Passing data through multiple web pages

[ben]

Hi guyz,
I am developing a website using php.This website involves
dealing with forms which span over multiple pages.

I want data obtained from 1 form to be available after 3-4 pages.

This can be ofcourse achieved through use of cookies.But i am keeping
cookies as last option as they r not supposed to be reliable.I want to
achieve the above task using SESSION VARIABLES.Can someone please guide
me how to use session variables?(and pass form data across several
pages using them?)

Thanking in advance,
bye,
ben

Hi,

Try php.net for starters:
http://nl3.php.net/manual/en/ref.session.php

Generally speaking:
1) Make sure session work on your machine.
(eg: where are session stored? CHeck also php.ini for session.autostart to
make your life easier. If you have no write-access to php.ini, use
session_start() above every page)
2) on page1.php: put something in a session
eg
$_SESSION["firstname"] = $_POST["firstname"];

3) On page23.php, retrieve it:
echo $_SESSION["firstname"];

Good luck and be sure you read the manual at php.net. It is good and
explains a lot more than I possibly could over here.

That's what hidden fields are for. Session variables aren't very good
solution here, as the user would get strange behavior if multiple
windows are opened, or if the back button is used.

THAT depends on the quality of the underlying code Chung. :-)
But of course: Passing them all through hiddwen fields is another
possibility. I use it quite often actually. :-)
