Profile 1.68 is a version of Profile module for XOOPS that allows for a verbose registration to be done.
This has a field for validation that allows for Text Match, RegEx or SQL Validation to be used to prevent people registering with your website without having validation data of sometype such as an existing email address or an invite code or some regular expression statement.
Featuring still Multiple Fields, 2 Types of validation - one which uses JSON; the other that uses the Field $_POST validation method.
Simply upgrade your existing XOOPS 2.4 or 2.5 to XOOPS Profile 1.65 to experience the difference. We can really recommend XinCodes 1.05 for a user based invitation to be done.
