首先，我們在優惠券管理頁面添加一個設置字段，用于設置優惠券的電子郵件收件人：
// 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();
}
}
如果已為所應用的優惠券設置了電子郵件收件人，則系統會將每張所應用的優惠券的電子郵件發送到已提交的訂單。
警告！僅選擇以下功能之一：
對于 woocommerce 版本 最高 4.3 （新掛鉤）
// 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
}
}
}
}
或者對于所有 WooCommerce 版本（自版本 3.0 起）
// 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
}
}
}
}
