WpRecipes.com - Daily recipes to cook with WordPress

In order to achieve this recipe, place the following code on your sidebar.php file.

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

The above code executes the wp_list_pages function, with the echo=0 parameter, which allow us to get the result of the function without displaying it. Then, we test if the $children variable isn't empty, and we display our children pages.
