Question

I want to insert Order data in my Symfony 5 application. OrderDetails ArrayCollection data of an Order entity class. Order and OrderDetails ArrayCollection data get by JSON object ajax post. How to passing POST json object for ArrayCollection data by ajax in Symfony.
Entity Code:
class Order
{
public const NUM_ITEMS = 10;
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=255)
*/
private $orderNo;
/**
* #ORM\Column(type="datetime")
*/
private $orderDate;
/**
* #ORM\Column(type="string", length=255)
*/
private $name;
/**
* #ORM\OneToMany(targetEntity=OrderDetail::class, mappedBy="orders")
*/
private $orderDetails;
public function __construct()
{
$this->orderDetails = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getOrderNo(): ?string
{
return $this->orderNo;
}
public function setOrderNo(string $orderNo): self
{
$this->orderNo = $orderNo;
return $this;
}
public function getOrderDate(): ?\DateTimeInterface
{
return $this->orderDate;
}
public function setOrderDate(\DateTimeInterface $orderDate): self
{
$this->orderDate = $orderDate;

*/
public function getOrderDetails(): Collection
{
return $this->orderDetails;
}
public function addOrderDetail(OrderDetail $orderDetail): self
{
if (!$this->orderDetails->contains($orderDetail)) {
$this->orderDetails[] = $orderDetail;
$orderDetail->setOrders($this);
}
return $this;
}
public function removeOrderDetail(OrderDetail $orderDetail): self
{
if ($this->orderDetails->contains($orderDetail)) {
$this->orderDetails->removeElement($orderDetail);
// set the owning side to null (unless already changed)
if ($orderDetail->getOrders() === $this) {
$orderDetail->setOrders(null);
}

return $this;
}
}
JS File Code:
// Creating Order Json Object
var orderObj = { "orderNo":"", "orderDate":"", "name":"" };
orderObj.orderNo = $("#text_name").val();
orderObj.orderDate = $("#text_mobileno").val();
orderObj.name = $("#text_email").val();
// Set 2: Ajax Post
// Here i have used ajax post for saving/updating information
$.ajax({
type: 'POST',
contentType: 'application/json;',
url:'/cart/ordersave',
data: JSON.stringify(orderObj),
dataType: 'json',
success: function (response)
{
// alert(response['data']);
//alert(1);
},
error:function(){
alert('ajax failed');
}
});
Controller Code:
/**
* #Route("/cart/ordersave", name="cart_order_save", methods={"POST"})
*
*/
public function ordersave(Request $request, SessionInterface $session)
{
if ($request->isXMLHttpRequest()) {
$content = $request->getContent();
if (!empty($content)) {
$params = json_decode($content, true);
$order = new Order();
$order->setOrderNo('ON-101/20');
$order->setOrderDate(new \DateTime());
$order->setName($params['name']);
$order->setMobileNo($params['mobileno']);
$order->setEmail($params['email']);
$order->setDeliveryAddress($params['address']);
$order->setCity($params['city']);
$order->setState($params['state']);
$order->setZipcode($params['zipcode']);
$order->setPaymentBy(1);
$order->setDeliveryDate(new \DateTime());
$em = $this->getDoctrine()->getManager();
$em->persist($order);
$em->flush();
$lastId = $order->getId();
$session->set('lastOrderIDSession', $lastId);
}
$this->addFlash('notice', 'Order created successfully!');
return new JsonResponse(array('data' => $lastId));
// return new JsonResponse(array('data' => $params));
}
return new Response('Error!', 400);
}

I'd advise you using a symfony form, with a form collection, and it will work by itself. You seem to want to use ajax, and even with forms, you can submit the form in javascript without reloading the page.
This will help : https://symfony.com/doc/current/form/form_collections.html
If you really don't want to do that, well you totally can submit an array with the order details data, then iterate on it, create an OrderDetail entity for each, persist them, etc...
