javascript - 使用 php glob() 函数构建 Bootstrap 轮播

Question

我正在拼命尝试构建一个带有 slider 的主页，问题不是页面本身，而是我想从我在 WordPress 上传文件夹中创建的子文件夹中动态获取图像。这是我的代码

<div id="" class="carousel slide" data-ride="carousel">

  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <?php
        $imageDir = "wp-content/uploads/home-carousel";
        $images = glob($imageDir.'/*.{jpg, jpeg, png, gif}');
        $flag=1;
        foreach ($images as $image){
        echo '<div class="item' .($flag?' active':''). '">';
        echo '<img src="'.$image.'" alt=""></div>';
        $flag=0;
        }
      ?>
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

问题是 glob() 函数返回我和空数组。我也尝试过这个

<?php
        $imageDir = wp_upload_dir();
        $images = glob($imageDir['basedir'].'/home-carousel/*.{jpg, jpeg, png, gif}');
        $flag=1;
        foreach ($images as $image){
        echo '<div class="item' .($flag?' active':''). '">';
        echo '<img src="'.$image.'" alt=""></div>';
        $flag=0;
        }
      ?>

但也不起作用。有人能帮我吗？谢谢!!!

使用GLOB_BRACE

$imageDir = wp_upload_dir();
$images = glob($imageDir['basedir'].'/home-carousel/*.{jpg, jpeg, png, gif}', GLOB_BRACE);
