select 值未通过

Question

有人能告诉我为什么它没有通过吗？除了 select 选项值外，所有其他值都被传递。文件完全按照我的意愿得到更新。但是专辑 ID 没有按照我的意愿分配 :( .

HTML 页面代码：

    <form  action="" method="post" enctype="multipart/form-data" >                          
    <label>Select Image:</label>
    <input type="file" aria-required="true" size="30" id="file" name="files[]" multiple="multiple" />
    <?php if(isset($_GET['al'])){ ?>
    <label>Album(required):</label>                                                                             
    <select name='album'  id='album' aria-required="true">     
    <?php 
    $query_album = "SELECT * FROM  `albums` ORDER BY `id` DESC ";
    $result_m = $conn->query($query_album);
    if ($result_m->num_rows > 0) {
       // output data of each row
       while($item_a = $result_m->fetch_assoc()) { 
            $value= $item_a['id'];?>
            <option value='<?php echo $value; ?>'>
            <?php echo $item_a['title']; ?>
            </option>    
       <?php 
       }
    } ?>                                
    </select>
  <?php } ?>
  <label>Image Title :</label>
  <input type="text" aria-required="true" size="30" value="" name='title' id='title'>    
  <label> Image Description :</label>
  <input type="text" aria-required="true" size="30" value="" name='desc' id='desc'>    
  <button type="submit" value="Upload!" class="soc-icon soc-icon-small soc-icon-alt fa fa-floppy-o">    
  </button>&nbsp;&nbsp;&nbsp;
  <button type="reset" name="reset" class="soc-icon soc-icon-small soc-icon-alt fa fa-refresh">
  </button>&nbsp;&nbsp;&nbsp;    
  <input type="hidden" name="album" id="album" value="<?php echo $album; ?>"> 
  <a href="gallery.php" class="soc-icon soc-icon-small soc-icon-alt fa fa-arrow-left"></a>
  </form>

PHP 来自上传页面的代码，其中值被传递给...除了相册 ID 之外的所有其他值都被传递。有人可以帮我弄清楚我做错了什么吗？

  <?php
  include 'DBConfig.php';
  require 'imageconfig.php';
  require 'img_functions.php';
  if(isset($_FILES['files'])){

        $image_title=$_POST['title'];   
        $image_desc=$_POST['desc']; 
        $errors= array();
        foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
            $file_name = $key.$_FILES['files']['name'][$key];
            $file_size =$_FILES['files']['size'][$key];

                        mkdir("$desired_dir", 0700);        // Create directory if it does not exist

                $result = mysqli_query($conn, $query);              
            }else{

        }
        if(empty($error)){
            header('Location:gallery.php');

您正在用另一个同名的输入覆盖您的输入：

<select name='album'  id='album' aria-required="true">
...
<input type="hidden" name="album" id="album" value="<?php echo $album; ?>">
