在Zend_Form中，如何避免Zend_Validate_Email产生多个错误? [英] In a Zend_Form, how to avoid Zend_Validate_Email from generating multiple errors?

问题描述

我正在构建一个ZendFramework应用程序，该应用程序作为登录表单来询问电子邮件地址和密码-在尝试通过登录尝试访问数据库之前，先验证电子邮件地址似乎很有意义，因为无效的电子邮件永远不会导致有效命中. Zend_Validate_EmailAddress似乎是正确的方法，但是我遇到了一个问题，即它会产生多个错误(在代码后的底部，是问题).

I am building a ZendFramework application which as a login form asking for an email address and password - it seemed to make sense to validate the email address before hitting the database with the login attempt, as an invalid email would never lead to a valid hit. Zend_Validate_EmailAddress seemed like the right way to go, but I am having an issue with it generating multiple errors (question at the bottom, after the code).

我的表单当前具有以下内容

My form currently has the following

//WPMail_Form_Login::init()
$email = $this->addElement('text', 'email', array(
    'label'=>'Email',
    'required'=>true,
    'filters'=>array('stringtrim'),
    'validators'=>array(array('emailaddress', true, array(
        'messages'=>array(
            'emailAddressInvalidHostname'=>'Your email address is invalid',
            'emailAddressInvalidFormat'=>'Your email address is invalid',
            '...'=>'(repeat for all message templates)'
        )
    ))),
));

在控制器中，我将表单直接传递给视图:

In the controller I directly pass the form into the view:

// WPMail_AuthController::loginAction()
$this->view->form = $form;

在视图中，它是直接回显的:

And in the view, it's directly echo'd:

// views/scripts/auth/login.phtml
<?php echo $this->form ?>

目前的结果是这样的:

- Your email address is invalid
- 'asda!!!' does not match the expected structure for a DNS hostname
- 'asda!!!' does not appear to be a valid local network name

我想知道的是:是否可以以仅产生单个电子邮件无效错误的方式配置Zend _ Validate _ EmailAddress?我的意思是配置"，而不是扩展类并用我自己的逻辑覆盖.

What I want want to know is: Is it possible to configure Zend_Validate_EmailAddress in such a way that it only produces a single email-invalid error? By 'configure' I mean, without extending the class and overriding the logic with my own.

TIA.

推荐答案

Zend Form Element具有多种可用于自定义消息的方法.从文档中还不清楚，但是addErrorMessage()会在验证失败时设置一条自定义错误消息.

Zend Form Element has various methods you can use to customise messages . It's not terribly clear from the docs but addErrorMessage() sets a single custom error message on failed validation.

因此，您的示例如下所示:

Your example would therefore look like:

$email = new Zend_Form_Element_Text('email');
$email->setLabel('Email')
      ->setRequired(true)
      ->addFilter('stringtrim')
      ->addValidator('emailAddress', true)
      ->addErrorMessage('Your email address is invalid');
$this->addElement($email);
