 * I’m using this query on a custom page
 *     ```
       <?php
       $args = array(
         'post_type' => 'page',
         'post__in' => array(get_post_meta($post->ID, "page_id", true))
         );
       query_posts($args);
       ?>
       ```
   
 * So I’m adding the page ids I want to call in a custom field called “page_id”
 * So for example in that field I have 220,221,222 but only the first page is getting
   called.
 * Any ideas?

 * Try just using `get_post_meta($post->ID, "page_id")`

 * Umm, I tried this instead
 *     ```
       <?php
       $args = array(
         'post_type' => 'page',
         'post__in' => get_post_meta($post->ID, "page_id")
         );
       query_posts($args);
       ?>
       ```
   
 * But still only one page displays.
 * I then tried
 *     ```
       <?php
       $args = array(
         'post_type' => 'page',
         'post__in' => array(get_post_meta($post->ID, "page_id", false))
         );
       query_posts($args);
       ?>
       ```
   
 * and nothing displays.
 * I tried this, just to make sure it was working when not using the custom field
   value
 *     ```
       <?php
       $args = array(
         'post_type' => 'page',
         'post__in' => array(361,363)
         );
       query_posts($args);
       ?>
       ```
   
 * and it displays okay

 * this is because your custom field, and therefore the `$not_pages` variable, contains
   a single string of comma-separated numbers – not an array;
 * try to use the php function `explode()` to turn that into an array:

 * Blimey! Thanks for that but I have got absolutely zero idea where to start with
   exploding stuff.

 * did you try to read and apply the linked tutorial?
 * based on you last posted code section:
 *     ```
       $not_pages = explode(',',get_post_meta($post->ID, "page_id"));
       ```

 * Thanks again. I just realised that I asked a similar question on here over 2 
   years ago but I can’t for the life of me get this to work in a query posts function
 *     ```
       <ul>
        <?php
       $key = get_post_meta($post->ID, 'page_id', true);
       $key = explode(',', $key);
       function trim_value(&$value)
       {
           $value = (int)trim($value);
       }
       array_walk($key, 'trim_value');
       $myposts = get_posts(array('post__in' => $key, 'posts_per_page' => -1));
       foreach($myposts as $post) :
          setup_postdata($post);
        ?>
           <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
        <?php endforeach; ?>
        </ul>
       ```
   
 * I’d like the above code to work in this format:
 *     ```
       <?php
       // My query here
       ?>
       <?php while (have_posts()) : the_post(); ?>
       <p><?php the_title() ?></p>
       <?php endwhile;?>
       ```

 * I managed to get this to work…

       <?php
       $key = get_post_meta($post->ID, 'page_id', true);
       $key = explode(',', $key);
       function trim_value($value)
       {
           $value = (int)trim($value);
       }
       array_walk($key, 'trim_value');
        $myposts = get_posts(array('post_type' => 'page', 'post__in' => $key, 'showposts' => -1, 'orderby'=> date, 'order'=> DESC));
        foreach($myposts as $post) :
          setup_postdata($post);
        ?>
       <h2><?php the_title() ?></h2>
        <?php endforeach; ?>
       ```
