How to get title from WP_Post Object
This is from my notes that I got working with your exact situation. Hope it helps.
<?php $my_wp_query = new WP_Query(); $all_wp_pages = $my_wp_query->query(array('post_type' => 'page', 'posts_per_page' => -1)); $childpg = get_page_children(8, $all_wp_pages); foreach($childpg as $children){ $page = $children->ID; $page_data = get_page($page); $content = $page_data->post_content; $content = $page_data->the_title; $content = apply_filters('the_content',$content); $content = str_replace(']]>', ']]>', $content); echo '<div class="row-fluid"><span class="span4">'; echo get_the_post_thumbnail( $page ); echo '</span><span class="span8">'.$content.'</span></div>'; } ?>
