一个关于文件上传的页面.遇到错误.求大神指导指导

	
upload your file


	


	




	




	

	

这个是用来前台的页面调用下面的php.

if (!$_POST["upfile"]&&$_FILES["upfile"]["name"]=="")

{

	echo "no file
";

	echo "clicktherereturn!";

}

else 

{

	$filepath="upload/";

	$name=$filepath.$_FILES["upload"]["name"];

	while (file_exists($name))

	{

		$temp=explode(".", $name);

		$name=$temp[0]."0".".".$temp[1];

	}

	if(move_uploaded_file($_FILES["upfile"]["tmp_name"], $name))

	{

		if ($_POST["owner"])

		{

			$owner=$_POST["owner"];

		}

		else 

		{

			$owner="NULL";

		}

		if ($_POST["describe"])

		{

			$describe=$_POST["describe"];

		}

		else

		{

			$describe="NONE";

		}

		$time=date("y-m-d H:m:s");

		$content=$_FILES["upload"]["name"]."||".$owner."||".$describe."||".$time."\n";

		file_put_contents("record.dat", $content.FILE_APPEND);

		echo "name:".$_FILES["upfile"]["name"];

		echo "
";

		echo "is upload successfull.
";

		echo "clicktherereturn!";

	}

	else 

	{

		echo "upload error!
";

		echo "fail!
";

		echo "clicktherecheck!";

	}

}

?>

问题就在于上传之后,提示文件上传成功,但是upload文件夹里面文件名是0的倍数,而且没有文件格式..这个是怎么回事呢?


提示的错误就是下面这些..
Notice: Undefined index: upfile in D:\phpnow\htdocs\b\up_back.php on line 2

Notice: Undefined index: upload in D:\phpnow\htdocs\b\up_back.php on line 10

Notice: Undefined offset: 1 in D:\phpnow\htdocs\b\up_back.php on line 14
