php - Laravel 在刀片中循环遍历数组

Question

我有以下数组：

$days = [
    ['dow' => 1, 'day' => 'Monday'],
    ['dow' => 2, 'day' => 'Tuesday'],
    ['dow' => 3, 'day' => 'Wednesday'],
    ['dow' => 4, 'day' => 'Thursday'],
    ['dow' => 5, 'day' => 'Friday'],
    ['dow' => 6, 'day' => 'Saturday'],
    ['dow' => 7, 'day' => 'Sunday'],
];

我试图在我的刀片模板中循环它，如下所示：

 @foreach ($days as $day)
       <label>{{$day['day']}}</label>
       {!! Form::text('day_of_wk[$day['dow']].start_time', null, ['class' => 'form-control'])!!}
  @endforeach

但我得到错误：syntax error, unexpected 'dow' (T_STRING)

如何$day['dow']在我的 day_of_wk[] 输入数组中添加值？

Answer 1

  @foreach ($days as $day)
       <label>{{$day['day']}}</label>
       {!! Form::text('day_of_wk['.$day['dow'].'].start_time', null, ['class' => 'form-control'])!!}
  @endforeach

或者

@foreach ($days as $day)
           <label>{{$day['day']}}</label>
           {!! Form::text("day_of_wk[{$day['dow']}].start_time", null, ['class' => 'form-control'])!!}
      @endforeach
