如何使用foreach获得forloop工作

Question

我正在运行查询以从搜索页上的数据库恢复产品。这是我想做的事：

• 我想一些文本放置6和每一页上的18个分页结果的12后。

• 如果搜索运行不到12个结果回来，我想告诉我如何在工作后的6只

文字我的环我的foreach内？

这是我的代码。代码应该放在哪里？

为：

@for ($i = 0; $i < count($products); $i++) 
    @if (in_array($i,array(6,12,18)) && count($products) >= 12) 
     <h2> example code </h2> 
    @elseif ($i == 6 && count($products) < 12) 
     <h2>example</h2> 
    @endif 
@endfor 

的foreach：

@foreach ($products as $product) 

       <div class="row sing"> 
       <div class="col-md-3"> 
        <a href="{{route('products.single',$product->slug)}}"><div class="img"><div class=" container img-s" style="background-image:url('{{ asset('images/' . $product->image)}}'); background-repeat: no-repeat; 
           background-size: cover; 
           background-position: center center;"></div></div></a> 
       </div> 
       <div class="col-md-9"> 
        <div class="info-productsearch"> 
        <div class="name-holder"> 
        <h4>{{$product->productname}}</h4> 
         @if(Count($product->reviews) >0) 
         <p>Rated : {{number_format($product->reviews->avg('ratings'),2)}}/ 5, from {{$product->reviews->count()}} reviews</p> 
         @else 
          <p>Rated : Yet To Be Reviewed</p> 

         @endif 

        </div> 

        <p class="location-det"><i class="icon-map-marker"></i> {{$productt->producttypes}}, {{$sight->productrefcode}}</p> 
        <p>{{substr(strip_tags($product->prodinfo), 0, 325)}}<a class="find-out-more" href="{{route('products.single',$product->slug)}}"> (...Find out more)</a></p> 
       </div> 
       </div> 

    </div> 
    @endforeach

试试这个。

@foreach ($products as $index => $product) 
    <div class="row sing"> 
     <div class="col-md-3"> 
      <a href="{{route('products.single',$product->slug)}}"><div class="img"><div class=" container img-s" style="background-image:url('{{ asset('images/' . $product->image)}}'); background-repeat: no-repeat; background-size: cover; background-position: center center;"></div></div></a> 
     </div> 
     <div class="col-md-9"> 
      <div class="info-productsearch"> 
       <div class="name-holder"> 
        <h4>{{$product->productname}}</h4> 
        @if(Count($product->reviews) >0) 
         <p>Rated : {{number_format($product->reviews->avg('ratings'),2)}}/ 5, from {{$product->reviews->count()}} reviews</p> 
        @else 
         <p>Rated : Yet To Be Reviewed</p> 
        @endif 
       </div> 
       <p class="location-det"><i class="icon-map-marker"></i> {{$productt->producttypes}}, {{$sight->productrefcode}}</p> 
       <p>{{substr(strip_tags($product->prodinfo), 0, 325)}}<a class="find-out-more" href="{{route('products.single',$product->slug)}}"> (...Find out more)</a></p> 
      </div> 
     </div> 
     @if (in_array($index, array(5,11,17)) && count($products) >= 12) 
      <h2> example code </h2> 
     @elseif ($index == 5 && count($products) < 12) 
      <h2>example</h2> 
     @endif 
    </div> 
@endforeach

我认为要做到这一点的最好办法是把这些组合成一个用于与if条件语句每个循环。

@foreach ($products as $product) 
<div class="row sing"> 
      <div class="col-md-3"> 
       <a href="{{route('products.single',$product->slug)}}"><div class="img"><div class=" container img-s" style="background-image:url('{{ asset('images/' . $product->image)}}'); background-repeat: no-repeat; 
          background-size: cover; 
          background-position: center center;"></div></div></a> 
      </div> 
      <div class="col-md-9"> 
       <div class="info-productsearch"> 
       <div class="name-holder"> 
       <h4>{{$product->productname}}</h4> 
        @if(Count($product->reviews) >0) 
        <p>Rated : {{number_format($product->reviews->avg('ratings'),2)}}/ 5, from {{$product->reviews->count()}} reviews</p> 
        @else 
         <p>Rated : Yet To Be Reviewed</p> 


        @endif 

       </div> 

       <p class="location-det"><i class="icon-map-marker"></i> {{$productt->producttypes}}, {{$sight->productrefcode}}</p> 
       <p>{{substr(strip_tags($product->prodinfo), 0, 325)}}<a class="find-out-more" href="{{route('products.single',$product->slug)}}"> (...Find out more)</a></p> 
      </div> 
      </div> 
@if (in_array($i,array(6,12,18)) && count($products) >= 12) 
    <h2> example code </h2> 
@elseif ($i == 6 && count($products) < 12) 
    <h2>example</h2> 
@endif 

编辑：我打开此线程，直到后来才发布答案。看起来adamyi在那个时候发布了非常类似的答案。他更正确，因为他修正了你的数组索引问题，我忽略了这些。
