$out = “”;

foreach( $attributes as $attribute ) {

if ($attribute[‘is_variation’] ) {

$out .= ‘<optgroup label=”Изображение по aтрибуту ?’ . wc_attribute_label($attribute[‘name’]) . ‘?”>’;

foreach( wc_get_product_terms( $post->ID, $attribute[‘name’] ) as $term ){
if (false !== $term){

//$term = get_term_by(‘name’, $attribute_value, $attribute[‘name’]);
$out .= ‘<option value=”set_image_attribute” data-attribute-name=”‘ . $attribute[‘name’] . ‘” data-attribute-value=”‘ . $term->slug . ‘”>’ . $term->name. ‘</option>’;
