给Magento常用的Block添加缓存_magento教程_php教程

1、产品页面

修改文件：app\code\local\Mage\Catalog\Block\Product\View.php

在_prepareLayout方法前面添加方法：

[php] view plaincopy在CODE上查看代码片派生到我的代码片

protected function _construct()

{

$this->addData(array(

'cache_lifetime' => 86400,

'cache_tags' => array(Mage_Catalog_Model_Product::CACHE_TAG . "_" . $this->getProduct()->getId()),

'cache_key' => $this->getProduct()->getId(),

));

}

这里使用catalog_product_productid使用cache_tags

2、分类页面

修改文件：app\code\local\Mage\Catalog\Block\Category\View.php

在_prepareLayout方法前面添加方法：

[php] view plaincopy在CODE上查看代码片派生到我的代码片

protected function _construct()

{

$this->addData(array(

'cache_lifetime' => 86400,

'cache_tags' => array($this->getCacheKeyInfo()),

'cache_key' => $this->getCacheKeyInfo(),

));

}

public function getCacheKeyInfo(){

$paging = '';

$limit = '';

$mode = '';

$order = '';

$productListBlock = $this->getChild('product_list');

if ($productListBlock){

$toolbarBlock = $productListBlock->getChild('product_list_toolbar');

if($toolbarBlock){

$paging = $toolbarBlock->getCurrentPage();

$limit = $toolbarBlock->getLimit();

$mode = $toolbarBlock->getCurrentMode();

$order = $toolbarBlock->getCurrentOrder();

}

return array(

'CATEGORY_VIEW',

Mage::app()->getStore()->getId(),

Mage::getDesign()->getPackageName(),

Mage::getDesign()->getTheme('template'),

$this->getCurrentCategory()->getId(),

'template' => $this->getTemplate(),

$paging,

$limit,

$mode,

$order

);

}

3、cms/page页面

修改文件：app\code\local\Mage\Cms\Block\Page.php

在_prepareLayout方法前面添加方法：

[php] view plaincopy在CODE上查看代码片派生到我的代码片

const CACHE_KEY = 'cms_page';

protected function _construct()

{

$this->addData(array(

'cache_lifetime' => 86400,

'cache_tags' => array('cms-'.$this->getPage()->getIdentifier()),

'cache_key' => $this->getCacheKey(),

));

}

public function getCacheKey()

{

$storeId = $this->getStoreId();

$currencyCode = Mage::app()->getStore()->getCurrentCurrencyCode();

$uri = $this->getRequest()->getRequestUri() . self::CACHE_KEY;

return $storeId.$uri.$currencyCode;

}

这里使用cms-pageidentifier作为cache_tags
