两年前，我修改了Skyverge的代码，以便在客户在线订购（[{Adding a custom woocommerce email based on the product attribute）时生成WC自定义电子邮件。
一切正常，但是我现在想用新的Woocommerce版本进行更新。深入研究后，我在下面编写了代码，但是我准备的插件不再起作用。
plugin文件夹包含一个基本文件woocommerce-custom-order-email.php，一个包含自定义类的类文件夹（它们是基于两个不同属性的两个）和一个包含电子邮件自定义模板的文件夹。
woocommerce-custom-order-email.php代码
/**
* Add a custom email to the list of emails WooCommerce should load
*
* @since 1.0
* @param array $email_classes available email classes
* @return array filtered available email classes
*/
class Custom_WC_Email {
/**
* Custom_WC_Email constructor.
*/
public function __construct() {
// Filtering the emails and adding our own email.
add_action( 'woocommerce_email_classes', array( $this, 'register_email' ), 90, 1 );
// Absolute path to the plugin folder.
}
/**
* Add a custom email to the list of emails WooCommerce should load
*
* @param array $email_classes available email classes
* @return array filtered available email classes
*/
public function register_email( $emails ) {
require_once 'classes/class-wc-email-customer-processing-idp-order.php';
require_once 'classes/class-wc-email-customer-processing-csr-order.php';
$emails['WC_Email_Customer_Processing_IDP_Order'] = new WC_Email_Customer_Processing_IDP_Order();
$emails['WC_Email_Customer_Processing_CSR_Order'] = new WC_Email_Customer_Processing_CSR_Order();
return $emails;
}
}
new Custom_WC_Email();

我认为问题出在触发器自定义代码中，但是我没有找到有效调试它的方法。有人有什么主意吗？
答案 0 :(得分：0)
好吧，我查看了@LoicTheAztec https://stackoverflow.com/a/44708344/4275508所发布的有关如何使用新的WC 3.0版本检索product_id的信息，并按如下所示修改了自定义代码
#!/usr/bin/python3
import pytz
import random
from datetime import datetime
randZoneName = random.choice(pytz.all_timezones)
randZone=datetime.now(pytz.timezone(randZoneName))
offset=randZone.strftime('%z')
print("(GMT%s:%s) %s"%(offset[:3],offset[3:],randZoneName))
但仍然无法正常工作。最糟糕的是它给了e内部错误
