能用代碼的就儘量不用插件，為新的 WooCommerce 客户申請優惠券 ，請遵循以下步驟： –

1 、在應用下面​​的代碼前，你必須創建一個新的優惠券。我創建了一個新的優惠券名稱’firstlove「

2 、現在，您可以下面複製並粘貼代碼到你的主題的 functions.php

/**
* Frontend validate new customer only coupon code
* hook: woocommerce_after_checkout_validation
*/
add_action('woocommerce_after_checkout_validation','check_new_customer_coupon', 0);

function check_new_customer_coupon(){
global $woocommerce;
// you might change the firstlove to your coupon
$new_cust_coupon_code = 'firstlove';

$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;
}
}

}

3 、如果你添加成功了，那麼現在可以嘗試註冊一個新用户然後去後台下單試試。

如果上面的代碼不能滿足您的要求，您可以隨意修改。
