尝试通过 Magento 的全页缓存打孔动态内容

发布于 2024-12-15 05:25:08 字数 4000 浏览 3 评论 0原文

我正在使用 Magento Enterprise 1.10.1.1,需要在我们的产品页面上获取一些动态内容。我将当前时间插入一个块中以快速查看它是否正常工作,但似乎无法通过全页缓存。

我尝试了在这里找到的各种实现:

欢迎任何解决方案、想法、评论、建议。

这是我的代码:

    </placeholders>
</config>

    }

    public function receiveMessage() {
        if($this->message != '') {
            return $this->message;
        } 
        else {
            $this->createMessage('Hello World');
            return $this->message;
        }
    }

    protected function _toHtml() {
        $html = parent::_toHtml();

        if($this->att = $this->getMyCustom() && $this->getMyCustom() != '') {
            $html .= '<br />'.$this->att;
        } 
        else {

        $now = date('m-d-Y h:i:s A');
        $html .= $now;
        $html .= '<br />' ;
        }

        return $html;
    }

}

    protected function _getCacheId()
    {
        return 'HOMEPAGE_PRODUCTS' . md5($this->_placeholder->getAttribute('cache_id') . $this->_getIdentifier());
    }

    protected function _renderBlock()
    {
        $blockClass = $this->_placeholder->getAttribute('block');
        $template = $this->_placeholder->getAttribute('template');

        $block = new $blockClass;
        $block->setTemplate($template);
        return $block->toHtml();
    }

protected function _saveCache($data, $id, $tags = array(), $lifetime = null) { return false; }  

}

<?php echo $this->receiveMessage() ?>

<reference name="content">
    <block type="catalog/product_view" name="product.info" template="catalog/product/view.phtml">
            <block type="fido_example/view" name="product.info.example"  as="example" template="example/view.phtml" />

I am using Magento Enterprise 1.10.1.1 and need to get some dynamic content on our product pages. I am inserting the current time in a block to quickly see if it is working, but can't seem to get through full page cache.

I have tried a variety of implementations found here:

cache.xml 中的 必须与布局中的块全名匹配,而不是别名,例如 product.info.example

另外,_getIdentifier() 未在 Enterprise_PageCache_Model_Container_Abstract 上实现,只需将其从您返回的字符串中删除即可_getCacheId()
如果您需要添加一些变体,请实现 _getIdentifier() 以返回会话 ID 或您需要的任何内容。

The <name> in the cache.xml must match your blocks full name in the layout, not the alias, e.g. <name>product.info.example</name>

Also, _getIdentifier() isn't implemented on Enterprise_PageCache_Model_Container_Abstract, just remove it from the string returned by your _getCacheId().
If you need to add some variants, implement _getIdentifier() to return a session id or whatever you need.
