marcelolz on "List Pages Sisters/Parents in Sidebar"

Hi!

How to add a list / menu in the sidebar to view the pages daughters and sisters of the current parent page?

The code below displays the correct list when it is inserted on the page, but the widget it lists all pages , not just of the current group . Is there a way to change it to also work on the side ? Or perhaps another solution ?

Thank you !

hook :

<?php
$submenu = hierarchical_submenu($post);
if ($submenu) {
    echo $submenu;
} else {
    // Do something else
}
?>

In Functions page:

function hierarchical_submenu($post) {
    $top_post = $post;
    // If the post has ancestors, get its ultimate parent and make that the top post
    if ($post->post_parent && $post->ancestors) {
        $top_post = get_post(end($post->ancestors));
    }
    // Always start traversing from the top of the tree
    return hierarchical_submenu_get_children($top_post, $post);
}

function hierarchical_submenu_get_children($post, $current_page) {
    $menu = '';
    // Get all immediate children of this page
    $children = get_pages('child_of=' . $post->ID . '&parent=' . $post->ID . '&sort_column=menu_order&sort_order=ASC');
    if ($children) {
        $menu = "\n<ul>\n";
        foreach ($children as $child) {
            // If the child is the viewed page or one of its ancestors, highlight it
            if (in_array($child->ID, get_post_ancestors($current_page)) || ($child->ID == $current_page->ID)) {
                $menu .= '<li class="sel"><a href="' . get_permalink($child) . '" class="sel"><strong>' . $child->post_title . '</strong></a>';
            } else {
                $menu .= '<li><a href="' . get_permalink($child) . '">' . $child->post_title . '</a>';
            }
            // If the page has children and is the viewed page or one of its ancestors, get its children
            if (get_children($child->ID) && (in_array($child->ID, get_post_ancestors($current_page)) || ($child->ID == $current_page->ID))) {
                $menu .= hierarchical_submenu_get_children($child, $current_page);
            }
            $menu .= "</li>\n";
        }
        $menu .= "</ul>\n";
    }
    return $menu;
}
