Upon registration, I wish to let the shopper to send me information if it is a non-profit, education, government or similar organization (to apply discounts on some products).
I have not found an elegant way how to do it.
I have created a custom field "Orgtype" (type "select") allowing the registering shopper to choose its type of organization. Then I will personally judge whether the shopper has set the correct type and set discounts accordingly (or set Orgtype back to normal shopper in the shopper's account). Since this moment, it would be nice to have Orgtype read only for the shopper - but it is not possible; the shopper can freely mess with the field at any time, which can be confusing.
Can someone advice a way how to do it better?
