我正在尝试上传多个文件到多个文件夹。不幸的是，收效甚微。多个文件上传到多个文件夹 - PHP
任何帮助，将不胜感激
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" />
我想用一个上传图像和其他上传PDF格式的和/或Word文档。 我还想将这两个文件保存到相应的文件夹（/ imgs和/ docs）中。
有些事情我已经尝试
- 都试图拥有其中的两个，每个指向正确的路径
- 试图多类来处理
- 添加阵列支架固定到每个文件输入名称字段（例如：
name="menu[]"）
我想我需要改变类中的某些东西;然而，我正在学习PHP，这个课程是从3本书，数十个谷歌搜索以及我在这里找到的一些帖子拼凑在一起的。
正是我需要改变的地方仍然远远超出了我。
的对网页PHP代码相关部分：
$max = 400000;
if (isset($_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();
}

这是很多上传文件的代码。你应该尝试缩小问题的范围。 – jeroen
是它有点过分;但我正在修补，然后认为我会创建一个类，一次做所有的事情......错误处理，文件重命名，覆盖保护等。不可否认，我有点被带走了。但是，现在我花了这么多时间在这件事上，我想完全完成它。不幸的是遇到了障碍。大声笑 – kash101
这是没有问题的，只是让基本工作和添加功能（或方法调用），因为你得到每一步工作。现在你应该摆脱它的大部分（至少在这里），并发布一个错误发生地点的例子。那究竟出了什么问题。 – jeroen
