   Hey Guys,
   I'm using a meta box to store a bunch of page ID. When I try to pass the page ID's to the post__in parameter of WP_Query it only seems to take the first ID, not all of them.

   So, say the "relatedpages" meta box contains: 55, 33, 22

   $relatedpages = get_post_meta($post->ID, 'relatedpages', true);
   
   $args = array(
   	'post_type' 		=> 'page',
   	'posts_per_page' 	=> -1,
   	'order'			=> 'ASC',
   	'orderby' 		=> 'menu_order',
   	'post__in' 		=> array($relatedpages)
   	);
   
   $myposts = get_posts($args);
   echo $myposts;

   If you do that, you'll only get one post. Where as if you replace 'array($relatedpages)' with 'array(55, 33, 22)' you'll get all 3 posts.

   Is it something I'm doing wrong with my PHP syntax?

   Thanks,
   Drew

   So I figured out that the problem is that $relatedpages is a string, and it needs to be a comma separated integers.

   Any ideas on how to over come this?

   Thanks!

   try and use the php function explode()
   http://php.net/manual/en/function.explode.php

   from:
   $relatedpages = get_post_meta($post->ID, 'relatedpages', true);
   to:
   

   $relatedpages = get_post_meta($post->ID, 'relatedpages', true);
   $relatedpages = explode(',', $relatedpages);

   and, from:
   'post__in' => array($relatedpages)
   to:
   'post__in' => $relatedpages

   (untested)

   Hey alchymyth,
   Thanks for the help, but in the end I think the problem was the 'post__in' parameter can't be used in get_posts like I wanted. Strange enough, the old 'include' does. So this worked!

   $args = array(
   	'post_type' 			=> 'page',
   	'posts_per_page' 		=> -1,
   	'order'				=> 'ASC',
   	'orderby' 			=> 'menu_order',
   	'include' 			=> $relatedpages
   	);
   
   $myposts = get_posts($args);

   Thanks anyway!
