Woocommerce で、新規顧客による最初の注文に 20% の割引を適用する方法を見つけようとしています。woocommerce_after_checkout_validation関数を使用してこれを行うことができるようですが、機能check_new_customer_couponしません。
関数.php:
add_action('woocommerce_after_checkout_validation','check_new_customer_coupon', 0);
function check_new_customer_coupon(){
global $woocommerce;
// you might change the name of your coupon
$new_cust_coupon_code = 'test';
$has_apply_coupon = false;
foreach ( WC()->cart->get_coupons() as $code => $coupon ) {
if($code == $new_cust_coupon_code) {
$has_apply_coupon = true;
}
}
if($has_apply_coupon) {
if(is_user_logged_in()) {
$user_id = get_current_user_id();
// retrieve all orders
$customer_orders = get_posts( array(
'meta_key' => '_customer_user',
'meta_value' => $user_id,
'post_type' => 'shop_order',
'numberposts'=> -1
) );
if(count($customer_orders) > 0) {
$has_ordered = false;
$statuses = array('wc-failed', 'wc-cancelled', 'wc-refunded');
// loop thru orders, if the order is not falled into failed, cancelled or refund then it consider valid
foreach($customer_orders as $tmp_order) {
$order = wc_get_order($tmp_order->ID);
if(!in_array($order->get_status(), $statuses)) {
$has_ordered = true;
}
}
// if this customer already ordered, we remove the coupon
if($has_ordered == true) {
WC()->cart->remove_coupon( $new_cust_coupon_code );
wc_add_notice( sprintf( "Coupon code: %s is only applicable for new customer." , $new_cust_coupon_code), 'error' );
return false;
}
} else {
// customer has no order, so valid to use this coupon
return true;
}
} else {
// new user is valid
return true;
}
}
}
