Symfony3 Query Bulder? - symfony

Question

I am new to symfony 3 and I would like to understand how to get a value from a table according to the result found.
Let me explain :
According to the bass diagram below, each "produit" has a "poids"(nom) and a "valeur"(valeur)
view bdd:
I would like in my basket view to display the total value of the weight according to the quantity of course.
For example, I have a product at 2kg and another at 0.300kg, it would have to result in the value of 2.3kg which is in the weight table.
I can not perform this "function".
Here is my PanierController.
class PanierController extends Controller
{
public function supprimerAction(SessionInterface $session, $id)
{
$panier = $session->get('panier');
if (array_key_exists($id, $panier))
{
unset($panier[$id]);
$session->set('panier', $panier);
$this->addFlash('success', 'Article supprimé avec succès !');
}
return $this->redirect($this->generateUrl('panier'));
}
public function ajouterAction(SessionInterface $session, Request $request, $id)
{
if (!$session->has('panier')) {
$session->set('panier', array());
}
$panier = $session->get('panier');
if (array_key_exists($id, $panier)) {
if ($request->query->get('qte') != null) {
$panier[$id] = $request->query->get('qte');
}
$this->addFlash('success', 'Quantité modifié avec succès !');
} else {
if ($request->query->get('qte') != null) {
$panier[$id] = $request->query->get('qte');
} else {
$panier[$id] = 1;
}
$this->addFlash('success', 'Article ajouté avec succès !');
}
$session->set('panier', $panier);
return $this->redirect($this->generateUrl('panier'));
}
public function panierAction(SessionInterface $session)
{
if (!$session->has('panier')) {
$session->set('panier', array());
}
$em = $this->getDoctrine()->getManager();
$produits = $em->getRepository('EcommerceBundle:Produits')->findArray(array_keys($session->get('panier')));
return $this->render('EcommerceBundle:Default:panier/layout/panier.html.twig', array('produits' => $produits, 'panier' => $session->get('panier')));
}
public function livraisonAction()
{
// servira pour l'adresse de livraison
return $this->render('EcommerceBundle:Default:panier/layout/livraison.html.twig');
}
public function validationAction()
{
return $this->render('EcommerceBundle:Default:panier/layout/validation.html.twig');
}
}
If you need more information, please let me know.

#JasonRoman,
That is to say ?
For example to display the products in the Shopping Cart view, I use the ProductsRepository in the Shopping CartController:
public function panierAction(SessionInterface $session)
{
if (!$session->has('panier')) {
$session->set('panier', array());
}
$em = $this->getDoctrine()->getManager();
$produits = $em->getRepository('EcommerceBundle:Produits')->findArray(array_keys($session->get('panier')));
return $this->render('EcommerceBundle:Default:panier/layout/panier.html.twig', array('produits' => $produits, 'panier' => $session->get('panier')));
}
ProductsRepository:
class ProduitsRepository extends EntityRepository
{
public function findArray($array)
{
$qb = $this->createQueryBuilder('u')
->select('u')
->where('u.id IN (:array)')
->setParameter('array', $array);
return $qb->getQuery()->getResult();
}
}
The result is correct in the Cart view.
In the basket view, if I ask him to show me the total weight in the basket, I do:
{% Extends "::layout/layout.html.twig"%}
{% Set totalHT = 0%}
{% Set livraisonHT = 0%}
{% Block body%}
{% Set livraisonHT = livraisonHT + (panier[produit.id] * produit.poids.nom)%}
livraisonHT gives me the total weight
On the other hand, I do not know what function to write so that it shows me the corresponding value.
Currently I have in my basket:
One product at 2kg and another product at 0.3kg
{% Set livraisonHT = livraisonHT + (panier[produit.id] * product.poids.non)%}

Answer 2

I think I have put my finger on something,
In my basket view, if I do a dump (produits) i get, that:
array:1 [▼
0 => Produits {#546 ▼
-id: 5
-image: Media {#445 ▶}
-gamme: Gamme {#396 ▶}
-marque: Marque {#467 ▶}
-tva: Tva {#563 ▼
+__isInitialized__: true
-id: 11
-multiplicate: 0.83333333333334
-nom: "TVA 20 %"
-valeur: 20.0
…2
}
-poids: Poids {#670 ▼
+__isInitialized__: false
-id: 209
-nom: null
-valeur: null
…2
}
-categorie: Categories {#684 ▶}
-nom: "Phantom 4 Standard"
-resume: "le résumé"
-description: "La description longue"
-details: "details à voir"
-prix: 1000.0
-disponible: true
}
]
In "weight" the name and value are zero?
