Using Data Builder Action to save/retrieve session data

Hi,
​
I understand that the Data Builder action is now used to save session data.
​
So I placed a Data Builder Action, and in the Value section selected "Session" and gave a name "ss". Put nothing in the value field.
​
Then in the page where I wanted the session data back, I placed
​
$sessiondata = \GApp::session()->get("ss", "");
​
which used to work, and still does in forms which are still using the old style.
​
But now it is empty - no data is returned.
​
What am I doing wrong?
​
Cheers
​

I have found the answer, so no need for a response.
​
In the Data builder the "value" field needs to reference the data to be saved. so, in the value field place {data:somefield} or {var:somevar}.
​
The the retrieval code
​
$sessiondata = \GApp::session()->get("ss", "");
​
recovers the data as required.
​
I wonder if there is a shortcode that will save the entire session data?

Actually I did try {data} .. but I forgot the colon.
​
Anyway, all good now.
​
Thanks.

Also you can use {session:xxx} to retrieve your session data (but obviously not in PHP)

Hello again, just wanted to double check if you meant by {session:xxx} to be inserted into action as a custom code or what exactly.
I have already tried it but the session still sends old value.

in a nutshell I dont want to retrieve the data only , but I want actually to set the prev session data into the current session. is this possible at all?

Yes I meant in Custom Code action, or wherever you want to use it (like the save data action), just not in PHP. {session:namegoeshere} will retrieve the session, {session.set:namegoeshere$valuegoeshere} sets it.
​
Or {session.set:namegoeshere$(data:fieldnamegoeshere)}
​
Or use the data builder 2 action.

thanks alot for clarification
