Display Related Posts without using Plugins

Displaying related posts is a very great way to help visitors staying longer on your blog. You can use a plugin, but you also can use tags and a custom code to show related posts. Let’s see how to do!

This code will display related posts based on the current post tag(s). It must be pasted within the loop.

< ?php //for use in the loop, list 5 post titles related to first tag on //current post $tags = wp_get_post_tags($post->ID);

if ($tags) {

echo ‘Related Posts’;

$first_tag = $tags[0]->term_id;

$args=array(

‘tag__in’ => array($first_tag),

‘post__not_in’ => array($post->ID),

‘showposts’=>5,

‘caller_get_posts’=>1

);

$my_query = new WP_Query($args);

if( $my_query->have_posts() ) {

while ($my_query->have_posts()) : $my_query->the_post(); ?>
