move_uploaded_file错误

littletim

一个很简单的东西。怎么就是出错呢，可能是什么原因呢？
Possible file upload attack! Here's some debugging info: Array ( [file] => Array ( [name] => 20686.gif [type] => image/gif [tmp_name] => /tmp/phpheuRyg [error] => 0 [size] => 10698 ) )


程序如下：
$uploaddir='/opt/apache/htdocs/';
if (move_uploaded_file($_FILES['userfile']['name'], $uploaddir . basename($_FILES['userfile']['name']))) {
print "File is valid, and was successfully uploaded. Here's some more debugging info:\n";
print_r($_FILES);
} else {
print "Possible file upload attack! Here's some debugging info:\n";
print_r($_FILES);
}

最前面加上：
error_reporting(E_ALL);

Notice: Undefined index: userfile in /opt/apache/htdocs/d5/up.php on line 9

未定义userfile?第九行是这个move_uploaded_file($_FILES['userfile']['name'],

怎么回事？菜鸟，见笑了

littletim

我吧userfile改成Filedata了。我前面都有做判断if ($_FILES['Filedata']['size'] <= $MAXIMUM_FILESIZE)。没提示出错啊，为什么到这里说没定义？

littletim

$_FILES['Filedata']前端是通过FLASH传过来的，别人说没有定义input name，这里应该写什么呢？

这个就要靠你自己的。

不知道你的流程是什么。

文件不通过上传，不能用这个函数的。
