Question

我目前正试图将它放在我的数据库存储图像名称（如slider1.jpg）的位置，然后我从我的数据库中检索它，但问题是当我从表中选择* all时仅显示表格中的第一个链接。关于如何在我的代码中修复此问题的任何想法？

继承我的PHP：

    <?php
        //Gets Links
    $stmt = $DB_con->prepare('SELECT * FROM slider');
    $stmt->execute();
if($stmt->rowCount() > 0)
{
     $row=$stmt->fetch(PDO::FETCH_ASSOC);

        extract($row);
}

?>

而我的旋转木马滑块。

 <header>
      <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
        <ol class="carousel-indicators">
          <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
          <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
          <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
        </ol>
        <div class="carousel-inner" role="listbox">
          <!-- Slide One - Set the background image for this slide in the line below -->
          <div class="carousel-item active" style="background-image: url('images/slider/<?php echo $row['link'];?>')">
            <div class="carousel-caption d-none d-md-block">
              <h3>First Slide</h3>
              <p>This is a description for the first slide.</p>
            </div>
          </div>
          <!-- Slide Two - Set the background image for this slide in the line below -->
          <div class="carousel-item" style="background-image: url('images/slider/<?php echo $row['link'];?>')">
            <div class="carousel-caption d-none d-md-block">
              <h3>Second Slide</h3>
              <p>This is a description for the second slide.</p>
            </div>
          </div>
          <!-- Slide Three - Set the background image for this slide in the line below -->
          <div class="carousel-item" style="background-image: url('images/slider/<?php echo $row['link'];?>')">
            <div class="carousel-caption d-none d-md-block">
              <h3>Third Slide</h3>
              <p>This is a description for the third slide.</p>

          </div>
        </div>
        <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">

          <span class="sr-only">Previous</span>
        </a>
        <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
          <span class="carousel-control-next-icon" aria-hidden="true"></span>
          <span class="sr-only">Next</span>

      </div>
    </header>

您需要在结果上使用循环，以便您可以使用数据库查询中的新$行构建每张幻灯片：

<?php
// build a clean array of slides from the db grab
$stmt = $DB_con->prepare('SELECT * FROM slider');
$stmt->execute();
$slides = [];
if($stmt->rowCount() > 0) {
    $slides = $stmt->fetchAll(PDO::FETCH_ASSOC);
}
?>

.... starter html ....

    <ol class="carousel-indicators">
       <?php foreach($slides as $i => $slide) { ?>
          <li data-target="#carouselExampleIndicators" 
              data-slide-to="<?php echo $i;?>" 
              class="<?php echo (!$i?'active':'');?>"></li>
       <?php }?>
    </ol>

.... more html ....

<div class="carousel-inner" role="listbox">
   <?php foreach($slides as $i => $slide) { ?>

      <div class="carousel-item <?php echo (!$i?'active':'');?>" 
           style="background-image: url('images/slider/<?php echo $slide['link'];?>')">
        <div class="carousel-caption d-none d-md-block">
          <h3><?php echo $slide['slide_name'];?></h3>
          <p><?php echo $slide['slide_desc'];?></p>
        </div>
      </div>

   <?php } ?>
</div>

.... the rest of your html output ....
