如何使用foreach獲得forloop工作

Question

我正在運行查詢以從搜索頁上的數據庫恢復產品。這是我想做的事：

• 我想一些文本放置6和每一頁上的18個分頁結果的12後。

• 如果搜索運行不到12個結果回來，我想告訴我如何在工作後的6只

文字我的環我的foreach內？

這是我的代碼。代碼應該放在哪裏？

爲：

@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

試試這個。

@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

我認爲要做到這一點的最好辦法是把這些組合成一個用於與if條件語句每個循環。

@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 

編輯：我打開此線程，直到後來才發佈答案。看起來adamyi在那個時候發佈了非常類似的答案。他更正確，因爲他修正了你的數組索引問題，我忽略了這些。
