Check for grandchildren menu?

[Duplicated threads will be deleted]

Hey everyone,

What am I missing? I created a menu of grandchildren pages, and I want it to appear only if the section has grandchildren pages, of course.

There’s something wrong with the code obviously – as it also shows up when there are only children pages too.

This is the code for both the children menu & the grandchildren menu:

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

if ($children && is_page()) { ?>
<ul id="subnav">
<?php echo $children; ?>
</ul>
<?php } else { ?>
<?php } ?> 

<ul id="grandnav">
<?php
$grandchildren = wp_list_pages("title_li=&child_of=&child_of=".$post->ID."&echo=0depth=2");
if ($grandchildren && is_page()) { ?>
<?php echo $grandchildren; ?>
<?php } else { ?>
<?php } ?>
</ul>

Thanks in advance!
