List taxonomy / category count showing list published posts only

Question

I want to show on a list of taxonomy with corresponding posts counts of published items only. Checking the WP documentation, It seems I can ALMOST achieve that by using the get_terms function https://developer.wordpress.org/reference/functions/get_terms/ but I get ALL the posts counts including draft and trashed.

$taxonomy = 'item_category';
  $args =  array(
    'hide_empty' => false,
    'orderby'    => 'name',
    'order'      => 'ASC'
  );
$terms = get_terms( $taxonomy , $args );

foreach( $terms as $term ) {
  echo $term->name . ' - ' . $term->count . '<br/>';
}

Does WP have a built in args to display it from the get_terms function because I don't see it under the documentation? Is there any other functions or filter that I can try to achieve my desired output?

Answer 1

Checked the source, and it seems the only way to get this done is filtering the output count for each term, you can achieve that by inserting this filter before your get_terms call. Note that this will now always display published item count so be careful on its usage.

function get_terms_filter_published( $terms, $taxonomies, $args ) {
  global $wpdb;
  $taxonomy = $taxonomies[0];
  if ( ! is_array($terms) && count($terms) < 1 ) {
    return $terms;
  }

  $filtered_terms = array();
  $ctr = 0;
  foreach ( $terms as $term ) {
    $result = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts p JOIN $wpdb->term_relationships rl ON p.ID = rl.object_id WHERE rl.term_taxonomy_id = $term->term_id AND p.post_status = 'publish' LIMIT 1");
    $published_terms[ $ctr ] = $term;
    if ( intval($result) > 0 ) {
        $published_terms[ $ctr ] = $term;
    } else {
        // you can comment this out if you don't want to show empty terms
        $published_terms[ $ctr ]->count = 0;
    }
    $ctr++;
  }
  return $published_terms;
}

add_filter('get_terms', 'get_terms_filter_published', 10, 3);

$taxonomy = 'item_category';
$args =  array(
  'hide_empty' => false,
  'orderby'    => 'name',
  'order'      => 'ASC'
);
$terms = get_terms( $taxonomy , $args );

foreach( $terms as $term ) {
  echo $term->name . ' - ' . $term->count . '<br/>';
}
