如果父母和孩子已知，获得可配置的选项和价值

Question

如果我有可配置的产品ID和关联的子产品ID，如何确定该组合使用的特定属性ID和选项？

Answer 1

让我们假设可配置的产品ID是 $mainProductId 儿童产品ID是 $childId.
您可以获取这样的可配置属性：

$product = Mage::getModel('catalog/product')->setStoreId(Mage::app()->getStore()->getId())->load($mainProductId);
$attributes = $product->getTypeInstance(true)->getConfigurableAttributesAsArray($product); 

现在您可以得到这样的子产品价值：

$child = Mage::getModel('catalog/product')->setStoreId(Mage::app()->getStore()->getId())->load($childId);
foreach ($attributes as $attribute){
    //this will get you the id of the option
    echo $attribute['store_label'].':'.$child->getData($attribute['attribute_code'])."<br />"; 
    //if you want the label of the option use the foreach below.
    foreach ($attribute['values'] as $value){
        $childValue = $child->getData($attribute['attribute_code']);
        if ($value['value_index'] == $childValue){
            echo $attribute['store_label'].':'.$value['store_label']."<br />";
        }
    }
}
