这个是用来前台的页面调用下面的php.

<br /><?php<br />if (!$_POST["upfile"]&&$_FILES["upfile"]["name"]=="")<br />{<br />	echo "no file<p>";<br />	echo "click<a href=\"up_forward.html\">there</a>return!";<br />}<br />else <br />{<br />	$filepath="upload/";<br />	$name=$filepath.$_FILES["upload"]["name"];<br />	while (file_exists($name))<br />	{<br />		$temp=explode(".", $name);<br />		$name=$temp[0]."0".".".$temp[1];<br />	}<br />	if(move_uploaded_file($_FILES["upfile"]["tmp_name"], $name))<br />	{<br />		if ($_POST["owner"])<br />		{<br />			$owner=$_POST["owner"];<br />		}<br />		else <br />		{<br />			$owner="NULL";<br />		}<br />		if ($_POST["describe"])<br />		{<br />			$describe=$_POST["describe"];<br />		}<br />		else<br />		{<br />			$describe="NONE";<br />		}<br />		$time=date("y-m-d H:m:s");<br />		$content=$_FILES["upload"]["name"]."||".$owner."||".$describe."||".$time."\n";<br />		file_put_contents("record.dat", $content.FILE_APPEND);<br />		echo "name:".$_FILES["upfile"]["name"];<br />		echo "<p>";<br />		echo "is upload successfull.<p>";<br />		echo "click<a href=\"up_forward.html\">there</a>return!";<br />	}<br />	else <br />	{<br />		echo "upload error!<p>";<br />		echo "fail!<p>";<br />		echo "click<a href=\"index.php\">there</a>check!";<br />	}<br />}<br />?><br />

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
