If you already go into storing stuff in SESSION, I suggest another approach: in your form set a hidden tag with a random number as a value (or you can use UNIX timestamp also). Now each time you get a form submit you check: 1) if the timestamp you got from POST isn't in the SESSION or it's different form the one in SESSION then it's the first or new POST and you store data into DB. NB! And you now store this timestamp in SESSION. 2) if the timestamp matches the one already in SESSION you know it's a repost and you discard it.
