I've modified _wp_menu_item_classes_by_context in order to handle some special URL properly with menu.
Testing with a default install and URL rewritting + parameters GET/POST was a fail.
So now that I've hacked, I'd like to "filter" this custom function with my_wp_menu_item_classes_by_context
I do not really from where to go since the private function pass a pointer to the $menu and not the menu itself, so basically it return nothing...
I've tried :
add_filter('_wp_menu_item_classes_by_context', 'my_wp_menu_item_classes_by_context', 1, 2);
But it gives nothing, giving that my_wp_menu_item_classes_by_context is the new function...
Thank you !
