Hi, I made a registration form successfully with pie-register where invitation codes are needed because there is a pre-made Member IDs I made and used them as invitation codes to validate them.
However, I don’t need the codes just for registration but also to become a particular member ID. My question is, how can I use the invitation code used by the user in his/her registration to be displayed in my website using shortcodes or other means?
A result I’m looking for is like:
Member ID : 412312
