    How to prevent 2 people from using the same email when submitting a form.

    Asked by lebaus on September 29, 2013 at 02:05 PM

    I need to prevent The first guest and second guest from using the same email address. How can I do that? I need them to submit completely different emails so that I can send each of them paperwork to E-sign individually.

    Hello,

    Unfortunately, this email verification on our form us not currently available feature we have.

    We only have the IP validation where the system will detect multiple session and won't let double submission by the same user via checking the IP address of the computer.

    But checking according to email is not yet available as of this moment.

    Kindly let us know if there is anything else we could help you with.

    If it is a new topic, we recommend that you open a new thread to assist you better and avoid any confusion.

    Thank you for using JotFom. :)

    No, I don't want 2 people who are both listed on the form to use the same email, like a husband and wife. So if the first person uses and email, the 2nd person must use a different email.

    One solution for this would be to use our Unique Question feature where each email address submitted must be different, as in this demo form. Submit it using an email address and then try to use the same email again.

    Please see How to set Form Limits Based on a Unique Question for details on how to use the feature.


    Thanks

    My apologies. Now that I've examined your form, the solution mentioned won't work. Since our product has no "comparison of field entries" feature, you would have to resort to embedding the form's full source into a web page and adding a custom script to compare the entries. I believe I can come up with such a script.

    I'll be back.

    Hi again,

    Please have a look at this page that contains a clone of your form and test its functionality. If the primary and 2nd guest emails match, the Submit and Print Form buttons become hidden and an alert is triggered. If the source of the page is viewed, you'll see this script near the bottom, just before the closing body tag.

    To use the solution with your own form, get a copy of its full source and embed it into a web page of your choice. Then copy the script and paste it at the bottom of the page, right before its closing body tag, just like in the demo.

    If you need clarification on anything or would like adjustments to be made to the script's functionality, we'd be happy to help.


    Thanks
