I have built a little script that indicates if one specific element should be taken from a cache instead of a query.

I started with an action triggered after each post update like this:

function post_cache($post_ID)

function my_other_function($variable)
  echo $variable;

Each time a post is updated the my_other_function is triggered correctly and works as expected. Now if I add the same for menu updates, it does not only fire for menu updates but it also fires for every existing page.

function menu_cache($any_variable)

When I save the menu, this function is fired but post_cache is also fired for all posts available. I don't understand why it happens because there is no link between menu_cache and post_cache.

I have done the same for comments update and it also works as expected. It's only when I use wp_update_nav_menu that post_cache is also called.

Thanks Laurent

    At first you are missing the second mandatory argument for defining a function in your add_action() call. This may resolves the issue. Not sure… It should be add_action('wp_update_nav_menu', 'menu_cache');. Note: You can omit the 3rd and 4th parameter as 10 and 1 are the default values. – Fabian Marz Sep 18 '18 at 23:48
  • Hello Fabian, that actually solved the issue, thanks! – user3638239 Sep 22 '18 at 10:22

The solution was given by Fabian Marz. I remove the default parameters and added one variable in the function call.
