Question

我正在尝试将多个文件上传到多个文件夹中。不幸的是，收效甚微。

非常感谢任何帮助

我有两个表单字段：

<input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max; ?>" />
<input name="menu" type="file" class="input_event noBorder" title="Upload Menu" />


<input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max; ?>" />
<input name="img" type="file" class="input_event noBorder" title="Upload Img" />

我想使用一个上传图片，另一个上传pdf和/或word文档。我还希望将这两个文件保存到相应的文件夹中（/ imgs和/ docs）。

我尝试过的一些事情

尝试过两个，每个都指向正确的路径
尝试了多个类来处理每个文件
已将数组括号添加到输入名称字段（例如：name="menu[]"）

我想我需要改变班级本身的某些事情;然而，我正在学习PHP，这个课程是从3本书，几十个Google搜索以及我在堆栈中找到的一些帖子拼凑而成的。

正是我需要改变的东西还远远超出了我。

页面PHP代码的相关部分：

$max = 400000;
if (isset($_POST['submit'])) { //MAIN IF STATEMENT  

$destination = './uploads/menus_up/';
try {
$upload = new Upload_File($destination);
$upload->move();
$result = $upload->getMessages();
} catch (Exception $e) {
echo $e->getMessage();
}

Answer 1

我会采用稍微不同的方法：在创建对象时将特定文件发送到构造函数：

$upload = new Upload_File($_FILES['menu'], $destination);

然后，您将获得课程中所需的所有信息，而无需从班级中访问全局变量。

然后，您可以遍历$_FILES数组以添加每个文件或将其放在不同的类中。

这需要在课堂上进行一些改写，但这样可以使其更加灵活，满足您的需求。

<强>解决

所以......对于未来可能会遇到这种情况的人来说，这是一个不太优雅但最终有效的解决方案。

pathinfo($string, PATHINFO_EXTENSION)  FTW!

我为我的processFile方法和Wallah添加了排序机制！

protected function processFile($filename, $error, $size, $type, $tmp_name, $overwrite) {
$OK = $this->checkError($filename, $error);
if ($OK) {
  $sizeOK = $this->checkSize($filename, $size);
  $typeOK = $this->checkType($filename, $type);
  if ($sizeOK && $typeOK) {
    $name = $this->checkName($filename, $overwrite);

    /************************ADDED HERE************************************/
    if (pathinfo($filename, PATHINFO_EXTENSION) == 'pdf' || 'doc' || 'docx'){
        $this->_destination = './uploads/menus_up/';
    if (pathinfo($filename, PATHINFO_EXTENSION) == 'png' || 'jpeg' || 'gif'){
        $this->_destination = './uploads/eventBG_up/';  
    /**********************************************************************/

    $success = move_uploaded_file($tmp_name, $this->_destination . $name);
    if ($success) {
        $message = "$filename uploaded successfully";
        if ($this->_renamed) {
          $message .= " and renamed $name";
        }
        $this->_messages[] = $message;
    } else {
      $this->_messages[] = "Could not upload $filename";
     }
   }
  }
 }  
}
}
