In the days of CRED forms, this hook worked to send an email to the author of the parent post when a child post was created:-

add_filter('cred_notification_recipients', 'ts_cred_notification_recipient_428', 10, 4);
function ts_cred_notification_recipient_428($recipients, $notification, $form_id, $post_id){

	 // This is the Review_Listing_Create form ID     
    if (428 == $form_id){
        $parent_slug = "parentpost";
        $field_slug = '_wpcf_belongs_' . $parent_slug . '_id';
         
        $parent_post_id = get_post_meta($post_id, $field_slug, true);
        $post_email = get_post_meta($parent_post_id, 'wpcf-email-address-parentpost', true);
         
        $recipients[] = array('to'=>'to', 'name'=>'', 'lastname'=>'', 'address'=>$post_email );
    }
    return $recipients;
}

How do we implement this in the new world of Toolset forms?

Hi Julie

See my recent answer to your other question about whether you are using existing forms or creating new forms and need to replicate this functionality.

The answer is essentially the same, that in place of the get_post_meta call for the _wpcf_belongs_parent-slug_id field, you need to get the parent ID using the toolset_get_related_post method of the new relationships API:

https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_get_related_post

If you need help with the specifics of the code, let me know.

Hi Nigel

Thanks for this; I have additional queries but will add them to my other post (https://toolset.com/forums/topic/populate-child-post-title-with-parent-post-title/)
