Conditional registration in Zuddl lets you tailor the journey each prospect sees—showing or hiding questions, unlocking ticket tiers, or surfacing discounts—strictly when the logic you define is met. The net result is shorter forms for most users, cleaner data for operations, and precise control over scarce inventory.

​
1 · Field-level logic

Inside Registration › Form you can attach a rule to any custom field (standard fields like First Name, Last Name, and Email remain static).
Create two or more custom fields, then click Add Logic on the second one. A three-step wizard appears:
  1. Choose the earlier field that drives the rule.
  2. Pick an operator—is, is not, contains, does not contain, all of the, any of the.
  3. Select the value(s) that satisfy the condition.
When the rule evaluates true, the target field renders; otherwise, it stays hidden. Because logic references only fields that appear above the target, re-ordering a form after launch can break dependencies—Zuddl flags this risk in the editor. Use field logic to ask dietary restrictions only from in-person attendees or request a shipping address only when someone chooses a swag-eligible ticket. Conditionsreg Pn
