firefox resubmits data on page refresh

[calmchess]

How do I stop firefox from reposting post data when my php page is refreshed?

Don't know if you can, but what I usually do when you insert data using POST, is to redirect using header().

 

That way, you can't refresh on that page as it redirects after the script is complete and if you click back, you're taken to the page where the form is.

 

I find that's the easiest way around it.

Sessions.

create session on submit, if session is greater than one, exit;
