Darn it., PHP help, please Options

[Mikeplyts]

Alright, so I'm doing some stuff for a new project of mine and this project includes a member login system and all. I have a lot of stuff set up and logging in was fine, but for some strange reason, now that I try to login, the coding sends me to the activation page. The problem is, my account is already activated.

Here's the file that handles the login process, login.php:

CODE

<?php
require ('../includes/functions.php');
url();

// Set parameters
$username = $_POST['username'];
$password = $_POST['password'];
$safe_password = md5($password);
$remember = $_POST['remember'];
$database['server'] = 'localhost';
$database['username'] = 'username';
$database['password'] = 'password';
$database['name'] = 'database';

// Protect against MySQL Injection
$username = stripslashes($username);
$password = stripslashes($password);

// Connect to MySQL Database
mysql_connect($database['server'], $database['username'], $database['password']);
mysql_select_db($database['name']);

// See if user is valid
function valid_user() {
global $username, $password, $safe_password;

if (mysql_num_rows(mysql_query("SELECT ID FROM users WHERE username = '$username' AND password = '$password' AND safe_password = '$safe_password'")) > 0) return true;
}

// Log in the user
if (count($_POST) > 0) {
$grab_id = mysql_query("SELECT ID FROM users WHERE username = '$username' AND password = '$password' AND safe_password = '$safe_password'");
$id = mysql_fetch_row($grab_id);

if (!valid_user()) {
header ('Location: ' . root . '/login?error=invalid');
}

else if (valid_user() && activated()) {
if ($remember) setcookie('hyfb_user', $username, time() + 31556926, '/');
else {
setcookie ('hyfb_user', $username, 0, '/');
setcookie ('hyfb_id', $id[0], 0, '/');
}
header ('Location: ' . root . '/account/dashboard');
}

else {
header ('Location: ' . root . '/account/activate');
}
}

else {
header ('Location: ' . root . '/login?error=invalid');
}
?>

And here's the function to check if a user is activated, activated():

CODE

function activated() {
    $id = $_COOKIE['hyfb_id'];
    $username = $_COOKIE['hyfb_user'];
    $database['server'] = 'localhost';
    $database['username'] = 'username';
    $database['password'] = 'password';
    $database['name'] = 'database';

    $connection = mysql_connect($database['server'], $database['username'], $database['password']);
    mysql_select_db($database['name'], $connection);

    $activation_find = mysql_query("SELECT activation_key FROM users WHERE ID = '$id' AND username = '$username'");
    $activation_key = mysql_fetch_row($activation_find);
    $status_find = mysql_query("SELECT status FROM users WHERE ID = '$id' AND username = '$username'");
    $status = mysql_fetch_row($status_find);

    if ($activation_key[0] == '' && $status[0] == 'verified') return true;

    mysql_close($connection);
}

Okay, so, the weird thing is, if you look in the activated() function where it says:

CODE

if ($activation_key[0] == '' && $status[0] == 'verified') return true;

it's telling me that my account is activated, yet if I go into phpMyAdmin, I see that my "activation_key" field is " " (or empty, as intended) and my "status" field is "verified".

So, I'm wondering if it could be login.php file, specifically around the part where it's setting the cookies and everything.

Help?
