I know that dragging and dropping the captcha component into your form component it is real easy to use the front end and back-end validation. We are using custom forms though and trying to get the captcha component to validate through back-end process with the client has been a bit difficult.
Has this been done? If so, can you supply an example?
I have validated the captcha challenge field against an empty field but I am having difficulty finding how to access on the back-end validation using jquery on the client without the form wrappers.
