Detailed Description

A provider for resolving fe_groups / be_groups, including nested sub groups.

When fetching subgroups, the current group (parent group) is handed in recursive. Duplicates are suppressed: If a subgroup is including in multiple parent groups, it will be resolved only once.

this is not part of TYPO3 Core API.

◆ fetchGroupsRecursive()

TYPO3\CMS\Core\Authentication\GroupResolver::fetchGroupsRecursive ( array  $groupIds,
array  $processedGroupIds = [] 

Load a list of group uids, and take into account if groups have been loaded before.

◆ fetchParentGroupsFromDatabase()

TYPO3\CMS\Core\Authentication\GroupResolver::fetchParentGroupsFromDatabase ( array  $subgroupIds)

Find all groups that have a FIND_IN_SET(subgroups, [$subgroupIds]) => the parent groups via one SQL query.

◆ fetchParentGroupsRecursive()

array TYPO3\CMS\Core\Authentication\GroupResolver::fetchParentGroupsRecursive ( array  $groupIds,
array  $processedGroupIds = [] 

Load a list of group uids, and take into account if groups have been loaded before as part of recursive detection.

int[]$groupIds‪a list of groups to find THEIR ancestors
array$processedGroupIds‪helper function to avoid recursive detection
‪array a list of parent groups and thus, grand grand parent groups as well

◆ fetchRowsFromDatabase()

array TYPO3\CMS\Core\Authentication\GroupResolver::fetchRowsFromDatabase ( array  $groupIds)

Does the database query. Does not care about ordering, this is done by caller.

‪array Full records with record uid as key

◆ findAllUsersInGroups()

array TYPO3\CMS\Core\Authentication\GroupResolver::findAllUsersInGroups ( array  $groupIds,
string  $sourceTable,
string  $userSourceTable 

This works the other way around: Find all users that belong to some groups. Because groups are nested, we need to find all groups and subgroups first, because maybe a user is only part of a higher group, instead of a "All editors" group.

int[]$groupIds‪a list of IDs of groups
string$sourceTable‪e.g. be_groups or fe_groups
string$userSourceTable‪e.g. be_users or fe_users
‪array full user records

◆ resolveGroupsForUser()

array TYPO3\CMS\Core\Authentication\GroupResolver::resolveGroupsForUser ( array  $userRecord,
string  $sourceTable 

Fetch all group records for a given user recursive.

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.

array$userRecord‪Used for context in PSR-14 event
string$sourceTable‪The database table to look up: be_groups / fe_groups depending on context
‪array List of group records. Note the ordering note above.
