When user groups are loaded, for example when a backend editor’s groups and permissions are calculated, a new PSR-14 event AfterGroupsResolvedEvent is fired.

This event contains a list of retrieved groups from the database which can be modified via event listeners. For example, more groups might be added when a particular user logs in or is seated at a special location.


This event acts as a substitution for the removed TYPO3 Hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauthgroup.php']['fetchGroups_postProcessing'].


class TYPO3\CMS\Core\Authentication\Event\AfterGroupsResolvedEvent

Event fired after user groups have been resolved for a specific user

Return type:string
Returns:‘be_groups’ or ‘fe_groups’ depending on context.

List of group records including sub groups as resolved by core.

Note order is important: A user with main groups “1,2”, where 1 has sub group 3, results in “3,1,2” as record list array - sub groups are listed before the group that includes the sub group.

Return type:array
setGroups(array groups)

List of group records as manipulated by the event.

  • $groups (array) – the groups

List of group uids directly attached to the user

Return type:array

Full user record with all fields

Return type:array
