then bila login kat page tulis "Undefined index: logout in C:\myphp\EasyPHP-5.3.9\www\LMS\authentication.php on line 49"

<?php
require_once 'database.php';

session_start();

function signIn()
{

dbConnect();
$result = runQuery($sql);

if (mysql_num_rows($result) != 0)
{
$data = mysql_fetch_assoc($result);
$_SESSION['username'] = stripslashes($data['username']);
$_SESSION['user_type'] = $data['user_type'];

if ($_SESSION['user_type'] == 'student')
{
header('Location: studentpage.php');
}
else if ($_SESSION['user_type'] == 'staff')
{
header('Location: adminpage.php');
}
}
else {
header('Location: login.php?status=SIGN-IN-FAILED');

}
}

function signOut()
{
session_destroy();
header('Location: index2.php');
}

function isSessionValid()
{
if (!isset($_SESSION['user_id']) || empty($_SESSION['user_id'])) {
signOut();
}

return true;
}

if ($_GET['logout'] == 'true') {
signOut();
}
?>

<?php
require_once 'database.php';

session_start();

function signIn()
{
$sql = 'SELECT username, user_type FROM users WHERE username = "'.addslashes($_POST['username']).'" ';
$sql .= 'AND password = "'.addslashes($_POST['password']).'";';
dbConnect();
$result = runQuery($sql);

if (mysql_num_rows($result) != 0)*
{
$data = mysql_fetch_assoc($result);
$_SESSION['username'] = stripslashes($data['username']);
$_SESSION['user_type'] = $data['user_type'];

if ($_SESSION['user_type'] == 'student')*
{
header('Location: studentpage.php');
}
else if ($_SESSION['user_type'] == 'staff')*
{
header('Location: adminpage.php');
}
}
else {
header('Location: login.php?status=SIGN-IN-FAILED');

}
}

function signOut()
{
session_destroy();
header('Location: index2.php');
}

function isSessionValid()
{
if (!isset($_SESSION['user_id']) || empty($_SESSION['user_id'])) {
signOut();
}

return true;
}

if(isset($_POST)){
signIn();
}

if (isset($_GET) && $_GET['logout'] == 'true') {
signOut();
}
?>

Sekali imbas macam ada 2 kesalahan..

Untuk fail html tu

<td><p class="mtop05 mbottom025"><strong><label for="password">Password</label></strong></p><input tabindex="2" class="inputtext" type="password" name="username" id="password" /></td>

username tukar pada password

Untuk fail php tu

if ($_GET['logout'] == 'true') {

tukar pada

if (isset($_GET['logout']) && $_GET['logout'] == 'true') {

login php (solve)
