here is my code,u only have to care for the session part:
this is the login page:
<?php
session_start();
$adminname = "emad";
$serverpassword = "omda";
$servername = "localhost";
$dbname = "mall";
$sql = "SELECT * FROM registration WHERE username = '$username' and
password='$password'";
if($username != ""):
$conn = mysql_connect($servername, $adminname, $serverpassword);
mysql_select_db($dbname, $conn);
$result = mysql_query($sql, $conn);
if(@mysql_num_rows($result) != 0)
{
$row = mysql_fetch_array($result);
$valusername = $username;
session_register("valusername");
mysql_close($conn);
header("location:http://$HTTP_HOST/mall/menu.php");
exit();
}
else
{
echo "<h2>Sorry,you entered either a wrong User Name or Password.</h2>Try
again<BR>";
echo "<a href='login.php'>Back</a>";
}
else:
?>
<html>
<head>
<title>Login Page</title>
</head>
<body background="o3b.gif" onLoad="document.myForm.username.focus();">
<FONT color="#fdf8db">
<table>
<form name="myForm" method="post" action="login.php">
<tr><td align="right"><FONT color="#fdf8db"><b>User
Name</b><td><input type="text" name="username"
size="40">
<tr><td align="right"><FONT
color="#fdf8db"><b>Password</b><td><input
type="password" name="password" size="40">
<tr><td colspan="2" align="center"><input type="Submit"
value="Login">
</form>
<tr><td><a href="forgetpass.php"><FONT size="-1">Forgot

</table>
</body>
</html>
<?php
endif;
?>

session_start();
if(!(session_is_registered("valusername")))
{

exit();
}
?>
