[SOLVED] Logout Script

twilitegxa · July 14, 2009

I have a log in script that works, but I forgot how to set the logout script. Can someone help me out? Here is the login script I have:

<?php

//Access Tracking Snippet

//set up static variables
$page_title = "login.php";
$user_agent = getenv("HTTP_USER_AGENT");
$date_accessed = date("Y-m-d");

//connect to server and select database
$conn = mysql_connect("localhost", "root", "")
or die(mysql_error());
$db = mysql_select_db("smrpg", $conn) or die(mysql_error());

//create and issue query
$sql = "insert into access_tracker values
('', '$page_title', '$user_agent', '$date_accessed')";
mysql_query($sql,$conn);
?>

<?php
session_start();

$user_area_location = 'account.php'; // Location of the user area
// Connect to MySQL database:
$access = mysql_connect('localhost','root','') or die ('Could not connect to database');
mysql_select_db('smrpg',$access) or die ('Could not select table');
# #
$error = array();
if($_GET['action']) {
switch($_GET['action']) {
case 'logoff':
unset($_SESSION['loggedIn']);
array_push($error, 'You were logged off.');
break;
}
}
if(!$error) {
if(empty($_POST['username'])) { array_push($error, 'You didn\'t supply a username'); }
if(empty($_POST['password'])) { array_push($error, 'You didn\'t supply a password'); }
}
if(!$error){
$result = @mysql_query('SELECT name, email FROM `users` WHERE username = \''.mysql_real_escape_string($_POST['username']).'\' AND password = \''.mysql_real_escape_string(md5($_POST['password'])).'\'');
if($row = @mysql_fetch_array($result)) {
$_SESSION['loggedIn'] = true;
$_SESSION['userName'] = $row['name']; 
$_SESSION['userMail'] = $row['email'];
header('Location: '.$user_area_location);
die('<a href="'.$user_area_location.'">Go to your user account</a>');
}else{
array_push($error, 'The username or password you provided were not correct');
}
}
?>

Nevermind, I figured it out. I added login.php?action=logoff to the script below:

<?php
if ($_SESSION['loggedIn'] == 1) {
?>
<p>Welcome, <?php echo $_SESSION['userName'] ?> (<a href="login.php?action=logoff" title="Log Out">Log Out</a>)</p>
<?php
} else {
?>
<p>Please <a href="login.php">log in</a></p>
<?php } ?>

on my log.php page.
