使用此方法将购物车数据传递到您的视图

 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']));

    }

在您的视图中遍历 cart_data 之后，就像您所做的那样。
