phpBB trick: automatic all forums subscriptions to all members

One small forum running on phpBB needed email subscriptions on all forums applied to all members. While it is easy to find a mod adding this feature, it is much more complicated to install a modifications to phpBB rather than vBulletin. Today I’m sharing SQL query accomplishing subscription task on database side.

insert into prefix_forums_watch
select distinct f.forum_id, u.user_id, 0
from prefix_forums f, prefix_users u
where not exists (select 1 from prefix_forums_watch
	where forum_id = f.forum_id
	and user_id = u.user_id) and u.user_type = 0

Instead of prefix correct value set during installation has to be entered. Default is phpbb.

Forum subscriptions are stored on forums_watch table which consists of three fields. Only two are important – forum identifier forum_id and user identifier user_id. Forums and users are stored on forums and users tables respectively.

I found this query at Stack Overflow and made one modification – added condition user_type = 0 which enables subscriptions only for regular registered users. Search bots are stored on the same table but there is no need to enable subscriptions for them.

    Great work here. This saved me a ton of time. I was able to achieve the desired results for my members in seconds. I used this to subscribe the moderators for the moderators then removed the unneeded tables. A little extra work.

    How would I modify this so that I can subscribe all users to a singe topic/post.
