ServiceManager in ZF3 - php

Question

I know that this has been covered extensively in other threads, but I'm struggling to work out how to replicate the effect of $this->getServiceLocator() from ZF2 controllers in ZF3 ones.
I have tried creating a factory using the various other answers and tutorials that I've found here and elsewhere, but ended up in a mess with each of them, so I'm pasting my code as it was when I started in the hope that someone can point me in the right direction?
From /module/Application/config/module.config.php
'controllers' => [
'factories' => [
Controller\IndexController::class => InvokableFactory::class,
],
],
From /module/Application/src/Controller/IndexController.php
public function __construct() {
$this->objectManager = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');
$this->trust = new Trust;
}

Answer 1

You can not use $this->getServiceLocator() in controller any more.
You should add one more class IndexControllerFactory where you will get dependencies and inject it in IndexController
First refactor your config:
'controllers' => [
'factories' => [
Controller\IndexController::class => Controller\IndexControllerFactory::class,
],
],
Than create IndexControllerFactory.php
<?php
namespace ModuleName\Controller;
use ModuleName\Controller\IndexController;
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
class IndexControllerFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container,$requestedName, array $options = null)
{
return new IndexController(
$container->get(\Doctrine\ORM\EntityManager::class)
);
}
}
At the end refactor you IndexController to get dependencies
public function __construct(\Doctrine\ORM\EntityManager $object) {
$this->objectManager = $object;
$this->trust = new Trust;
}
You should check official documentation zend-servicemanager and play around a little bit...

Answer 2

Whilst the accepted answer is correct, I will implement mine a bit differently by injecting the container into the controller and then get other dependencies in constructor like so...
<?php
namespace moduleName\Controller\Factory;
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
use moduleName\Controller\ControllerName;
class ControllerNameFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
return new ControllerName($container);
}
}
Your controller should look something like this:
namespace ModuleName\Controller;
use Doctrine\ORM\EntityManager;
use Zend\ServiceManager\ServiceManager;
class ControllerName extends \App\Controller\AbstractBaseController
{
private $orm;
public function __construct(ServiceManager $container)
{
parent::__construct($container);
$this->orm = $container->get(EntityManager::class);
}
In your module.config, be sure to register the factory like so:
'controllers' => [
'factories' => [
ControllerName::class => Controller\Factory\ControllerNameFactory::class,
],
