Zend框架：從動作助手重定向

Question

這是我的控制器助手：

class Application_Controller_Helper_Test extends Zend_Controller_Action_Helper_Abstract 
{ 
    public function preDispatch() 
    { 
     $this->_helper->redirector->gotoUrl('/index/index'); 
     // ... 
    } 

但有錯誤，我無法修復：如果您想從一個動作助手重定向

Call to a member function gotoUrl() on a non-object

Answer 1

，你必須從助手經紀人中檢索重定向助手。以下片段將重定向到index/index。

$controller = $request->getControllerName(); 
$action = $request->getActionName(); 

// Prevent redirection loop 
if ($controller.'/'.$action !== 'index/index') { 
    $redirector = Zend_Controller_Action_HelperBroker::getStaticHelper('Redirector'); 
    $redirector->gotoSimpleAndExit('index', 'index', 'default'); 
} 

Answer 2

$this->_redirector = $this->_helper->getHelper('Redirector'); 

$this->redirector('targetAction', 'targetController');
