Zend的形式定製驗證

Question

在我的控制，我有

if(isset($username) && trim($username)!=='') 
{ 
    $exist = $user_obj->checkUsernameExist($username); 
     if($exist == '1') 
     { 
      $form->getElement('username')->addError('This username exists.'); 
     } 
} 
if ($form->isValid($_POST)) { 
$user_obj->insertUser($_POST); 
$this->_helper->flashMessenger->addMessage('User Added Successfully.'); 
$this->_redirect('/users/usersadministration/'); 
exit();  
}else { //echo 'failure'; 
    //print_r($form->getErrors()); 
} 

但不顯示我的錯誤消息，即使的$exist值1

嘗試

if(isset($username) && trim($username)!=='') 
{ 
    $exist = $user_obj->checkUsernameExist($username); 
     if($exist == '1') 
     { 
      $form->getElement('username')->addError('This username exists.'); 
      $form->markAsError(); 
     } 
}
