upload mere end en fil afgangen

Jeg har dette script, og det kan kun uploade en fil afgangen. Jeg vil gerne havde den til at uploade 6 eller 10 filer istedet for en kun.



--Script--
<?

$uploaddir="pics/";
$youremail="min@email.dk";
$thankspage="index.php?site=ok";
$uptymessage="Hej $realname, du har uploadet filen $file_name";
$ownermessage="$realname [ $email ] has uploaded a file named $file_name\n\nCheck the upload directory.";
$emailmessages = "1";



$x = ereg("^[0-9a-z]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]{2,3}$",$email);

if($x==0)

{
echo "<div align=center><font size=1 face=Tahoma>Fejl. <a href=java script:history.back(-1)>Tilbage</a>.</div>";
}
else {


if ($file == "none") {

echo "<div align=center><font size=1 face=Tahoma>Fejl.<a href=java script:history.back(-1)>Tilbage</a>.</div>";
}
else {
//directory to upload to
copy($file, $uploaddir.$file_name);
unlink($file);

//return thank you page
Header("Location: $thankspage");
}
}
if ($emailmessages == "1") {
//mail you to let you know a new uploaded file
mail("$youremail", "Uploaded file", "$ownermessage");
//mail user to thank them
mail("$email", "Uploaded file", "$uptymessage");
exit;
}

?>
