Magento 消息提示

//成功
Mage::getSingleton('customer/session')->addSuccess('恭喜您关联会员卡成功！');
//失败
Mage::getSingleton('customer/session')->addError($e->getMessage());
//一般消息
Mage::getSingleton('customer/session')->addNotice('合并发货单规则');

错误处理 controller不支持redirect跳转

if($this->getRequest()->isPost()){
    try {
		$methodList = Mage::helper('recharge')->getRechargeMethodList();
		$method = $this->getRequest()->getPost('method','');
		$points = floatval($this->getRequest()->getPost('points',0));
		if($points <= 0){
			throw new exception('充值金额不能小于等于0');  //1错误异常
		}
		if('' == $method || !array_key_exists($method,$methodList)){
			throw new exception('充值方式选择错误');
		}
		$methodInstance = Mage::helper('recharge')->getMethodInstance($method);
		if (!$methodInstance) {
			throw new exception('初始化充值错误');
		}
		Mage::getSingleton('customer/session')->addSuccess('恭喜您关联会员卡成功！');
    }catch (exception $e){
		Mage::getSingleton('customer/session')->addError($e->getMessage());//2添加错误
    }
}
$this->loadLayout();
$this->_initLayoutMessages('customer/session'); //3.回显错误layout加
$this->renderLayout();

phtml中添加
