Hi guys,

im using this script i've come across which is working nicely. However there is something that im trying to add.

The login script is this...

<html>
<head>
<title>Login</title>
</head>
<body>

<div align="center"> <br>
  <strong><font color="#999999" size="7" face="Courier New, Courier, mono">A D 
  M I N I S T R A T I O N</font></strong><br>
  <br>
  <br>
  <font color="#FF8000" face="Arial, Helvetica, sans-serif"><strong>This Is A 
  Restricted Area. Please Login ...</strong></font> <br>
  <br>
  <form method="post" action="<? echo ($PHP_SELF); ?>">
    <table border=0 cols=2 width=200 cellpadding=3 cellspacing=3>
      <tr> 
        <td width=100><font color="#000080" size="2" face="Arial, Helvetica, sans-serif"> 
          User ID: </font></td>
        <td width=100> <input type="text" name="uid" size="8"> </td>
      </tr>
      <tr> 
        <td width=100><font color="#000080" size="2" face="Arial, Helvetica, sans-serif"> 
          Password: </font></td>
        <td width=100> <input type="password" name="pwd" SIZE="8"> </td>
      </tr>
     
    </table>
    <br>
    <input type="submit" name="submitlogin" value="Login">
  </form>
</div>

</body>
</htML>

which obviously redirects to the index page which has the following include file <?php include ("access_control.php"); ?>

This include file contains...

<?
include ("config.php");
include ("errors.php");
include ("common.php");
include ("connect.php");


while (list($var, $val) = each ($_REQUEST))
{
IF ($var == "cookieid" AND !isset($_COOKIE[cookieid]))
{
echo ("You can not pass login parameters via GET operations.");
exit();
}
}

reset($_REQUEST);





IF (isset($_REQUEST[uid]) AND !isset($_COOKIE[cookieid]))
{
$grabuser = "SELECT recID FROM user WHERE username = '$_REQUEST[uid]' AND password = '$_REQUEST[pwd]'";
$result = @mysql_query($grabuser);
sql_query($result, "$errors[03]");

IF (@mysql_num_rows($result) == 0)
{
error ("$errors[04]");
include ("login_form.php");
exit();
}

ELSE
{
$userid = @mysql_result($result,0,"recID");
$processing_login = true;

$cookie_setter = @setcookie ("cookieid", $userid, time()+$maxlifetime);

IF (!$cookie_setter)
{
error ("$errors[05]");
}

ELSE
{
?>
<META HTTP-EQUIV=Refresh CONTENT="2; URL=index.php">
<font color="#000080" size="2" face="Arial, Helvetica, sans-serif">Please hold one second while we process 
your login...<br>
If this page does not refresh in 3 seconds, <A HREF="index.php">click here</a>. 
<?
exit();
}

}

}


ELSE IF (!isset($_REQUEST[uid]) AND !isset($_COOKIE[cookieid]))
{
include ("login_form.php");
exit();
}



IF ($_REQUEST[action] == "logout")
{
$cookie_setter = @setcookie ("cookieid", $userid, time()-$maxlifetime);

IF (!$cookie_setter)
{
error ("$errors[05]");
}

ELSE
{
?>
</font>
<META HTTP-EQUIV=Refresh CONTENT="2; URL=index.php">
<font color="#000080" size="2" face="Arial, Helvetica, sans-serif"> Please hold one second while we log 
you out...<br>
If this page does not refresh in 3 seconds, <A HREF="index.php">click here</a>. 
</font><BR>
<BR><BR><BR>
<?
exit();
}

}

?>

Basically what im trying to do is parse the username value though to the index page, so i can say hello user: $username etc etc.

However i can't work out what code to put in on the index page.

Can someone help, it would be appreciated.

Thanks.
