购物车不显示项目laravel

Question

我有一个订单按钮应该是重定向用户到购物车页面与订购的项目

<p class="btn-holder"><a href="{{route('addCart',$food->id) }}" class="btn btn-primary btn-block text-center" role="button" > Order this</a> </p>

这是web.php路线

Route::get('add-to-cart/{id}', 'FoodsController@addToCart')->name('addCart');

这是addToCart函数

public function addToCart($id){
        $food = Food::find($id);   

        if(!$food) {

            abort(404);

        }

        $cart = session()->get('cart');

        // if cart is empty then this the first product
        if(!$cart) {

            $cart = [
                    $id => [
                        // "productId" => $food->id,
                        "name" => $food->food_item,
                        "quantity" => 1,
                        "price" => $food->price,

                    ]
            ];


            session()->put('cart', $cart);


            return redirect()->back()->with('success', 'Product added to cart successfully!');
        }

        // if cart not empty then check if this product exist then increment quantity
        if(isset($cart[$id])) {

            $cart[$id]['quantity']++;

            session()->put('cart', $cart);

            return redirect()->back()->with('success', 'Product added to cart successfully!');

        }

        // if item not exist in cart then add to cart with quantity = 1
        $cart[$id] = [
            // "productId" => $food->id,
            "name" => $food->food_item,
            "quantity" => 1,
            "price" => $food->price,

        ];


        session()->put('cart', $cart);

        return redirect()->back()->with('success', 'Product added to cart successfully!');
    }

但是当我点击按钮时，它不会重定向到购物车页面，它会一直加载到同一个位置。

我尝试使用dd（$Food）；在addToCart函数上转储变量，它输出正确的结果

我想这正是“重定向”（redirect）的意思-

您应该使用：

redirect('cartRouteName')->with('success', 'Product added to cart successfully!');

将cartRouteName替换为要将用户重定向到的实际命名路由。
