Is session->userdata supposed to return an array?

See the user guide.

$query->result() returns an array of objects, one for each record in the resultset. You should be doing something like

Code:

$query = $this->db->query("SELECT id FROM users WHERE user = 'asd'");

if ($query->num_rows() > 0)
{
    $row = $query->row();
    $id = $row->id;
}
else
{
    $id = FALSE;
}
