magento根据条件不起作用删除cookie弹出块

Question

我必须根据条件来删除magento的cookie限制弹出块。

ie）如果Condition为true，则应显示该块，否则不显示。

我在CookieNotice.php中尝试过如下，但如果不满足条件，我无法获取如何删除整个块。

\应用\代码\核心\法师\页\块\ HTML \ CookieNotice.php

class Mage_Page_Block_Html_CookieNotice extends Mage_Core_Block_Template
{
public function getCookieRestrictionBlockContent()
{
    $remoteAddr = Mage::helper('core/http')->getRemoteAddr(true); 
   $info = geoip_record_by_name($remoteAddr);
   $countrycode = $info['country_code'];  //IN

   $allowed = Mage::getStoreConfig('general/country/eu_countries'); //AT,BE,BG,CY,CZ,DK,EE,FI,FR,DE,GR,HU,IE,IT,LV,LT,LU,MT,NL,PL,PT,RO,SK,SI,ES,SE,GB

   if(in_array($countrycode, $allowed)){
        echo 'match found';

        $blockIdentifier = Mage::helper('core/cookie')->getCookieRestrictionNoticeCmsBlockIdentifier();
        $block = Mage::getModel('cms/block')->load($blockIdentifier, 'identifier');
        $html = '';
        if ($block->getIsActive()) {
            /* @var $helper Mage_Cms_Helper_Data */
            $helper = Mage::helper('cms');
            $processor = $helper->getBlockTemplateProcessor();
            $html = $processor->filter($block->getContent());
        }
        return $html;
   }
   else{
        // Here still the pop block appears
         echo 'No match found';
     }

   }
}
