‘Related Posts’ hacking in wordpress

When i noticed my blog andol.info lacking some popular functions like ‘related posts’, i decided to do it myself. I googled the ‘related posts’ but most of present results are about installing plugins, no code level tips are provided. I dont like using plugins in wordpress bacause huge number of plugins probably slow down the browsing speed. 

So i just hacked it myself: adding the 2nd post query-> matching the query conditions->get result & display & CSS. Some codes are shared below.

<div id=’rltpost’>

<?php

  if(get_the_category()) {

    echo”<p><strong>&nbsp;Posts may be of interest to you:</strong></p><ul>”;

    foreach((get_the_category()) as $category) {

      $query2 = new WP_Query(“cat=”.$category->cat_ID.”&showposts=3&orderby=rand”);

      while($query2->have_posts()):

      $query2->the_post();

?>

      <li><a href=”<?php the_permalink() ?>” title=”permalink to: <?php the_title() ?>”><?php the_title() ?></a></li>

<?php

      endwhile;

    }

    echo”</ul>”;

  }

?>

</div>

Instruction: just copy all the codes above to where you wanna show your ‘related posts’ section, and add the CSS style in current theme’s style.css file, done, enjoy.
