Zend Form 验证所需元素

我的 Zend Form 中有所需的元素：

$name = new Zend_Form_Element_Text('name');
$name->setLabel('Name')
   ->setValue(isset($plan)?$plan['name']:'')
   ->setRequired()
   ->setAttribs(array('class' => 'required', 'maxlength' => 50))
   ->addValidators(array(new Zend_Validate_StringLength(array('min' => 1, 'max' => 50)),
      new Zend_Validate_Db_NoRecordExists(array('table' => 'plan', 'field' => 'name')))
   ->addFilters(array(new Zend_Filter_StringTrim, new Zend_Filter_StripTags));

所有验证器都工作完美。但这是一个问题。在控制器中，我使用 getValidValues 检查表单（这对我来说是必需的）。如果数据库中的记录存在，则元素无效，Zend 清除该元素。我接受了“需要价值”的信息。如何获取有关数据库中现有行的消息？
抱歉我的英语。先感谢您。

I have the required element in my Zend Form:

$name = new Zend_Form_Element_Text('name');
$name->setLabel('Name')
   ->setValue(isset($plan)?$plan['name']:'')
   ->setRequired()
   ->setAttribs(array('class' => 'required', 'maxlength' => 50))
   ->addValidators(array(new Zend_Validate_StringLength(array('min' => 1, 'max' => 50)),
      new Zend_Validate_Db_NoRecordExists(array('table' => 'plan', 'field' => 'name')))
   ->addFilters(array(new Zend_Filter_StringTrim, new Zend_Filter_StripTags));

All validators work perfect. But it is one problem. In controller I check form using getValidValues (it is required for me). And if Record in DB is exist, element is invalid and Zend clear this element. And I take the message 'Value is required'. How can I get message about existing of row in DB?
Sorry for my english. Thank you in advance.
