use $_session["userid"] in custom button

In PHP most things are case sensitive. If you are trying to use a built-in session variable $_SESSION["userid"] is incorrect while $_SESSION["UserID"] is correct.

Thank you for the reply. There is no case sensitive issue here, I am definitely missing something here and the documentation on tri part events is scarce.
I have declared the variable in after successful login but it is not used in the server event. I will continue digging, perhaps I can find a piece of useful info somewhere.

hi

$_SESSION['userid'] stores the user's name
in after successful login event, add

$_SESSION['nUserId']=$data['id'] (or whatever your id field name is)
then use $_SESSION['nUserId'] in your button
hope it helps,

Documentation is always the first to blame.
The problem is that you are trying to use $_SESSION["userid"] that conflicts with the system session variable $_SESSION["UserID"]. As Nir suggested - use another session variable name.
Better yet, if you are trying to use ID of the user from the login table, there is a recommended API for that:

Hi,
Will try your suggestions and update this topic with results.
Thank you very much for your advices.

It works with $_SESSION['userid']
It does not work with $_SESSION["userid"] (documentation here: https://xlinesoft.com/phprunner/docs/save_user_data_in_session_variables.htm)
