POST/GET conflict with sessions

[prouski]

I'm using sessions across several pages, the first one being a form which passes data. The second page caters for the fact that you cannot update session variables with post/get and then presents various links to (for instance) page 3. When clicked, page 3 is displayed.

When the form on page 1 uses 'get' everything works fine, but when it uses 'post' (preferable), I get the dreaded 'Warning: page has expired message' when going back from page 3 to page 2. session_start() is on each page.

Does any one have any smart ideas? Is this a known issue?

Thanks.

When you go back to a page you have already been on, and you posted data to that page, you will have to repost that data when you go back. The browser is saying "page expired" because it isn't allowing the data to be posted again. If you must use this method of jumping back to previous pages, you'll have to use GET variables instead of POST.
