Hello from a newbie!
I don’t understand how a data field is bound to a text box.
For example, if I have a text box to contain the email address, how do I tell it to save the entered data in the email data field. It appears to be automatic, since the email data field is a built-in field. However, how do I tell for example to store the user’s preferred language in the data field I called preferred_language in the user data table?
