Thanks for the reply, this worked perfectly for the shortcode. Thanks you!
I’m wondering why I can’t get your other code to work using the same fix?
I’d love to avoid using the plugin so I can more easily customize the markup of the related posts.
To jog the memory, here’s the code I’ve placed in my functions:
function get_related_tag_posts_ids( $post_id, $number = 5 ) {
$related_ids = false;
$post_ids = array();
// get tag ids belonging to $post_id
$tag_ids = wp_get_post_tags( $post_id, array( 'fields' => 'ids' ) );
if ( $tag_ids ) {
// get all posts that have the same tags
$tag_posts = get_posts(
array(
'posts_per_page' => -1, // return all posts
'no_found_rows' => true, // no need for pagination
'fields' => 'ids', // only return ids
'post__not_in' => array( $post_id ), // exclude $post_id from results
'tax_query' => array(
array(
'taxonomy' => 'post_tag',
'field' => 'id',
'terms' => $tag_ids,
'operator' => 'IN'
)
)
)
);
// loop through posts with the same tags
if ( $tag_posts ) {
$score = array();
$i = 0;
foreach ( $tag_posts as $tag_post ) {
// get tags for related post
$terms = wp_get_post_tags( $tag_post, array( 'fields' => 'ids' ) );
$total_score = 0;
foreach ( $terms as $term ) {
if ( in_array( $term, $tag_ids ) ) {
++$total_score;
}
}
if ( $total_score > 0 ) {
$score[$i]['ID'] = $tag_post;
// add number $i for sorting
$score[$i]['score'] = array( $total_score, $i );
}
++$i;
}
// sort the related posts from high score to low score
uasort( $score, 'sort_tag_score' );
// get sorted related post ids
$related_ids = wp_list_pluck( $score, 'ID' );
// limit ids
$related_ids = array_slice( $related_ids, 0, (int) $number );
}
}
return $related_ids;
}
function sort_tag_score( $item1, $item2 ) {
if ( $item1['score'][0] != $item2['score'][0] ) {
return $item1['score'][0] < $item2['score'][0] ? 1 : -1;
} else {
return $item1['score'][1] < $item2['score'][1] ? -1 : 1; // ASC
}
}
I’ve tried adding ‘post_type’ => ‘video’ to the $tag_posts = get_posts array, but if I use anything aside from ‘post’ it doesn’t return any results.
I also tried it the way you have in the shortcode, with ‘post_types’ => ‘video’ but still no dice.
Thanks again for any help
