i follow the register and login tutorial. Now i am testing the register site and everything works except that the username is not appear in the database. I can't find out why. The valid_credentials and the login.php page seems to be alright.
Here is the code;
user.inc.php
<?php
//bestaat de gebruikersnaam in de database
function user_exists($user){
$user = mysql_real_escape_string($user);
$total = mysql_query("SELECT COUNT('user_id') FROM `user_system` WHERE `user_name` = '{$user}'");
return (mysql_result($total, 0) == '1') ? true : false;
}
//is de gebruikersnaam en paswoord combinatie correct
function valid_credentials($user, $pass){
$user = mysql_real_escape_string($user);
$pass = mysql_real_escape_string($pass);
$total = mysql_query("SELECT COUNT('user_id') FROM `user_system` WHERE `user_name` = '{$user}' AND `user_password` = '{$pass}'");
return (mysql_result($total, 0) == '1') ? true : false;
}
function is_active($user){
$user = mysql_real_escpe_string($user);
$sql = "SELECT
COUNT(`user_activations`. `user_id`)
FROM `users`
INNER JOIN `user_activations`
ON `users`, `user_id` = `user_activations`,`user_id`
WHERE `users`,`user_name` = '{$user}'";
$result = mysql_query($sql);
return (mysql_result($result, 0) == '0') ? true : false;
}
function activate_account($aid){
$aid = mysql_real_escape_string($aid);
mysql_query("DELETE FROM `user_activations` WHERE `activations_code` = '{$aid}'");
}
//paswoord vergeten
function random_string($length){
$charset = array_flip(array_merge(range('a', 'z'), range('A', 'Z'), range(0, 9)));
shuffle($charset);
$password = array_slice($charset, 0, $length);
return implode('', $password);
}
//voegt een gebruiker toe aan de database
function add_user($user, $email, $pass){
$user = mysql_real_escape_string(htmlentities($user));
$email = mysql_real_escape_string($email);
$pass = sha1($pass);
$charset = array_flip(array_merge(range('a', 'z'), range('A', 'Z'), range(0, 9)));
$aid = implode('', array_rand($charset, 10));
$body = <<<EMAIL
Hallo,
dank voor het registreren, voordat je gaat inloggen is het nodig dat je je account gaat activeren.
omdat de doen kan je gewoon op deze link klikken, http://www.robcnossen.nl/activate.php?aid={$aid}
EMAIL;
mail($email, 'je nieuwe account in robbcnossen.nl', $body, 'From: robcnossen@quicknet.nl');
mysql_query("INSERT INTO `user_system` (`user_name`, `user_password`, `user_email`) VALUES ('{$user}', '{$pass}', '{$email}')");
$user_id = mysql_insert_id();
mysql_query("INSERT INTO `user_activations` (`user_id`, `activations_code`) VALUES ({$user_id}, '{$aid}')");
}

login.php
<?php
include('init.inc.php');
$errors = array();
if (isset($_POST['username'], $_POST['password'])){
if (empty($_POST['username'])){
$errors[] = 'De gebruikersnaam mag niet leeg wezen.';
}
if (empty($_POST['password'])){
$errors[] = 'Het paswoord mag niet leeg zijn.';
}
if (valid_credentials($_POST['username'], sha1($_POST['password'])) === false){
$errors[] = 'Gebruikersnaam/paswoord zijn niet goed ingevuld.';
}
if (empty($errors) &&is_active($_POST['username']) === false){
$errors[] = 'Deze account is niet geactiveerd.';
}
if (empty($errors)){
if(isset($_POST['set_cookie']) && $_POST['set_cookie'] == '1'){
setcookie('username', $_POST['username'], time() + 684800);
