How could I find out how many users have each email setting?
I’m asking as only about a tenth of users watching a topic are being emailed post notifications.
Thank you.

هل تقصد تلك الموجودة في صفحة التفضيلات/البريد الإلكتروني الخاصة بهم؟ يوجد هذا الحقل في جدول user_options (email_level)، وهناك أيضًا حقل الرسائل الخاصة (email_messages_level).
أعتقد أن هذا يعمل. فهو يستخرج المستخدمين الذين يتابعون موضوعًا معينًا، ويحصيهم حسب مستوى البريد الإلكتروني:
| مفتاح | مستوى البريد الإلكتروني |
|---|---|
| 0 | دائمًا |
| 1 | فقط عندما تكون بعيدًا |
| 2 | أبدًا |
-- [params]
-- int :topic_id
SELECT tu.topic_id AS topic_id,
uo.email_level,
COUNT(*)
FROM user_options uo
JOIN topic_users tu ON tu.user_id = uo.user_id
WHERE tu.notification_level = 3
AND tu.topic_id = :topic_id
GROUP BY topic_id, uo.email_level
أخبرني إذا أفسدت الأمر. ![]()
![]()

أعتقد أن هذا يعمل أيضًا: (ويعرض بشكل أفضل قليلاً)
