How to show related posts in wordpress without plugin

I have been talking about lots of wordpress plugin, and at the same time I suggest using minimum wordpress plugin to make your wordpress fast. We have already written a post on how you can add adsense code without any wodpress plugin

Some of the wordpress plugin which I have covered till now are

Add related post using Yet another related post plugin

Wordpress ALL in one SEO plugin : A complete review

Platinum SEO pack plugin : Alternative to ALL on one SEO plugin

Feed subscription reminder plugin

This is a simple code which will pull up related post. You can put this code either in your single.php file or on the sidebar using Samsarin php widget wordpress plugin

<?php
$tags = wp_get_post_tags($post->ID);
if ($tags) {
    $tag_ids = array();
    foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;

    $args=array(
        'tag__in' => $tag_ids,
        'post__not_in' => array($post->ID),
        'showposts'=>5, // Number of related posts that will be shown.
        'caller_get_posts'=>1
    );
    $my_query = new wp_query($args);
    if( $my_query->have_posts() ) {
        echo '<h3>Related Posts</h3><ul>';
        while ($my_query->have_posts()) {
            $my_query->the_post();
        ?>
            <li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></li>
        <?php
        }
        echo '</ul>';
    }
}
?>

This code pull of related post using the tag feature.

Try to avoid plugins as much as you can , and use custom wordpress code and hacks to pull up any query.
