redirect for only admin module - php

Question

I have the following code inside my Admin Module.php
public function onBootstrap(MvcEvent $e)
{
$application = $e->getApplication();
$em = $application->getEventManager();
if(!SystemUtils::isApiRequest()){
$em->attach(\Zend\Mvc\MvcEvent::EVENT_DISPATCH, array($this,'initUser'),10000);
}
}
public function initUser(MvcEvent $e)
{
$isLoggedIn=false;
// determined elsewhere
$action = Pluto::registry('application_action');
if($action!=='login' && !$isLoggedIn){
$viewHelperManager = $e->getApplication()->getServiceManager()->get('ViewHelperManager');
$renderer = $viewHelperManager->getRenderer();
$url = $renderer->plutourl('login');
$response = $e->getApplication()->getServiceManager()->get('Response');
$response->getHeaders()->clearHeaders()->addHeaderLine('Location', $url);
$response->setStatusCode(302)->sendHeaders();
exit();
}
}
The problem is this is only supposed to activate when inside a page within the admin module and you are not logged in but its operating for every request regardless of the module the code is inside
I want to limit this check to just when accessing the admin module.
Update
$sm = $e->getApplication()->getServiceManager();
$router = $sm->get('router');
$request = $sm->get('request');
$matchedRoute = $router->match($request);
returns the admin controller class name which i can use but i want it for all of the admin controller classes

Answer 1

You can use the shared event manager to attach to events in a given name space. In the example below we attach to an event only for the current modules namespace.
use Zend\Mvc\MvcEvent;
public function onBootstrap(MvcEvent $e)
{
$app = $e->getApplication();
$em = $app->getEventManager()->getSharedManager();
$sm = $app->getServiceManager();
$em->attach(__NAMESPACE__, MvcEvent::EVENT_DISPATCH, function ($e) use ($sm) {
/**
* this will be triggered only by controlers in
* this module/namespace...
*/
$this->doSomething();
});
}
You could add this inside your admin module and only this event will only be listened to for classes inside this module / namespace.

You should use the MvcEvent object!
If all controllers are under a single namespace, for instance \Admin\Controller:
$namespace = 'Admin\\Controller\\';
$matchController = $e->getRouteMatch()->getParam('controller');
if( $namespace === substr($matchController, 0, strlen($namespace))
{
// check here if user is logged in.
}
else {
// not an admin controller, do nothing.
}
