remote login

[Shr3d]

Hi.
i was searching for a remote login,
i found some hacks, but all those hacks don't login on theirselves,
but redirect to member.php.

I'm searching for a hack(or code only) that processes the login on the same remote page.

This is what i currently have now:

<?
	require('global.php'); 
	if ($bbuserinfo[userid]>=1) 
	{
		$id = $bbuserinfo[userid];
		$query = "SELECT username FROM user WHERE userid=$id";
		$result = mysql_query($query);
		$row = mysql_fetch_array($result);
		
		echo $row[username];
	}
	else
	{
?>
<form action="member.php" method="post">
  <input type="hidden" name="s" value="<?=$session[sessionhash]?>">
  <input type="hidden" name="action" value="login">
  Gebruikersnaam: 
  <input type="text" class="bginput" name="username" size="25"><br>
  Wachtwoord: 
  <input type="password" class="bginput" name="password" value="" size="25"><br>
  <input type="submit" class="bginput" value="Login!">
</form>
<?
	}
?>
