Preventing submitting form twice

Hello,

I am interested if there is a way to prevent submitting the form twice if the lead already exists (for example based on email as a unique identifier)

and if possible showing the corresponding message

thank you

There are unique fields (email is default) allow merging contacts

https://www.mautic.org/docs/en/contacts/managing_contacts.html#contact-duplicates

and that’s exactly what I am trying to avoid -merging a contact because when you merge you overwrite the old data in the fields with new data.

In my situation, when a new contact enters his email I grab some extra referral data and if he comes back again and enters the email again the original referral data gets overwritten with the new referral data and I don’t want that… So I either I need to prevent submitting the form if the contact already submitted it once or somehow lock the fields if they are populated already

This feature is on the upcoming list

that’s great! Is there any schedule to have any idea when?

Any solution on this? Subsequent submitting of a form overwrites the existing data…
