我想使用laravel单击“添加到购物车”按钮时，将商品显示在购物车中吗？

Question

单击添加到购物车按钮时，我试图将产品添加到购物车中，但是遇到一些错误，如何解决该错误

请参见此错误非静态方法Gloudemans \\ Shoppingcart \\ Cart :: add（）不应静态调用http：// localhost / Projects / E-commerce / cart / action

控制者

      namespace App\ Http\ Controllers;
      use Illuminate\ Http\ Request;
      use Gloudemans\ Shoppingcart\ Cart;
      class CartController extends Controller {



       public
       function cart() {
        $cartcontent = Cart::Content();
        return view('front_end/cart', ['cartcontent' => $cartcontent]);
       }

       public
       function addcart(Request $request) {
        $image = [$request - > product_image];

        $add = Cart::add(
         $request - > productid,
         $request - > product_name,
         $request - > qty,
         $request - > product_price,
         $image

        );
        if ($add) {
         redirect('/cart');

        }
       }

HTML视图

<tbody class="cart-table__body">
                  @foreach($cartcontent as  $cartcontents)
    <tr class="cart-table__row">
        <td class="cart-table__column cart-table__column--image">
            <a href="{{$cartcontents->product_image}}">

                </td>
            </tr>
                   @endforeach


        </tbody>

使用此方法将购物车数据传递到视图

 public function cart()
       {
        $cartcontent = Cart::Content();
        $cart_data = [];
        foreach($cart_list as $cart){
               $cart_data [] = [

              //define keys as per your cart's content and pass $cart_data in your view
               //like this: 
              // 'product' => $cart->product

               ];
          }

        return view('front_end/cart')->with(compact(['cart_data']));

    }

之后，就像您一样在您的视图中循环遍历cart_data。
