You can use this to add the current blog ID and / or current user level to your body class. It can be modified in any way of course.
Add blog ID to body class
function add_blog_id_body_class($classes) {
$classes[] = 'blog-'.get_current_blog_id();
return $classes;
}
add_filter('body_class','add_blog_id_body_class');
Add current user level and role to body class
function add_user_role_body_class($classes) {
global $user_level;
global $current_user;
$user_roles = $current_user->roles;
$user_role = array_shift($user_roles);
$classes[] = ' user-role-'.$user_level . ' ' . $user_role ;
return $classes;
}
add_filter('body_class','add_user_role_body_class');
All together now!
function add_body_classes($classes) {
global $user_level;
global $current_user;
$user_roles = $current_user->roles;
$user_role = array_shift($user_roles);
$classes[] = 'blog-'.get_current_blog_id().' user-role-'.$user_level . ' ' . $user_role ;
return $classes;
}
add_filter('body_class','add_body_classes');
