I'll try to put this in the simplest terms I can.
I've created a php page that (when it's loaded in the browser) updates a MySQL db.
That part functions just fine.
The trouble is every time that page is refreshed by the visitor it updates the db with additional data. Every time!
So, is there a way to ensure it only updates the db once per session?
Or maybe prevent the page from being refreshed or reloaded by the visitor?
