添加自定义电子邮件 Woocommerce

Question

我有一个用于管理我的货件的插件，它有两种自定义状态：等待发货和已发货。

我尝试添加在订单传递到发货时发送的电子邮件。

我在 Stack Overflow 上找到了这个：Woocommerce Refund Email 但我可以弄清楚它是如何工作的

这是我的插件文件代码：
我根据 helgatheviking 和 Adrien Leber 的建议更新了我的代码

function shippement_tracking_filter_actions( $actions ){
    $actions[] = "woocommerce_order_status_shipped";
    return $actions;
}
add_filter( 'woocommerce_email_actions', 'shippement_tracking_filter_actions' );

function add_expedited_order_woocommerce_email( $email_classes ) {
    require( 'includes/class-wc-expedited-order-email.php' );
    $email_classes['WC_Expedited_Order_Email'] = new WC_Expedited_Order_Email();
    return $email_classes;
}
add_filter( 'woocommerce_email_classes', 'add_expedited_order_woocommerce_email' );`

还有我的班级：

class WC_Expedited_Order_Email extends WC_Email {
    public function __construct() {

        $this->id               = 'expedited_order_tracking';
        $this->customer_email   = true;
        $this->title            = __( 'Shippement Traking', 'customEmail' );
        $this->description      = __( 'Sent tracking email to customer', 'customEmail' );
        $this->heading          = __( 'Your {site_title} order is shipped', 'customEmail' );
        $this->subject          = __( 'Your {site_title} order from {order_date} is shipped', 'customEmail' );

        $this->template_html    = 'emails/customer-order_tracking.php';
        $this->template_plain   = 'emails/plain/customer-order_tracking.php';

        add_action( 'woocommerce_order_status_shipped', array( $this, 'trigger' ) );

        parent::__construct();
    }

    public function trigger( $order_id )
    {
        var_dump($order_id);die();
    }

当我更改订单状态时，什么也没有发生！我的触发函数从不调用。

谁能帮帮我？

我认为你误解了这部分：

function add_expedited_order_woocommerce_email( $email_classes ) {
   $email_classes['WC_Expedited_Order_Email'] = include( plugin_dir_path( __FILE__ ) . '/class-wc-expedited-order-email.php' );
   return $email_classes;
}

你必须先包含类文件，然后创建这个类的一个新实例：

function add_expedited_order_woocommerce_email( $email_classes ) {

    // include our custom email class
    require( 'includes/class-wc-expedited-order-email.php' );

    // add the email class to the list of email classes that WooCommerce loads
    $email_classes['WC_Expedited_Order_Email'] = new WC_Expedited_Order_Email();

    return $email_classes;

}

希望对你有帮助。
