 * Hi,
 * ‘post_parent’ => $post->ID returns a blank page, when using null it works, but
   that’s not what I want. I want to collect the attachments of its parent (or a
   specified post).
 * Does anybody know what’s the problem?
 *     ```
       <?php
       $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
       $wp_query = new WP_Query();
       $wp_query -> query('category_name=photo&posts_per_page=1&order=ASC&paged=' . $paged);
       ?>
   
       <?php while($wp_query -> have_posts()) : $wp_query -> the_post(); ?>
   
       <?php if(is_paged()){ ?>
   
       <?php
       $args = array(
       'post_type' => 'attachment',
       'numberposts' => 25,
       'post_parent' => $post->ID,
       'order' => 'ASC'
       );
   
       $attachments = get_posts($args);
       if($attachments){
       foreach($attachments as $attachment){
       $atturl = wp_get_attachment_thumb_url($attachment->ID);
       $attlink = get_attachment_link($attachment->ID) . '&paged=' . $paged;
       echo '<a href="' . $attlink . '"><img src="' . $atturl . '"></a>';
       }
       };
       ?>
   
       <?php } else { ?>
       <?php the_content(); ?>
       <?php }; ?>
   
       <?php endwhile; ?>
       ```

 * Can you rephrase?

 * Depending on your template, I see you are using quite a bit of globals, and you
   may need to appease that in your code.
 * Try at the top:
 * `global $wp_query, $post;`

 * Hey, thanks for the reply. Let me rephrase it.
 * In my code, when I use ‘null’ as value for argument ‘post_parent’, it shows all
   attachments (as thumbnails), so that works. But what I actually want is only 
   showing attachments from certain posts. The value ‘$post->ID’ should provide 
   me with the attachments of its parent, but it doesn’t work (no attachments show).
 * I also tried using global $wp_query, $post; but it didn’t solve it.

 * Why don’t you have a look at the method [get_children();](http://codex.wordpress.org/Function_Reference/get_children)
 * It might do what you are trying to do already.

 * Tried it, didn’t work! The problem remained.
 * It’s still the same as explained above. All attachments are shown when using ‘
   null’ as value for argument ‘post_parent’, but when using ‘$post->ID’ or argument‘
   include’ with as value a number of a specified post, it doesn’t work and shows
   nothing.
