ZF2 - Get Data From Doctrine Orm In Dao Layer - php

Question

My Controller :
<?php
namespace Admin\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Admin\Controller;
use Admin\Service;
class AdminController extends AbstractActionController
{
public function indexAction()
{
$CrudService = $this->getServiceLocator()->get('CrudService');
return new ViewModel(
array('list'=> $CrudService->getList())
);
}
}
Service Layer :
<?php
namespace Admin\Service;
use Admin\Dao;
class CrudService
{
public function getList()
{
$CrudDao=new Dao\CrudDao();
$list=$CrudDao->getList();
return $list;
}
}
Dao Layer :
<?php
namespace Admin\Dao;
class CrudDao

}
every things is good work But My Problem is Dao Layer. that give me This
Error : not Found get Service Locator Class
I want get data From Doctrine in Dao Layer and Call Dao Method in Service Layer And Next Call Service With getServiceLocator in Controller

Answer 1

You have to inject all dependencies and use the service manager to get the classes.
In you Module.php you have to register and inject the dependencies:
class Module
{
// ...
public function getServiceConfig()
{
$factories = [
'Admin\Dao\CrudDao' = function (ServiceManager $serviceManager) {
$entityManager = $serviceManager->get('Doctrine\ORM\EntityManager'),
return new CrudDao($entityManager);
},
'Admin\Service\CrudService' = function (ServiceManager $serviceManager) {
return new CrudService($serviceManager);
}
];
return $factories;
}
}
The Dao will receive the EntityManager:
<?php
namespace Admin\Dao;
class CrudDao
{
private $entityManager;
public function __construct($entityManager)
{
$this->entityManager = $entityManager;
}
public function getList()
{
return
$this->entityManager
->getRepository('Admin\Entity\ProductEntity')
->findAll();
}
}
Your CrudService will receive the Service manager, then you can get the CrudDao:
<?php
namespace Admin\Service;
use Admin\Dao;
class CrudService
{
public function __construct($serviceManager)
{
$this->serviceManager = $serviceManager;
}
public function getList()
{
$CrudDao= $this->serviceManager->get('Admin\Dao\CrudDao');
$list = $CrudDao->getList();
return $list;
}
}
And your controller:
<?php
namespace Admin\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Admin\Controller;
use Admin\Service;
class AdminController extends AbstractActionController
{
public function indexAction()
{
$CrudService = $this->getServiceLocator()->get('Admin\Service\CrudService');
return new ViewModel(
array('list'=> $CrudService->getList())
);
}
}
