how avoid the link of the current post in the menu in the sidebar?

Question

When displaying in the sidebar the menu containing the list of posts, this menu also displays the link to the current post (the current page)

How avoid the link of the current post in this list of posts ?

The files actually used are wp-content/themes/mytheme/sidebar.php, wp-includes/nav-menu-template.php and wp-includes/nav-menu.php.

I use the Navigation Menu Widget.

Answer 1

you can try this code. the first filter is to customise the widget arguments and the second filter is in the menu generation.

add_filter("widget_nav_menu_args", function ($nav_menu_args, $nav_menu, $args, $widget_instance) {

    $post = get_queried_object();

    if (is_a($post, "WP_Post")) {
        $nav_menu_args["remove_post_in_widget"] = $post->ID;
    }


    return $nav_menu_args;

}, 10, 4);


add_filter("wp_nav_menu_objects", function ($sorted_menu_items, $args) {

    if (isset($args->remove_post_in_widget)) {

        foreach ($sorted_menu_items as $index => $item) {

            if ((int) $item->object_id === $args->remove_post_in_widget) {
                unset($sorted_menu_items[$index]);
                break; // stop the loop when the first post is found
            }

        }

    }


    return $sorted_menu_items;

}, 10, 2);
