How can I transfer a variable value with CB auto-action from an action to another

hello
I have a variable ( a reference ID ) that I'm creating at CB auto-action "before login" , and I would like to transfer it and be able to use for another action " after login"
I can see in the parameters of CB-actions some variables but I don't find how to use them
Thanks for your insights !

If it's in the form POST data then a field action can store it fine and you can pull it from POST using [post_VARIABLE] (e.g. [post_referenceid]). Beyond that you'll need to better clarify how you're generating this variable, where, and what scope it's available to (e.g. is it in GET, POST, PHP variable?).

Hi ,
Thanks for your answer.
In fact, it is linked to my other topic.
Before login, I generate a sessionID reference, that I want to pass accross pages to be able to use in a new CB-Action : after login , using a PHP script then

1 - user arrivs on login form
2 - CB action : generate sessionID
3 - user logs-in
4 - I have sessionID var avialble to use for some PHP script

Thx !

You need to store the ID somewhere so it can be accessed across pages. The best bet is to store it in their Joomla session and then you can access it reliably until they log out. Why is this needed? Joomla already handles a session id per user.

Hi
I call it sessionID as a bad translation to english. let's call it : referencedeviceID
I'm implementing a devicefinger printing solution and I need to make a relation between the scan and the check ( after the login ) , which is this referenceID

Do you mean then something like that :
$session = JFactory::getSession();
$session->set('myrefID', '1234567890'); ?

And then, when needed , this ?

$MyrefID = $session->get('myrefID');

Hi,
After few debugging , I found why my ID are not matching where I though it was issues on variable sharing accross pages ...
Here is the code implemented regarding ID generation and sharing.
With the "debugging" as error output ( see attached ) , I can see the code being run multiple times... and then so, ID regenerated ( double checked, the 1st geenration is working well for javascript usage )

here is the code ... no loop or anything, why is it run multiple times ? Thx !
