Having some session issues, and could use a quick hand

function set_userdata() expects either a string or an array.
But function update() can return FALSE which is then passed to set_userdata():

Code:

return ($query->num_rows() > 0) ? $query->row_array() : FALSE;

Why do you query the database at all?
You could use:

Code:

(...)
        $this->db->where('id', $form['id']);
        $this->db->update('users', $form);

        return $form;
    }
