ZF2 - Injecting pages to navigation before controller is called

Question

I\'m creating a dynamic Application in which the content is added through a CMS. Inside the CMS, I\'m setting a db entry which states what module to use for each content pag

The navigation containers are composed by factory classes. The easiest approach is to write your own factory and have the getPages() method fetch pages from a database instead of from config. If you extend from the AbstractNavigationFactory you only need to write a couple of methods.

pages) {

            $application = $serviceLocator->get('Application');
            $routeMatch  = $application->getMvcEvent()->getRouteMatch();
            $router      = $application->getMvcEvent()->getRouter();

            // get your pages from wherever...
            $pages       = $this->getPagesFromDB();

            $this->pages = $this->injectComponents($pages, $routeMatch, $router);
        }
        return $this->pages;
    }

    public function getName()
    { 
         // this isn't used if fetching from db, it's just here to keep the abstract factory happy
         return 'cms';
    }
}

Add the factory to the service manager, just like you would for other containers

'service_manager' => array(
    'factories' => array(
        'CmsNavigation' => 'Application\Navigation\Service\CmsNavigationFactory',
    ),
),

And use it with the navigation view helpers in the same way

navigation()->menu('CmsNavigation'); ?>
