在Block类的_construct(不是构造方法)方法中加入以下代码: Php代码 public function _construct() { $this->addData( array( 'cache_lifetime' => 3600, 'cache_tags' => array(Mage_Catalog_Model_Product::CACHE_TAG), 'cache_key' => 'productfaq_'.Mage::registry('product')->getId().'_'.Mage::app()->getStore()->getId() . '_' . Mage::getDesign()->getPackageName() . '_' . Mage::getDesign()->getTheme('template') . '_' . Mage::getSingleton('customer/session')->getCustomerGroupId() ) ); parent::_construct(); } cache_key必须唯一。 在获得数据的方法中加入: Php代码 $faq_data = @unserialize( Mage::app()->loadCache($this->getCacheKey()) ); //从数据库取出数据并存入到faq_data 中 if (!$faq_data) { $faq_data = array(); ... $faq_data[]=array('customer_id' => $customerId, 'name' => $sName, 'avatar' => $sAvatar, 'question' => $sQuestion, 'answer' => $sAnswer, ); } Mage::app()->saveCache(serialize($faq_data), $this->getCacheKey(), $this->getCacheTags(),$this->getCacheLifetime());
