Help Needed - How can I make a login...

...Form from another page, that would use the user's database from VBB for authentication?

i.e:
You have a password autherntication on your site, and the users and passwords have to be registered on the board, it must be easy to do this, but I can't
Any help would be appreciated!
Thanks in Advance!

Yes I would love something like this for my site
with an option of letting them in only if they are in a certain group such as admin or super mod...

would this be possible?

I think I know how to do this now, thanks to the hear me chat hack, the hack uses a code like this, on a php stand alone file:

<?
require("global.php");

if ($bbuserid == 0)
{
   eval("echo standarderror(\$bbtitle,\"".gettemplate("error_nopermission")."\");");
   exit;
}

if ($bbusername == "" || (isset($bbusername))==0)
{
  $getusername=$DB_site->query_first("SELECT username FROM user WHERE userid=$bbuserid");
  $username=$getusername[username];
  $bbusername = $username;
}
else
{
   $username = $bbusername;
}

eval("echo standarderror(\$bbtitle,\"".gettemplate("chat_hack")."\");");

?>

something like this would work, of course you'd have to do some editing, but it should be pretty easy, tehn save this as a .php file and there you have a login!

in member.php find:
if ($action=="login") {

above this add
if ($action=="memberlogin") {
eval("\$logincode = \"".gettemplate("logincode")."\";");
eval("echo dovars(\"".gettemplate("memberlogin")."\");");

}

then create a new template called
memberlogin

and paste this code in it
{htmldoctype}
<HTML>
<HEAD><TITLE>$bbtitle - powered by vBulletin</title>
$cssinclude
</head>
<body>
$header
<center>

$logincode

<br><br>
</center>
$footer
</body>
</html>

then create a link to it

I think that was all I did
here is my link http://www.clubbers.ws/vb/member.php?action=memberlogin

back up your member.php file before trying this.
