Have you ever wanted to enable Magento global messages when you have Full Page Cache (FPC) turned on ? I wanted it, but after several hours of debugging and studying magento caching mechanism, i found it’s hard to punch a hole for Magento global message, i thought about an alternative solution – ignoring FPC when we have global message !<\/p>\n

<\/p>\n

By default, when we add this GET parameter ‘?___store’ to request url, Magento will bypass caching and generate content from files, sessions and database for you. With this clue, we know what we need to do is to add ‘?___store’ parameter to redirect url so we can achieve our goal<\/p>\n

In order to do that, you will need to override a controller that you want to display global message after have action in that controller done.<\/p>\n

\n<frontend>\n     <routers>\n          <catalog>\n               <args>\n                    <modules>\n                         <Wagento_Custom before="Mage_Catalog">Wagento_Custom<\/Wagento_Custom>\n                    <\/modules>\n               <\/args>\n          <\/catalog>\n     <\/routers>\n<\/frontend>\n<\/pre>\n
Then you need to modify _redirectReferer function extended from Mage_Core_Controller_Varien_Action like this<\/p>\n
\n<?php\n\/*include Mage_Catalog_Product_CompareController to extend it*\/\nrequire_once 'Mage\/Catalog\/controllers\/Product\/CompareController.php';\n\nclass Wagento_Custom_Product_CompareController extends Mage_Catalog_Product_CompareController\n{\n     protected function _redirectReferer()\n     {\n        $refererUrl = $this->_getRefererUrl();\n        if (empty($refererUrl)) {\n            $refererUrl = empty($defaultUrl) ? Mage::getBaseUrl() : $defaultUrl;\n        }\n\n          \/*inject ignore global full page cache param*\/\n          if (!strpos($refererUrl, '?___store'))\n          {\n               $refererUrl .= '?___store';\n          }\n          \/*end of hacking*\/\n\n        $this->getResponse()->setRedirect($refererUrl);\n          \/\/parent::_redirectReferer($url); \/\/ call _redirectReferer from Mage_Core_Controller_Varien_Action\n        return $this;\n     }\n}\n<\/pre>\n
that’s it, we’ve done it in dirty<\/em><\/strong> way<\/p>\n","protected":false},"excerpt":{"rendered":"
