这一行 $name=$filepath.$_FILES["upload"]["name"];
第一个文件上传的name="file" , 没有"upload" 啊.
move_uploaded_file($_FILES["upfile"]["tmp_name"], $name) 后面参数没有带路径
move_uploaded_file($_FILES["upfile"]["tmp_name"], $name) 后面参数没有带路径
他的$name=$filepath.$_FILES["upfile"]["name"];就是这个
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"]."||".$owner."||".$describe."||".$time."\n";
1.
if (!$_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.$_……
谢谢你的帮助,根据这样修改后,确实完成了模块功能...万分感谢.

恩,确实这里有点毛病.谢谢你
