Zend 验证器的一条错误消息而不是几条

Question

我有下一个元素：

$email = new Zend_Form_Element_Text('email');
$email->setAttribs(array('class' => 'input-text', 'id' => 'email'))
        ->setLabel($this->view->translate('Email'))
        ->setValue(null)
        ->setRequired(true)
        ->addValidator(new Zend_Validate_EmailAddress())
        ->setDecorators($emailMessageDecorators);

如果电子邮件地址中存在多个错误，则会显示一些错误。像这样：

'fff.fgdf' is no valid hostname for email address '[email protected]'
'fff.fgdf' appears to be a DNS hostname but cannot match TLD against known list
'fff.fgdf' appears to be a local network name but local network names are not allowed

我怎样才能只设置1条消息？我尝试过 setMessage(string)，但它显​​示 3 个相同的错误。谢谢。对不起我的英语。和平与爱）

Answer 1

在过去，我必须为此创建一个自定义验证器：

/**
 * The standard email address validator with a single, simple message
 */
class App_Validate_EmailAddressSimpleMessage extends Zend_Validate_EmailAddress
{
    const COMMON_MESSAGE = 'Invalid email address';

    protected $_messageTemplates = array(
        self::INVALID            => self::COMMON_MESSAGE,
        self::INVALID_FORMAT     => self::COMMON_MESSAGE,
        self::INVALID_HOSTNAME   => self::COMMON_MESSAGE,
        self::INVALID_MX_RECORD  => self::COMMON_MESSAGE,
        self::INVALID_SEGMENT    => self::COMMON_MESSAGE,
        self::DOT_ATOM           => self::COMMON_MESSAGE,
        self::QUOTED_STRING      => self::COMMON_MESSAGE,
        self::INVALID_LOCAL_PART => self::COMMON_MESSAGE,
        self::LENGTH_EXCEEDED    => self::COMMON_MESSAGE,
    );

}

然后使用以下调用：

$email->addValidator(new App_Validate_EmailAddressSimpleMessage());

如果您只想使用与平常相同的语法：

$email->addValidator('EmailAddress');

但让它使用此验证器，那么您可以更改类名/文件名EmailAddressSimpleMessage 简单地 EmailAddress 并使用表单/元素注册前缀 App_Validate_。

更好的可能是允许此类接受您想要的消息的可选构造函数参数，但当时我的做法又快又脏。

如果我没记错的话，您可以调用 setErrorMessages() 在表单元素上设置单个错误消息，而不是在每个单独的验证器上调用 setMessages() ：

$form->addElement('password', 'password', array(
    'label' => 'New password:',
    'required' => true,
    'validators' => array(
        array('StringLength', false, 6),
        // more validators
    ),
    'errorMessages' => array('Invalid password.')
));

Answer 3

这是一个例子（我希望它有帮助）：

$email = new Zend_Form_Element_Text('emailid');

$email->setLabel("Email-Adress :* ")
      ->setOptions(array('size' => 20))
      ->setRequired(true)
      ->addFilter('StripTags')
      ->addFilter('StringTrim')
      ->addValidator('EmailAddress')
      ->getValidator('EmailAddress')->setMessage("Please enter a valid e-mail address.");

Answer 4

这是答案，通过使用 $breakChainOnFailure = true:

addValidator($nameOrValidator, $breakChainOnFailure = false, array $options = null);

Answer 5

您使用这个例子：

$email_validator = new Zend_Validate_EmailAddress();
$email = new Zend_Form_Element_Text('email');
$email->setRequired('true')
      ->setLabel('Email: ')
      ->setDecorators(array(array('ViewHelper'), array('Errors')))
      ->addValidator($email_validator);
