actions_synchronize

Versions
6
actions_synchronize($actions_in_code = array(), $delete_orphans = FALSE)
7
actions_synchronize($delete_orphans = FALSE)

Synchronize actions that are provided by modules.

They are synchronized with actions that are stored in the actions table. This is necessary so that actions that do not require configuration can receive action IDs. This is not necessarily the best approach, but it is the most straightforward.

▾ 4 functions call actions_synchronize()

system_actions_manage in modules/system/system.module
Menu callback. Display an overview of available and configured actions.
system_actions_remove_orphans in modules/system/system.module
Remove actions that are in the database but not supported by any enabled module.
system_modules_submit in modules/system/system.admin.inc
Submit callback; handles modules form submission.
trigger_install in modules/trigger/trigger.install
Implementation of hook_install().
