WooCommerce 挂钩 woocommerce_cancelled_order

再会，

这是我第一次使用 stackoverflow，很高兴认识大家。

不管怎样，我正在为 WooCommerce 编写一个插件，当订单取消时我会自动退款。当我在没有钩子的情况下在单独的文件中手动执行它时，我的代码工作正常，但是，使用我的钩子它似乎无法执行。我正在执行以下操作：

add_action('woocommerce_cancelled_order','change_status_to_refund', 10, 1);
function change_status_to_refund( $order_id ) {
wp_redirect( home_url() );
   $order = new WC_Order( $order_id );

if( 'refunded' == $order->get_status() ) {
     return false;
 }


if(!($order->is_paid())) {
    return false;
}


$noRefundLimit = 24 * 60; //in minutes until booking
$customer_orders = get_posts( array(
 'numberposts' => 1,
 'post_parent' => $order_id,
 'post_type'   => 'wc_booking', // WC orders post type
 'post_status' => 'paid, complete' // Only paid, completed bookings
 ) );
 $bookingId = current($customer_orders)->ID;

 $bookingStart = current(get_post_meta($bookingId, "_booking_start"));
 $time = (new DateTime($bookingStart, new 
 DateTimeZone("America/Los_Angeles")))->getTimestamp();
 $nowTime = (new DateTime())->getTimestamp();
 $difference = round(($time - $nowTime)/60);//in minutes

 if($difference >= $noRefundLimit) {
     $refundPercentage = 1; //how much will we give back? fraction of 1.
     // Get Items
     $order_items   = $order->get_items();

     // Refund Amount
       $refund_amount = 0;
     // Prepare line items which we are refunding
     $line_items = array();

     if ( $order_items ) {
       foreach( $order_items as $item_id => $item ) {
        $refund_amount += $item->get_total();
       }
     }
     $refund_amount = ($refund_amount * $refundPercentage);
     $refund_reason = "Order Cancelled";
     $refund = wc_create_refund( array(
       'amount'         => $refund_amount,
       'reason'         => $refund_reason,
       'order_id'       => $order_id,
       'line_items'     => $line_items,
       'refund_payment' => true
       ));

       var_dump($refund);

       $order->update_status('wc-refunded', 'Order Cancelled And Completely 
Refunded');
       $order->save();
}

我添加了第一个重定向行，其唯一目的是测试它是否重定向，但事实并非如此！知道为什么这个钩子没有触发吗？

感谢您的评论。看来 woocommerce_order_status_cancelled 钩子很好，但参数是 $order_id。经过大量的调试后，我得到以下结果：

add_action( 'woocommerce_order_status_cancelled', 'change_status_to_refund', 
21, 1 );
function change_status_to_refund( $order_id ) {

$order = new WC_Order( $order_id );      

$noRefundLimit = 24 * 60; //in minutes until booking

global $wpdb;
$querystr = "
SELECT $wpdb->posts.* 
FROM $wpdb->posts 
WHERE $wpdb->posts.post_parent = $order_id
";

$pageposts = $wpdb->get_results($querystr, OBJECT);

 $bookingId = current($pageposts)->ID;

 $bookingStart = current(get_post_meta($bookingId, "_booking_start"));
 $time = (new DateTime($bookingStart, new 
 DateTimeZone("America/Los_Angeles")))->getTimestamp();
 $nowTime = (new DateTime())->getTimestamp();
 $difference = round(($time - $nowTime)/60);//in minutes

 if($difference >= $noRefundLimit) {
     $refundPercentage = 1; //how much will we give back? fraction of 1.
     // Get Items
     $order_items   = $order->get_items();

     // Refund Amount
       $refund_amount = 0;
     // Prepare line items which we are refunding
     $line_items = array();

     if ( $order_items ) {
       foreach( $order_items as $item_id => $item ) {
        $refund_amount += $item->get_total();
       }
     }
     $refund_amount = ($refund_amount * $refundPercentage);
     $refund_reason = "Order Cancelled";
     $refund = wc_create_refund( array(
       'amount'         => $refund_amount,
       'reason'         => $refund_reason,
       'order_id'       => $order_id,
       'line_items'     => $line_items,
       'refund_payment' => true
       ));

       $order->update_status('wc-refunded', 'Order Cancelled And Completely 
        Refunded');
     }
}

我遇到了一些问题。即使订单已付款， $order->is_paid() 返回 false （我认为这是因为状态从已付款更改为已取消/退款），所以我的代码甚至没有达到那么远。然后 get_posts 没有按预期工作。我被迫使用$wpdb。之后我的代码就起作用了。
