- PHP code
<?phpif (!$_POST["upfile"]&&$_FILES["upfile"]["name"]==""){ echo "no file<p>"; echo "click<a href=\"up_forward.html\">there</a>return!";}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 "<p>"; echo "is upload successfull.<p>"; echo "click<a href=\"up_forward.html\">there</a>return!"; } else { echo "upload error!<p>"; echo "fail!<p>"; echo "click<a href=\"index.php\">there</a>check!"; }}?>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
