Blade 模板布局结构

Question

我需要为每 3 个附件创建一行。像

  @foreach($email->attachment as $attach)
     <div class="row">
       <div class="col-lg-4"></div>
       <div class="col-lg-4"></div>
       <div class="col-lg-4"></div>
    </div>
@endforeach 

   <div class="row">
       <div class="col-lg-4">1st attachment</div>
       <div class="col-lg-4">2nd attachment</div>
       <div class="col-lg-4">3rd attachment</div>
  </div>
  <div class="row">
      <div class="col-lg-4">4th attachment</div>
      <div class="col-lg-4">5th attachment</div>
      <div class="col-lg-4">6th attachment</div>
</div>

等等！我已经搜索了这个问题，但只找到 This link 但它实际上与我的观点不同。谢谢

Answer 1

Use array_chunk - 它是为每个目的而设计的 - 所以你可以将数组切割成子大小并循环遍历每个组

@foreach (array_chunk($email->attachment->toArray(), 3, true) as $array)
    <div class="row">
    @foreach($array as $attachment)
         <div class="col-lg-4">{{ $attachment['id'] }}</div>
    @endforeach
    </div>
@endforeach

并使用@Lukasgeiter 的评论 - 如果它是 Laravel Collection

，您也可以这样做

@foreach ($email->attachment->chunk(3) as $array)
    <div class="row">
    @foreach($array as $attachment)
         <div class="col-lg-4">{{ $attachment->id }}</div>
    @endforeach
    </div>
@endforeach

Answer 2

试试这个，它比生成 2 个数组更快：

  <div class="row">
    @foreach( $email->attachment as $index => $attach)
      <div class="col-lg-4">{{$attach}}</div>
      @if( $index+1 === 0)
        </div><div class="row">
      @endif
    @endforeach
  </div>
