【问题描述】：
在我的电子商务网站中，我安装了 darryldecode/laravelshoppingcart 来添加购物车功能。
当我使用添加到购物车从产品页面将商品添加到购物车时，我收到此错误：- Darryldecode\Cart\Exceptions\InvalidItemException validation.required
这是我的第一个项目，请指导我如何解决这个问题。这个项目杀了我。在这个社区的帮助下，我可以完成这个项目。非常感谢。
CartController.php
class CartController extends Controller
{
public function index()
{
$cartItems = \Cart::session(auth()->id())->getContent();
return view ('cart',compact(cartItems));
}
public function show($id)
{
$product = Product::find($id);
return view('cart')->with(compact('product'));
}
public function destroy($itemId)
{
\Cart::session(auth()->id())->getContent();
return back;
}
public function add(Product $product)
{
// add the product to cart
\Cart::session(auth()->id())->add(array(
'id' => $product->id,
'name' => $product->prod_name,
'price' => $product->prod_price,
'quantity' => 1,
'attributes' => array(),
'associatedModel' => $product

【问题讨论】：
-
您是如何在上一个问题中解决这个完全相同的异常的？
-
在
CartController.php中检查public function add(Product $product) { dd($product->id); }
