After someone submits my form, if they hit the "back" button on the browser, it returns to the form with all of the data still in the fields. Is there a way to force the data to clear so that someone cannot go back and simply resubmit the same data? I have installed a captcha but someone can still go back and only have to re-enter the captcha to re-submit. I would like to be able to clear the form data so going back on the browser will show a blank form. Thanks!

Clear form data after submission

This will not do exactly what you asked, but it may do functionally what you want: Set "No Duplicates" for a field such as username or a hidden field with client ip. Then if someone clicks back on their browser and attempts to resubmit, they will get an error and the form will not resubmit. You can even write a custom validation error message telling them they have already submitted.

MemberI'm having a similar issue with a contest form. I set the email field to be no-duplicates and added recaptcha to the form. But I have some "Prize Pig" who wrote a script that goes back and resubmits the form with a random email alias. I'd love to also limit by IP address but there isn't an option for NO DUPLICATES for a hidden field. Or am I missing something?
Thanks
