$HTTP_SESSION_VARS is empty!

philippo

I'm working on that already for the last 3 hours and I still cannot figure out what should be the problem...

on my login-page I'm setting the following session variables:

$username = 'test';
$password = 'abc';
session_register("password");
session_register("username");

On all the other pages I'm using session_start() before using those session variables. Everything works fine if I got register_globals = On in my php.ini.

If register_globals is set to Off, then I run the following line to extract the variables of the $HTTP_SESSION_VARS to be able to use $password and $username:

if (!empty($HTTP_SESSION_VARS)) { extract($HTTP_SESSION_VARS); }

This works fine with $HTTP_GET_VARS, $HTTP_POST_VARS, $HTTP_COOKIE_VARS and all the other global arrays, but with $HTTP_SESSION_VARS it won't. HTTP_SESSION_VARS is always empty, no matter what I do!

I'm using PHP4.0.6 currently running on a win32 machine. I didn't try it on my linux box yet, but anyway, I need to get it to work on both.

hope someone can help me out!
Thanks a lot

$HTTP_SESSION_VARS only exists if after you call session_start();
$HTTP_SESSION_VARS contains only those vars that have been registered PREVIOUSLY. it does not contain the vars that you registered for the first time during the same run of the script.

thanks for your fast answer

That's what I'm doing. I call session_start() and then try to get $HTTP_SESSION_VARS, but it's empty
Right. I'm registering the vars on my first page:
session_register("password");
session_register("username");
on the next page (after having called session_start() of course) I'm trying to get $HTTP_SESSION_VARS, but it's still empty

To get from the first page to the second I'm using Header("Location: secondpage.php");
May this cause the problem that $HTTP_SESSION_VARS is not filled?

...looks like I found a solution!!!
I'm not only registering the variables, I also put them manually into the GLOBALS array:

session_register("password");
session_register("username");

$GLOBALS['HTTP_SESSION_VARS']['username'] = $username;
$GLOBALS['HTTP_SESSION_VARS']['password'] = $password;

on the other page, instead of extracting $HTTP_SESSION_VARS:
if (!empty($GLOBALS["HTTP_SESSION_VARS"])) { extract($GLOBALS["HTTP_SESSION_VARS"]); }

No idea why this should work and why it didn't work the simple way. Looks kinda confusing to me!

thanks for your help

besides, it also works with:

$HTTP_SESSION_VARS['username'] = $username;
$HTTP_SESSION_VARS['password'] = $password;

and on the second page:

if (!empty($HTTP_SESSION_VARS)) { extract($HTTP_SESSION_VARS); }

so, we don't even need to register the variables with
session_register("password");
session_register("username");
...

Does this make sense????
