I just want to access variables!

[Robby_G]

so, I have a vague understanding of sessions, forms, and how global variables are handled in certain arrays. but between the php manual and html reference docs, I'm very confused about how to use $POST or $GET or $REQUEST.

I hope I explain this correctly: Basically, I simply want to have a few "global" variables that remain in existance while the user goes from one page to another. I know how to do this inside a href command where you see a ? and then the var=assignedvalue. But can I keep a variable going between pages without this way ( I believe that way is related to GET in the HTML form method sense - maybe I'm trying to do this with POST?)

???

You will need to use sessions for that.

It is a bit mucht to explain exactly how & what in general. Please check the manual for sessions.

I read about that too and I'm still confused! This is from the manual:

session_start() creates a session or resumes the current one based on the current session id that's being passed via a request, such as GET, POST, or a cookie.

so, it looks like if I somehow use GET, or POST, a session is implyed and started automatically?

Basically, what you do, is :"

• At each page where you ewant to use variables which were present in the last, but not parsed throughthe url, right after the <? tag , you place seesion_start()
  In the page, you can then register variables (sesion_register(somevariable)
  and you can retrieve variables from previous pages:

$somevar = $HTTP_SESSION_VARS[somevar];

That's in short all. There is a lot more you can do but it is a bit much to explain all here.

As I said.. Check the manual.

Try:

<?
session_start()
$test = "HI the!";
session_register(test);
<a href=nextpage.php>link</a>
?>

Nextpage.php

<?
session_start()
echo $HTTP_SESSION_VARS[test];
?>

thank-you!!!!

I think this will be the seed of information I can grow on! I will read the manual but its always hard to figure out which page to read first!
