Runs when the order status changes (uses the order’s new status in the action hook name).
do_action( 'pmpro_order_status_' . $this->status, $this, $this->original_status );
There are six built-in forms of this hook (more if you have added custom order statuses or are using an Add On that extends). Hook variations include:
- object; The current member order object
- string; The original status before changing to the new status
