,
$controller
);
}
}
You need RouteMatch in your view helper so you have to setup a factory. You will have to register the factory under the view_helpers key in your module.config.php file:
'view_helpers' => array(
'factories' => array(
'routeMatchHelper' => `Application\View\Helper\RouteMatchHelperFactory`
)
)
And then the factory itself:
<?php
namespace Application\View\Helper;
use Zend\Mvc\Router\RouteMatch;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class RouteMatchHelperFactory implements FactoryInterface
{
/**
* #param ServiceLocatorInterface $serviceLocator
* #return RouteMatchHelper
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
$serviceManager = $serviceLocator->getServiceLocator();
/** #var RouteMatch $routeMatch */
$routeMatch = $serviceManager->get('Application')->getMvcEvent()->getRouteMatch();
return new RouteMatchHelper($routeMatch);
}
}
This code is not tested, but you get the point.
You can read more on writeing custom helperss in the official ZF2 documentation.
