Least hacky way to show a message only to anonymous users?

Hi all,

I need to show a message box with a link to the login page when people visit my start page: http://campus.onlineradiomaster.de

At the moment, this is done with the description box of the course root node. However, I can’t seem to hide this box if a user is already logged in – I couldn’t find any class names or IDs in the page source that indicate if one is anonymous or logged in. I would prefer not to mess around in the Java source code which generates the page (I don’t know Java and want to keep my system maintainable) – is there another way to achieve this?

Thanks in advance & kind regards,

Tobias Grasse

Hi Tobias

The most simple solution is to use two course elements at the top: one for guests and one for authenticated users.

- Add a course element “single page” below your root element "MOOC Start Info”

- Add an expert visibility rule "isGuest(0)=1” to make this page only visible to guest users

- Add a second course element “single page” below your guest start page

- Add an expert visibility rule "isGuest(0)=0” to make this page only visible to authenticated users

- On the root element "MOOC Start Info” select the display option to automatically activate the first visible course element

Using that approach you can style the guest and non-guest page as you want, I would recommend using two different HTML pages instead of the description box, you might want to add other information to the page for guest users as well .

Cheers

Florian
