Hi We're developing a customized application in our domain. Here, I want to validate WHMCS customfields with database values. how can we do that? My requirement is as below : I've created 2 custom fields i.e., Sponsor ID and PlacedUnder in WHMCS. these are displaying in Registration form. Now, I need to validate them with existing database values. And how these customfields are linked with Domain ? Because I'm taking domain as sponsor. Thanks in advance guys
