Woocommerce如何获得所选的变化产品价格

Question

我试图在弹出窗口中显示产品变动价格，您可以分期查看产品价格。现在，它仅获得产品的最低价格。我试图在下拉菜单中选择一种价格来更改价格。

问题是我找不到如何获得变动价格。

    $product = wc_get_product( get_the_id());

if( is_a( $product, 'WC_Product' ) || ! empty( $product ) ) {
    
    //* 1. Variable product (min and max)
    if ( $product->is_type('variable') ){
        $price_min = $product->get_variation_price('min'); // Float number
        $price_max = $product->get_variation_price('max'); // Float number

        $formatted_price_range = $product->get_price_html(); // Html formatted price range  
        
        $deadline = 12;
        $rate = 25;

        $rate_sum = ($price / 100) * $rate;
        $total_sum = $price + $rate_sum;
        $base_per_month = $total_sum / $deadline;   
        $base_per_month_r = round($base_per_month);
        $total_sum_r = round($total_sum);
        
    } 

    // 2. Single product
    elseif ( $product->is_type('simple') ){
        $price = $product->get_price(); // Float number

        $formatted_price = $product->get_price_html(); // Html formatted price range
        
        $deadline = 12;
        $rate = 25;

        $rate_sum = ($price / 100) * $rate;
        $total_sum = $price + $rate_sum;
        $base_per_month = $total_sum / $deadline;   
        $base_per_month_r = round($base_per_month);
        $total_sum_r = round($total_sum);
    }
    else {
        echo "product is empty";
    }
}
