Unique Question :: Can you have more than one?Asked by rebirthdesign on February 27, 2014 at 02:29 AM
What to do if you want to limit both email addresses and say another input field so that they are both unique (i.e., username)?
Can I code this via the source?
Unfortunately, we do not have such feature. You can have only one unique question in your form.
This cannot be achieved through source code as you will not get the list of submission data to find if the current record is actually an unique one.
Actually there is one possibility. This would require programming effort but you can take advantage of our APIs to make API call to get the submissions and write you own login to find out if the current input data is actually unique. The following guide should help you: http://api.jotform.com/docs/
