waiting for jacek to look at code

It all looks very fine and neat except for this little bit

function fetch_current_user_id($username){
$username = mysql_real_escape_string($username);
$sql = 'SELECT `user_id` FROM `users` WHERE `user_name` = '{$username}'';
 
$result = mysql_query($sql);
 
return mysql_result($result, 0);
 
}
 
if(empty($_SESSION['uid'])) {
$_SESSION['uid'] = fetch_current_user_id($_SESSION['username']);
 
}

So lets neaten that up

function fetch_current_user_id($username){
	$username = mysql_real_escape_string($username);
	
	$sql = 'SELECT `user_id` FROM `users` WHERE `user_name` = '{$username}'';
	$result = mysql_query($sql);
	
	return mysql_result($result, 0);
}

if(empty($_SESSION['uid'])){
	$_SESSION['uid'] = fetch_current_user_id($_SESSION['username']); 
}

Now, you should can calling the function in the init file (not in the function definition file) once you have stored the username in the session.

There is also a fairly obvious syntax error on this line, which you should be able to spot

$sql = 'SELECT `user_id` FROM `users` WHERE `user_name` = '{$username}'';

Can it be this?

$sql = 'SELECT `user_name` FROM `users` WHERE `user_id` = '{$username}'';

No, you want to query the username, I'll just tell you It should be this

    $sql = "SELECT `user_id` FROM `users` WHERE `user_name` = '{$username}'";
