Joomla 2.5 has reached its end of life as for 12/31/2014. Please be advised this may be a security risk to your website. You can view more information about the end of life here.
In a previous article, we began discussing the basic fundamentals of Joomla 2.5 ACL, Access Control Lists. We covered that the Access Control Lists are based upon:
- Users
- User Groups
- Access Levels
- Core Permissions
In this article, we will cover in more detail the Core Permissions of Joomla’s ACL.
When assigning rights / permissions to a user group, you are in essence toggling the Core Permissions available within the Access Control Lists. These Core Permissions include:
| The Joomla 2.5 Core Permissions: | |
|---|---|
| Site Login | Site login controls whether a user can log into the front end of your website |
| Admin Login | Admin login dictates who can log into the administrative end of your website |
| Offline Access | Offline Access sets who can see the website when it is set to offline mode |
| Super Admin | Super Admin privileges are similar to root access. Super Admin can do anything, which naturally includes overriding ACL settings |
| Access Component | Access Component gives rights to users for specific areas in the administrative interface, such as managing menus and components |
| Create | The right to create allows users to create new content |
| Delete | Delete controls which users can delete content |
| Edit | Edit allows users to edit any content, regardless of whether it is their own content or not |
| Edit State | Edit State allows a user to change the state of content, such as being published, unpublished, and even trashed or archived |
| Edit Own | Edit own allows them to edit content they’ve created. They can only edit their own content, they cannot edit content created by others |
All users groups have the ability to be given these core permissions. For example, if you go to Joomla Admin >> Global Configuration >> Permissions, you’ll see that all user groups show the same core permissions:
| Registered Users | Super Users |
|---|---|
| As you can see below, both Registered Users and Super Users share the same 10 core permissions. | |
 |  |
In future articles, we’ll cover more on how to toggle core permissions on / off for specific user groups.
