Question

当我点击添加到购物车按钮时会发生什么如何使用 laravel 修复此错误？

请查看此错误 传递给 Gloudemans\Shoppingcart\Cart::add() 的参数 5 必须是数组类型，给定字符串，在 C:\xampp\htdocs\Projects\E-commerce\vendor\laravel\framework\src\Illuminate\Support 中调用\Facades\Facade.php 在第 245 行

，实际上Cart::add 方法在第四个参数上采用价格，第五个参数用于您可以传递选项数组的选项

例如：

Cart::add(['id' => '293ad', 'name' => 'Product 1', 'qty' => 1, 'price' => 9.99, 'options' => ['size' => 'large']]);

你可以做的是像这样修改你的函数，它应该可以工作，希望：

public function addcart(Request $request){
    $image = [$request->product_image];
    Cart::add($request->productid,$request->product_name,$request->qty,$request->product_price,$image);
    return redirect()->route('cart.index')->with('successmessage','Items added successfully');
}

希望对你有帮助。
