Include specific pages in query and sort by order in menu

    I’m working on a single scroll site. I want to include ONLY pages which appear in the primary menu of the site. If a page is not in the primary menu, it should NOT be included in the loop. I also want the order of pages output by the query to be in the same order which they are in the menu. Here is what I have so far:

    $page_sort_sections = sort_sections();

			$args = array(
				'posts_per_page' => -1,
				'post_type' => 'page',
				'post__in'  => (array) $page_sort_sections,
				'orderby' => 'post__in',
				);

			$home_query = new WP_Query($args);  

			if($home_query->have_posts()):  while($home_query->have_posts()) : $home_query->the_post();

				get_template_part('page-sections');

				endwhile;

			else:

				get_template_part( '404');

			endif;

    That takes care of setting up the query.

    Here is the code of the function which I am using to pass in the post__in array:

    if ( ! function_exists( 'sort_sections' ) ){

	function sort_sections(){

		if(!has_nav_menu( 'primary' )){
			return;
		}

		if ( ( $locations = get_nav_menu_locations() ) && isset( $locations['primary'] ) ) {

			$menu = wp_get_nav_menu_object( $locations['primary'] );

			$items  = wp_get_nav_menu_items($menu->term_id);

			$sections = array();

			foreach((array) $items as $key => $menu_items){

				if('page-sections' == $menu_items->object){

					$sections[] = $menu_items->object_id;
				}

			}

			return $sections;

		}

	}

}

    I did a var_dump on the query and its returning:

    ["post__in"]=>
    array(0) {
    }
    ["orderby"]=>
    string(8) "post__in"
  }

    Any thoughts on why this not returning the IDs of the items in the menu?

    Thanks 🙂

    I wanted to thank you for pointing me in the right direction and provide the code that is currently working for me. (wp 3.7.1)
    -in functions.php:

    // Menu item IDs
function grab_menu_items(){
		$menu_name = 'primary';

    	if ( ( $locations = get_nav_menu_locations() ) && isset( $locations[ $menu_name ] ) ) {
		$menu = wp_get_nav_menu_object( $locations[ $menu_name ] );
		$menu_items = wp_get_nav_menu_items($menu->term_id);
		$theidlist = array();
			foreach ( (array) $menu_items as $key => $menu_item ) {
				$theidlist[] = $menu_item->object_id;
			}
		return $theidlist;
		} else { return; }
}

    -and the query:

    $menuitems = grab_menu_items();
    /* Query */
	$the_query = new WP_Query( array( 'post_type' => 'page', 'orderby' => 'post__in', 'posts_per_page' => '-1', 'post__in' => $menuitems ) );
    /* The Loop */
    while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
   		<div id="box<?php the_ID(); ?>" class="shadow-box"><?php the_excerpt(); ?><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>" rel="bookmark">read more</a></div>
    <?php endwhile; /* Restore original Post Data */ wp_reset_query();
