Zend表单字段映射到DB列

我有一张Zend_表格

$form = new My_Form();
$uploadedData = $form->getValues();
Zend_Debug::dump($uploadedData, $form->name,true)

当我转储表单值时,我得到一个字符串数组

array(11) {
  ["event"] => string(2) "26"
  ["firstname"] => string(3) "sdf"
  ["surname"] => string(0) ""
  ["gender"] => string(1) "M"
  ["company"] => NULL
  ["dateOfBirth"] => string(10) "11-11-1977"
  ["address"] => string(6) "dfasdf"
  ["address2"] => string(4) "adfs"
  ["address3"] => string(4) "adfs"
  ["email"] => string(7) "x@x.com"
  ["mobile"] => string(0) ""
}

该表单的字段数与my DB table相同,DB table def是

DROP TABLE IF EXISTS `registration`;
CREATE TABLE IF NOT EXISTS `registration` (
  `id` int(11) NOT NULL auto_increment,
  `event` int(11) NOT NULL,
  `firstname` varchar(50) NOT NULL,
  `surname` varchar(50) NOT NULL,
  `gender` varchar(5) NOT NULL,
  `dateofbirth` date NOT NULL,
  `address` varchar(50),
  `address2` varchar(50),
  `address3` varchar(50),
  `email` varchar(50) NOT NULL,
  `mobile` varchar(50),
  `company` int(11),
  `sector` int(11),
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

我现在得到一个映射错误,因为DB事件列不能接受字符串,并且 与“出生日期”列相同

if($form->isValid($formData))
{
    $logger->info("valid form");
    $table = new Model_DbTable_Registration();
    ... // apply some custom mapping??
    $table->insert($uploadedData);
    ...    
}

我不想手动创建一个新数组,并通过名称将每个表单字段映射到正确的类型-it 好像很痛。在Zend中有没有更聪明的方法来进行这种映射?
