URE creates/edits user roles via WP API or directly in WP database.
Every role has 2 attributes: id and name in terms of URE’s user interface or in terms of WP API name (id) and display_name (name).
Look at the wp-includes/class-wp-roles.php:
public function add_role( $role, $display_name, $capabilities = array() ) {
if ( empty( $role ) || isset( $this->roles[ $role ] ) ) {
return;
}
$this->roles[ $role ] = array(
'name' => $display_name,
'capabilities' => $capabilities,
);
if ( $this->use_db ) {
update_option( $this->role_key, $this->roles );
}
$this->role_objects[ $role ] = new WP_Role( $role, $capabilities );
$this->role_names[ $role ] = $display_name;
return $this->role_objects[ $role ];
}
WP_User object which you can get from wp_get_current_user() contains roles property, which contains the list (array) of roles (ID) granted to user.
