Login/Logout in Menu

Hi Guys

I have the following code in my functions.php for adding a login/logout to my menus

add_filter('wp_nav_menu_items', 'add_login_logout_link', 10, 2);
function add_login_logout_link($items, $args) {

ob_start();
wp_loginout('index.php');
$loginoutlink = ob_get_contents();
ob_end_clean();

$items .= '<li>'. $loginoutlink .'</li>';

return $items;
}

I need to change the code so it only applies to my secondary menu that is registered like so.

function register_main_menus() {
	register_nav_menus(
		array(
			'primary-menu' => __( 'Primary Menu' ),
			'secondary-menu' => __( 'Second Menu' )
		)
	);
}

How can I apply this login/logout code to just the Secondary Menu?

Part 2…
I’d also like to be able to select the order it is placed in. Right now I need it added to the end of the menu items.

Thanks
