Access-Manager can set frontend viewing rights to multiple accesslevels / usergroups.
Access-Manager manages access to:
# viewing of content (extending Joomla's viewing access)
++ parts of content
++ admin menu items
# editting of content (extending Joomla ACL)
No - I'm not related to Carsten (!) but I'm a huge, huge fan of his work - it makes life for site builders SO much easier!
We had one problem with another module not behaving when I enabled Access Manager, but I contacted Carsten and he solved the problem within 24 hrs, GREAT support.
In the backend of Joomla i can pick any user and assign them to a group level. It can even be a Special group that i created.
This special group can have access to multiple levels
For example i can create a group called "Special Access"
and set this group to match the access of
Registered , Author, Manager.
All at the same time
or any other configuration i choose. Then just assign specific users to this group so why do we need this tool?
Please read this FAQ:
1. so you can set rights on groups instead of levels.
2. so you can reverse rights (selection has NO access)
3. Because in Joomla you can still only assign access to only ONE accesslevel per article/module/menu-item/etc. not multiple. You can create custom accesslevels, sure, but its a nightmare for schools and universities where the users are students and the groups are the courses they take. If there are 20 courses and each student takes on avarage 5 courses you need to make access-levels for EACH COMBINATION of groups. 1-2, 1-3, 1-4 etc. 2-3, 2-4, 2-5 etc. 1-2-3, 1-2-4, 1-2-5 etc. You get the picture, that is 100+ accesslevels, that is totally unworkable. And you would still need double content, which is a nightmare for administrators and users.
In Access-Manager you can set access to as many groups (or levels) as you like. So in the above case you would need only 20 groups.
4. To do ACL stuff that is not in the Joomla core (yet).
5. Access-Manager can set custom actions if the user has no access.
6. Joomla usergroups ALWAYS inherit rights, which can be a pain in the rear, in Access-Manager groups don't inherit, so you are in control.
