another try.. session help

well... since noone helped me last days.. here's another try :o

i have a news script with admin using sessions.. it worked fine until i installed php4.2.0

i tryed to update the script using http_session_vars and stuff.. it registers the vars but they don't pass to other pages.. why ?

anyone knows a good sessions tut or example for php4.2 that works with older versions too ? 🙂

I am having a similar problem with php4.2.0

I am using session_register().

I set up a small application to test it out with 2 pages. Page1.php contains the following code:

<?php

// put the user in the sesssion
if (!session_is_registered('user')) {
session_register('user');
$user = "Johnny";

}

?>

page1.php has a URL link to Page2.php. Page2.php has the following code:

<?php

echo $user;
?>

Now the session_id is posted with URL and the data is saved in the sessiondata. However, I get the following error:

"Notice: Undefined variable: user in D:\SessionTest\page2.php on line 6"

I have tried using the $_SESSION array variable also and I still get the "undefined variable" error.

Any help, pointer, tips or ideas regarding this problem of ours would be most grateful 🙂

tnxs!

I don't play with $_SESSION
I go with what I know to be safe as well as tried and proven.

So for instance, you have $myVar, which you wish to register and reuse...

<?
$GLOBALS['myVar'] = $myVar;
session_register('myVar');
?>

on the next page...

<?
echo $GLOBALS['myVar'];
?>

as simple as that.
Of course, I'd at all times try to insure that 'myVar' was initially set as a global, but this is just a quick how-to.

The premise of this how-to however is that session_regiser() read from the GLOBAL scope and not the script or object level.

here is the code i'm using...

(...)
session_start();
$HTTP_SESSION_VARS["uid"] = $userid;
session_register("uid");
(...)

if in the other page i do something like..
if (isset($HTTP_SESSION_VARS["uid"]) echo "lala";

lala.. will never show.. hehe
.. i've tryed several ways... using session_is_registered... and so on.. none on them worked.. :q

Surely you need to session_start on the second page as well...? I just say this 'cos I haven't seen any mention of it before now.
