Php Woocommerce：获得产品变体标题

我正在编写插件，无法获得正确的变体标题 在Woodcommerce中，我使用的变体称为“展开层压”。但当我试图得到一个变体的标题时，我得到了：“变体#781图表”

这是使用的代码：

foreach ($order->get_items() as $item) {
    $product_variation_id = $item['variation_id'];
    if ($product_variation_id)
    {
        $product = new WC_Product($product_variation_id);
        $productname = get_item_variations($product_variation_id);
    }
    else
    { 
        $product = new WC_Product($item['product_id']);
        $productname = get_the_title($item['product_id']);
    } 
}

如何获得正确的标题？

我刚才偶然发现了这个问题，正在寻找“快速”解决方案。因为没有人给出答案，我想我会的

我刚刚使用WordPress

get\u post\u meta

获取属性选项。这是存储所有选项标题的地方（变体标题是产品选项）

将返回一个数组

    [attribute_options] => Array
    (
        [0] => Some Variation Title
    )

我实际上是在查找这个，试图找出答案，这是我的解决方案，因为变体标题返回了一个slug

在WC 2.4.13上测试

$variation = new WC_Product_Variation($variation_id);
$title_slug = current($variation->get_variation_attributes());

$results = $wpdb->get_results("SELECT * FROM wp_terms WHERE slug = '{$title_slug}'", ARRAY_A);
$variation_title = $results[0]['name'];

以下是此问题的解决方案，已通过WooCommerce 3.2.6

//Loop through each item from the cart
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
  //get the current product ID
  $product_id  = $cart_item['product_id'];
  //first - check if product has variations
  if(isset($cart_item['variation']) && count($cart_item['variation']) > 0 ){
    //get the WooCommerce Product object by product ID
    $current_product = new  WC_Product_Variable($product_id);
    //get the variations of this product
    $variations = $current_product->get_available_variations();
    //Loop through each variation to get its title
    foreach($variations as $index => $data){
      get_the_title($data['variation_id']);
    }
  }
}

在该函数中，您可以将分隔符“”更改为空格或任何所需的内容，以返回输入变量的标题

function get_variation_title($variation) {

    $str_name = '';

    $arr_attributes = $variation -> get_variation_attributes(FALSE);

    if (is_array($arr_attributes)) {
        foreach($arr_attributes as $attribute_slug=> $variation_slug) {
            $term = get_term_by('slug', $variation_slug, $attribute_slug);

            if (isset($term)) {
                if (strlen($str_name) > 0) $str_name.= ', ';
                $str_name.= $term -> name;
            }
        }
    }

    return $str_name;
}

function get_variation_title($variation) {

    $str_name = '';

    $arr_attributes = $variation -> get_variation_attributes(FALSE);

    if (is_array($arr_attributes)) {
        foreach($arr_attributes as $attribute_slug=> $variation_slug) {
            $term = get_term_by('slug', $variation_slug, $attribute_slug);

            if (isset($term)) {
                if (strlen($str_name) > 0) $str_name.= ', ';
                $str_name.= $term -> name;
            }
        }
    }

    return $str_name;
}
