Question

好先关闭，我是新来的，所以如果我没有正确发布，请告诉我。我在这个网站上进行了大量搜索，但没有找到我的问题。

我有一个php表单和上传程序，应该根据表单名称字段中的响应以及上传日期上传多个文件并重命名文件（将名称和日期添加到原始文件名）

一切正常除外：只上传一个文件，而不是多个文件。当我写这篇文章的时候，DID可以工作，但是最近我搞砸了。

有人可以告诉我哪里出错了吗？感谢。

以下是表单的代码：

<?php

// make a note of the current working directory relative to root.
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']);

// location of the upload handler
$uploadHandler = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.processor.php';

// max file bytes (2mb)
$max_file_size = 2097152;

// echo

以下是处理：

// upload

                2 => 'html form max file size exceeded', 
                3 => 'file upload was only partial', 
                4 => 'no file was attached');

// check the upload form was actually used. no fancy injection stuff
isset($_POST['submit'])
    or error('woah. you can\'t upload images without the form', $uploadForm);

// check for standard uploading errors
($_FILES[$fieldname]['error'] == 0)
    or error($errors[$_FILES[$fieldname]['error']], $uploadForm);

// check that the file was an HTTP upload, not a sneaky pete
@is_uploaded_file($_FILES[$fieldname]['tmp_name'])
    or error('not an HTTP upload', $uploadForm);

// validation... 
// should run a check to make sure the upload is an image
@getimagesize($_FILES[$fieldname]['tmp_name'])
    or error('only image uploads are allowed', $uploadForm);

//name this file. If not, name by time (remove time function when name works right)
$now = date('m-d-Y');
$photogname = ($_POST['photogname']);
while(file_exists($uploadFilename = $uploadsDirectory.$photogname.$now.'-'.$_FILES[$fieldname]['name']))

{
    $now++;
}

// move the file to final dir (& check perm)

// sucess

// error handler

文件multiple标记的末尾有input个字词。我不知道那是什么，它肯定不是关于HTML 5或其他东西，因为你的文档类型是关于版本4.

检查此代码：

HTML：

<input type="file" name="file[]" class="tag"/>
<input type="file" name="file[]" class="tag"/>
<input type="file" name="file[]" class="tag"/>

PHP：

foreach($_FILES as $file)
{
// check for standard uploading errors
($file['error'] == 0)
    or error($errors[$file['error']], $uploadForm);

// check that the file was an HTTP upload, not a sneaky pete
@is_uploaded_file($file['tmp_name'])
    or error('not an HTTP upload', $uploadForm);

// validation... 
// should run a check to make sure the upload is an image
@getimagesize($file['tmp_name'])
    or error('only image uploads are allowed', $uploadForm);

//name this file. If not, name by time (remove time function when name works right)
$now = date('m-d-Y');
$photogname = ($_POST['photogname']);
while(file_exists($uploadFilename = $uploadsDirectory.$photogname.$now.'-'.$file['name']))

{
    $now++;
}

// move the file to final dir (& check perm)
@move_uploaded_file($file['tmp_name'], $uploadFilename)
    or error('receiving directory insuffiecient permission', $uploadForm);
}

上传多个文件，使用表单数据重命名
