This feature enforces uniqueness for a field value in miniExtensions form. For example, if you would like to disallow a registered user from signing up again, this extension will prevent having duplicated records.

In miniExtensions form, you have the option to set a field settings to require uniqueness. In which case, the field input value will be validated. If the new value does not exist already, the record will be created/updated. If it does exist, an error message will show to the user and the form will not get submitted.
