</head>

<body bgcolor="#FFFFFF" text="#000000" leftmargin="0" topmargin="0">

<?

require './global.php';

$updir="uploaddir";

$form?$form=$form:$form="form1";

if(!$inputname)$inputname=$_GET['inputname'];

if($uploadfile){

$copyfilename=date('YmdHis',time());

if(!is_dir($updir))mkdir($updir,777);

$filetype=array(".php",".php3");

$type=substr($uploadfile['name'],strrpos($uploadfile['name'],'.'),strlen($uploadfile['name'])-strrpos($uploadfile['name'],'.'));

if(in_array($type,$filetype)){echo "上传的文件不符合格式<a href="javascript教程:history.go(-1)"> 点击返回</a>";exit;}
$dir="$updir/$copyfilename.$type";

if(function_exists("ImageJpeg")&&eregi("(.jpg)$",$uploadfile_name)&&$w)

include("gd.php");

if(move_uploaded_file($uploadfile,$dir)){

chmod($dir, 0777);

$ckupload=2;

}

if(!$ckupload){

if(move_uploaded_file($uploadfile['tmp_name'],$dir)){
chmod($dir, 0777);

$ckupload=2;

}

}

if(!$ckupload){

echo "<CENTER>文件上传不成功,请再次上传，如果多次不成功，请联系管理员<a href="javascript：history.go(-1)"> 点击返回</a></CENTER>";

exit;

}

else {

echo "上传成功1,<A HREF=?>继续上传</A>";

echo"<script>parent.$form.$inputname.value='$updir/$copyfilename$type'</script>";

exit;

}

}

?>

<form name="form1" method="post" action="" enctype="multipart/form-data">

<input class=mmcinb type="file" name="uploadfile" style="height:20px; background-color:#f3f3f3; border:1 solid black;" onMouseOver ="this.style.backgroundColor='#FFC864'" onMouseOut ="this.style.backgroundColor='#f3f3f3'" >
