How To Display Related Post In Carrington Mobile Theme Without Plugin

I recently put up a guide on how you can install and use the carrington mobile theme for your wordpress blog, and I got a Facebook private message from someone requesting how he can easily customize and add up a related post widget to the mobile friendly design.

Just like any other wordpress theme, the file in charge of displaying posts in the Carrington theme is the single.php file and that’s where we would be adding the WP query that would output the related post widget.

Note: The related post we would be adding here is based on wordpress tags, meaning it relates articles you added tags to. If you don’t make use of the tags while posting in wordpress, this would not work for you.

Adding Related Post To Carrington Mobile

This would require you logging into your cPanel > File manager so as to edit the core single.php file of your carrington theme.

1. Login to cPanel > Filemanger then follow the path public_html/your site name/wp-content/themes/carrington-mobile-1.2 .

2. In this directory, you’ll see all the theme files, right click on the single.php file and click on Edit.

3. Once the page loads to edit, Search using CTRL + F for “cfct_content();” without the quotes and in the line after the code paste the below code.

 ?>
<?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(); ?>
<p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
<?php
endwhile;
}
}
?>
<?php


4. Then Click on Save at the top right corner of the screen.

As I said earlier in this post, it would only work on sites where the tags are made use of.
