if (!isset($_SESION***91;"admin"***93;))
{
header("location: login.php");
}
echo "Dang nhap thanh cong";
?>
<?php//login.php
session_start();
if (isset($_POST***91;"login"***93;))
{
$username = trim($_POST***91;"username"***93;);
$password = $_POST***91;"password"***93;;
if ($username == "1" && $password == "1")
{
$_SESSION***91;"admin"***93; = true;
header("location: index.php");
}
}
?>
<form method="post">
Username: <input type="text" name="username" /><br />
Pasword: <input type="password" name="password" /><br />
<input type="submit" name="login" />
</form>
//..
if(!isset($_SESSION***91;'admin'***93;)) {
header('location:login.php');
}
//..
