Dropdown No Longer Works

本文关键字：有效不再下拉菜单 | 更新日期: 2023-09-27

这个下拉菜单突然停止工作。Dir没有改变，路径应该没问题。我希望有人能发现我没看到的东西。提前感谢。

  <select name="itinerarypath" type="text" id="itinerarypath">
          <option name="itinerarypath" type="text" id="itinerarypath" value="<?php echo $values['itinerarypath'] ?>" selected="selected"><?php echo $values['itinerarypath'] ?></option>
      <?php 
           foreach(glob(dirname(__FILE__) . '../../../uploads/*') as $filename){
           $filetypes = array("pdf", );
            $filetype = pathinfo($filename, PATHINFO_EXTENSION);
            if (in_array(strtolower($filetype), $filetypes)) {
                 $filename = basename($filename);
           echo "<option value='" . $filename . "'>".$filename."</option>";}
        }
    ?>
    </select>

正如EhsanT所说，我只是缺少了反斜杠

<select name="itinerarypath" type="text" id="itinerarypath">
          <option name="itinerarypath" type="text" id="itinerarypath" value="<?php echo $values['itinerarypath'] ?>" selected="selected"><?php echo $values['itinerarypath'] ?></option>
      <?php 
           foreach(glob(dirname(__FILE__) . '/../../../uploads/*') as $filename){
           $filetypes = array("pdf", );
            $filetype = pathinfo($filename, PATHINFO_EXTENSION);
            if (in_array(strtolower($filetype), $filetypes)) {
                 $filename = basename($filename);
           echo "<option value='" . $filename . "'>".$filename."</option>";}
        }
    ?>
    </select>
