Some browsers will reset to blank, others will "remember" what you typed last time. It's got nothing to do with PHP and there is precious little you can do about it, except trust that users chose the browser they preferred, and they LIKE it the way it is, whichever way that is. > 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.

It's still browser-dependent, really, but now your browser isn't doing what YOU want for your form-filling-in-experience... There's still nothing you can do about it from PHP, unless you want to make the user who LIKES it that way have a miserable experience, since you force their browser to not behave they way they expect it. > I even modified my code to check for isset($_SESSION) to not call > session_start again, but no joy. You have to call session_start() on every request to have sessions working in that request... I doubt that you want to skip that for any page involved in your FORM processing... Ignore this "problem" for awhile and see if it doesn't go away. (read: you realize it's not really a problem) -- Some people have a "gift" link here. Know what I want?
