Question

我创建了2个集合（数组），每个集合包含5个项目/事件的数组。

$events = App\get_event_data( $args )
$collection = collect($events['events']);
$event_chunks = $collection->chunk(5);
$event_chunks->toArray();

@foreach ($event_chunks as $chunk)

以上内容的输出

object(Illuminate\Support\Collection)[27632]
protected 'items' => 
  array (size=2)
    0 => 
      object(Illuminate\Support\Collection)[27630]
        protected 'items' => 
          array (size=5)
            ...
    1 => 
      object(Illuminate\Support\Collection)[27631]
        protected 'items' => 
          array (size=5)
            ...

在我的下一个循环中，它只是简单地遍历了数组的每一项1。我需要将5个项目分为另外2个组：
2人一组
3人一组
所以我可以将div围绕每个组。

当前循环：

@foreach ($chunk as $key => $event)
    <div class="item">
       {{ $event['title'] }}
    </div>
@endforeach

我需要什么：

<div class="item-group">
    [item1, item2]
</div>

<div class="item-group">
[item3, item4, item5]
</div>

完整代码：

{{--  Get all events  --}}
@if( $events = App\get_event_data( $args ) )

  @php
    $collection = collect($events['events']);
    $event_chunks = $collection->chunk(5);
    $event_chunks->toArray();
  @endphp

  @foreach ($event_chunks as $chunk)

    <div class="{{ $block }}__flex-grid">

      @foreach ($chunk as $key => $event)
        <div class="item">
          {{ $event['title'] }}
        </div>
      @endforeach

    </div>

  @endforeach

@endif

假设您始终有5件商品，则解决方案可能是：

<div class="item-group">
@foreach (array_slice($chunk->toArray(),0,2) as $key => $event)
    <div class="item">
      {{ $event['title'] }}
    </div>
@endforeach
</div>
<div class="item-group">
@foreach (array_slice($chunk->toArray(),2) as $key => $event)
    <div class="item">
      {{ $event['title'] }}
    </div>
@endforeach
</div>

或者如果要避免代码重复：

@php $chunk = [array_slice($chunk->toArray(),0,2), array_slice($chunk,2)];

@foreach ($chunk as $group)
     <div class="item-group">
     @foreach ($group as $key => $event)
         <div class="item">
             {{ $event['title'] }}
         </div>
    @endforeach
    </div>
@endforeach

如果您不确定或不确定是否有5个，则可能需要更改块/切片的逻辑。
