TIP: Mass Delete inactive users with no posts

Post by mamba » Wed Jun 15, 2005 3:54 pm

This command, issued in phpmyadmin, will get rid of the rubbish on your users file: the people who never completed their registrations (inactive) and have never made any posts (as opposed to those who are inactive now but were once active and do have posts). The code also protects against the deletion of the Anonymous User. I have also built in a limit so that you can avoid deleting people who recently partially registered and may still become active.

Code: Select all

DELETE FROM `phpbb_users` WHERE (`user_posts`=0 AND `user_active`=0 AND `user_id`!=-1 AND `user_id` < [number])
Take a backup first!

Note: change [number] to some thing like 8768 (no square brackets) based on your table's most recent user_id values, so as not to delete recent partial registrations.

This code means you do not have to install an irritating PRUNE USER MOD.

here's another approach based on mamba's idea:

Code: Select all

delete from phpbb_users where user_posts=0 and user_active=0 and user_id!=-1 and from_unixtime(user_regdate) < now() - interval '1' day;
gets rid of anyone who has started registration over a day ago and still hasn't activated. any real user is likely to have registered as soon as possible. less guessing games with user_ids, you can cut & paste directly or even run as a cronjob (as i do).

adjust the interval if you feel it's too short (or too long, in my case i use interval '6' hours, i expect anyone registering in my forum to complete their registration within a few minutes and if it fails well, they can always try again in 6 hours...)

Thanks guys, I will try this and wondering why it is not included in the same manner as the "forum clean up" feature.

Deleting users this way leaves stuff behind in the forum... namely the single-user user groups created for each user.

It's much safer to use the Starfoxtj Tool Kit to fix a lot of Admin-related problems, which has the ability to sort users by last access, number of posts, etc., and do mass deletes SAFELY, including cleaning up after itself.

I am sorry using phpmyadmin to delete users from the phpbb_users table is wrong as it does not remove everything relating to the member being deleted. Unless you know what you are doing please do not post such advice and certainly do not use it :) If you want to mass delete members please use a mod which does just that, but does it properly removing everything. Seens as there was not a support request here and the original posts were bad advice i am closing this one
