如何解决商品的总价格不会根据其在Laravel开发的购物车中的数量而变化有什么问题吗？
我正在开发一个电子商务网站。当项目数量更改时，项目的总价也需要更改。但就我而言，它不会按数量变化。 将项目添加到购物车后，“购物车”列表可以正常工作。当我更新一个项目的数量时，该项目的总价不会改变。 https://github.com/darryldecode/laravelshoppingcart 我安装了此购物车包。
CartController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Product;
use App\Category;
use Darryldecode\Cart\Cart;
class CartController extends Controller
{
public function index()
{
// $cartItems = \Cart::session(auth()->id())->getContent();
return view ('cart');
}
public function show($id)
{
$product = Product::find($id);
return view('cart')->with(compact('product'));
}
public function update($rowId)
{
\Cart::session(auth()->id())->update($rowId,[
'quantity' => [
'relative' => true,'value'=> request('quantity')
]
]);
return back();
}
public function destroy($itemId)
{
\Cart::session(auth()->id())->remove($itemId);
return back();
}
public function addtocart(Product $product)
{
\Cart::session(auth()->id())->add(array(
'id' => $product->id,'name' => $product->prod_name,'price' => $product->prod_price,'quantity' => 1,'attributes' => array(),'associatedModel' => $product
));
return redirect()->back();
}
}
