Make sure the page reload doesn't affect stuff

[mdowling]

On my website I'm making I have a lot of stuff that happens when you load a page. Information is sent using the url string. If a user were to refresh the page on a page where I gave his account a special bonus, he would receive the bonus again and again. How can I counter this? Is there something that $_SESSIONs can help me with?

Is there a way I can change the extra PHP information in the url string and the form POSTED data to not be there if the user reloads the same page?

Well, you can set a session variable like form_name_processed, and set it to true once the form is processed.
