Question

我正在尝试将自己的自定义错误消息设置到我的Captcha上，但由于某种原因，它会回显两次。

这是我的验证码：

$captcha = new Zend_Form_Element_Captcha(
  'captcha', // This is the name of the input field
  array('captcha' => array(
      // First the type...
      'captcha' => 'Image',
      // Length of the word...
      'wordLen' => 6,
      // Captcha timeout, 5 mins
      'timeout' => 300,
      // What font to use...
      'font' => 'images/captcha/font/arial.ttf',
      // URL to the images
      'imgUrl' => '/images/captcha',
      //alt tag to keep SEO guys happy
      'imgAlt' => "Captcha Image - Please verify you're human"
  )));

然后设置我自己的错误消息：

$captcha->setErrorMessages(array('badCaptcha' => 'My message here'));

验证失败后，我得到：

'My message here; My message here'

为什么要重复错误以及如何解决？

花了很多时间试图让它工作之后，我最终在构造函数的选项中设置了消息

$captcha = new Zend_Form_Element_Captcha(
  'captcha', // This is the name of the input field
  array(
    'captcha' => array(
      // First the type...
      'captcha' => 'Image',
      // Length of the word...
      'wordLen' => 6,
      // Captcha timeout, 5 mins
      'timeout' => 300,
      // What font to use...
      'font' => 'images/captcha/font/arial.ttf',
      // URL to the images
      'imgUrl' => '/images/captcha',
      //alt tag to keep SEO guys happy
      'imgAlt' => "Captcha Image - Please verify you're human",
      //error message
      'messages' => array(
        'badCaptcha' => 'You have entered an invalid value for the captcha'
      )
    )
  )
);

我调查了这个答案，但我并不是非常喜欢这个解决方案，现在我使用输入规范来完成它，如：

public function getInputSpecification()
{
    $spec = parent::getInputSpecification();

    if (isset($spec['validators']) && $spec['validators'][0] instanceof ReCaptcha) {
        /** @var ReCaptcha $validator */
        $validator = $spec['validators'][0];
        $validator->setMessages(array(
            ReCaptcha::MISSING_VALUE => 'Missing captcha fields',
            ReCaptcha::ERR_CAPTCHA => 'Failed to validate captcha',
            ReCaptcha::BAD_CAPTCHA => 'Failed to validate captcha', //this is my custom error message
        ));
    }

    return $spec;
}

我刚注意到，这是ZF1的一个问题

这是ZF2的答案
