Laravel在后端返回数据但不在前端

Question

我有orders表，我将订单数据保存在product_name列中作为json，我可以在管理面板中获取订单数据但是当我尝试在前端使用相同的代码时也显示向用户订购详细信息，它会返回错误。

  

为foreach（）提供的参数无效

的后端

public function index()
{
  $orders = Order::orderby('id', 'desc')->paginate(10);
  return view('admin.orders.index', compact('orders'));
}

admin index

@foreach($orders as $order)
  {{$order->payment_id}}
  {{$order->total_items()}}
@endforeach

admin edit page（了解我如何从product_name列获取详细信息）

public function edit($id, Request $request)
{
  $order = Order::find($id);
  $statuses = Orderstatus::all();
  $addresses = Address::where('user_id', $order->user_id)->get();
  return view('admin.orders.edit', compact('order', 'statuses', 'addresses', 'json'));
}

edit blade

<p>#{{$order->payment_id}}</p>
@foreach($order->product_name as $data)
  {{ $data['name'] }}
  {{$data['quantity']}}
  {{number_format($order->total_price(), 0)}}
@endforeach

前端

public function orders(Request $request)
{
    $orders = Order::where('user_id', '=', Auth::user()->id)->orderby('id', 'desc')->paginate(5);
    return view('front.orders', compact('orders'));
}

in blade

@foreach($orders as $order)
  #{{$order->ordernu}}
  @foreach($order->product_name as $data)
    <li>{{ $data['name']}}</li>
  @endforeach
@endforeach

然后我收到此错误：

  

为foreach（）提供的参数无效

有什么想法吗？

更新

dd($orders)结果

要获得所需的结果，您需要遍历orders.items，因为它是一个分页器对象

foreach($orders.items as $order)
{
  //rest of code
}
