$ketemu=mysql_num_rows($login); 
$r=mysql_fetch_array($login); 
 
// Apabila username dan password ditemukan (valid) 
if ($ketemu > 0){ 
 session_start(); // Untuk memulai session 
 
  // Daftarkan session ke server

Maaf master2, newbiew ne...
Saya coba untuk memasukan timer itu ke dalam sessionnya tapi knpa error ya?

Ne script saya (masih belajar master..^_^ ) :

<?
session_start();
require_once "cekWaktu.php"; //Koneksi dengan fungsi periksa waktu

function anti_injection($data){
$filter = mysql_real_escape_string(stripslashes(strip_tags(htmlspecialchars($data,ENT_QUOTES))));
return $filter;
}
$username = anti_injection($_POST[username]);
$password = anti_injection(md5($_POST[password]));

// pastikan username dan password adalah berupa huruf atau angka.
if (!ctype_alnum($username) OR !ctype_alnum($password)){
?>
<script language="javascript">
document.location="index.php?page=AntiSQLInjection";
</script>
<?
}
else{
$server = "localhost";
$username = "root";
$password = "";
$db_name = "db_joris";
$db = mysql_connect($server,$username,$password) or DIE("Connection
is down ");
mysql_select_db($db_name) or DIE("Database name not available !!");


$login = mysql_query("select * from guru where
(username = '" . $_POST['username'] . "') and
(password = '" . md5($_POST['password']) . "')",$db);
$ketemu = mysql_num_rows($login);
if ($ketemu == 1)
{
$_SESSION['username'] = $_POST['username'];
header("location: securepage.php");
}
else
{
header("Location: index.php?page=Salah");
}

} //Tutup Terakhir
?>

-----------------------------------
Kalo boleh tau taruh dimana ya script buat expire session itu masta?

coba pakai cookie...

//...sebelumnya
$username = anti_injection($_POST[username]);
$password = anti_injection(md5($_POST[password]));
setcookie($_POST[username],$user,time()+60);
//...selanjutnya

satuannya dalam detik, jadi code diatas itu waktu expire nya 1 menit.

Dibawah :
Code:
<?php $username = anti_injection($_POST[username]);
$password = anti_injection(md5($_POST[password])); ?>

nih gw kasih lengkapnya. biar yg masup sini gak bingung bacanya.

ini formnya login.php
Code:
<?php //ini adalah awal file HTML
<html>
<head><title>Login Page …!</title></head>
<body>

<form action=index.php method=POST>
<table
border=0
bcolor=#DFDFDF><tr><td>username</td><td><input
type=text name=username></td></tr>
<tr><td>password</td><td><input type=password name=password></td></tr>
<tr><td></td><td><input type=submit name=submit value=submit></td></tr>
</table>
</form>

</body>
</html>
//ini adalah akhir file HTML ?>


jika ditekan tombolnya, maka akan mengarah kemari
index.php

Code:
<?php require_once “functions.php”;
if (( $_POST['username'] == ‘admin’ ) && ( $_POST['password'] == ‘admin’))
{
$_SESSION['user'] = $_POST['username'];
login_validate();
header(“location: admin.php”);
}

else if ( empty($_POST['username']) && empty($_POST['password']) )
{
header(“location: login.php”);
} ?>


khan di-index.php ada fungsi login_validate() tuh..
nah itu berasal dari sini

Code:
<?php session_start();

function login_validate() {
$timeout = 30;
$_SESSION["expires_by"] = time() + $timeout;
}

function login_check() {
$exp_time = $_SESSION["expires_by"];
if (time() < $exp_time) {
login_validate();
return true;
} else {
unset($_SESSION["expires_by"]);
return false;
}
} ?>


nah ini Admin.php nya
Code:
<?php require_once “functions.php”;

if (ISSET($_SESSION['user']))
{
if (!login_check()) {
header(“Location: logout.php”);
exit(0);
}
else {
echo “Jika tidak ada kegiatan sama sekali, anda akan logout secara otomatis … “;
}
}

else
{
echo “Anda tidak berhak untuk ngapa-ngapain … !! big grin“;
} ?>


untuk sisi sekuritinya, kyk anti injection, strip tags, trim, dll bisa liat di bagian atas...
