Ajax Framework (CJAX) for Codeigniter 2.x+

[eluser]fran-quero[/eluser]
Thank you for the select info, I'll check it out. I have to go deeper in the documentation.

Just made my review in Sourforge!

Now I have new question. With this code I show a modal if an identification id exists in a database table:

Code:

$ajax->Exec('id', $ajax->overlay(base_url().'ajax/newuser/checkid/|id|'), 'blur');

It works, but I'd like it to JUST show the modal if the id is found. When an id is not found cAjax shows an empty modal. Is that possible?
