session problem

scorpioy

I use session to register a variable via a user browses my website. There is a button that open another page when clicked (with target=\"other\"). In this new page (the second page), I have a link that opens another page (the third page) again when clicked (with target=\"other2\"). I want users to browse pages when session variable are registered only.

The problem is that this third page shows that the session variable is not set, or session is not passed to the third page. If I change from target=\"other2\" to target=\"other\" in the second page, there is no such problem, but go to that link without open a new browser. I want that link to be clicked and open page from a new browser while session remains.

How could I solve this problem? Thanks.

Are you using

session_start() on all files, that require sessions? Its a bit hard to tell without some source code you are using.

Yes, I'm using session_start(); and if(session_is_registered('$var')) to check if 'var' is registered.

So how to solve this problem? Thanks.

What other ways can be used for registering session?

unless your using an old version of php, dont use any of the session_register functions or that stuff. you can look in the manual at each function and it will tell you if its deprecated or not.

heres a sample how to do it w/ recent php versions, its very easy

<?php

session_start();

// to set a session var
$_SESSION['test'] = 'im a test';


// to check if a session var is set

if (isset($_SESSION['test'])) {
    // do something
}

I'm using PHP 4.3.3. Do you mean just change from using session_is_registered to isset? It seems still not working.
