Login using Cookies

Copy and paste the following code into your body tags and run it (code comments are included).
If you want to see the live result, try it here (new window).
This script set a cookie to save the user information sent by an online form. The online form is displayed only if the cookies has been saved.

The online form:
<? /*First we check if a cookie has been set*/ if(isset($_COOKIE['login']) && isset($_COOKIE['pass'])) { echo 'Welcome again '.$_COOKIE['login'].'<p>Come back in 10 minutes to change your login information.</p>'; } else { /*display a login form in order to set the cookies*/ ?> <!-- the online form - you can replace the method from get to post, it's up to you --> <form method="get" action="setcookies1.php"> <p>Login name: <input type="text" name="login" /></p> <p>Password: <input type="password" name="pass" /></p> <input type="submit" /> </form> <? } ?>

Implement the setcookie function:
<? /*Common stripping to avoid any type of hack*/ $_GET['login']=trim(strip_tags($_GET['login'])); $_GET['pass']=trim(strip_tags($_GET['pass'])); if(strlen($_GET['login']) > 0 && strlen($_GET['pass']) > 0) { /*Set the cookies named login and pass - you can also encrypt the password for more safety - we set a time for the cookie expiration in 10 minutes */ setcookie('login',$_GET['login'],time()+60*10); setcookie('pass',$_GET['pass'],time()+60*10); } else { echo 'Please enter something, go back to where you were previously.'; } ?>
