This ViewHelper checks to see whether the current page visitor (backend user) is authenticated or not. According to the
result of the check, the content of the subsidiary
f:else ViewHelper will be parsed.
This feature is predominantly used in the front end of the website: you can check whether the website visitor is currently authenticated as a backend user. A good example of a possible use case is for a front end editing tool, which should only be made available to a validated, logged-in backend user.
This ViewHelper doesn't accept any properties.
<f:be.security.ifAuthenticated> <f:then> You have permission to edit this content. </f:then> <f:else> You must log in if you want to edit this content. </f:else> </f:be.security.ifAuthenticated>
<f:be.security.ifAuthenticated> You are seeing this message because you are logged in as a backend user. </f:be.security.ifAuthenticated>
