Question:
When using the Wix Members Area app, prevent a duplicate member Display Name (nickname) from being created by a member.
Product:
Wix Studio
What are you trying to achieve:
I want the member Display name to be the unique identifier of the member so when a member enters data into forums and groups, they are uniquely identified. I need a way to validate the member display name when a member updates their profile. I’d like to prevent them from using a name that is currently being used by another member. It appears that the out-of-the-box functionality will allow multiple users to have the same Display Name and therefore appear like the same member in Forums and Groups.
What have you already tried:
Data Hook validation
