WordPress Show Related Posts

It’s nice to be able to show your related posts – and without a plugin it’s even better.

 
<?php 
$tags = wp_get_post_tags($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'=>1,
'caller_get_posts'=>1 
); 
$my_query = new WP_Query($args); 
 
if( $my_query->have_posts() ) { 
 
while ($my_query->have_posts()) : $my_query->the_post(); ?> 
<p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p> 
<?php 
 
endwhile; wp_reset(); 
} 
} 
?>
