<?php $child_pages = $wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_parent = " . $post->ID . " AND post_type = 'page' ORDER BY menu_order", 'OBJECT'); ?> <?php if ($child_pages):
foreach ($child_pages as $pageChild):
setup_postdata($pageChild); ?> <div class="child-thumb"> <?php echo get_the_post_thumbnail($pageChild->ID, 'thumbnail'); ?> <a href="<?php echo get_permalink($pageChild->ID); ?>" rel="bookmark" title="<?php echo $pageChild->post_title; ?>"><?php echo $pageChild->post_title; ?></a> </div> <?php
endforeach;
endif; ?>
This can be used as part of a for loop to list child pages inside of widget items like so:
foreach($products_slider as $post) : setup_postdata($post); ?> <div class="product_item"> <?php the_post_thumbnail(); ?> <div class="product_title"> <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3> <ul class="subproducts"> <?php $child_pages = $wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_parent = " . $post->ID . " AND post_type = 'page' ORDER BY menu_order", 'OBJECT'); ?> <?php if ($child_pages):
foreach ($child_pages as $pageChild):
setup_postdata($pageChild); ?> <?php //echo get_the_post_thumbnail($pageChild->ID, 'thumbnail');
?> <li><a href="<?php echo get_permalink($pageChild->ID); ?>" rel="bookmark" title="<?php echo $pageChild->post_title; ?>"><?php echo $pageChild->post_title; ?></a></li> <?php
endforeach;
endif; ?> </ul> </div> </div> <?php
endforeach;
wp_reset_postdata();
Sourced here To list child pages or same level pages, when on a child page, use this example from WordPress:
<?php if ($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
} ?>
The above example will list all subpages inclusively, including same level pages. To create a submenu that excludes parent pages, and lists child items in a drill down method, use the following:
<?php global $post;
if (is_page())
{
$page = $post->ID;
if ($post->post_parent)
{
$page = $post->post_parent;
}
$theparent = $ancestors[0];
$oneup = $ancestors[1];
$lastlevel = $ancestors[2];
$children = wp_list_pages('title_li=&echo=0&depth=1&child_of=' . $post->ID);
$sub = wp_list_pages('title_li=&echo=0&depth=1&child_of=' . $post->post_parent);
$twolevels = wp_list_pages('title_li=&echo=0&depth=0&child_of=' . $theparent);
if ($lastlevel)
{
echo $twolevels;
}
elseif ($children)
{
echo $children;
}
elseif ($sub)
{
echo $sub;
}
} ?>
