Laravel：如何在刀片中使用 for 和 foreach 显示数据

Question

I want to display data based on the provided template table, using the for and foreach loop, but when else conditions always display an index of its own

This is my expectation:

This is my data:

And this is happening now:

and this is my code:

@for ($i = 0; $i < 7; $i++)

@foreach ($scheduleDetails as $item)
    @if ($i == $item->day)
        <td class="p-1">
            <input name="from[]" value="{{substr($item->from_time,0,-3)}}" id="from{{$i}}" style="width:50px;margin:auto" class="text-center" type="text" readonly>
        </td>
        <td class="p-1">
            <input name="until[]" value="{{substr($item->until_time,0,-3)}}" id="until{{$i}}" style="width:50px;margin:auto" class="text-center" type="text" readonly>
        </td>
    @else
        <td>{{$i}}</td>
    @endif
@endforeach

@endfor

Thanks..

Try this, using keyBy function by making day column as index from the result of $scheduleDetails

@php $newScheduleDetails = $scheduleDetails->keyBy('day'); @endphp
@for ($i = 0; $i < 7; $i++)
   @if($newScheduleDetails->has($i))
       <td class="p-1">
            <input name="from[]" value="{{$newScheduleDetails->get($i)->from_time }}" id="from{{$i}}" style="width:50px;margin:auto" type="text">
        </td>
        <td class="p-1">
            <input name="until[]" value="{{$newScheduleDetails->get($i)->until_time }}" id="until{{$i}}" style="width:50px;margin:auto" type="text">
        </td>
   @else
        <td>{{$i}}</td>
        <td>{{$i}}</td>
   @endif
@endfor
