Changeset 6100 for trunk/bp-groups/bp-groups-cache.php

Timestamp:

Message:

When a group is created or deleted, clear each group member's "total groups count" cache.
Addresses a bug where the counts never changed in an environment with a persistent object cache.

• See #4226
• Specify cache group for to wp_cache_delete() in groups_clear_group_user_object_cache().
• Add $user_ids parameter to the 'bp_groups_delete_group' action to save a repeat DB query later.
• Add $group object parameter to the 'groups_created_group' action.
