MyBB Community Forums

I've been on the forums here as a guest for a bit now and have pieced together a third party registration page (that also registers for WordPress).

The problem I'm having is with the loginkey. The script successfully inserts the uid, username, salted password, salt, and email. However the loginkey keeps showing up as 0.

The created user is able to login however there is an error message:
Warning [2] array_merge() [function.array-merge]: Argument #1 is not an array - Line: 277 - File: inc/class_session.php PHP 5.3.27 (Linux)

[PHP] errorHandler->error
/inc/class_session.php 277 array_merge
/inc/class_session.php 54 session->load_user
/global.php 55 session->init
/index.php 18 require_once

and they are unable to view the board.

I am assuming this is because of the login key (seeing as they all have to do with sessions) but really am learning as I go with this one so feel free to correct me.

    $base10Rand = mt_rand($rangeMin, $rangeMax); //get the random number
    $newRand = base_convert($base10Rand, 10, 36); //convert it

} 


//Name variables from form

} else {

    $password = wp_generate_password( $length=12 ) ;
	$pwgenerated = true;
}

$wp_user_id = username_exists( $username );
$bb_salt = random_str(8);
$bb_password = md5(md5($bb_salt).md5($password));
$bb_loginkey = random_str(50);

    $email = '[email protected]' ;

$user_data = array(
                'ID' => '',
                'user_pass' => $password,
                'user_login' => $username,
                'user_url' => $web,
                'user_email' => $email,
                'first_name' => $fname,
                'last_name' => $lname,
                'role' => get_option('default_role')
            );

//Connect to MyBB Database
$bb_connect = mysql_connect("localhost", "", "") or die(mysql_error()); 
mysql_select_db("", $bb_connect) or die(mysql_error()); 
$bb_query = mysql_query("SELECT * FROM mybb_users") or die(mysql_error());
$bb_uid = mysql_num_rows($bb_query) + 1;

mysql_query("INSERT INTO mybb_users
(uid, username, password, salt, loginkey, email) VALUES('$bb_uid', '$username', '$bb_password', '$bb_salt', '$bb_loginkey', '$email' ) ") 
or die(mysql_error());  

// Insert data into databses
//$user_id = wp_insert_user( $user_data );
//wp_set_password($password, $user_id);
?>

The resulting mybb_users entry looks like this:

4|TestAccount|13a37d4ed6726555abf0c01b2fd6675c|inqgjzjr|0|[email protected]|0|0|0|0|0|1375379616|0|0|all|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|<lastip>|0|<longlastip>|0|1|0|0|0|0|0|0|0|0|0|0|0|1|0

I have notice that after I login (and get the error message) the loginkey is generated but I still get that error message when I try to login again so maybe it is unrelated?

This is also my first php script ever so I'm sure there are some ugly lines for those of you who are better at it then me.
