    Allow and Prevent Duplicate while filling form - Before Submission ??

    Asked by mongaakshay on July 15, 2016 at 01:24 PM

    Hi

     

    Is it possible to somehow prevent duplicacy between two fields ?

    Meaning, if I have 2 fields, say 

    Primary Mobile Number 

    Secondary Mobile Number

     

    and I want to user to fill two different values and not same ?

     

    Can I achieve this, without actually submitting the form ?

     

     

    Also, if I want the user to fill two exactly same values like

    Email Address

    Reconfirm Email Address

    Here the user has to fill the same email address again. 

     

    How can both these be achieved through JotForm ?

    and prevent duplicate allow before submission

    You can use Confirm Email field of JotForm, for achieving the functionality of making 2 emails exactly same.

    Check this user guide https://www.jotform.com/help/147-Adding-an-Email-Confirmation-Field

    Just set to YES the Confirmation option in your jotform E-mail field.

     

    For preventing duplicacy between two fields, you can use Conditional logic And can create a condition, which checks the value of 2 fields should be different.

    You can also hide "Submit" button if the value of 2 fields (Primary and Secondary Phone) are same. And can show a message regarding duplicacy notification instead of Submit button. 

    If you face any issue, or need further assistance, please feel free to revert back.

    Thanks.
