Woocommerce - Afișarea prețului pentru variația activă a produsului

Am reușit să găsesc o soluție. Aceasta afișează prețul variantei sub/lângă butoanele radio.

Afișare preț variantă (când este dat un ID):

function get_product_variation_price($variation_id) {

global $woocommerce; 
$product = new WC_Product_Variation($variation_id);
return $product->get_price_html(); // Funcționează. Folosește această funcție dacă vrei prețul formatat
}

Găsire ID variantă, trimitere la funcția get_product_variation_price, apoi afișare preț:

///Afișare preț pentru butoanele radio selectate activ
$product_variations = $product->get_available_variations();
$arr_variations_id = array();
foreach ($product_variations as $variation) {
    $product_variation_id = $variation['variation_id'];
    $product_price = get_product_variation_price($product_variation_id);
    echo $product_price;
}

Afișarea butoanelor radio foreach:

foreach ( $options as $option ) {
    print_attribute_radio( $checked_value, $option, $option, $sanitized_name );
                                }

Foreach pentru butoane radio modificat cu cheie de array

foreach ( $options as $key=>$option ) {...}

Foreach combinat:

foreach ( $options as $key=>$option ) {
    print_attribute_radio( $checked_value, $option, $option, $sanitized_name );
    $product_variations = $product->get_available_variations();
    $variation_product_id = $product_variations [$key]['variation_id'];
    $product_price = get_product_variation_price($variation_product_id);
    printf ('%1$s</div> ', $product_price);
                                    }
