Get permalink to first child page

    I’m using one template for the front of several exhibits. From these pages I need to link directly to the first child of each exhibit, using a “Start Here” link.

    I’ve found a couple solutions to this, but none have worked, such as this one on stackoverflow:

    <?php
    if ($children = get_children('post_type=page&numberposts=1')) {
        $first_child = $children[0];
        $first_child_permalink = get_permalink($first_child->ID);
        echo '<a href="' . $first_child_permalink . '">Start Here</a>';
    }
?>

    It looks right. What’s wrong? Any other ideas?

    I’ve got part of it working. The array was written incorrectly. $children var_dumps the correct page. Now I am having trouble getting that page’s url.

    $page_id = get_the_ID();
$children = get_children(array(
	'post_type'   => 'page',
	'post_parent' => $page_id,
	'numberposts' => 1
	));
$first_child = $children[0];
$first_child_permalink = get_permalink($first_child->ID);
  echo '<a href ="' . $first_child_permalink . '">Start here</a>';

    I can’t understand why $children[0] is returning null. The variable is not empty. This is the beginning of it…

    array(1) { [582]=> object(WP_Post)#124 (24) { [“ID”]=> int(582) [“post_author”]=> string(1) “1” [“post_date”]=> string(19) “2014-05-06 10:34:17” [“post_date_gmt”]=> string(19) “2014-05-06 14:34:17” [“post_content”]=> string(676) …

    How can I grab that first element in the array?

    I see. [582] in the above array is not the first element. It is the 582nd element.

    GOT IT!

    Instead of using get_children I used get_pages. (Thanks to James Fishwick!)

    $children = get_pages("child_of=".$post->ID."&sort_column=menu_order");
$first_child = $children[0];
$first_child_permalink = get_permalink($first_child->ID);
echo '<a href="' . $first_child_permalink . '">Start Here</a>';
