序列号没有增加

Question

Here is my code,

  <tbody>
    <?php $j = 1; ?>
    @foreach($items as $item)
    <tr>
      <td class="text-right">{{ $j }}</td>
      <td>{{ $item->product_name }}</td>
      <td>{{ $item->product_name2 }}</td>
      <td>{{ $item-> quantity}}</td>
      <td class="text-center"><a href="{{ route('Conversion.edit', $item->id) }}" class="btn btn-warning"><span class="glyphicon glyphicon-pencil" aria-hidden="true"></span></a></td>
      <td class="text-center">
        {!! Form::open([
          'method' => 'DELETE',
          'route' => ['Conversion.destroy', $item->id]
          ]) !!}

          {!! Form::button('<i class="glyphicon glyphicon-remove"></i>', array('type' => 'submit', 'class' => 'btn btn-danger')) !!}

          {!! Form::close() !!}
        </td>
      </tr>
      @endforeach
      <?php $j++; ?>
    </tbody>

When i execute this code, the serial number remains 1 for addition of more values.. For each and every value that has been added was with serial number 1.. How to get the increment of values like 2,3,4.. so on??

Answer 1

while you are using foreach why use extra variable you can do that with foreach like that

@foreach($items as $key =>$item)                    
    <tr>
      <td class="text-right"> {{$key+1}} </td>
      <td>{{ $item->product_name }}</td>
      <td>{{ $item->product_name2 }}</td>
      <td>{{ $item-> quantity}}</td>
      <td class="text-center"><a href="{{ route('Conversion.edit', $item->id) }}" class="btn btn-warning"><span class="glyphicon glyphicon-pencil" aria-hidden="true"></span></a></td>
      <td class="text-center">
        {!! Form::open([
          'method' => 'DELETE',
          'route' => ['Conversion.destroy', $item->id]
          ]) !!}

          {!! Form::button('<i class="glyphicon glyphicon-remove"></i>', array('type' => 'submit', 'class' => 'btn btn-danger')) !!}

          {!! Form::close() !!}
        </td>
      </tr>
      @endforeach

but if want to use your method then just simply put <?php $j++; ?> inside the foreach loop
