在 WooCommerce 订单上使用优惠券代码时发送电子邮件通知

Question

如何在使用特定优惠券时向业务合作伙伴发送订单通知？

我在这里找到了使用优惠券时实例的解决方案：

但是，提交订单后，我需要找到一个解决方案，因为应用优惠券后并不总是提交订单。

每张优惠券都有自己的电子邮件地址。

Answer 1

首先我们在管理员优惠券页面中添加一个设置字段，以设置优惠券的电子邮件收件人：

// Add a custom field to Admin coupon settings pages
add_action( 'woocommerce_coupon_options', 'add_coupon_text_field', 10 );
function add_coupon_text_field() {
    woocommerce_wp_text_input( array(
        'id'                => 'email_recipient',
        'label'             => __( 'Email recipient', 'woocommerce' ),
        'placeholder'       => '',
        'description'       => __( 'Send an email notification to a defined recipient' ),
        'desc_tip'    => true, // Or false

    ) );
}

// Save the custom field value from Admin coupon settings pages
add_action( 'woocommerce_coupon_options_save', 'save_coupon_text_field', 10, 2 );
function save_coupon_text_field( $post_id, $coupon ) {
    if( isset( $_POST['email_recipient'] ) ) {
        $coupon->update_meta_data( 'email_recipient', sanitize_text_field( $_POST['email_recipient'] ) );
        $coupon->save();
    }
}

如果已为所应用的优惠券设置了电子邮件收件人，则会将每张应用的优惠券的电子邮件发送到已提交的订单。

Caution! choose only one of the following functions:

对于 woocommerce 版本最高 4.3 （新挂钩）

// For Woocommerce version 4.3+
add_action( 'woocommerce_checkout_order_created', 'custom_email_for_orders_with_applied_coupon' );
function custom_email_for_orders_with_applied_coupon( $order ){
    $used_coupons = $order->get_used_coupons();

    if( ! empty($used_coupons) ){
        foreach ( $used_coupons as $coupon_code ) {
            $coupon    = new WC_Coupon( $coupon_code ); // WC_Coupon Object
            $recipient = $coupon->get_meta('email_recipient'); // get recipient

            if( ! empty($recipient) ) {
                $subject = sprintf( __('Coupon "%s" has been applied'), $coupon_code );
                $content = sprintf( __('The coupon code "%s" has been applied by a customer'), $coupon_code );
                wp_mail( $recipient, $subject, $content ); // Send email
            }
        }
    }
}

或所有 WooCommerce 版本 （自版本 3.0）

// For all Woocommerce versions (since 3.0)
add_action( 'woocommerce_checkout_update_order_meta', 'custom_email_for_orders_with_applied_coupon' );
function custom_email_for_orders_with_applied_coupon( $order_id ){
    $order = wc_get_order( $order_id );

    $used_coupons = $order->get_used_coupons();

    if( ! empty($used_coupons) ){
        foreach ( $used_coupons as $coupon_code ) {
            $coupon    = new WC_Coupon( $coupon_code ); // WC_Coupon Object
            $recipient = $coupon->get_meta('email_recipient'); // get recipient

            if( ! empty($recipient) ) {
                $subject = sprintf( __('Coupon "%s" has been applied'), $coupon_code );
                $content = sprintf( __('The coupon code "%s" has been applied by a customer'), $coupon_code );
                wp_mail( $recipient, $subject, $content ); // Send email
            }
        }
    }
}

代码进入您的活动子主题（或活动主题）的 functions.php 文件。已测试并有效。
