Here is a section of code that I have in a template file — to display sub-navigation if the page has child-pages:
<?php // display sub-nav if page has children ?> <?php $children = get_pages(array('child_of' => $post->ID)); ?> <?php if (count($children)) : ?> <ul class="nav nav-tabs"> <?php foreach ($children as $val) : ?> <li role="presentation"> <a href="<?php echo get_permalink($val->ID); ?>"><?php echo $val->post_title; ?></a> </li> <?php endforeach; ?> </ul>
The code works fine when in the template file
page.php, but if I put it all into a new file —
nav.php and then include it with
<?php get_template_part( 'include', 'nav' ); ?> then it stops working.
How can I set it so that the
$post variable still works? Do I need to do something with global variables?
