Session container not working in zf2? - php

Question

I have seen many questions on StackOverflow and I have this code
use Zend\Session\Container;
class IndexController extends AbstractActionController {
public function indexAction() {
$userSession = new Container('user');
$userSession->username = 'Sandhya';
return new ViewModel();
}
}
When I am printing the $userSession container in the controller it is giving me this output
Zend\Session\Container Object (
[name:protected] => user
[manager:protected] => Zend\Session\SessionManager Object (
[defaultDestroyOptions:protected] => Array (
[send_expire_cookie] => 1
[clear_storage] =>
)
[name:protected] =>
[validatorChain:protected] =>
[config:protected] => Zend\Session\Config\SessionConfig Object (
[phpErrorCode:protected] =>
[phpErrorMessage:protected] =>
[rememberMeSeconds:protected] => 240
[serializeHandler:protected] =>

[0] => nocache
[1] => public
[2] => private
[3] => private_no_expire
)
[validHashBitsPerCharacters:protected] => Array (
[0] => 4
[1] => 5
[2] => 6
)

[useCookies:protected] => 1
[options:protected] => Array (

)
)
[defaultConfigClass:protected] => Zend\Session\Config\SessionConfig
[storage:protected] => Zend\Session\Storage\SessionArrayStorage Object (

[saveHandler:protected] =>

[storage:protected] => Array ( )
[flag:protected] => 2
[iteratorClass:protected] => ArrayIterator
[protectedProperties:protected] => Array (
[0] => name
[1] => manager
[2] => storage
[3] => flag
[4] => iteratorClass
[5] => protectedProperties
)
)
It means there is nothing like username...
But when I am printing the S_SESSION it gives me this output...
Array (
[__ZF] => Array (
[_REQUEST_ACCESS_TIME] => 1429081041.81
)
[user] => Zend\Stdlib\ArrayObject Object (
[storage:protected] => Array (
[username] => Sandhya
)
[flag:protected] => 2
[iteratorClass:protected] => ArrayIterator
[protectedProperties:protected] => Array (
[0] => storage
[1] => flag
[2] => iteratorClass
[3] => protectedProperties
)
)
)
There is a field username...
But when I am trying to get the $_SESSION in view it gives me the same output as above..
The problem is I am not able to get the username in both the container as well as in $_SESSION.
I need it in the controllers.
what can be the problem need help? Thank you.

Answer 1

I think you have to work on your configuration.
You have to setup a common SessionManager to manage handling of your session information.
Something like this:
$sessionConfig = new SessionConfig();
$sessionConfig->setOptions($config);
$sessionManager = new SessionManager($sessionConfig);
$sessionManager->start();
Container::setDefaultManager($sessionManager);
I would suggest registering your SessionManager config in your ServiceManager instance and then use it throughout the application.
'service_manager' => array(
'factories' => array(
'session_manager' => 'My\Factory\SessionManagerFactory'
)
)
You can then get your SessionManager in any controller:
$sessionManager = $this->serviceLocator->get('session_manager');
And if you create a new Container it will use your common/default SessionManager instance automatically so all will be managed in one place.
$userSession = new Container('user');
$userSession->getManager() === $this->serviceLocator->get('session_manager') // true
On how to register your session_manager I will refer to the official ZF2 documentation.

Answer 2

You can use the following code:
$userSession = new Container('user');
//To check the session variable in zf2:
if($userSession->offsetExists('username')){
//Your logic after check condition
}
This will return true or false on the basis of session exist or not.
//To get the value of session:
echo $user->offsetGet('username');
Above code will return the value of session index username.
Instead of $userSession->username = 'Sandhya'; you can use below code:
$user->offsetSet('username','Sandhya');
This is zf2 standard, which is used by session container in zf2.

Answer 3

you can just get your username from session in controllers.
$userSession = new Container('user');
$username = $userSession->username ;
var_dump($username); //Sandhya
it work for me . try it !
