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 />

Copy after login

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
