我有一个购物车使用，我可以将产品添加到购物车。现在我想从我的购物车中删除和更新产品。 在下面的代码中，我展示了我的控制器、cart.php、路线和购物车页面。现在我可以将产品添加到购物车，但我在更新和删除购物车中的项目时遇到了一些问题。 可以帮我吗..谢谢
这是我得到的错误：
Call to undefined method App\Cart::remove()
不是：我正在为此购物车使用会话
这是我的 Cart.php
<?php
namespace App;
/**
*
*/
class Cart
{
public $items = NULL;
public $totalQty = 0;
public $totalPrice = 0;
public function __construct($oldCart)
{
if ($oldCart) {
$this->items = $oldCart->items;
$this->totalQty = $oldCart->totalQty;
$this->totalPrice = $oldCart->totalPrice;
}
}
public function add($item, $id){
$storedItem = ['qty' => 0, 'price' => $item->price, 'item' => $item];
if ($this->items) {
if (array_key_exists($id, $this->items)) {
$storedItem = $this->items[$id];
}
}
$storedItem['qty']++;
$storedItem['price'] = $item->price * $storedItem['qty'];
$this->items[$id] = $storedItem;
$this->totalQty++;
$this->totalPrice += $item->price;
}
}
这是我的 productController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Menu;
use App\Models\Category;
use App\Models\AboutUs;
use App\Models\Slider;
use App\Models\Product;
use App\Models\Info;
use App\Models\Banner;
use Session;
use App\Cart;
public function getAddToCart(Request $request, $id){
$product = Product::find($id);
$oldCart = Session::has('cart') ? Session::get('cart') : NULL;
$cart = new Cart($oldCart);
$cart->add($product, $product->id);
$request->session()->put('cart', $cart);
return redirect()->route('products')->with('success', 'Produit ajouté au panier avec succès.');
}
public function getCart($slug=NULL){
if (!Session::has('cart')) {
return view('shopCart');
}
$product = Product::where('slug', $slug)->first();
$menus = Menu::orderBy('id')->get();
$categoryall = Category::select('*')
->where('status', 1)
->get();
$infos = Info::where('status', 1)->first();
$oldCart = Session::get('cart');
$cart = new Cart($oldCart);
return view('shopCart', [
'products' => $cart->items,
'totalPrice' => $cart->totalPrice,
'product' => $product,
'menus' => $menus,
'categoryall' => $categoryall,
'infos' => $infos,
]);
}
public function destroy($id)
{
Cart::remove($id);
return back()->with('success', 'Produit Supprimé du Panier');
}
这是我的路线
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\HomeController;
use App\Http\Controllers\CartController;
Route::post('add-to-cart/{id}', [HomeController::class, 'getAddToCart'])
->name('addToCart');
Route::get('shoppingCart', [HomeController::class, 'getCart'])
->name('shoppingCart');
Route::get('/cart/productDelete', [HomeController::class, 'destroy'])
->name('cart.product.delete');
这是我的 shopCart.blade.php
