Custom User Field Overview
Custom user fields allow you to capture user-specific data that can be used to populate fields on variable text products. You may configure the type and kind of data, as well as the data field name and label. Buyer users may enter their data in a required or non-required text box, select from a drop-down list or via radio buttons, or browse to locate a file.
For example:
Your customer includes a web address on each business card. There is a generic web address that can be used by default, but if the buyer user has a custom website the user is allowed to change what will appear on his business card.
With the proper configuration, the user will see the default web address and be able to update it if he so desires.
The value in that field can then be used as a default value for a variable spec in a variable text product which reduces data entry errors and reduces the time required to order a product.
