here is the code for the login page.

Code: <?php
include("connect1.php");

$p = $_POST['password'];
$logoff = $_GET['logoff'];
$hack = $_GET['hack'];






if($logoff){


unset($_SESSION['userid']);



$message = "You have been logged off";




}


if($hack){

$message = "Naughty Naughty! "; // COOL

}


// escape username and password for use in SQL//person said on board "looks fine" like this
//to prevent sql injections
$u = mysql_real_escape_string($u);
$p = mysql_real_escape_string($p);


// if fields username and password have contents, then...
if(isset($u) && isset($p) && !empty($u) && !empty($p)){ ///changed from if ($u && $p)

$query = mysql_query("SELECT * FROM table2 WHERE username = '$u' AND password = '$p'");

$result = mysql_fetch_array($query);


if($result['username']){ // if username is set, go on...username is a key for $result, and a field in the table.

$message = "You have been logged in";


$_SESSION['userid'] = $result['username'];

header("Location:old.mainsite.php"); // this will redirect them to the application.php page. and exit the script here.
exit;

//IP BANNING CODE START HERE
$s=$_SERVER["REMOTE_ADDR"];

while($ipbancheck3=mysql_fetch_array($ipbancheck2))
{
$IPBANNED=$ipbancheck3[IP];
}
//above lines check to see if user Ip is in banned IPs
