zend framework 2 getServiceLocator Empty - php

Question

I've been trying to figure it out by myself reading online and applying tons of answers form here, but to no avail unfortunately.
I have two Modules on my zf2 application, one called Services and one called Agent.
Now, in my Services module everything seems to work fine, I can get my serviceLocator, hence my configuration, and work with it. In my Agent Module's controller however, I don't seem to be able to do the same.
This is part of my AgentController:
use Zend\Mvc\Controller\AbstractActionController;
class AgentController extends AbstractActionController
{
protected $serviceLocator;
public function ValidateAction()
{
$this->serviceLocator = $this->getServiceLocator()->get('config');
//... Using the config
}
}
In my module.cofig.php I have the following:
'controllers' => array(
'invokables' => array(
'Agent\Controller\Agent' => 'Agent\Controller\AgentController',
),
),
I have tried many solutions: changing and adding methods to the Module.php, changing the module.config etc.. Where am I wrong?
Thanks,
Andrea

Answer 1

The class variable $this->serviceLocator is used by the controller class to hold the service locator instance. In your example you assigning the config array to this variable (thus replacing the service locator instance with an array). Subsequent calls to $this->getServiceLocator() will then return the config array instead of the service locator object, which is the likely cause of the error you're getting.
I'd suggest either using a local variable instead:
public function ValidateAction()
{
$config = $this->getServiceLocator()->get('config');
//... Using the config
}
or assigning to a class variable with a different name:
public function ValidateAction()
{
$this->config = $this->getServiceLocator()->get('config');
//... Using the config
}
