这是我的代码:

app/code/local/Fido/Example/Block/View.php

app/code/local/Fido/Example/Block/View.php

<?php class Fido_Example_Block_View extends Mage_Core_Block_Template { private $message; private $att; protected function createMessage($msg) { $this->message = $msg; } public function receiveMessage() { if($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; } }

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

来自 app/design/frontend/enterprise/[mytheme]/layout/catalog.xml 的片段

snippet from app/design/frontend/enterprise/[mytheme]/layout/catalog.xml

<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" />

推荐答案

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

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>

此外，_getIdentifier() 未在 Enterprise_PageCache_Model_Container_Abstract 上实现，只需将其从 _getCacheId() 返回的字符串中删除即可.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.

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.
