我需要一个问题的帮助,我试图制作一个卡旋转木马,该卡从我的mysql数据库中获取数据,一切顺利,但是卡在彼此下显示,而不是应该在旋转木马/滑块中显示,任何想法我该如何解决这一问题以使其显示在一行中? 这是我的代码和图片:

您正在</div>循环内关闭2个while,但是它们在while循环之前被打开,您需要将它们添加到{{1}的开头}循环。

添加了一个条件以检查它是否是轮播中的第一个元素,如果是,则根据documentation的要求添加while类。

  

需要初始活动元素.active类需要添加到   其中一张幻灯片。否则,旋转木马将不可见。

我建议作为答案的代码使它更具可读性,这使得防止此类问题变得容易得多。缩进可以帮助您清楚地了解块/循环的起始位置和结束位置。

替换:

active

使用:

<div class="container p-t-0 m-t-2 carousel-inner">
         <div class="row row-equal carousel-item active m-t-0">
             <div class="col-md-4">
    <?php

      $sql = "SELECT * FROM users;";
      $results = mysqli_query($conn, $sql);
      $resultCheck = mysqli_num_rows($results);

      if ($resultCheck > 0){
        while ($row = mysqli_fetch_assoc($results)) {


          //echo '<tr><th scope="row">'.$row['user_id'].'</th><td>'.$row['user_last']."</td><td>".$row['user_uid']."</td></tr>";
          /*echo '<div class="card" style="width: 18rem;">';
          echo '<img class="card-img-top" src="'.$row['avatar'].'" alt="Card image cap">';
          echo '<div class="card-body">';
          echo '<h5 class="card-title">'.$row['user_first'].' '.$row['user_last'].'</h5>';
          echo '<p class="card-text">'.$row['card_text_profil'].'</p>';
          echo '<a href="'.$row['profil_link'].'" class="btn btn-primary">Profil site</a>';
          echo '</div>';
          echo '</div>';*/
          echo '<div class="card" style="width: 18rem;">';
          echo '<div class="card-img-top">';
          echo '<img class="img-fluid" src="'.$row['avatar'].'" alt="Carousel">';
          echo'</div>';
          echo '<div class="card-body">';
          echo '<h5 class="card-title">'.$row['user_first'].' '.$row['user_last'].'</h5>';
          echo '<p class="card-text">'.$row['card_text_profil'].'</p>';
          echo '<a href="'.$row['profil_link'].'" class="btn btn-primary">Profil site</a>';
          echo '</div>';
