Laravel 未定义路线[products.all]。（\resources\views\product\cart.blade.php）

它工作正常，但当我添加删除购物车产品功能时，它开始显示未定义的错误路径[products.all]。（resources\views\product\cart.blade.php）

控制器：

  public function deleteCartProduct(Product $product)
{
    $oldCart = Session::has('cart') ? Session::get('cart') : null;
    $cart = new Cart($oldCart);
    $cart->delProduct($product);
    Session::put('cart', $cart);

    return redirect()->route('product.cart')->with('flash_message_success', 'Product product has been removed from Cart');
}

模型

刀片

@除非（空（$contents））
@csrf
product_image}“alt=”IMG-product“>
{{$cartItem['product']->product_name}
${$cartItem['product']->product_price}
${{$cartItem['price']}
@endforeach
@否则
购物车中没有任何产品
@结束语

请也添加有问题的路由文件。&error明确指出“products.all”路由未定义。您正在使用该视图。

  public function deleteProduct($product)
{
    if ($this->contents) {
        if (array_key_exists($product->product_slug, $this->contents)) {
            $delProduct = $this->contents[$product->slug];
            $this->totalQty -= $delProduct['qty'];
            $this->totalPrice -= $delProduct['price'];
            array_forget($this->contents, $product->slug);
        }
    }
}

  Route::get('/cart/delete-product/{id}','ProductController@deleteCartProduct')->name('deleteCartProduct');

  @unless(empty($contents))

  <form action="{{ route('cart.delete', $product) }}" method="get">
