This how I modify it to accept Custom Post Type (for example : video):
single.php :
related_posts('video');
related-functions.php :
> line 7
function related_posts($posttype = 'post', $a = array(),$echo=true,$reference_ID=false) {
return yarpp_related(array($posttype),$a,$echo,$reference_ID);
}
magic.php :
> line 283 (maybe the number of the lines are wrong)
// get the related posts from postdata, and also construct the relate_IDs array
$yarpp_related_postdata = get_post_meta($reference_ID,YARPP_POSTMETA_RELATED_KEY,true);
– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –
Here we have to modify how it get the related ID (of posts).
This is how it works :
1) yarpp.php
// update cache on save
add_action(‘save_post’,’yarpp_save_cache’);
->
2) magic.php
function yarpp_save_cache($post_ID,$force=true)
if (yarpp_get_option('cross_relate'))
$type = array('post','page');
elseif ($post_type == 'page')
$type = array('page');
elseif ($post_type == 'video')
$type = array('video');
else
$type = array('post');
3) magic.php
function yarpp_cache_enforce($type=array(‘post’),$reference_ID,$force=false)
->
$related = $wpdb->get_results(yarpp_sql($type,array(),true,$reference_ID), ARRAY_A);
4) magic.php
function yarpp_sql($type,$args,$giveresults = true,$reference_ID=false,$domain=’website’)
if ($type == array('page') && !$cross_relate)
$newsql .= " and post_type = 'page'";
elseif ($type == array('video'))
$newsql .= " and post_type = 'video'";
else
$newsql .= " and post_type = 'post'";
You can improve the script trying to accept multiple Custom Post Type :
related_posts(array(‘video’,’portfolio’,’gallery’));
