Question

wp_update_comment_count( int|null $post_id,  bool $do_deferred = false )

Updates the comment count for post(s).

---

description

When $do_deferred is false (is by default) and the comments have been set to be deferred, the post_id will be added to a queue, which will be updated at a later date and only updated once per post ID.

If the comments have not be set up to be deferred, then the post will be updated. When $do_deferred is set to true, then all previous deferred post IDs will be updated along with the current $post_id.

$do_deferred

(bool) (Optional) Whether to process previously deferred post comment counts.

Default value: false

返回值
