When I changed my WordPress theme from Thesis to Genesis, I had to make some major changes to my website. This included customising code that performs certain functions so it would work for me in a Genesis 2.0 website that had new hooks and HTML5.

One of the customisations I needed was to manually add in simple related posts at the bottom of each single post. I did not want thumbnail images, just simple text.

I ran into a few problems:

1. The code snippets I had were for Thesis or other WordPress themes.
2. Any related posts code had a thumbnail image included. I wanted text only.
3. Genesis 2 had new hooks so the tutorials they had did not help at all.
4. I needed css to match my new theme.

Here is a screenshot of what my related posts looks like now. Of course I sorted out the problems.

So if you have the new Genesis 2 and you have a html5 child theme then this tutorial is for you. If you have the old Genesis then you will need to edit the Genesis hooks I used. (genesis_entry_footer)

Original code here.

/** Display related posts in Genesis */
function related_posts_tags () {
if ( is_single ( ) ) {
global $post;
$count = 0;
$postIDs = array( $post->ID );
$related = '';
$tags = wp_get_post_tags( $post->ID );
foreach ( $tags as $tag ) {
$tagID[] = $tag->term_id;
}
$args = array(
'tag__in'               => $tagID,
'post__not_in'          => $postIDs,
'showposts'             => 5,
'ignore_sticky_posts'   => 1,
'tax_query'             => array(
array(
'taxonomy'  => 'post_format',
'field'     => 'slug',
'terms'     => array(
'post-format-link',
'post-format-status',
'post-format-aside',
'post-format-quote'
),
'operator'  => 'NOT IN'
)
)
);
$tag_query = new WP_Query( $args );
if ( $tag_query->have_posts() ) {
while ( $tag_query->have_posts() ) {
$tag_query->the_post();
$related .= '<li><a href="' . get_permalink() . '" rel="bookmark" title="Permanent Link to' . get_the_title() . '">' . get_the_title() . '</a></li>';
$postIDs[] = $post->ID;
$count++;
}
}
if ( $related ) {
printf( '<div><h3>Related Posts</h3><ul>%s</ul></div>', $related );
}
wp_reset_query();
}
}
add_action( 'genesis_entry_footer', 'related_posts_tags' );


Where is the functions.php file and where do I put the code?
