I have created one user\_form class that extends zend form, it has 4 elements username, password, hash for csrf and at last submit button.

Creating object of user\_form renders all those four element.

After validating login in controller action i checks fail attempts, and after some fix number of fail attempts I want to add zend captch before submit button.

I added captcha element and it was appended at after submit button.

How can I add zend element at specific position? Or How can i add it before submit button?

Also let me know that the way am I doing is proper?
Waiting for your reply.
Thank you...
