I just created a conditional function for WordPress to check, if the current page has a parent page (or if the page is a sub page). It works outside the main loop, and also inside. To use this function, you need WordPress 2.5 or higher.


Download function

Example usage

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?>

<?php if ( has_parentpage() ): ?>
<p> This page has a parent page. </p>
<?php endif ?>

<?php endwhile; ?>
