This is my ProdcutController.php

        public function getCheckout()
            { $oldCart= Session::get('cart');
                $cart= new Cart($oldCart);
                $total= $cart->totalPrice;
                return view('shop.checkout',['total=> $total']);
            }
        }

This is my routes

    Route::get('/checkout',[
        'uses' =>'ProductController@getCheckout',
        'as' => 'checkout'

        ]);

    Route::post('/checkout',[
    'uses'=> 'ProductController@postCheckout',
    'as'=>'checkout'
        ]);
