How to show related posts with Perch blog

related-posts.php

<?php
      $categories = perch_blog_post_categories(perch_get('s'), array(
          'skip-template'=>true, 
          ));

          if (count($categories)) {
            $cat_slugs = array();
            foreach($categories as $cat) {
            $cat_slugs[] = $cat['catSlug'];
            }

      perch_blog_custom(array(
            'filter' => 'postSlug',
             'match' => 'neq',
             'value' => perch_get('s'),
             'category' => $cat_slugs,
             'sort' => 'postDateTime',
             'sort-order'=> 'DESC',
             'count'=> 2,
             'template'=> 'blog/post_in_list_related.html',
          ));
        } 
  ?>

This is how I display related posts with Perch CMS.

See this post for a more detailed explanation.
