#31304 closed enhancement (invalid)

Add wrapper function to check if a given role exists

Currently, the only way to check if a user role exists in the database is to use get_role() and check if the result is null or not. While that isn't too complicated to do, I think it would be useful to have a simple wrapper function that performs this check so that developers can easily check for a role before manipulating it (adding capabilities, etc.).

In case this ticket awakes again, here's a summary from the discussion in the Slack Channel.

  1. Return strict and just the result as it evaluates to bool anyway.
  2. Use \WP_Roles::is_role( $role )


 * @param string $role
 * @return bool TRUE if the role exists
function role_exists( $role )
    /** @var \WP_Roles $wp_roles */
    global $wp_roles;
    return $wp_roles->is_role( $role );
