HI,
I"m using Ninja forms and I need to only allow submissions from one specific domain, for example email@domain.com
If anyone can point me in the right direction for this, it would be greatly appreciated. I have found javascript and jQuery scripts that do this, I'm just not sure exactly
1, How to get the scripts working with Ninja forms
2, How to set it so they don't disappear if Ninja forms has an update.
Thanks,
