我想使用laravel單擊“添加到購物車”按鈕時，將商品顯示在購物車中嗎？

Question

單擊添加到購物車按鈕時，我試圖將產品添加到購物車中，但是遇到一些錯誤，如何解決該錯誤

請參見此錯誤非靜態方法Gloudemans \\ Shoppingcart \\ Cart :: add（）不應靜態調用http：// localhost / Projects / E-commerce / cart / action

      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');

        }
       }

使用此方法將購物車數據傳遞到視圖

 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，就像您一樣在您的視圖中循環遍歷cart_data。
