I have two entities - one is Product, second - Order. I've created controllers to navigate between page of ProductController that lists the whole ProductRepository to the page of OrderController, which should:

• take a Product ID to show its properties on the Order page (name and price)
• have a form with quantity and "customer's" email to be added to the Order
• calculate the price x quantity and add to the Order

I can't figure how to access the passed project's properties. I am able to access it via addProduct method of the Order entity, but cannot reach them to show them in twig nor manipulate them on variables as described above.

I'm sure it's a simple stuff but I am not sure even how to ask google the right way on this.

we click on a product from ProductRepository with

 <a href="{{ path('app_order', {id: product.id}) }}">

and we go to OrderController

OrderController:

<?php

namespace App\Controller;


class OrderController extends AbstractController
{
    #[Route('/order', name: 'app_order')]
    public function addToOrder(ManagerRegistry $doctrine, Request $request, EntityManagerInterface $em): Response
    {
        $orderedProductId = (int) ($request->query->get('id'));
        $pPrice = 1;
        $order = new Order();
        $order->addProduct($doctrine->getRepository(Product::class)->find($orderedProductId));
        $form = $this->createFormBuilder($order)
            ->add('clientEmail', TextType::class)
            ->add('quantity', IntegerType::class)
            ->add('makeOrder', SubmitType::class, ['label' => 'Make Order'])
            ->getForm();
        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            //$data = $form->getData();
            $order->setStatus("Pending");
            $order->setTotalSum(1);
            $em->persist($order);
            $em->flush();
        }
        return $this->render('order/index.html.twig', [
            'form'=> $form->createView(),
            'order'=> $order
        ]);
    }
}

The entities look like this:

Product

<?php

namespace App\Entity;

use App\Repository\ProductRepository;
use Doctrine\ORM\Mapping as ORM;

#[ORM\Entity(repositoryClass: ProductRepository::class)]

    private $price;

    #[ORM\Column(type: 'boolean')]
    private $visible;

    #[ORM\ManyToOne(targetEntity: Order::class, inversedBy: 'product')]
    private $orderIds;

    public function getId(): ?int

Order:

    /**

    public function getProduct(): Collection

OK I got this. Changed a property taken by OrderController from EntityManager to ProductRepository, then

$product= $productRepository->find($orderedProductId);

also: this is helpful: Getting only ID from entity relations without fetching whole object in Doctrine

solved!
