Hi,
May i know if someone ever done this. I've make one form for a contest where user can submit their detail, subscribe to our newsletter and upload their receipt of purchase. But one issue that i found out where when a same user re-enter the contest using same detail only the different receipt of purchase, their old uploaded file are missing from backend. Is there anyway that i can solve this issue where the file are not overwritten so we can see multiple receipt of purchase from the same user?
Thanks.
