[wp-hackers] Frontend form

[Eric Mann]

We'd have to see what code you're using in the form to diagnose the "Headers
already sent" issue, but typically this is due to either `echo`ing content
too early in WP's execution or trying to modify the page headers too late in
WP's execution.

My guess is that you're trying to use some kind of HTTP redirect within the
content of the page ...

As for preventing the browser's back button ... don't.  It's bad form to
modify the behavior of the browser like that, and the user might have a
legitimate reason to use the back button.  Instead, just validate the form
to prevent duplicate submissions - i.e. use a nonce to detect whether or not
this is a repeat submission and reject the re-submission.
