Laravel 5.4 检查块是否是第一个块

Question

我正在尝试设置一个条件来检查该块是否是第一批块。

任何人都知道如何检查块 ID 或类似的东西，例如：

@foreach($item->chunk(3) as $item_chunk
    @if(chunk is first chunk)
        <div class="carousel-item active">
    @else
        <div class="carousel-item">
    @endif

    @foreach($item_chunk as $item)
        {{-- Do something --}}
    @endforeach 
@endforeach

如果有人知道检查分块列表是否在第一位的方法，将不胜感激。

Answer 1

您可以使用 $loop variable 检查循环。

@foreach($item->chunk(3) as $item_chunk)
    @if($loop->first)
        <div class="carousel-item active">
    @else
        <div class="carousel-item">
    @endif

    @foreach($item_chunk as $item)
        {{-- Do something --}}
    @endforeach 
@endforeach

Answer 2

对于滑块

            <div class="carousel-inner">
              @foreach($item_hr as $count => $valuetopproducts)
                <div class="item {!! $count == 0 ? 'active' : '' !!}">
                      <a href="{{ url('asset_details')}}/{{$valuetopproducts->assetid}}"><img src="{{Storage::url('wp/thumbnail')}}/{{$valuetopproducts->imagename}}" class="img-responsive" alt="{!! \Illuminate\Support\Str::words($valuetopproducts->assetname, 10,'...')  !!}"></a>
                </div>
              @endforeach
            </div>
