    How to stop repeat submissions?

    Asked by hankenb on January 12, 2011 at 10:15 AM

    In my form, I only want to be able to let the user submit the form once. I want to check the email address and make sure they have not already submitted a form. My site rewards form submissions, so naturally I don't want people taking advantage of this. Thanks.


    Edit-I just saw from the manual that I can set in the preferences to "Loose" or "Strict" and these options will prevent multiple submissions by checking against the IP address. Is there a setting to make it check against email instead?

    Click on "Preferences" button on the toolbar, then change "Unique Submissions" to "Strict Check".


    These will use cookie or IP address to check. There is no check based on the entered email address.
