没有调用Woocommerce订单删除钩子回调

Question

I'm trying to hook a function to the order deletion (when permanently delete is clicked from admin page) but for some reason the function isn't called. My code looks something like

add_action('woocommerce_before_delete_order_item', function($id) {
    $order = new WC_Order($id);
    //do some stuff with order meta data
}, 10, 1);

I tried to throw and exception inside the function but no error occurred. Can somebody help?

The woocommerce_before_delete_order_item action runs every time an item is deleted from an order, not every time an order is deleted. You need to use the before_delete_post hook:

add_action('before_delete_post', function($id) {
    global $post_type;

    if($post_type !== 'shop_order') {
        return;
    }

    $order = new WC_Order($id);
    //do some stuff with order meta data
}, 10, 1);

Depending on what it is you want to do, you may want to hook on to the action at an earlier stage by changing the priority argument from 10 to something smaller.
