Sessions - form fields not updated after using 'Back' button

[jleeman]

I have two pages, A and B. Page A has a form, and its submit button goes to page B (using the GET method, not POST). I register page A's form variables on page B using session_register().

When I fill out the form on page A, and click 'Submit', the values are properly propagated to page B as expected. Now I click on the browser's 'Back' button, and make some changes to the form fields on page A, and click 'Submit' again. This time the form variables are NOT updated on page B.

Anyone know the proper way to do this? I want to stay away from using the session_unregister() function on page A.

Thanks!

perhaps at the top of page B you could flush out the session array:

$_SESSION = array ();

i might suggest you simply include the form on page B (prepopulated with all the user data) so the user doesn't have to hit the back button to make changes. this is pretty standard design logic:
1. fill out a form
2. here's what you entered, if this is not correct, make changes below
