[解决办法]
这一行 $name=$filepath.$_FILES["upload"]["name"];
第一个文件上传的name="file" , 没有"upload" 啊.
[解决办法]
1.
if (!$_POST["upfile"]&&$_FILES["upfile"]["name"]=="")
==>
if ($_FILES["upfile"]["name"]=="") //这样就能判断是否选择文件了
2.
$name=$filepath.$_FILES["upload"]["name"];
==》
$name=$filepath.$_FILES["upfile"]["name"];
3. 如果你的文件存在了。while循环不就成了死循环了吗，可以改为：
if(file_exists($name))
{
$temp=explode(".", $name);
$name=$temp[0]."0".".".$temp[1];
}
4. $content=$_FILES["upfile"]["name"]."
[解决办法]
".$owner."
[解决办法]
".$describe."
[解决办法]
".$time."\n";
