Woocommerce产品定制价格不接受woocommerce优惠券

Question

在我们的woocommerce商店，客户可以输入根据这些细节计算的产品和产品价格的定制宽度和高度。

例如，如果产品的初始价格为50。客户加上宽度=2，height=3，则该产品的价格将转到50*2*3=300。

为此，我们将使用以下代码

// Save custom field value in cart item as custom data
add_filter( 'woocommerce_add_cart_item', 'calculate_custom_cart_item_prices', 30, 3 );
function calculate_custom_cart_item_prices( $cart_item_data, $product_id, $variation_id ) {
    if ( isset($_POST['width']) && isset($_POST['height']) ) {
        // Get the correct Id to be used (compatible with product variations)
        $the_id = $variation_id > 0 ? $variation_id : $product_id;

        $product = wc_get_product( $the_id ); // Get the WC_Product object
        $product_price = (float) $product->get_price(); // Get the product price

        // Get the posted data
        $width  = (float) sanitize_text_field( $_POST['width'] );
        $height = (float) sanitize_text_field( $_POST['height'] );

        $new_price = $width * $height * $product_price; // Calculated price

        $cart_item_data['calculated-price'] = $new_price; // Save this price as custom data
    }
    return $cart_item_data;
}

// Set custom calculated price in cart item price
add_action( 'woocommerce_before_calculate_totals', 'set_calculated_cart_item_price', 20, 1 );
function set_calculated_cart_item_price( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // Loop through cart items
    foreach ( $cart->get_cart() as $cart_item ){
        if( ! empty( $cart_item['calculated-price'] ) ){
            // Set the calculated item price (if there is one)
            $cart_item['data']->set_price( $cart_item['calculated-price'] );
        }
    }

这是一种病毒，但问题是：

当客户对此产品使用50%的优惠券代码时，折扣为25，因为它是根据50*(50/100)=25计算的； 但是实际上新产品的价格是300，所以的折扣应该是300*(50/100)=150;

尝试将您的“calculate_custom_cart_item_prices”函数更新到类似的内容，看看这是否有帮助。

add_filter( 'woocommerce_add_cart_item', 'calculate_custom_cart_item_prices', 30, 2 );
function calculate_custom_cart_item_prices( $cart_item_data, $cart_item_key ) {
    if ( isset($_POST['width']) && isset($_POST['height']) ) {
        // Get the correct Id to be used (compatible with product variations)
        $the_id = $cart_item_data['variation_id'] > 0 ? $cart_item_data['variation_id'] : $cart_item_data['product_id'];

        $product = wc_get_product( $the_id ); // Get the WC_Product object
        $product_price = (float) $product->get_price(); // Get the product price

        // Get the posted data
        $width  = (float) sanitize_text_field( $_POST['width'] );
        $height = (float) sanitize_text_field( $_POST['height'] );

        $new_price = $width * $height * $product_price; // Calculated price

        $cart_item_data['calculated-price'] = $new_price; // Save this price as custom data
    }
    return $cart_item_data;
}

我对正在发生的事情的猜测是，Woocommerce发生了变化，改变了'woocommerce_add_cart_item‘过滤器的工作方式，因此您需要更新这个函数。
