Yes, *If the user hits refresh after submitting the form they will
refresh **
*nextpage.php. Which is going to resubmit the data to mysql? (duplicate
entry)**
No, you didn't read what I wrote.
The form submits to formhandler.php which submits the data to MySQL and
then redirects to nextpage.php. Nextpage.php *does not* submit any data
to MySQL. Read my post again, carefully this time.
And please include the list when replying.

Disabling client-side features like refresh and back is not the right
way to solve this problem. The most common solution is to redirect the
user to the next page from the form handler rather than outputting the
next page from the form handler.
For example...
form.php shows the form, which submits to formhandler.php which
processes the form and then does a header('Location: ...') redirect to
nextpage.php.
If the user hits refresh after submitting the form they will refresh
nextpage.php. If they hit back they will be taken back to form.php.
