Here's the solution that @bainternet has posted here: Add child pages automatically to nav menu
/**
* auto_child_page_menu
*
* class to add top level page menu items all child pages on the fly

*/
class auto_child_page_menu
{
/**
* class constructor
* @author Ohad Raz <[email protected]>
* @param array $args
* @return void
*/
function __construct($args = array()){
add_filter('wp_nav_menu_objects',array($this,'on_the_fly'));
}
/**
* the magic function that adds the child pages
* @author Ohad Raz <[email protected]>
* @param array $items
* @return array
*/
function on_the_fly($items) {
global $post;
$tmp = array();
foreach ($items as $key => $i) {
$tmp[] = $i;
//if not page move on
if ($i->object != 'page'){
continue;
}
$page = get_post($i->object_id);
//if not parent page move on
if (!isset($page->post_parent) || $page->post_parent != 0) {
continue;
}
$children = get_pages( array('child_of' => $i->object_id) );
foreach ((array)$children as $c) {
//set parent menu
$c->menu_item_parent = $i->ID;
$c->object_id = $c->ID;
$c->object = 'page';
$c->type = 'post_type';
$c->type_label = 'Page';
$c->url = get_permalink( $c->ID);
$c->title = $c->post_title;
$c->target = '';
$c->attr_title = '';
$c->description = '';
$c->classes = array('','menu-item','menu-item-type-post_type','menu-item-object-page');
$c->xfn = '';
$c->current = ($post->ID == $c->ID)? true: false;
$c->current_item_ancestor = ($post->ID == $c->post_parent)? true: false; //probbably not right
$c->current_item_parent = ($post->ID == $c->post_parent)? true: false;
$tmp[] = $c;
}
}
return $tmp;
}
}
new auto_child_page_menu();
How to use it?
I have to implement it on a published website so I'm not in a position to experiment much...
c/p code to functions.php?
call the function from inside the header?
