Hi there,
I have found a solution when the item is created with Seblod.
What we did (with the help of Seblod team) is created a file in
/media/cck_dev/processings/acymailing/
This file is to determine which user is going to recieve the email and selecting the good article to send him : the one of a specific category where he is the author of the article, and then concat the content (fields from the Seblod form) for the Newsletter itself.
I was wondering if there's not a similar solution for Joomla core article.
Of course, I need tips for that as I'm not able to do it alone. But some URL (?) or advice can be enough. I will just come back with questions :-)
Any idea?
