With only node id, how can I get email address in user field on document belongs to ?
Hello
I would like to create trigger
in script I want to get email address in document's user field
trigger is triggered when node is changed, so I only know node id.
with this node id, I can get document's ID using API.
but I have a problem getting email address in user field on document.
below is my plan to getting user email address
(1)node(2nd level) ID -> (2)node(1st level) ID -> (3)document ID -> (4)user field list -> (5)user email address
I achieved only (3)
Thank you in advance
