adding captcha with preexisting form

i have pretty much given up on getting an answer to my question originally, because of all the errors it was generating, so i am using a standard solution to add a captcha, but now the question is how to make sure that if the security question is not answered properly how can the form retain its contents-answers from the user, so that they get a second chance at the security question. if the form has validation using webassist client side validation there is the javascript in the form submission, but the captcha code is usually php. in a die statement there the php code might print something and a back button unfortunately clears the contents of the form. so where in the form action properties can we tie together the javascript and the php code so they work together?
examples anyone? especially pertaining to webassist builder+ validation+captcha code.
thanks in advance

You would need to use server validation to be able to retain the information.

To add server validation, go to insert -> Web Assist -> CSS Form Builder -> Server Validation.

then select each form item, and in the properties inspector click the lightning bolt next to Initial value and select the corresponding item from the validated entries collection.


This is not going to work with third party captcha however.

One way to work around this, is to create a blank page, and add the secure login form to the page.


you can then copy over the code for creating the captcha element, as well as the server validation server behavior, then add server validations for the rest of the form elements on the page.
