【问题描述】：
我对此有点困惑。如何使用ajax在laravel中保存多行数据？这个想法是添加产品，当单击提交按钮时，我想将表数据保存在数据库中。我收到一个错误，因为我的控制器中为 foreach 提供的参数无效。
这是我的带有脚本的刀片模板。

dataType: "json",
success: function (data) {
console.log(data);
}
});
});
</script>
</html>这是我存储数据的控制器。
public function store(Request $request)
{
$invoices = [];
foreach ($request->input('product_name') as $key => $value) {
$invoices["product_name.{$key}"] = 'required';
$invoices["description.{$key}"] = 'required';
$invoices["price.{$key}"] = 'required';
$invoices["qty.{$key}"] = 'required';
$invoices["amount.{$key}"] = 'required';
$invoices["subTotal.{$key}"] = 'required';
$invoices["discount.{$key}"] = 'required';
$invoices["total.{$key}"] = 'required';
}
$validator = Validator::make($request->all(), $invoices);
if ($validator->passes()) {
foreach ($request->input("product_name") as $key => $value) {
$invoice = new Invoice;
$invoice->product_name = $request->get("product_name")[$key];
$invoice->description = $request->get("description")[$key];
$invoice->price = $request->get("price")[$key];
$invoice->qty = $request->get("qty")[$key];
$invoice->amount = $request->get("amount")[$key];
$invoice->subTotal = $request->get("subTotal")[$key];
$invoice->discount = $request->get("discount")[$key];
$invoice->total = $request->get("total")[$key];
$invoice->save();
}
}
}
它返回 500 内部服务器错误。
