Integrate "Microkid´s Related Posts" with Arlima

Here's an example of how to integrate MRP with Arlima.

functions.php

/**
 * Get an array with related posts that can be used in Arlima's article templates.
 * @param bool|int $post_id - Optional
 * @return array|bool
 */
function get_related_posts( $post_id = false) {
    global $post;
    $data = false;
    if( $post_id || is_object($post) ) {
        if(!$post_id)
            $post_id = $post->ID;

        $related_posts = MRP_get_related_posts($post_id, true);
        if( !empty($related_posts) ) {
            $data = array('single' => count($related_posts) == 1, 'posts'=>array());
            foreach ( $related_posts as $related ) {
                $related->url = get_permalink ( $related->ID );
                $stats = wp_count_comments($post_id);
                if( is_object($stats) && !empty($stats->approved) )
                    $related->num_comments = $stats->approved;

                $data['posts'][] = $related;
            }
        }
    }

    return $data;
}

// Add checkbox that can be used by editors to control whether 
// or not related posts should be displayed in the article
add_action('arlima_list_manager_article_connection', function() { ?> 
   <label class="alignright">
     Hide related posts:
     <input type="checkbox" class="data hide-related" data-feature="hide_related" data-prop="options:hideRelated" />
   </label>
<?php });


// Make related posts available in the article template
add_filter('arlima_article_related_content', function($count, $article, $post) {
   if( !empty($post) && empty($article['options']['hideRelated']) ) 
      return get_related_posts($article['post']);
   return false;
}, 10, 3);
