qvia Posted April 9, 2014 Report Share Posted April 9, 2014 Is it possible to ensure that the data entered by a customer into a certain custom field is unique. Ie. checked against previous stored entries? To give an example, I don't want two customers with the same postal/zip code (this postal/zip code will be an added custom field). Can this be done through the JSON input rules? Anniezet and Flynnnan 2 Quote Link to comment Share on other sites More sharing options...
Tyson Posted April 9, 2014 Report Share Posted April 9, 2014 No, the input rules in the Universal Module couldn't handle this because it would require the use of a custom, user-defined, method to evaluate the uniqueness of a field by querying the database.
