Foreach循環回波組錯誤

Question

在這裏，我有一個foreach循環經歷客戶端可查看的日期日曆。在第一個循環中，我將$ i作爲一個變量等於0.然後，我給出規則說明如果$ i等於0或可以被3整除然後回顯div類組。但是，如果循環在$ i等於1時退出，或者被2整除以關閉類組並繼續向下。出於某種原因，當我有1或2個條目時，該組無法正確關閉，並且內部捕獲了以下div。請你看看這個代碼，看看我在哪裏搞亂...

你遇到問題，因爲你過早地增加你的櫃檯。下面的代碼被清理了一下，但基本的想法是，在檢查是否需要關閉div標記之前，您不應該增加計數器。

<div class="past_events grid-calender"> 
    <?php $i = 0; ?> 
    @foreach($past as $event) 
     @if ($i == 0) 
    <div class="group_loop_first"> 
     @elseif ($i % 3 === 0) 
    <div class="group_loop"> 
     @endif 
     <div class = "p_date grid-date"> 
      <!-- rest of html --> 
     </div> 

     @if ($i % 3 === 0) 
    </div> 
     @endif 
     <?php $i++; ?> 
    @endforeach 
</div> 

<div class="future_events grid-calender"> 
    <?php $i = 0; ?> 
    @foreach($future as $event) 
     @if ($i % 3 === 0) 
    <div class="group_loop"> 
     @endif 
     <div class = "p_date grid-date"> 
      <!-- rest of html --> 
     </div> 
     @if ($i % 3 === 0) 
    </div> 
     @endif 
     <?php $i++; ?> 
    @endforeach 
</div>
