How to get the ID of Child Pages?

    I need some help to get the child id of a page. I am grabbing the content off the child page, and displaying the content in a text box on the parent page.

    I have achieved this previously by just sticking in the page ID’s in the code – but i want a dynamice way to do this.

    I searched the codex and found get_page_children, which I think returns what I need – I just don’t know how to get the page ID’s out of this?

    Here is what i have so far:

    $my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));
$current_page_ID = $post->ID;
$child_pages = get_page_children( $current_page_ID, $all_wp_pages ) 

//need to get the child page ID from $child_pages...then add in below
// echo getPageContent(ID_of_the_child_page);

    For the site I am creating I only have one child page, so i really am most interested in getting the ‘first’ child page ID.

    Can you help?

    Here is what I think you want. I added ‘posts_per_page’ to the query. Otherwise, you only get back the number set in Admin->Settings->Reading.

    I also assume that this is used in the Loop. Otherwise, $post->ID will be empty.

    $my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page', 'posts_per_page' => -1));
$current_page_ID = $post->ID;
$child_pages = get_page_children( $current_page_ID, $all_wp_pages ) 

// Get the ID from the first $child_pages entry
$child_id = $child_pages[0]->ID;
// echo getPageContent($child_id);

    Thanks vtxyzzy.
    This was what I was trying to do, and you way look like what i wanted! I eventually managed to get what I needed by doing this:

    $pages = get_pages('child_of='.$post->ID.'&sort_column=post_date&sort_order=desc');
$count = 0;
foreach($pages as $page)
{
echo getPageContent($page->ID);
}

    getPageContent is a function which returns the content of a page with formatting maintained:

    if(!function_exists('getPageContent'))
	{
		function getPageContent($pageId)
		{
			if(!is_numeric($pageId))
			{
				return;
			}
			global $wpdb;
			$sql_query = 'SELECT DISTINCT * FROM ' . $wpdb->posts .
			' WHERE ' . $wpdb->posts . '.ID=' . $pageId;
			$posts = $wpdb->get_results($sql_query);
			if(!empty($posts))
			{
				foreach($posts as $post)
				{
					return nl2br($post->post_content);
				}
			}
		}
	}
