Hello!
I'd like to know how to add a repeater group on an existing post when submitting a different form?
The use case is something like this:
A CPT acts as an item, part of a rental inventory. Then another form (another CPT perhaps) is used to checkout that item. When that occurs, add to the item a note with the data/details of the checkout (the repeater group). With this, when viewing the item post, you can see the "history" of how many times and who checked it out and such.
Thank you!
.
