gatting value out of form

[zoya23]

I am just wondering, how can I get the value that has been selected by a customer 2 pages ago in PHP and then use it again later.

For example,
I have a page with list box called "username". This page is called admin.php.

Then, this admin.php page is being processed and the next page is admin1.php. ( i can the value of username without problem).

Then, I have another page called admin2.php which need the value of username in admin.php. How can I get this username value again?

Can anyone please help me?

Thanks

zoya23,

some common approaches:

a) sessions:
http://www.php.net/manual/en/ref.session.php

b) cookies - may be worth considering if you can garantee all users have cookies enabled, and it is only that one value you need to store. otherwise, sessions would probably be more convenient)

c) passing values as hidden input from page to page - there may be good reason to do that in some special scenarios, but if you'd like to have the value available more or less on every page, like sessions or cookies allow, I don't think this is what you are looking for.
