You have a logic issue with your code that you need to fix.

In your code, you save the result from your query as $q = $this->db->get('testing'), and $q will always evaluate to true regardless of the number of rows your return.

You need to check the number of rows using $query->num_rows() > 0 and then the rest of you code will behave as you expect.
