Manual:user_properties table

Manual:Contents MediaWiki database layout user_properties table
MediaWiki version:
1.16

The user_properties table stores user preferences . It replaces the old user.user_options blob. Only non-default settings are stored, so changes to the defaults are now reflected for everybody that hasn't saved an alternative preference, not only new accounts.

FieldsEdit

up_userEdit

Foreign key to the user_id field of the user table.

up_propertyEdit

The user preference, see Manual:$wgDefaultUserOptions . Examples: gender, watchcreations

up_valueEdit

The preference value.
