Access session variable from different controller in symfony - symfony

Question

i want to create an array as a session table to put it empty in the beggining for my cart shop to display nothing as an empty cart and when i press AddtoCart i want get that array and do an array_push with the new items but i didn't know how to do it
This is the first controller when i create the array empty
public function FrontAction()
{
$pro=new Produit();
$pro->setNom('');
$pro->setQuantite(0);
$pro->setPrix(0);
$em = $this->getDoctrine()->getManager();
$sess=new Session();
$sess->setName('PANIER');
$sess=array('');
array_push($sess,$pro->getNom(),$pro->getQuantite(),$pro->getPrix());
$paniers = $em->getRepository(Panier::class)->findByUserId(1);
$produits = $this->getDoctrine()->getRepository(Produit::class)->findAll();
$boutiques = $this->getDoctrine()->getRepository(Boutique::class)->GetBestShopsDQL();
if ($paniers != null)
{
$prixTotal = 0;
foreach ($paniers as $panier) {
$prixTotal += $panier->getPrixTotal();
}
$resultCount = count($paniers);
return $this->render('BoutiqueBundle:FrontViews:ListBoutique.html.twig', array('produits' => $produits, 'boutiques' => $boutiques,'paniers' => $paniers, 'prixTotal' => $prixTotal,'resultCount' => $resultCount));
}
return $this->render('BoutiqueBundle:FrontViews:ListBoutique.html.twig', array('produits' => $produits, 'boutiques' => $boutiques,'sess'=>$sess));
}
and this is the second controller where i want to fill that empty array with new items
public function ajouterauPanierAction($id)
{
$ses=new Session();
$ses->getName('PANIER');
$test=array('');
$test=$ses;
// $user_id = $this->getUser()->getId(); //à modifier!!!!!
$em = $this->getDoctrine()->getManager();
$produit = $em->getRepository(Produit::class)->find($id);
$test = $em->getRepository(Panier::class)->findExistant($id, 1);
// $session->replace(array_push($produit,));
if(($produit != null)&&(empty($test)))
{
array_push($test,$produit->getNom(),$produit->getQuantite(),$produit->getPrix());
/* $panier = new Panier();
$panier->setProduitId($produit->getId());
$panier->setUserId(1); //à changer avec le fos
$panier->setDate(new \DateTime("now"));
$panier->setPrixTotal($produit->getPrix());
$em->persist($panier);
*/ $em->flush();
$msg = "success";
// return $this->redirectToRoute('Dashboard');
}
else
{
//return $this->render('BoutiqueBundle:FrontViews:404.html.twig');
$msg = "failure";
}
return new JsonResponse(array('msg' => $msg));
}
i didn't know how to do it correctly or if my idea is wrong so hope u guys got what i need to do

Here is how I am doing it in Symfony 4, (I think this part is unchanged). First I have declared my session keys as class constants on the entities to avoid collisions.
class Appointment
{
const SESSION_KEY = 'confirmed_app_entity_appointment';
...
}
Then in the controller use the SessionInterface and it will get autowired into your controller method with a typehinted parameter (SessionInterface $session). Symfony will handle starting the session, just set, get, and/or remove the key as needed.
use Symfony\Component\HttpFoundation\Session\SessionInterface;
...
public function confirmAppointment($first_name, $last_name, $time, SessionInterface $session)
{
...
$session->set(Appointment::SESSION_KEY, $appointment);
$session->set(StaffMember::SESSION_KEY_SELECTED_STAFF, $member);
...
if ($this->isConflict($appointment)) {
$session->remove(Appointment::SESSION_KEY);
$session->remove(StaffMember::SESSION_KEY_AUTH);
$this->addFlash('error', 'Failed to create Appointment, conflict found');
return $this->redirectToRoute('customer');
}
...
}
public function saveAppointment(SessionInterface $session)
{
if (!empty($session->get(Appointment::SESSION_KEY))) {
$appointment = $session->get(Appointment::SESSION_KEY);
}
...
}
