In the Standard questions of the Lyyti registration page, there is a question called Personal ID, which requires the answer to be in the form of a Finnish personal identity code. For security purposes, information on personal IDs are deleted when the event is archived. There isn't a standard question for date of birth, so if you wish to ask a question for the date of birth in the format mm.dd.yyyy or yyyy.mm.dd or any other format, you can do this instead:
- Create a Short text field. As the question text, put in something like "Birth date (dd.mm.yyyy/wished format)"
- In Validation of answer, select String
- In the opening section, select Allowed characters to be Numbers and Number of characters to be 10 - 10
Now the participant is obliged to write exactly 10 characters into this field, in some format of dd.mm.yyyy. Technically it is possible that they write 10 characters of anything, but usually when asked for a specific format, the correct one is provided. The validation of the answer text, the allowed characters and number of characters restricts the answer given so that it is only possible to answer in one way. If the person answered 'incorrectly', meaning that the format of the answer is wrong, the person will receive an error message. If they write June 3rd, 1980, or 11.5.83, Lyyti will inform them that their answer is not in the correct format.
