I need to link in the registration of each new host through the mandatory information of a numeric or text field, with a length of 11 characters, which I will call CPF.
However, if the new host has been indicated by another host (already registered) I would like to include other optional information in the numeric or text field, with a length of 11 characters, which I will call CPF_LINK.
How can I include and customize these new fields in the hosts register?
Note on screens 01 and 02, how the CPF and CPF_LINK fields will be included.
After confirmation of registration by email, the host informs EMAIL, PASSWORD and CPF
The value of the CPF field is transported to screen 02, and there is a new CPF_LINK field to be filled in.
