Zend framework2 zend表单ZF2中的排除值

如何排除您在$\u POST中收到的数据？ 此表单用于修改用户数据： 表格必须验证电子邮件是否不存在，该电子邮件是否属于她，并且已经记录：

public function __construct(Adapter $adapter)
{
    $no_record_exists = new NoRecordExists(array(
        'table'   => 'user',
        'field'   => 'email',
        'adapter' => $adapter,
        'exclude' => array(
            'field' => 'email',
            'value' => '$_POST['email']'
        )  
    ));       
    $this->add(array(
        'name' => 'email',
        'required' => true,
        'filters' => array(
            array(
                'name' => 'StripTags'
            ),
            array(
                'name' => 'StringTrim'
            )
        ),
        'validators' => array(
            $no_record_exists,
            array(
                'name' => 'EmailAddress',
                'options' => array(
                    'encoding' => 'UTF-8',
                    'min' => 5,
                    'max' => 48
                )
            ),
        )
    ));
}

这就是我如何包含排除过滤器的方法

    //include unique field validator
    $noRecordExist = new \Zend\Validator\Db\NoRecordExists(
        array(
            'table' => 'user',
            'field' => 'email',
            'adapter' => $adapter,
        )
    );
    $noRecordExist->setMessage('Email already exist');
`   $id = $_POST['id'];
    if($id > 0){
        $noRecordExist->setExclude('email != ' . $_POST['email']);
    }
    //you can add this validator to your filter chain

$id在哪里？此函数用于修改用户，以排除他们的电子邮件。我已编辑答案以初始化$id，假设此答案与表单字段一起从客户端提交，以标识编辑或添加新项目
