获取当前页面的子页面以及当前页面链接

Question

I intend to create a sidebar to retrieve a list of the current page's children as well as the current page itself. Here is the code that I have been using which retrieves the current pages children even when on the child pages, however when I try to include the $parent as $post->post_parent it displays all pages

    <?php
   if ($post->post_parent)  {
        $ancestors=get_post_ancestors($post->ID);
        $root=count($ancestors)-1;
        $parent = $ancestors[$root];
    } else {
        $parent = $post->ID;
    }
    $children = wp_list_pages("title_li=&child_of=". $parent ."&echo=0");
    $parent = wp_list_pages("title_li=&child_of=". $post->post_parent ."&echo=0");
    if ($children) { ?>
    <ul class="tabs">
        <?php echo  $parent ?>
        <?php echo $children; ?>
    </ul>
<?php } ?>

/*-------------------------------------------------------------------
    Return parent page ID or child as else. Add this to functions.php
---------------------------------------------------------------------*/

function get_top_parent_page_id() { 
    global $post; 

    if ($post->ancestors) { 
        return end($post->ancestors); 
    } else { 
        return $post->ID; 
    } 
}

//Use this in the template

<?php while ( have_posts() ) : the_post(); 

    //Add parent page slug into arguments
    $query = new WP_Query('pagename=page_slug');
    if ($query->have_posts() ){ while ($query->have_posts() ) { $query->the_post(); } }

    //Get children by calling function in functions.php for the top parent id                  
    $current_page_id = get_top_parent_page_id();
    $args = array( 'post_type' => 'safaris', 'post_parent' => $current_page_id, 'orderby' => 'title', 'order' => 'ASC' );
    $child_query = new WP_Query($args);

    $i = 0; 
    if ($child_query->have_posts() ){ while ($child_query->have_posts() ){ $child_query->the_post(); 
    $i++; if( 1 == $i ) { ?>

    <li role="presentation" class="active"><?php the_title(); ?></li>

    <?php } else { ?>

    <li role="presentation"><?php the_title(); ?></li>

    <?php } } } wp_reset_postdata();  endwhile; ?>
