<div class="contact-form">

      ?> 
      <div class="active item"> 
       <div class="profile-circle" style="background-color: rgba(0,0,0,.2);"> 
       <img class="profile-circle" src="<?php echo base_url(); ?>uploads/images/testimonials/<?php echo $t->picture; ?>" alt="testimonials_image"> 
       </div> 
       <blockquote> 
        <p><?php echo $t->content; ?></p> 
       </blockquote> 
      </div> 
      <?php 
      } 
      ?> 
     </div> 
    </div> 
</div>

這是代碼，其實我知道是什麼錯誤，但我不知道如何糾正它，即在第一次執行時，部門級別必須是活動項目並且在首次執行後，該類別只需要項目。

爲什麼不你在循環中添加一個簡單的計數器？如果爲0，則回顯「有效」。如果你確定這是問題，我可以用代碼回答你。 – GeorgeGeorgitsis

是的，確定是問題所在 –

如果您確信該問題是隻有第一個元素的類"active"，你可以做這樣的事情，在您的foreach：

<div class="carousel-inner"> 
    <?php 
    $counter = 0; 
    //add a counter and check its value in your div. 
    //If it's 0, echo active, otherwise nothing. 
    //In the end of your loop, the counter increases so it won't be 0 again 

    foreach ($testimonials as $t) { 
    //next div will echo "active", if the $counter==0 

     ?> 
     <div class="item <?= ($counter == 0) ? "active" : "" ?>"> 
      <div class="profile-circle" style="background-color: rgba(0,0,0,.2);"> 
       <img class="profile-circle" src="<?php echo base_url(); ?>uploads/images/testimonials/<?php echo $t->picture; ?>" alt="testimonials_image"> 
      </div> 
      <blockquote> 
       <p><?php echo $t->content; ?></p> 
      </blockquote> 
     </div> 
     <?php 

     //increase the $counter, or set it another value in order not to echo "active" again for the next loops 
     $counter++; 
    } 
    ?> 
</div>
