pass on variables from joomla to VM2

[fabvincent]

Hi all,
I implemented a tiny code on the default.php page of my category so I can have a breadcrumb. Everything's ok but I need to pass on a session variable form my index page (joomla 2.5) to the default page (Virtuemart 2).
I've been using a simple $_SESSION in between the two of them but they don't seem to connect. so my variable from joomla stays blank on the default.php page. I know the problem has been addressed before and quite a long time ago (found a 2007 subject). Is there any way to pass on the variables? Should I use a $_GLOBAL?
Thanks in advance.

does this not work?

$session = JFactory::getSession();
$myvar = $session->get('myvar');

Ehrm strange, breadcrumbs are native there.

What? You cannot pass a session variable between two pages on the same server. they HAVE THE SAME SESSION!

I've been using a simple $_SESSION

If you are in joomla, you maybe should use the stuff which joomla gives you. Else you can destroy your session, which makes your joomla installation unusable.

in between the two of them but they don't seem to connect.

Please learn first the basics about what the session is. http://php.net/manual/en/intro.session.php

Should I use a $_GLOBAL?
Thanks in advance.

Session IS within the $_GLOBAL

and this is the way todo it (regardless in which component of joomla)

Code Select Expand


$session = JFactory::getSession();
$previousValue = $session->set('myValue', $value,'myNameSpace');


and you get it like this

Code Select Expand


$session = JFactory::getSession();
$value = $session->get('myValue', myDefault,'myNameSpace');
