通过Symfony中的Ajax为ArrayCollection数据传递POST json对象

问题描述

我想在我的Symfony 5应用程序中插入订单数据。 Order实体类的OrderDetails ArrayCollection数据。 Order和OrderDetails ArrayCollection数据通过JSON对象Ajax发布获取。如何通过Symfony中的Ajax为ArrayCollection数据传递POST json对象。

实体代码：

    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;
    
            return $this;
        }
    
        public function getName(): ?string
        {
            return $this->name;
        }
    
        public function setName(string $name): self
        {
            $this->name = $name;
    
            return $this;
        }
    
     
        /**
         * @return Collection|OrderDetail[]
         */
        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文件代码：

 // 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');    
        }   

    });

控制器代码：

  /**
     * @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);

    }

如何在控制器中获取ArrayCollection数据并插入其数据库表。

解决方法

我建议您使用带有表集的symfony表单，它会自行工作。您似乎想使用ajax，即使使用表单，也可以使用javascript提交表单，而无需重新加载页面。

这将有助于：https://symfony.com/doc/current/form/form_collections.html

如果您真的不想这样做，那么完全可以提交包含订单明细数据的数组，然后对其进行迭代，为每个数据创建一个OrderDetail实体，将其持久化，等等。
