Re: Sessions Lose Form Field Data When Back Button Used?

I have an old PHP page without sessions. When the user submits the form, and then clicks the browser back button, the prior form data is retained. If I now have that PHP page require another page that uses session_start, when the user submits the form, and then clicks the browser back button, the prior form data is lost.

That has to be your code re-setting the session variables or something. PHP won't do this automatically for you.

I even modified my code to check for isset($_SESSION) to not call session_start again, but no joy.

$_SESSION doesn't exist until AFTER you call session_start ;) -- Postgresql & php tutorials http://www.designmagick.com/
