    How to prevent double/multiple submission

    Asked by agenziadantealighieri on September 17, 2015 at 07:00 AM

    Hello, every day we find many double submissions (3/4 times too).

    What is the matter? The user who proceed with double-click on "send" button?


    Any idea?

    I have checked your website and found this form: http://www.jotformpro.com/form/52382630902956

    It might be possible that the users of your form submitted your form multiple times or it can also be a spam. 

    I am thinking that the duplicate submissions are being caused by spam. And is only possible if your form is embedded on a website. If you are using the form directly from JotForm (form URL), the spam submissions will not happen. 

    I can see that there are required(*) fields on your form which is a good way to prevent spam. Another way to prevent spam is by adding a Captcha field on the form to make sure there is human intervention, and not just spam bots that are causing the re-submissions of the form.
