    Duplicate submissions

    Asked by sharuvman on February 13, 2013 at 10:16 PM



    Is there any feature where in form prevents duplicate submissions ?.


    Eg: I want only two fields to be entered by a submitter. One is ID ( number ) and another Option (Text). The form I create should be able to prevent same ID entering the option again. Is it possible ?

    Unfortunately we do not have duplicate data check feature or something similar to that, therefore it is not possible. A possible workaround is to enable unique submissions with your form. This way, the user can only submit 1 submission entry per IP or per browser depending on the level of unique submisisons you've set. It is explained on this guide: How to Setup Unique Submissions of a Form

    Let us know if you have any other questions or concerns. Thanks!
