ZF2 Get params in factory - php

Question

I have a dynamic category navigation. In the navigation factory I want to get a param from the route. How can I do this?
In my view
<?php echo $this->navigation('CategoryNavigation')->menu()->setUlClass('list-group'); ?>
In my module.php:
public function getServiceConfig()
{
return array(
'factories' => array(
'CategoryNavigation' => 'Application\Navigation\CategoryNavigation',
)
);
}
This is my navigation factory. I need to get the slug from the route where {{ store slug }} (2x) is defined.
<?php
namespace Application\Navigation;
use Zend\ServiceManager\ServiceLocator;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\Navigation\Service\DefaultNavigationFactory;
class CategoryNavigation extends DefaultNavigationFactory
{
protected $sl;
protected function getPages(ServiceLocatorInterface $serviceLocator)
{
if (null === $this->pages) {
$em = $serviceLocator->get('Doctrine\ORM\EntityManager');
$storerepository = $em->getRepository('ApplicationShared\Entity\Store');
$store = $storerepository->findOneBy(array('slug' => '{{ store slug }}'));
$fetchMenu = $store->getCategories();
$configuration['navigation'][$this->getName()] = $this->buildNavigation($fetchMenu);
if (!isset($configuration['navigation'])) {
throw new Exception\InvalidArgumentException('Could not find navigation configuration key');
}
if (!isset($configuration['navigation'][$this->getName()])) {
throw new Exception\InvalidArgumentException(sprintf(
'Failed to find a navigation container by the name "%s"',
$this->getName()
));
}
$application = $serviceLocator->get('Application');
$routeMatch = $application->getMvcEvent()->getRouteMatch();
$router = $application->getMvcEvent()->getRouter();
$pages = $this->getPagesFromConfig($configuration['navigation'][$this->getName()]);
//
$this->pages = $this->injectComponents($pages, $routeMatch, $router);
}
return $this->pages;
}
protected function buildNavigation($elements, $parentid = null){
foreach ($elements as $index => $element) {
if (!$element->getParent()) {
$branch[$element->getCategoryName()] = $this->navigationItem($element);
}
}
return $branch;
}
protected function navigationItem($element){
$branch['label'] = $element->getCategoryName();
$branch['route'] = 'store/type/catalog';
$branch['params'] = array('slug' => '{{ store slug }}','category' => $element->getSlug());
if(count($element->getChildren()) > 0){
foreach($element->getChildren() as $element){
$branch['pages'][] = $this->navigationItem($element);
}
}
return $branch;
}
}
Or are there better way's to achieve this?

Answer 1

Searching for a few hours, in the end asking it on stack, and now I find the answer in a half hour.
I just had to ad this in my factory
$router = $serviceLocator->get('router');
$request = $serviceLocator->get('request');
// Get the router match
$routerMatch = $router->match($request);
$this->slug = $routerMatch->getParam("slug");

Answer 2

Or the following for ZF3:
$container->get('Application')->getMvcEvent()->getRouteMatch()->getParam('whateverYouWant', false);
