我在 magento 1.7.0.2 中添加了新模块，一切正常。我单击添加到购物车无法显示成功消息，但产品在我的购物车中是正常的。当我单击另一个页面时，会出现消息。

class HB_Printer_FinderController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()
    {
        $this->_title($this->__('Products Finder'));     
        $this->loadLayout();     
        $this->renderLayout();

    }

    public function resultAction()
    {
        $this->_title($this->__('Printer Applicable Products'));
        $this->loadLayout();     
        $this->renderLayout();
    }
}

为什么不在当前页面显示消息。如何解决？

您应该通过 Mage_Core_Controller_Varien_Action::_initLayoutMessages() 初始化所需的布局消息

例子：

public function resultAction()
{
    $this->_title($this->__('Printer Applicable Products'));
    $this
        ->loadLayout()
        ->_initLayoutMessages('checkout/session')
        ->_initLayoutMessages('catalog/session')
    $this->renderLayout();
}

您需要初始化一个包含所需消息的会话模型。

还要记住，printer/finder/result.phtml应该包含

$this->getMessagesBlock()->getGroupedHtml()
