我看着这个例子做，但是当选中一个文件，点击上传的时候却出现Error 6 ，我在php.ini中的将 upload_tmp_dir 启动设置为 upload_tmp_dir ="C:\WX" 点击上传却显示Invalid file，同样无法上传文件，请指点。

回复讨论(解决方案)

一般的情况，是上传保存的目录不可写造成的。你要好好设置一下

index.html代码

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>无标题文档</title></head><body><form action="upload_file.php" method="post"enctype="multipart/form-data"><label for="file">Filename:</label><input type="file" name="file" id="file" /> <br /><input type="submit" name="submit" value="Submit" /></form></body></html>

upload_file.php代码：

<?phpif ($_FILES["file"]["error"] > 0)  {  echo "Error: " . $_FILES["file"]["error"] . "<br />";  }else  {  echo "Upload: " . $_FILES["file"]["name"] . "<br />";  echo "Type: " . $_FILES["file"]["type"] . "<br />";  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";  echo "Stored in: " . $_FILES["file"]["tmp_name"];  }?>

不用修改php.ini 里面的东西，把它还原回去后再试试。

我已经卸载重新安装了，但是依然未能上传文件，不知道到底是哪里的问题，我发现这些开源的软件安装和配置起来都有一定的难度，各种错误也很头疼啊。请问可有解决方法？？

$_FILES["file"]
打印一下这个变量看看什么内容再判断

print_r($_FILES["file"]);exit;

Error: 6
表示上传文件不存在

你最好将 upload_tmp_dir 设置到 D: 即以后的驱动器中
因为 C: 驱动器一般都设置为禁止匿名用户的文件操作

$_FILES['file']['error']
其值为 0，没有错误发生，文件上传成功。

其值为 1，上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值。

其值为 2，上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值。

其值为 3，文件只有部分被上传。

其值为 4，没有文件被上传。

其值为 6，找不到临时文件夹。PHP 4.3.10 和 PHP 5.0.3 引进。

其值为 7，文件写入失败。PHP 5.1.0 引进。

看报错的话,应该是临时文件夹没有写权限或者不存在

版主请帮帮忙，我看这个blog的时候，http://blog.csdn.net/k8080880/article/details/6193060，我已经把
IUSR_7195F2AD8ACB471 和 IWAM_7195F2AD8ACB471 都给D：// r// 目录添加到权限，php.ini修改upload_tmp_dir ="D:/r" 为什么上传文件的时候依然显示错误ERROR :6 ,根据“wzb0712”说的，其值为 6，找不到临时文件夹。PHP 4.3.10 和 PHP 5.0.3 引进。总是无法解决这种问题，请版主帮忙看看。

安装一个wamp试试。

可能跟文件大小有关，报错是临时文件不存在，那就是写入问题了

我试了很多方法依然不凑效啊
代码在这里http://www.w3school.com.cn/php/php_file_upload.asp

为什么会发生这样的情况？请问如何解决？牛人指点指点。

http://yunpan.cn/QUFvS5gnx2Wzi 这是我之前写的，文件上传函数，很简单，之前写的了，你可以参考一下

同样是出错，不知道为什么会这样，我相信你的代码和w3school是没问题的，可能是系统问题还是什么其他的原因，我换个系统再试试看。。
