public function complete(Request $request, $id){
    $order = Order::find($id);

    // Update the Order
    $value =  $request->input('table');
    $number = DB::table('tables')->where('number' , '=' , $value)->update(['status' => "Fine"]);
    $order->update(['status' => 'CompletedOrders']);

    return redirect()->route('servedorders');
}

我给表输入赋值了一个变量。然后我尝试将这个变量与表中的列进行匹配。但我无法将值更新为“free”。我的询问有什么问题吗？
所有价值都来自何处。

@foreach($orders as $order)
                @if($order->status == "OrdersServed")
                    <div class="panel panel-default">
                        <div class="panel-body">
                            <ul class="list-group" >

                                <li class="list-group-item" style="background-color: #467aeb">

                                    @foreach($order->cart->items as $item)
                                        <span class="label label-success"><p style="font-size: 15px; color: #051942"><b>{{$item['qty'] }} {{ $item['item']['name'] }} </b></p></span>

                                    @if($order->status == 'OrdersServed')

                                @endif
