Problem: I have a Form that creates child posts. When the child post is published, I would like to send an automatic email notification to an email address specified in the parent post's custom fields, but I cannot specify that field in the notification settings.

Solution: You can use some custom PHP code with the cred_notification_recipients API and the toolset_get_related_post API to query the parent post, get the custom field value, and add that email address to the recipients list programmatically:
