I See you're using
PHP:
$username = $_POST['username'];
$password = $_POST['password'];
if(isset($_POST['submit']))
{

Use This instead, As the above gives errors.
PHP:
if(isset($_POST['submit'])) {
  $username = mysql_real_escape_string($_POST['username']);
  $password = $_POST['password'];

database structure link is not working
It's not even that hard...

Code:
CREATE TABLE IF NOT EXISTS `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(80) NOT NULL,
  `email` varchar(100) NOT NULL,
  `password` varchar(80) NOT NULL,
  `fullname` varchar(60) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=29 ;

Sorry for the outdates, this script is really old. I am going to update it in a bit.

You should really use:
PHP:
htmlentities()
When getting things from database base:
PHP:
echo htmlentities($_SESSION['user']);
Because if you don't you will get people trying to SQL inject, they could create a username: Hi<script>alert('Hi');</script>
If you don't htmlentities() then you would get javascript alerts.

A $_SESSION hasn't anything to do with SQL...

I know, look through me.php code:
PHP:
echo "<a href='me.php'>".$_SESSION['user'] ."</a> |";
echos username....
Yes... the username in the SESSION. If I make this code:
PHP:
$_SESSION['user'] = 'Holmes'
the code you gave would have echod Holmes. So your argument is quite invalid, sir.

Yes but i'm saying if your username wasn't Holmes and was Homes<script> then that's where htmlentities() come in!

Well, actually thats where strip_tags and mysql_real_escape_string come in. So please don't start to judge a code if you don't have your facts straight. (Alam) is a great coder, and he wouldn't release an un-safe script.

nothing is working guys.... and changing the login/index page to that just gives me the errors


Notice: Undefined index: username in C:\xampp\htdocs\login.php on line 6

Notice: Undefined index: password in C:\xampp\htdocs\login.php on line 7

Notice: Undefined index: user in C:\xampp\htdocs\login.php on line 50

It's not that hard to fix this. Simply install xampp 1.7.4 and then there you go :)
