function ts_capture_selected_subscription_plan() {
    if (is_product()) {
        ?>
        <script type="text/javascript">

    if ($subscription_plan) {
        $cart_item_data['subscription_plan'] = $subscription_plan;
    }
    return $cart_item_data;
}

// Adjust the cart item price based on the selected radio option
add_action('woocommerce_before_calculate_totals', 'ts_adjust_cart_item_price', 20, 1);

function ts_adjust_cart_item_price($cart) {
    if (is_admin() && !defined('DOING_AJAX')) return;

            $product = $cart_item['data'];

            $original_price = $product->get_regular_price();

                $additional_price = 15;
            }

            $new_price = $original_price + $additional_price;
