?>
<a href="signin.php">please click here to try again</a>
<?php 
}
else
{
while($rows = mysql_fetch_array($r))
{
$level = $rows['level'];
}
if($level = 1)
{

				 $Month = 2592000 + time(); 
 //this adds 30 days to the current time 
 setcookie(admin, $fname, $Month);

				header("location:sys.php");
				  }
				  else
				  {
				  echo "Welcome ".$fname."Sorry , but you are not an admin";
				  }
				  }
				  }

and the sys.php is :

<?php
if(!isset($_COOKIE['admin']) )
{

or 'admin'
i dunno mohammed but may this help
gl

well it might help but i tried it befor and nothing has happened . it just keep saying , please login , please login , please login.
thanks for ur help

well this is not working too , check the code below :

<?php
if(!isset($_REQUEST['username']))
{
?>
<a href="login.php">click here </a>
<?php
}
else
{
include_once "classes/class_lib.php";
$db = new db();
$db->connect();
$db->select();

$username = $_REQUEST['username'];
$pass = $_REQUEST['password'];
$pass = md5($pass);
$r = mysql_query("SELECT * FROM members WHERE username = '$username' AND password = '$pass'");
$n = mysql_num_rows($r);
if($n == 0)
{
echo "wrong username or password<BR> ";
echo "<a href='please click here : <a href='signin.php' title='signin'>sign in </a>";

}
else {
while($rows = mysql_fetch_array($r))
{
$name = $rows['fname'];
$level = $rows['level'];
}
if($level == 2)
{
$f = "user";
}
else if($level == 1)
{
$f = "admin";
}



				  $ex = time()+60*60*2;
                  setcookie($f, $fname, $ex);
				  setcookie("loggedin", $fname, $ex);
				 

				  echo "if you are not redirected within a short time , please click <a href='index.php'> ** here ** </a> ";
				  header("location:index.php");
				  
				  }
				  }

and nothing is happening . and i cant get what is wrong !!

can u chekc plz
that useing $_SESSION can lead to the same Problem?
are cookies enabled via ur browser?

i think the $_REQUEST is holding data within the same script and hence u cant transfer it
to another page better u use $_SESSION to keep track for all ppl logged in

i know that maybe not helpin but i m also new to this tryin to learn.. and tryin
to offer some help if i can..
