In this course, author Jen Kramer uses access control lists (ACLs) to define and implement user permissions on a Joomla web site. The course covers granting access to front-end content, customizing a login page for different user groups, delivering specific content to certain user types, and creating a simplified back end. The course also includes tips and tricks for styling the offline access page and working with the ACL Manager extension.
Topics include:
- Introducing access control lists
- Defining users, groups, and access levels
- Assigning core permissions
- Creating users and assigning them to groups
- Assigning viewing access levels to modules, articles, and categories
- Customizing back-end editing for improving client usability
- Adjusting permissions for each category of content
- Hiding a site behind a login

Frequently asked questions
Find answers to the most frequently asked questions about Joomla! 1.7 and Joomla! 2.5: Access Control Lists in Depth.
- Q: After following along with the exercise files, all has gone well until I installed JCE. When I did this my control panel on the backend came up with the following "strict standards" error:
( ! ) Strict standards: Non-static method WFEditor::getInstance() should
not be called statically, assuming $this from incompatible context in
C:\wamp\www\administrator\components\com_jce\models\model.php on line 112
Please advise. I looked for a way of uninstalling JCE and could not find one. The exercise site seems to work quite well otherwise, although I can't change the profile of JCE as instructed because of similar messages throughout the JCE profile. - A: Anytime you receive an error about "strict standards" when work with WAMP (any additional messaging doesn't matter), please apply the following fix. This fix is also described in the Joomla! 3 Essential Training Chapter 11 video, "Turning off WAMP error reporting."
Because the error reporting is an issue with WAMP and not Joomla!, this fix works for Joomla! 1.6, 1.7, 2.5, and 3.0, as well as later versions of Joomla.
1. In WAMP, find the icon in the system tray and click it.
2. Choose PHP - php.ini from the list.
3. Search the php.ini file for the following line:
error_reporting = {there will be some kind of value in this place}
4. Change whatever value is there on that line to the following:
error_reporting = E_ERROR
5. Save and close php.ini, then go back to the WAMP menu and choose "stop
all services", followed by "start all services" to reboot Apache.
6. You should no longer see errors. If errors are still present, then do
the following:
a. follow steps 1 and 2 above
b. Search the php.ini file for the following line:
display_errors = off
Change this to
display_errors = on
c. Follow step 5 above.
