Zend Framework 1.10中Captcha元素的自定义错误消息

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'

为什么重复错误以及如何解决？

在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'
      )
    )
  )
);
