Userdata and session data into database

[eluser]someone [/eluser]
I found a problem...
Instead of

Code:

$checklogin = $this->db->select('id_user', 'username')->where(array('username' => $username, 'password' => $password))->get('users');

It should be

Code:

$checklogin = $this->db->select('id_user, username')->where(array('username' => $username, 'password' => $password))->get('users');

Thanks for help anyway! :-)
