Question

我在laravel有一个项目。数据库是mongodb。我正在使用包来连接laravel和mongo“https://github.com/jenssegers/laravel-mongodb”。在我的项目中，我有一个预订列表页面。 jQuery Datatables服务器端功能用于分页，搜索和排序。目前的分页和搜索工作正在进行，但排序不起作用。我收到一些错误，请检查附件。我认为这是查询中排序部分的问题。请检查以下代码并帮助我。感谢。

bookings.blade.php

$('#booking_data').DataTable({
                "processing": true,
                "serverSide": true,
                "ajax": {
                    "url": '{{ route('bookings.datatables') }}',
                    "dataType": "json",
                    "type": "POST",
                    "data":{ _token: "{{csrf_token()}}"}
                },
                "columns": [

问题在于BookingController。

$columns       = array('invoice_number', 'checkin_from', 'reserve_to', 'beds', 'dormitory', 'sleeps', 'status', 'payment_status', 'payment_type', 'total_prepayment_amount', 'txid');
...
$order         = $columns[$request->input('order.0.column')];

DataTable会在请求中发送列名，而不是key，因此您无法以这种方式使用它。也许你可以用这个代替：

$order = $request->input('order.0.column');

如果要对有效列进行验证，可以使用in_array()函数。

如何使用laravel，mongo和datatables对多个列进行排序？
