magento静态块(static block),仅包含一些静态的html内容,不涉及数据库存取,比如像:一些文字和图片链接,网站页脚部分等。建立static block很简单,Magento后台提供一个功能,可以方便的创建、编辑、管理static block。可以在【管理员后台】》【CMS】》【Static Blocks】菜单找到。
<default>
<reference name="footer">
<block type="cms/block" name="cms_footer_links" before="footer_links">
<!--
The content of this block is taken from the database by its block_id.
You can manage it in admin CMS -> Static Blocks
-->
<action method="setBlockId"><block_id>footer_links</block_id></action>
</block>
</reference>
</default>
然后,在模板文件footer.phtml中输出:
echo $this->getChildHtml('footer_links');
另外一种方式更简单,不需要配置layout文件,就可以直接在php代码中输出静态块内容:
echo $this->getLayout()->createBlock('cms/block')->setBlockId('footer_links')->toHtml();
确实很简单,但Magento在背后做了大量的工作,在文件app/code/core/Mage/Cms/Block/Block.php中,可以看到这些辛苦的步伐:
/**
* Cms block content
*
* @category Mage
* @package Mage_Cms
* @author Magento Core Team <core@magentocommerce.com>
*/
class Mage_Cms_Block_Block extends Mage_Core_Block_Abstract
{
protected function _toHtml()
{
if (!$this->_beforeToHtml()) {
return '';
}
$html = '';
if ($blockId = $this->getBlockId()) {
$block = Mage::getModel('cms/block')
->setStoreId(Mage::app()->getStore()->getId())
->load($blockId);
if (!$block->getIsActive()) {
$html = '';
} else {
$content = $block->getContent();
$processor = Mage::getModel('core/email_template_filter');
$html = $processor->filter($content);
}
}
return $html;
}
}
