WordPress: Add user role class to body tag

wp-role-bodyclass.php

<?php

// Add role class to body
function add_role_to_body($classes) {   
    foreach (wp_get_current_user()->roles as $user_role) {
        $classes[] = 'role-'. $user_role;
    }
    return $classes;
});
add_filter('body_class','add_role_to_body');
add_filter('admin_body_class', 'add_role_to_body');

?>

@joanna-s thank you!!

This works for serveral user roles per user....
`function add_role_to_body($classes) {

global $current_user;
foreach ($current_user->roles as $user_role)
	$classes[] = 'role-'. $user_role;

return $classes;

}
add_filter('body_class','add_role_to_body');
`

Here’s @santiazpi’s code with the syntax highlighting fixed, plus refactored to use a function expression as the callback:

add_filter("body_class", function($classes) {
    global $current_user;
    
    foreach ($current_user->roles as $user_role) {
        $classes[] = "role-{$user_role}";
    }

    return $classes;
});

FYI, here’s how to add role classes in the WP admin:

add_filter("admin_body_class", function($classes) {
  $user = wp_get_current_user();
  foreach ($user->roles as $user_role) {
    $classes .= " role-{$user_role}";
  }
  return $classes;
});

Thanks @tedw I've updated the gist using your second function which seems to be compatible with the frontend theme as well.

Agreed, I used the first snippet posted by @tedw and it works perfectly on the frontend. Don't really need the role as body classes on my WP Admin.

Thank you @tedw it works great!
