应用优惠券时（属于某种类型），我通过以下方式将产品折扣价更改为正常价格：
add_action( 'woocommerce_before_calculate_totals', 'add_custom_price', 10, 1);
function add_custom_price( $cart_object) {
global $woocommerce;
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
$coupon = False;
if ($coupons = WC()->cart->get_applied_coupons() == False )
$coupon = False;
else {
foreach ( WC()->cart->get_applied_coupons() as $code ) {
$coupons1 = new WC_Coupon( $code );
if ($coupons1->type == 'percent_product' || $coupons1->type == 'percent')
$coupon = True;
}
}
if ($coupon == True)
foreach ( $cart_object->get_cart() as $cart_item )
{
$price = $cart_item['data']->regular_price;
$cart_item['data']->set_price( $price );
}
}
但是，如果我排除了一个类别，代码就会吓坏，因为它将购物车中的价格从销售更改为常规，并且不添加折扣。
如何解决此问题，以使排除的类别不会更改为正常价格？
要排除某些类别，您可以has_term()在遍历购物车项目时使用
所以你得到：
function action_woocommerce_before_calculate_totals( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 ) return;
// Specific categories: the term name/term_id/slug. Several could be added, separated by a comma
$excluded_categories = array( 63, 15, 'categorie-1' );
// Initialize
$coupon_flag = false;
// Loop through applied coupons
foreach ( $cart->get_applied_coupons() as $coupon_code ) {
// Get an instance of the WC_Coupon Object
$coupon = new WC_Coupon( $coupon_code );
// Only for certain types, several can be added, separated by a comma
if ( in_array( $coupon->get_discount_type(), array( 'percent', 'percent_product' ) ) ) {
$coupon_flag = true;
break;
}
}
// True
if ( $coupon_flag ) {
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item ) {
// Get product ID in
$product_id = $cart_item['product_id'];
// NOT contains the definite term
if ( ! has_term( $excluded_categories, 'product_cat', $product_id ) ) {
// Get regular price
$regular_price = $cart_item['data']->get_regular_price();
// Set new price
$cart_item['data']->set_price( $regular_price );
}
}
}
}
add_action( 'woocommerce_before_calculate_totals', 'action_woocommerce_before_calculate_totals', 10, 1 );
