Manual:User former groups table
↑ Manual:Contents | MediaWiki database layout | user_former_groups table |
MediaWiki version: | ≥ 1.18 |
The user_former_groups table stores the groups the user has once belonged to (will not contain groups the user had belonged to before MW 1.17). The user may again belong to these groups; check the table user_groups , if you want to know. This is used to keep MediaWiki from automatically adding users to groups from which they have been manually removed before. The table was added in r90749.
Fields
ufg_user
Key to user_id .
ufg_group
Name of the group, which the user was member of.
