zf2 How to get user details with AuthenticationService - php

Question

I've created a module to authenticate a user. Now, after login I go to the index action and the system tells me that the authentication is all working fine. But What I want is to print some more user details from the Users table. When I try:
print_r($this->getServiceLocator()->get('AuthService')->getAdapter()->getResultRowObject());
I get no result. What am I doing wrong?
Thanks for your help.
In my module.php I've the following code(snippet):
public function getServiceConfig()
{
return array(
'abstract_factories' => array(),
'aliases' => array(),
'factories' => array(
// Some more code here but removed for simplicity
// Autentication
'AuthService' => function ($sm) {
$adapter = $sm->get('master_db');
$dbAuthAdapter = new DbAuthAdapter ( $adapter, 'Users', 'email', 'password' );
$auth = new AuthenticationService();
$auth->setAdapter ( $dbAuthAdapter );
return $auth;
},
// Some more code here but removed for simplicity
}
In my IndexController.php I've the following (snippets):
public function indexAction()
{
if(!$this->getServiceLocator()->get('AuthService')->hasIdentity()){
return $this->redirect()->toUrl('login');
}
echo "hello, it works!";
exit;
}
public function loginAction(){
$form = $this->getServiceLocator()->get('LoginForm');
$viewModel = new ViewModel(array('form' =>
$form));
return $viewModel;
}
public function processAction(){
// Lots of code here
if($bcrypt->verify($loginData['password'], $userData->password))
{
$this->getAuthService()
->getAdapter()
->setIdentity($loginData['email'])
->setCredential($userData->password);
$result = $this->getAuthService()->authenticate();
}
// Lots of code here where I check if $result->isValid and route to the
// correct action
}
public function getAuthService() {
if(!isset($this->authservice)) {
$this->authservice = $this->getServiceLocator()->get('AuthService');
}
return $this->authservice;
}

Instead of refering to the authentication result object (which properly only exists in the authentication request) you can simply store user details in the authentication identity (#see http://framework.zend.com/manual/2.1/en/modules/zend.authentication.intro.html).
For your case you could also store user specific details right after the validation of the authentication result in the authentication storage:
if ($result->isValid()) {
//authentication success
$resultRow = $this->authService->getAdapter()->getResultRowObject();
$this->authService->getStorage()->write(array(
'id' => $resultRow->id,
'user_agent' => $request->getServer('HTTP_USER_AGENT'))
);
}
