I am trying to create a user login system, where the use can log in and be put in different groups. Depending on the group they are in, they are allowed to access certain functions (group based permissions). I have been trying to follow these (http://www.yiiframework.com/extension/acl/) instructions, but I just need help on how to actually use it.
How do I add a user to a group?
How do I test if the user is added to that group?
