Php 在客户注销时删除Magento Cookie不工作

我正在使用一个观察者和这个钩子

controller\u action\u postspatch\u customer\u account\u logout

在客户注销时，我希望删除所有设置的cookie，但由于某些原因，它们在客户注销后仍然存在，我确定代码正确吗？有什么想法吗

public function deleteCookies(){
    $cookies = Mage::getModel('core/cookie')->get();

    foreach($cookies as $cookie) {
        $name = Mage::getModel('core/cookie')->get($cookie);
        $path = Mage::getModel('core/cookie')->getPath($cookie);
        $lifetime = Mage::getModel('core/cookie')->getLifetime($cookie);

        Mage::getModel('core/cookie')->delete($name, $path, $lifetime);
    }
}

delete

函数的第三个参数不是cookie的生存期

public function delete($name, $path = null, $domain = null, $secure = null, $httponly = null)

试试这个：

public function deleteCookies(){
    $cookies = Mage::getSingleton('core/cookie')->get();

    foreach($cookies as $cookieName) {
        Mage::getSingleton('core/cookie')->delete($cookieName);
    }
}

希望有帮助
