The other day morvy posted an interesting piece of code for News Manager, that displays a list of similar/related posts (having tags in common):
$num_post = 5;
$slugs = array();
$url = nm_get_url('post');
$posts = nm_get_tags();
foreach($posts as $tag => $post) {
if(nm_post_has_tag($tag)) {
foreach ($post as $slug) {
$slugs[] = (string)$slug;
}
}
}
$slugs = array_unique($slugs);
if(($key = array_search(nm_post_slug(false), $slugs)) !== false) {
unset($slugs[$key]);
}
shuffle($slugs);
$slugs = array_slice($slugs, 0, $num_post);
$all = nm_get_posts();
echo '<ul class="nm_similar_post">';
foreach ($all as $post) {
if(in_array($post->slug, $slugs)) {
echo '<li><a href="'.$url.$post->slug.'" title="'.$post->title.'">'.$post->title.'</a></li>', PHP_EOL;
}
}
echo '</ul>';

A possible way to use it could be:
- paste the code into a new component, named e.g. nm-similar-posts
- enable Custom Settings and enter this below:
single componentBottomPost nm-similar-postsAnother way could be:
- paste the code into a new component, named e.g. nm-similar-posts
- insert this code somewhere in your template file -- you will probably need it after
<?php get_page_content(); ?>:
<?php if (nm_is_single()) { get_component('nm-similar-posts'); } ?>
