我们刚刚将我们的网站从Magento 1.9.1.1升级为 Magento 1.9.3.3 。
不幸的是，我们的网站坏了，所以我调查了这个问题。 错误通知如下。
Fatal error: Uncaught Error: Call to undefined method
Mage_ConfigurableSwatches_Helper_Mediafallback :: attachProductChildrenAttributeMapping（）in /var/www/html/source/app/code/core/Mage/ConfigurableSwatches/Model/Observer.php:59堆栈追踪：＃0 / var / www / html / source / app / code / core / Mage / Core / Model / App.php（1358）：Mage_ConfigurableSwatches_Model_Observer-productListCollectionLoadAfter（Object（Varien_Event_Observer））＃1 /var/www/html/source/app/code/core/Mage/Core/Model/App.php(1337):Mage_Core_Model_App- _callObserverMethod（Object（Mage_ConfigurableSwatches_Model_Observer），'productListColl ...'，Object（Varien_Event_Observer））＃2 /var/www/html/source/app/Mage.php(448):Mage_Core_Model_App-dispatchEvent（'catalog_block_p ...'，数组）＃3 /var/www/html/source/app/code/core/Mage/Catalog/Block/Product/List.php(160):Mage :: dispatchEvent（'catalog_block_p ...'，Array）＃4 /var/www/html/source/app/code/core/Mage/Core/Block/Abstract.php(922):Mage_Catalog_Block_Product_Li in 第59行的/var/www/html/source/app/code/core/Mage/ConfigurableSwatches/Model/Observer.php
该代码块如下。
public function productListCollectionLoadAfter(Varien_Event_Observer $observer)
{
if (!Mage::helper('configurableswatches')->isEnabled()) { // check if functionality disabled
return; // exit without loading swatch functionality
}
/* @var $mediaHelper Mage_ConfigurableSwatches_Helper_Mediafallback */
$mediaHelper = Mage::helper('configurableswatches/mediafallback');
/** @var $priceHelper Mage_ConfigurableSwatches_Helper_List_Price */
$priceHelper = Mage::helper('configurableswatches/list_price');
/* @var $collection Mage_Catalog_Model_Resource_Product_Collection */
$collection = $observer->getCollection();
if ($collection
instanceof Mage_ConfigurableSwatches_Model_Resource_Catalog_Product_Type_Configurable_Product_Collection) {
// avoid recursion
return;
}
$products = $collection->getItems();
$mediaHelper->attachChildrenProducts($products, $collection->getStoreId());
$mediaHelper->attachProductChildrenAttributeMapping($products, $collection->getStoreId());
if ($priceHelper->isEnabled()) {
$priceHelper->attachConfigurableProductChildrenPricesMapping($products, $collection->getStoreId());
}
$mediaHelper->attachGallerySetToCollection($products, $collection->getStoreId());
/* @var $product Mage_Catalog_Model_Product */
foreach ($products as $product) {
$mediaHelper->groupMediaGalleryImages($product);
Mage::helper('configurableswatches/productimg')
->indexProductImages($product, $product->getListSwatchAttrValues());
}
}
跟随旧版块（Magento1.9.1.0）。
public function productListCollectionLoadAfter(Varien_Event_Observer $observer)
{
if (!Mage::helper('configurableswatches')->isEnabled()) { // check if functionality disabled
return; // exit without loading swatch functionality
}
/* @var $helper Mage_ConfigurableSwatches_Helper_Mediafallback */
$helper = Mage::helper('configurableswatches/mediafallback');
/* @var $collection Mage_Catalog_Model_Resource_Product_Collection */
$collection = $observer->getCollection();
if ($collection
instanceof Mage_ConfigurableSwatches_Model_Resource_Catalog_Product_Type_Configurable_Product_Collection) {
// avoid recursion
return;
}
$products = $collection->getItems();
$helper->attachChildrenProducts($products, $collection->getStoreId());
$helper->attachConfigurableProductChildrenAttributeMapping($products, $collection->getStoreId());
$helper->attachGallerySetToCollection($products, $collection->getStoreId());
/* @var $product Mage_Catalog_Model_Product */
foreach ($products as $product) {
$helper->groupMediaGalleryImages($product);
Mage::helper('configurableswatches/productimg')
->indexProductImages($product, $product->getListSwatchAttrValues());
}
}
要解决网站损坏问题，我在系统/目录/可配置样本/常规设置上禁用了色样设置。
然后，检索了我们的网站。但是，当然，色样功能不再起作用了。
为了确保此问题是否是核心错误，我在本地服务器上安装了原始Magento 1.9.3.3。但是，同样的问题。
有没有解决方案？

要解决此问题，我们检查了整个自定义模块。
app\code\local\Mage\ConfigurableSwatches\Helper\Mediafallback.php
旧的开发人员创建了这个自定义模块，以便新的Magento版本的Mediafallback.php不起作用。 这是正确的原始核心php文件。

在catalog_product_view部分的catalog.xml文件中添加js
<action method="addJs"><script>varien/product_options.js</script></action>
