zend-framework - zend-framework，从另一个 Action 助手中调用 Action 助手

Question

我正在编写一个 Action 助手，我需要从该助手中调用另一个 Action 助手。但我不知道如何。在示例代码中:

class Common_Controller_Action_Helper_SAMPLE extends Zend_Controller_Action_Helper_Abstract
{
    protected $_view;
    public function __construct(Zend_View_Interface $view = null, array $options = array())
    {
        $this->_view = $view;
    }

    public function preDispatch()
    {
        $flashMessenger = $this->_helper->FlashMessenger; // IT IS NULL
    }
}

Answer 1

使用action helper broker:

$flashMessenger =
    Zend_Controller_Action_HelperBroker::getStaticHelper('FlashMessenger');
