Check if post/page/etc is restricted

Under “Settings” – “Other Settings” – next to “Admin hint text”, whatever you put in that hint text will show up next to (right corner) a post title or page label if that post or page is restricted. The hint is only visible to Admins.

Thanks, but I need to check via code. Something like if ( content_restricted() )…

Have a look at the wiki: https://github.com/GM-Alex/user-access-manager/wiki/Code-Snippets

For all available functions check the code. \UserAccessManager\AccessAccessHandler:: checkObjectAccess should be the right function.
