 * Hi,
 * I need to fix a nested loop: first of all i’m getting all posts and in the loop
   of posts i’m getting al attachments (images) twice but in a different order.
 * The problem is it only works on the first item and not on the second. How do 
   i fixed this properly?
 *     ```
       <div class="content">
           <?php
           $args = array('posts_per_page' => 5, 'offset' => 0);
           $projectCount = 0;
           $myposts = get_posts($args);
           foreach ($myposts as $post) : setup_postdata($post);
           $projectCount++;
               ?>
               <section class="project" id="<?php echo $projectCount ?>">
                   <h2><?php the_title(); ?></h2><p><strong><?php echo wp_strip_all_tags(preg_replace('/<img[^>]+./', '', $post->post_content)); ?></strong></p>
                   <div class="colHolder">
                   <?php
                   $media = get_posts(array(
                       'post_parent' => $post->ID,
                       'post_type' => 'attachment',
                       'post_mime_type' => 'image',
                       'orderby' => 'title',
                       'order' => 'ASC'
                   ));
                   //print_r($media);
                   ?>
                   <?php foreach($media as $key => $image): ?>
                       <?php if(!empty($image->post_title)): ?>

                       ));
                       //
                       foreach($allmedia as $key => $imagel):

 * You mean the second `get_posts()` for attachments is not working, right?
 * Probably because ‘caption’ is not a valid ‘orderby’ argument. Unlike in SQL where
   you can use any column name, there is a limited set of orderby arguments for `
   get_posts()`.
    [https://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters](https://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters)
 * `get_posts()` uses WP_Query, so any valid WP_Query argument will work in `get_posts()`.
 * Attachments store captions in ‘post_excerpt’, but that’s not a valid orderby 
   argument either. What you can do is alter the SQL query generated by `get_posts()`
   through the ‘posts_request’ filter. Add your filter callback just before calling
   the second attachment `get_posts()`, then remove it immediately afterwards so
   the callback does not alter any other post queries.
