Question

所以，我试图在网格页面上显示颜色样本。

如果没有此代码，页面会在3秒左右呈现。

有了它，它会跳到12-15秒。

if($_product->isConfigurable())
{
    $cIds = Mage::getModel('catalog/product_type_configurable')->getUsedProductIds($_product); // Get all associated product ids
    // Pull a list of attributes we need for each simple product
    $cProd = Mage::getModel('catalog/product')->getCollection()
                ->addAttributeToFilter('entity_id',array('in'=>$cIds))
                ->addAttributeToSelect(array('color','color_family','color_tile','small_image','entity_id'))
                ->setOrder("size")
                ->load();

    $colors = array();
    $swatches = "";
    foreach($cProd as $_cProd)
    {
        if($_cProd->isSaleable()) // check if it's able to be sold
        {
            $c=$_cProd->getColor();
            if(!isset($colors[$c])) // check if we've seen this color before
            {
                $swatches .= "<div class = 'swatch'><img src='/media/catalog/product/".$_cProd->getColorTile()."' title='".$_cProd->getAttributeText("color")."' full='".$_cProd->getSmallImage()."' onmouseover='switchColor(this,\"mainimage-".$pid."\")'></div>";
                $colors[$c] = true;
            }
        }
    }
}

我还尝试通过将->load()切换为->group('color')->getSelect()来对集合进行分组，但这会引发错误或返回空白集。

我尝试了多种方法，但我不能加快速度。我错过了什么？我可以尝试不同的方法吗？

这很疯狂。您正在为列表中的每个产品加载一个集合，因此在昂贵地加载集合20或30次之后，最终可能会运行foreach循环20或30次。

方法1：

/**
 * @param Mage_Catalog_Model_Product $product
 * @return Varien_Data_Collection
 */
public function getFastUsedProducts(Mage_Catalog_Model_Product $product, Array $attributes = array())
{
    $catalogResource = Mage::getResourceModel('catalog/product_collection');

    if ($catalogResource->isEnabledFlat()) {
        $resource = Mage::getResourceSingleton('xxx/catalog_product_type_configurable');
        $productRows = $resource->getFastUsedProducts($product, $attributes);

        $products = new Varien_Data_Collection();
        if (!empty($productRows)) {
            foreach ($productRows as $productData) {
                $productData['id'] = $productData['entity_id'];

                $product = Mage::getModel('catalog/product');
                $product->setData($productData);

                $products->addItem($product);
            }
        }
    } else {
        // FALLBACK TO SLOW RETRIEVAL
        $products = $product->getTypeInstance()->getUsedProducts();
    }

    return $products;
}

和getFastUsedProducts的资源模型：

public function getFastUsedProducts(Mage_Catalog_Model_Product $product, Array $attributes = array())
    {
        if (!in_array('entity_id', $attributes)) $attributes[] = 'entity_id';

        /** @var Varien_Db_Adapter_Pdo_Mysql $readConnection */
        $readConnection = Mage::getSingleton('core/resource')->getConnection(Mage_Core_Model_Resource::DEFAULT_READ_RESOURCE);

        /* @var $select Varien_Db_Select */
        $select = $readConnection
        ->select()
        ->from(
        array(
                    'r' => Mage::getResourceSingleton('catalog/product_relation')->getMainTable()
        ),
        array('r.child_id')
        )
        ->where('r.parent_id = ?', (int) $product->getId());

        $childIds = $readConnection->fetchCol($select);

        if (empty($childIds)) return NULL;

        /** @var Mage_Catalog_Model_Resource_Product_Flat $flatTable */
        $flatTable = Mage::getResourceSingleton('catalog/product_flat');

        $availableAttributes = array_intersect($attributes, $flatTable->getAllTableColumns());

        /* @var $select Varien_Db_Select */
        $select = $readConnection
        ->select()
        ->from(
        Mage::getResourceSingleton('catalog/product_flat')->getMainTable(),
        $availableAttributes
        )
        ->where('entity_id IN (?)', $childIds);


        $productRows = $readConnection->fetchAll($select);

        return $productRows;
    }

/**
     * Retrieve simples grouped by an attribute code
     *
     * @param Mage_Catalog_Model_Product $product
     * @param $attributeCode
     * @return array
     */
    public function getGroupedSimples(Mage_Catalog_Model_Product $product, $attributeCode, Array $selectAttributes)
    {
        if (isset($this->_groupedSimplesMap[$product->getId()][$attributeCode])) {
            return $this->_groupedSimplesMap[$product->getId()][$attributeCode];
        }

        $index = array();

        $simples = Mage::getSingleton('xxx/catalog_product_type_configurable')->getFastUsedProducts($product, $selectAttributes);

        foreach ($simples as $simple) {
            $value = $simple->getData($attributeCode);
            if ($value == '' || isset($index[$value])) continue;

            $index[$value] = $simple;
        }

        $this->_groupedSimplesMap[$product->getId()][$attributeCode] = $index;

        return $index;
    }

和

<?php if ($_product->getTypeId() == Mage_Catalog_Model_Product_Type::TYPE_CONFIGURABLE) : ?>
<?php $_colorSimples = $this->helper('xxx/product_type_configurable')->getGroupedSimples($_product, 'color'); ?>
<?php $_showSidebar = count($_colorSimples) > 1; ?>
<?php endif; ?>

<div
    class="item-wrap <?php echo $_product->getTypeId(); ?><?php if ($_showSidebar) : ?> sb<?php endif; ?>">
    <div class="item-inner-wrap">
    <?php if ($_product->getTypeId() == Mage_Catalog_Model_Product_Type::TYPE_CONFIGURABLE) : ?>
    <?php if ($_showSidebar) : ?>
        <div class="additional-info simples-wrap">
            <ul class="simples">
            <?php foreach ($_colorSimples as $_simple) : ?>
                <li class="simple-item"
                    data-product-id="<?php echo $_simple->getId(); ?>"><img
                    src="<?php echo $this->helper('catalog/image')->init($_simple, 'thumbnail')->resize(46); ?>"
                    data-grid-src="<?php echo $this->helper('catalog/image')->init($_simple, 'small_image')->resize(226); ?>"
                    data-zoom-image="<?php echo $this->helper('catalog/image')->init($_simple, 'small_image')->resize(640); ?>"
                    width="46" height="46"
                    alt="<?php echo $this->stripTags($this->getImageLabel($_simple, 'small_image'), null, true) ?>" />
                </li>
                <?php endforeach; ?>
            </ul>
        </div>
        <?php endif; ?>
        <?php endif; ?>
....

Magento代码片段的执行时间非常长
