如何根据其值在HTML单元格中添加类

Question

我有以下循环，其中我从查询中提取值并用表编写表，在该字段中，我需要根据从发货日期到今天为止所经过的天数，更改年龄的字段

我已经在CSS中尝试过了[data-age> 180]，但是我只遇到错误，而且找不到与我的需求类似的情况，另外，id喜欢在循环内进行操作，而不是另外的代码，因为它弄乱了我的视线

@foreach($shipments as $shipment)

  <tr>

    <td data-title="id">{{$shipment->id}}</td>

    <td class=tracking data-title="tracking">{{$shipment->tracking}}</td>

    <td data-title="PartNumber">{{$shipment->PartNumber}}</td>

    <td data-title="DateShipped">{{$shipment->DateShipped}}</td>

    <td 

      data-title="age" 

      data-age="{{

        (int) floor(

          (time() - strtotime($shipment->DateShipped)) 

          / (60 * 60 * 24)

        )

      }}"

    >{{

      (int) floor(

        (time() - strtotime($shipment->DateShipped)) / (60 * 60 * 24)

      )

    }} days

    </td>

    <td data-title="Qtyorder">{{$shipment->Qtyorder}}</td>

    <td data-title="QtyShipped">{{$shipment->QtyShipped}}</td>

    <td data-title="QtyBckorder">{{$shipment->QtyBckorder}}</td>

    <td data-title="purchaseOrder">{{$shipment->purchaseOrder}}</td>

    <td data-title="OrderNumber">{{$shipment->OrderNumber}}</td>

    <td data-title="paperwork">{{$shipment->paperwork}}</td>

    <td data-title="VMIreceived">{{$shipment->VMIreceived}}</td>

    <td data-title="VMIticketNumber">{{$shipment->VMIticketNumber}}</td>

    <td data-title="VMILRB">{{$shipment->VMILRB}}</td>

    <td>

      <a 

        href="{{ route('shipment.edit',$shipment->id)}}" 

        class="btn btn-primary"

      >

        Edit

      </a>

    </td>

    <td>

      <form action="{{ route('shipment.destroy', $shipment->id)}}" method="post">

        @csrf

        @method('DELETE')

        <button class="btn btn-danger" type="submit">Delete</button>

      </form>

    </td>

  </tr>

@endforeach

Answer 1

未经测试，但是您可以尝试以下操作：@foreach($shipments as $shipment)&nbsp; @php&nbsp; &nbsp; $time_passed = $shipment->DateShipped->diffInSeconds(now());&nbsp; @endphp&nbsp; <tr>&nbsp; &nbsp; <td class="{{ time_passed > some_number ? 'class_value_if_true' : 'class_value_if_false' }}">&nbsp; &nbsp; &nbsp; {{ $time_passed }}&nbsp; &nbsp; </td>&nbsp; </tr>@endforeach

Answer 2

尝试一行if语句{{&nbsp;$condition&nbsp;?&nbsp;value&nbsp;if&nbsp;true&nbsp;:&nbsp;value&nbsp;if&nbsp;false&nbsp;}}
