Show Related Posts Using PHP

It is possible to add the “Related Posts” output directly into your site’s PHP files.

The best approach is to use the PHP to include the shortcode inside a PHP snippet, as in this example below.

<?php echo do_shortcode("[taxopress_relatedposts id="1"]"); ?>

Legacy PHP Code

There is also a legacy option allows you to make choices directly in the PHP code. This is the basic code snippet:

<?php st_related_posts(); ?>

Here are examples of how you can customize that basic code with more details:

'number' => 5,
'order' => 'count-desc',
'format' => 'list',
'include_page' => 'true',
'exclude_posts' => '',
'exclude_tags' => '',
'post_id' => '',
'except_wrap' => '55',
'limit_days' => '0',
'title' => __('<h4>Related posts</h4>', 'simpletags'),
'nopoststext' => __('No related posts.', 'simpletags'),
'dateformat' => $this->dateformat,
'xformat' => __('<a href="%post_permalink%" title="%post_title% (%post_date%)">%post_title%</a> (%post_comment%)', 'simpletags')

Here is an example of that legacy code in use. We want to show the first 10 related post without title, without pages and without comments count.

<?php st_related_posts('number=10&title=&include_page=false&xformat=<a href="%permalink%" title="%title% (%date%)">%title%</a>'); ?>
