ZF2 getServiceLocator in ControllerPlugin class

Question

I am trying to get a service / entity locator manager in a plugin class. How can i get this.

In my controller, I get it like this.

public function getEntityManager() { if(null === $this->em){ $this->em = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default'); } return $this->em; } public function setEntityManager(EntityManager $em) { $this->em = $em; } 

but in the plugin class I get an error in the line $ this-> getServiceLocator (). because it is not available in the plugin class.

How can I do the same to get some records and insert several into the database in the plugin.

I have an MvcEvent $ e object in my plugin class, can I use this to get entity manager?

I used this plugin to create my plugin

Any manual will be sent.

update:

 namespace Auth\Controller\Plugin; use Zend\Mvc\Controller\Plugin\AbstractPlugin; use Zend\EventManager\EventInterface as Event; use Zend\Authentication\AuthenticationService; use Doctrine\ORM\EntityManager; use Auth\Entity\User; use Zend\Mvc\MvcEvent; class AclPlugin extends AbstractPlugin { /* * @var Doctrine\ORM\EntityManager */ protected $em; public function checkAcl($e) { $auth = new AuthenticationService(); if ($auth->hasIdentity()) { $storage = $auth->getStorage()->read(); if (!empty($storage->role)) $role = strtolower ( $storage->role ); else $role = "guest"; } else { $role = "guest"; } $app = $e->getParam('application'); $acl = new \Auth\Acl\AclRules(); $matches = $e->getRouteMatch(); $controller = $matches->getParam('controller'); $action = $matches->getParam('action', 'index'); $resource = strtolower( $controller ); $permission = strtolower( $action ); if (!$acl->hasResource($resource)) { throw new \Exception('Resource ' . $resource . ' not defined'); } if ($acl->isAllowed($role, $resource, $permission)) { $query = $this->getEntityManager($e)->createQuery('SELECT u FROM Auth\Entity\User u'); $resultIdentities = $query->execute(); var_dump($resultIdentities); exit(); return; } else { $matches->setParam('controller', 'Auth\Controller\User'); // redirect $matches->setParam('action', 'accessdenied'); return; } } public function getEntityManager($e) { var_dump($this->getController()); // returns null exit(); if (null === $this->em) { $this->em = $this->getController()->getServiceLocator()->get('doctrine.entitymanager.orm_default'); } return $this->em; } public function setEntityManager(EntityManager $em) { $this->em = $em; } } 

I call the class above in module.php

  public function onBootstrap(Event $e) { $application = $e->getApplication(); $services = $application->getServiceManager(); $eventManager = $e->getApplication()->getEventManager(); $eventManager->attach('dispatch', array($this, 'loadConfiguration'),101); } public function loadConfiguration(MvcEvent $e) { $e->getApplication()->getServiceManager() ->get('ControllerPluginManager')->get('AclPlugin') ->checkAcl($e); //pass to the plugin... } 

I register this plugin in module.config.php file

 return array( 'controllers' => array( 'invokables' => array( 'Auth\Controller\User' => 'Auth\Controller\UserController', ), ), 'controller_plugins' => array( 'invokables' => array( 'AclPlugin' => 'Auth\Controller\Plugin\AclPlugin', ), ), );

What do you mean by the "Plugin Class"? If you are talking about abount controller plugins, you can access it using (from the controller plugin area): $this->getController()->getServiceLocator()->get('doctrine.entitymanager.orm_default'); .

For other classes, I usually create a factory that automatically introduces an instance of ServiceManager. For example, in the Module class:

 public function getServiceConfig() { return array( 'factories' => array( 'myServiceClass' => function(ServiceManager $sm) { $instance = new Class(); $instance->setServiceManager($sm); // Do some other configuration return $instance; }, ), ); } // access it using the ServiceManager where you need it $myService = $sm->get('myService');

changed the above AclPlugin class below

 namespace Auth\Controller\Plugin; use Zend\Mvc\Controller\Plugin\AbstractPlugin; use Zend\EventManager\EventInterface as Event; use Zend\Authentication\AuthenticationService; use Doctrine\ORM\EntityManager; use Auth\Entity\User; use Zend\Mvc\MvcEvent; use Zend\ServiceManager\ServiceManagerAwareInterface; use Zend\ServiceManager\ServiceManager; class AclPlugin extends AbstractPlugin implements ServiceManagerAwareInterface { /* * @var Doctrine\ORM\EntityManager */ protected $em; protected $sm; public function checkAcl($e) { $this->setServiceManager( $e->getApplication()->getServiceManager() ); $auth = new AuthenticationService(); if ($auth->hasIdentity()) { $storage = $auth->getStorage()->read(); if (!empty($storage->role)) $role = strtolower ( $storage->role ); else $role = "guest"; } else { $role = "guest"; } $app = $e->getParam('application'); $acl = new \Auth\Acl\AclRules(); $matches = $e->getRouteMatch(); $controller = $matches->getParam('controller'); $action = $matches->getParam('action', 'index'); $resource = strtolower( $controller ); $permission = strtolower( $action ); if (!$acl->hasResource($resource)) { throw new \Exception('Resource ' . $resource . ' not defined'); } if ($acl->isAllowed($role, $resource, $permission)) { $query = $this->getEntityManager($e)->createQuery('SELECT u FROM Auth\Entity\User u'); $resultIdentities = $query->execute(); var_dump($resultIdentities); foreach ($resultIdentities as $r) echo $r->username; exit(); return; } else { $matches->setParam('controller', 'Auth\Controller\User'); // redirect $matches->setParam('action', 'accessdenied'); return; } } public function getEntityManager() { if (null === $this->em) { $this->em = $this->sm->getServiceLocator()->get('doctrine.entitymanager.orm_default'); } return $this->em; } public function setEntityManager(EntityManager $em) { $this->em = $em; } /** * Retrieve service manager instance * * @return ServiceManager */ public function getServiceManager() { return $this->sm->getServiceLocator(); } /** * Set service manager instance * * @param ServiceManager $locator * @return void */ public function setServiceManager(ServiceManager $serviceManager) { $this->sm = $serviceManager; } }

Actually, getting a ServiceManager in a controller plugin is pretty simple!

Just use: $this->getController()->getServiceLocator()

Example:

 namespace Application\Controller\Plugin; use Zend\Mvc\Controller\Plugin\AbstractPlugin; class Translate extends AbstractPlugin { public function __invoke($message, $textDomain = 'default', $locale = null) { /** @var \Zend\I18n\Translator\Translator $translator */ $translator = $this->getController()->getServiceLocator()->get('translator'); return $translator->translate($message, $textDomain, $locale); } }
