WooCommerce 不应该在订单是订阅父时发送订单完成邮件

Question

当客户购买订阅时，我尝试取消发送 WooCommerce 默认订单完成邮件。 WooCommerce 为该订阅创建父订单。 当我们关闭该父订单时，客户将收到订单完成邮件。 然后我们尝试不阻止，但仅针对订阅的父订单。

我找到了这个答案，但它用于更新已完成的邮件。

有一个 info order_type应该存储信息，如果它是订阅父订单或不是，如何访问该值？

如果它是父订阅订单，也许还有一种方法可以通过wcs_order_contains_subscription()检查。 （ https://docs.woocommerce.com/document/subscriptions/develop/functions/order-cart-functions/ ）

像这样的东西： wcs_order_contains_subscription( $order, $order_type )

更新：使用新信息，这是当前状态：

// Conditionally remove action to send order completed email for subscription parent order

function unhook_order_complete_email_subscription_parent($email_class) {

    // Check whether to send the parent order completed email or not
    $send_parent_completed_email = order_type(parent);

    if (!$send_parent_completed_email) {

        // Remove action to prevent email from being sent
        remove_action(
            "woocommerce_order_status_completed_notification",
            array(
                $email_class->emails["WC_Email_Customer_Completed_Order"],
                "trigger"
            )
        );
    }
}

add_action("woocommerce_order_status_changed", "unhook_order_complete_email_subscription_parent");

Answer 1

没有像order_type()这样的 function 。 这应该可以解决您的问题：

// Conditionally remove action to send order completed email for subscription parent order

function unhook_order_complete_email_subscription_parent($order_id) {
    $email_class = wc()->mailer()->get_emails();
    
    // Check whether to send the parent order completed email or not
    $order = wc_get_order($order_id);
    if ($order && !$order->get_parent_id()) {
        // Remove action to prevent email from being sent
        remove_action(
            "woocommerce_order_status_completed_notification",
            array(
                $email_class->emails["WC_Email_Customer_Completed_Order"],
                "trigger"
            )
        );
    }
}

add_action("woocommerce_order_status_changed", "unhook_order_complete_email_subscription_parent");

编辑：

这是一种更好的方法。 如果订单是父订单， get_parent_id()将返回 0，否则如果订单是子订单，它将返回parent_id 。

function enable_email($order) {
    // We have to restore the configuration of what we disabled after we are done with our hack
    if ($order->get_parent_id() != 0 && ($status = get_transient( "tmp_completed_order_email" )) !== false) {
        wc()->mailer()->emails['WC_Email_Customer_Completed_Order']->enabled = $status;        
    }
}

function disable_email($order)
{
    if ($order->get_parent_id() != 0) { // It is a child
        // Store the current configuration in a temporary place.
        $current_status = wc()->mailer()->emails['WC_Email_Customer_Completed_Order']->enabled;

        // Everything should be done in 10 seconds. Lets keep the data till then
        set_transient( 'tmp_completed_order_email', $current_status, 10 );

        // Disabled completed order email
        wc()->mailer()->emails['WC_Email_Customer_Completed_Order']->enabled = 'no';
    }
}
add_action("woocommerce_before_order_object_save", "disable_email");
add_action("woocommerce_after_order_object_save", "enable_email");
