How to display users in a group
PermalinkHow can I get a listing of groups and users.
Ver 5.6.1.2

Loader::model('user_list'); $ul = new UserList(); $users = $ul->get($numUsersToGet, $offset);
See more documentation about the user list model here:http://www.concrete5.org/documentation/developers/permissions/user-...
And you can get groups like this:
Loader::model('search/group'); $gs = new GroupSearch(); $groups = $gs->get($numGroupsToGet, $offset);
And you can see more info about groups here:http://www.concrete5.org/documentation/developers/permissions/group...
Or if you don't want to write any code you can do like SheldonB said and check out JohntheFish's magic data addon. I don't know much about magic data though so I'm not positive how you would accomplish this using it.
Hope that helps!
