I have a form with id 45 (paragraph rich text field and attachment field) and a form id 38. In the form id 38 I have an email field id 3 where I collect email addresses.
When I submit form id 45, it should send the data to all email addresses on form id 38.
Did you end up finding a workable solution for this?
I would think using gform_notification to get the email addresses from form #38 via the GFAPI wouldn’t be too complex. Although it could have a concern about avoiding having too many on the to: or bcc: for a single message.
If you use Gravity Flow gravityflow_notification is identical in concept to that filter. However, gravityflow_step_assignees would let you select the emails as assignees and each would receive their own notification.
