This page shows how to display your own message in the cart and checkout: a welcome for referred friends, or a reminder for advocates who haven’t used their coupons.
Built-in options first
- Cart Message in Settings → Friend Reward appears when the friend discount is applied. See Friend reward settings.
- With Popup Maker, the Referral link condition shows a popup to visitors who arrive through a referral link. See Show the referral link after checkout.
- Advocates see their unused coupons in My Account → Refer a Friend.
Snippets
Read Add code snippets safely first. Both snippets are checked with version 4.4.12. They work with the classic and block cart and checkout.
Welcome referred friends
add_action( 'template_redirect', function () {
$message = 'Welcome! A friend sent you here, so your first order is discounted.';
if ( empty( $_COOKIE['gens_raf'] ) || ! function_exists( 'is_cart' ) || ( ! is_cart() && ! is_checkout() ) || is_wc_endpoint_url( 'order-received' ) ) {
return;
}
if ( ! wc_has_notice( $message, 'notice' ) ) {
wc_add_notice( $message, 'notice' );
}
} );The message shows to anyone with a referral cookie, including customers who aren’t eligible for the discount. Keep the wording general, or check eligibility in Friend discount not applied before promising a discount.
Remind advocates about unused coupons
add_action( 'template_redirect', function () {
$message = 'You have unused referral coupons. Add them in the coupon field to get your discount.';
if ( ! is_user_logged_in() || ! function_exists( 'is_checkout' ) || ! is_checkout() || is_wc_endpoint_url( 'order-received' ) ) {
return;
}
$coupons = get_posts( array(
'post_type' => 'shop_coupon',
'post_status' => 'publish',
'numberposts' => 20,
'meta_query' => array(
array( 'key' => 'customer_email', 'value' => wp_get_current_user()->user_email, 'compare' => 'LIKE' ),
array( 'key' => 'usage_count', 'value' => '0' ),
),
) );
foreach ( $coupons as $post ) {
if ( strpos( $post->post_title, 'RAF-' ) !== 0 ) {
continue;
}
$expires = ( new WC_Coupon( $post->post_title ) )->get_date_expires();
if ( ! $expires || $expires->getTimestamp() > time() ) {
if ( ! wc_has_notice( $message, 'notice' ) ) {
wc_add_notice( $message, 'notice' );
}
return;
}
}
} );To apply the coupons for them instead, see Apply earned coupons automatically at checkout.
Check it worked
- For the welcome message, open a referral link in a private window, add a product and open the cart.
- For the reminder, log in as a customer with an unused
RAF-…coupon and open the checkout.
