Question

我想在视图中访问查询中的值。

$bookings = DB::table('bookings')
            ->join('staffs', 'staffs.id' , '=', 'bookings.staff_id')
            ->join('customers', 'customers.id' , '=', 'bookings.customer_id')
            ->select('bookings.id', 'bookings.start_time',  'bookings.end_time', 'bookings.service', 'staffs.name as Staff-Name',  'customers.name as Customer-Name')
            ->orderBy('customers.name', 'desc')
            ->get();

        return view('booking.index')->with('bookings', $bookings);

这很容易理解。我想要做的是，我想获得start_time，end_time在预订表中，名称是员工表也在客户表中名称。

现在我正在做：

@foreach($bookings as $booking)
  {{ $booking->start_time }}
  {{ $booking->end_time }} 
  {{ $booking->name }} // name column which is in customers table
@endforeach

但这些事似乎不起作用。

Answer 1

这都是因为您使用的是列名而不是您设置的别名。

看看它，例如customers.name被命名为客户名称。

->select('bookings.id', 'bookings.start_time',  'bookings.end_time', 'bookings.service', 'staffs.name as Staff-Name',  'customers.name as Customer-Name')

如果您想访问数据，您需要这样做：

@foreach($bookings as $booking)
  {{ $booking->start_time }}
  {{ $booking->end_time }} 
  {{ $booking->Customer-Name }} // name of alias
@endforeach

无论如何我不认为别名中的破折号是好的解决方案，你应该使用下划线。 (customers.name as Customer_Name)和$booking->Customer_Name

Answer 2

试试这个

$bookings = DB::table('bookings')
        ->join('staffs', 'staffs.id' , '=', 'bookings.staff_id')
        ->join('customers', 'customers.id' , '=', 'bookings.customer_id')
        ->select('bookings.id', 'bookings.start_time',  'bookings.end_time', 'bookings.service', 'staffs.name as Staff-Name',  'customers.name as Customer-Name')
        ->orderBy('customers.name', 'desc')
        ->get();

        return view('booking.index')->with(compact('bookings'));

Answer 3

$ bookings包含一系列数据。您可以在视图中打印这些..

@foreach($bookings as $booking)
    {{$booking->start}}
    {{$booking->end_time}}
@endforeach

无法从控制器访问值（Laravel 5.3）
