Display child pages in sidebar of parent page in wordpress

Question

How to get displayed child pages on parent page and also on child page of that parent in sidebar?Trying to paste code from wp codex page and from several other sites, but with no success.I always get instead of list of child pages, list of parent pages!? what is the problem?Just to mention, maybe is important, all parent pages have its own page-template.

example code:

    <?php
    if($post->post_parent)
    $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0"); else
    $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
   if ($children) { ?>
<ul>
<?php echo $children; ?>
</ul>
<?php } ?>

I also try this code which seems to me doing god job, but again I got list of parent pages

Answer 1

If you don't want a list of Pages, then why are you calling wp_list_pages() in your code? that function returns a list of Pages.

You probably need to use get_posts() instead, and then loop through the results to output whatever $post content you want to display.

e.g. you could do something like the following:

<?php
global $post;
$child_pages = get_posts( array(
    'post_parent' => $post->ID
) );
?>
<ul>
<?php
foreach ( $child_pages as $child ) {
    ?>
    <li>
        <h3><?php echo $child->post_title; ?></h3>
        <div><?php echo $child->post_content; ?></div>
    </li>
    <?php
}
?>
</ul>

EDIT

If you need to access $post->ID from outside the Loop, do something like this inside the Loop:

$current_post_id = $post->post_ID;

Then, just use $current_post_id outside the Loop. (Note that you'll only want to do this on template pages that display single Posts; otherwise, the value of $current_post_id will change on every cycle of the foreach loop.)

You could then change your get_posts() call accordingly:

$child_pages = get_posts( array(
    'post_parent' => $current_post_id
) );

This is the solution I am using

<?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=". $parent ."&echo=0");
    if ($children) { ?>
    <ul class="tabs vertical hide-on-phones three columns">
        <li>Hekki</li>
        <?php echo $children; ?>
    </ul>
<?php } ?>

I want the parent page to display as well.

This worked for me: notice the use of depth in the child wp_list_pages.

<?php 
    if($post->post_parent)
        $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
    else
        $children = wp_list_pages("title_li=&depth=1&child_of=".$post->ID."&echo=0");
    if ($children) { ?>

   <ul>
        <?php echo $children; ?>
    </ul>
<?php } ?>

Try this

    <ul class="sidenav">
    <?php
    if($post->post_parent)
        $children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0");
    else
        $children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
    if ($children) { ?>
    <ul>
        <?php echo $children; ?>
    </ul>
    <?php } ?>          
    </ul>
