It doesn't help to reset any values. The form data is being resent by
the browser itself, just if the user presses the submit button again
with the same data.
What you could do is mabye use a session to see if the particular user
has sent form data before.

Hi,
How do I stop contents of a form from being readded to the database
if the user hits the refresh button on their browser.
I have tried to unset/destroy the variables in several different

Perhaps a session variable that is set once the form is submitted.
Depending on the data you could also look at having a primary key in the
database.
This issue comes over and over again. The trick, as I learned from this
list, is to send a redirect to the browser to a confirmation page, so the
browser remembers the page redirected to and completely ignores the page
that made the redirection so that neither a refresh nor going back to it
confused as to why giving them a null value doesn't work.
Thanks to all.

Beauford,
The unset() function is for session variables, which are remembered by
the server even after the script finished running, that's their
purpose. Your variables are not session variables but normal
variables.
Wrong! Please go
