Fixing category count

Question

Somehow my post counts are incorrect due to inserting rows via php. I have the following code to update the count, is it correct?

global $wpdb;
$result = mysql_query("SELECT term_id,term_taxonomy_id FROM $wpdb->term_taxonomy where taxonomy = 'category'");
while ($row = mysql_fetch_array($result)) {
  $term_taxonomy_id = $row['term_taxonomy_id'];      
  $countresult = mysql_query("SELECT object_id FROM $wpdb->term_relationships WHERE object_id IN (SELECT ID FROM $wpdb->posts WHERE post_type = 'post' AND post_status = 'publish') AND term_taxonomy_id = '$term_taxonomy_id'");
  $count = mysql_num_rows($countresult);
  mysql_query("UPDATE $wpdb->term_taxonomy SET count = '$count' WHERE term_taxonomy_id = '$term_taxonomy_id'");
        }

Answer 1

If you just want to update the counts of posts in each term, wp_update_term_count_now( $terms, $taxonomy ) should do it... just pass the terms affected as an array and run it once for each taxonomy you have.

You can also call wp_defer_term_counting( true ) before inserting new rows, and then after adding your posts, catch up on the counts by calling wp_defer_term_counting( false ).

There's a sql script written by someone else that does the job - updates counts for product categories in woocommerce or any other category counts.

Only takes a few seconds to run as well:

Answer 3

Example for the answer of goldenapples:

$update_taxonomy = 'my_taxonomy';
$get_terms_args = array(
        'taxonomy' => $update_taxonomy,
        'fields' => 'ids',
        'hide_empty' => false,
        );

$update_terms = get_terms($get_terms_args);
wp_update_term_count_now($update_terms, $update_taxonomy);

In my opinion the best way to do this is by using WP-CLI. There's a command for that:

$ wp term recount category
