I have some additional fields in my registration WordPress form that I also have in my newsletter sign up form. Is it possible to pass the values of this fields to the newsletter form?
I would be amazing that the additional data option of the plugin allow to pass dinamic $_POST vars. I see that I can configure additional data as static vars with the key/value attributes, but I don't figure out how to configure them as dynamic vars that get the value from the form inputs.
If there is a way to make what I want with the current plugin version I really would appreciate you to help me.
