Changeset 35339 for trunk/src/wp-includes/comment-functions.php

Message:

Comments: Introduce two new filters, notify_moderator and notify_post_author, both of which make it possible to selectively override site notification email settings for new comments.

The notify_moderator filter makes it possible to override the value for the moderation_notify option, which controls whether to send new comment emails to "site moderators", that is to say, the owner of the admin email for the site and the post author if they have the ability to modify the comment.

The notify_post_author filter likewise makes it possible to override the value for the comments_notify option, which controls whether to send new comment emails to the post author. If the post author is the comment author, default behavior is not to send the notification. Note: enabling or disabling notifications via this hook could also affect other recipients added via the 'comment_notification_recipients' filter in wp_notify_postauthor(), if hooked.

Passing a falsey value to either of the new filters will prevent notifications from being sent, regardless of their corresponding option values.

Adds tests.

Props coffee2code, adamsilverstein, DrewAPicture.
Fixes #761.
