Sure, I'll have three separate forms across the site - all of which is to subscribe to our newsletter. We require two bits of information, first name and email address.
However, at the basket, we have a checkbox which says allows the user to subscribe (as by reaching the basket they will have created an account and we'd already have their data) hence why we have just a checkbox.
I desire to enter the data [first name, email] into a newsletter table.
So, we have three forms across the site and checkbox as points where I'd like to add functionality to insert record into newsletter table.
Hope this makes sense.
