Problem pulling data from database..

[saamde]

Hello, i'v been following a tut on how to make a register and login system and iv hit a brick wall... It won't display data..

 

This is my users.php

<?php
function user_data($user_id) {
	$data = array();
	$user_id = (int)$user_id;
	
	$func_num_args = func_num_args();
	$func_get_args = func_get_args();
	
	if ($func_num_args > 1) {
		unset($func_get_args[0]);

			$fields = '`' . implode('`, `', $func_get_args) . '`';
			$data = mysql_fetch_assoc(mysql_query("SELECT $fields FROM `users` WHERE `user_id` = $user_id"));
			return $data;
	}
}

function logged_in() {
	return (isset($_SESSION['user_id'])) ? true : false;
}

function user_exists($username) {
$username = sanitize ($username);
(mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username'"), 0) == 1) ? true : false;
}

function user_active($username) {
$username = sanitize ($username);
return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND `active` = 1"), 0) == 1) ? true : false;
}

function user_id_from_username($username) {
$username = sanitize($username);
return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '$username'"), 0, 'user_id');
}

function login($username, $password) {
$user_id = user_id_from_username($username);

$username = sanitize($username);
$password = md5($password);

return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND `password` = '$password'"), 0) ==1) ? '$user_id' : false;
}
?>

and iv used this(see code) to get the user first name,

Hello, <?php echo $user_data['first_name']; ?>!

buts its showing like this...(see image)

 

 

 

Help anyone?

 

 

Thanks, Sam

 

If you need to see some other code files, let me know and ill post.

And what's the code that sets $user_data?

 

 

Also, user_data() won't return anything if you don't pass it the fields you want returned. If a function returns a value then it should always return a value. Maybe you can assume a default of getting all the fields?
