Question

我正在寻找一个Woocommerce挂钩，该挂钩将有助于在应用特定优惠券时根据2种不同的产品类别限制来更改折扣百分比。

例如，如果客户添加特定的优惠券，我想：

如果购物车商品来自产品类别A，则它将为该商品提供10％的折扣。如果它属于产品类别B，则将对该商品给予20％的折扣

我找到了此代码，但仍可以从WooCommerce的Coupons中获得优惠券折扣。

add_filter( 'woocommerce_coupon_get_discount_amount', 'alter_shop_coupon_data', 20, 5 );
function alter_shop_coupon_data( $round, $discounting_amount, $cart_item, $single, $coupon ){

    ## ---- Your settings ---- ##

    // Related coupons codes to be defined in this array (you can set many)
    $coupon_codes = array('10percent');

    // Product categories at 20% (IDs, Slugs or Names)  for 20% of discount
    $product_category20 = array('hoodies'); // for 20% discount

    $second_percentage = 0.2; // 20 %

    ## ---- The code: Changing the percentage to 20% for specific a product category ---- ##

    if ( $coupon->is_type('percent') && in_array( $coupon->get_code(), $coupon_codes ) ) {
        if( has_term( $product_category20, 'product_cat', $cart_item['product_id'] ) ){
            $original_coupon_amount = (float) $coupon->get_amount();
            $discount = $original_coupon_amount * $second_percentage * $discounting_amount;
            $round = round( min( $discount, $discounting_amount ), wc_get_rounding_precision() );
        }
    }
    return $round;
}

此挂钩获取已触发，您的购物车获取了更新。所以也许这是正确的钩子。尝试使代码适合于foreach。如果您需要更多帮助，请告诉我。

add_action( 'woocommerce_update_cart_action_cart_updated', 'on_action_cart_updated', 20, 1 );
function on_action_cart_updated( $cart_updated ) {

    $applied_coupons = WC()->cart->get_applied_coupons();

    if ( count( $applied_coupons ) > 0 ) {
        foreach ( $applied_coupons as $coupon ) {
            $round = .....
        }

        $cart_subtotal = WC()->cart->get_cart_subtotal();
        $new_value     = $cart_subtotal - $round;

        WC()->cart->set_total( $new_value );

        if ( $cart_updated ) {
            // Recalc our totals
            WC()->cart->calculate_totals();
        }
    }
}
