This recipe shows how to hide the action buttons for unauthorised and/or guest users:
(Edit, Attach …)
Note that the solutions in thic cookbook do not hide links to missing topics and unknown
WikiWords.
There are two options:
This is the recommended approach. Edit buttons will be visible for guests,
and will be hidden if a logged in user does not have access. This is the
most "friendly" approach in that a guest can click any button (for ex. edit or
attach) and will be prompted to log in.
This line loads the extra style definition:
* Set USERSTYLEURL = %PUBURLPATH%/%SYSTEMWEB%/PatternSkinCssCookbookHideActions/hideunauthaction.css
This requires guests to find and click the login button to authenticate before
the buttons become visible.
Note: This is not a good way to prevent search
engines from following edit links. The buttons are present, but are hidden
using CSS.
This line loads the extra style definition:
* Set USERSTYLEURL = %PUBURLPATH%/%SYSTEMWEB%/PatternSkinCssCookbookHideActions/hideguestaction.css
Alternative CSS
Another option is to leave the buttons present, but disabled. The following
CSS sets the opacity to 50%, and disables the button.
