If you are worried about the form data being reposted (even if it's the same) this would not prevent them from hitting their reload button and resubmitting the form data. The way to avoid this is to include a hidden field that contains a random value which is generated when the form screen is created in PHP. The script that processes the form data should check whatever database you stored your form data into to ensure that that random value has not yet been stored. If so, don't save the data a second time.

Hello I need to find a way to prevent a user from hitting 'back' on their browser and reposting the form data. Thanks Dusten
