Ideal way for user information storing in cms and working with it

Yeah.

I had to do this several times.

I simply created a model which looked a little like this.

Code:

class User extends CI_Model {

function id_to_name($id) {
$query = $this->db->get_where('user_table', array('id' => $id));
$q = $query->row();
return $q->username;
}

}

Now all you have to do is call it in your controller.

Code:

$username = $this->user->id_to_user($this->session->userdata('id'));

That's a bland example, you can do whatever checks you want to ensure the user id exists, but it won't be necessary if your authentication is setup right.
