向 Zend 框架中的表单元素添加正则表达式验证器 [英] Add a regex validator to a form element in the Zend Framework

问题描述

我在 zend Framework 中创建了一个 Form 类.

I created a Form class in zend Framework.

类 Application_Form_UserSignup 扩展 Zend_Form{

class Application_Form_UserSignup extends Zend_Form {

public function init()
{
    // Set the method for the display form to POST
    $this->setMethod('post');

    // Add an Firstname element
    $this->addElement('text', 'firstname', array(
                              'label'      => 'Your first name:',
                              'required'   => true,
                  'validators' => array('regex', false, array(
                'pattern'   => '/[^<>]/i',
                'messages'  =>  'Your first name cannot contain those characters : < >'))
    ));
    }

}

我想用我自己的正则表达式使用 Zend_Validate_Regex 验证器来验证它.

I would like to validate it with my own regex using the Zend_Validate_Regex validator.

语法中一定有错误，因为我收到此错误但我无法弄清楚.

There must be an error in the syntax because I get this error but I cannot figure it out.

错误是:

消息:传递给 addValidators() 的验证器无效堆栈跟踪:

推荐答案

它的 addValidatorS(多个验证器):

Its addValidatorS (multiple validators):

$this->addElement('text', 'firstname', array(
                          'label'      => 'Your first name:',
                          'required'   => true,
              'validators' => array(
                  array('regex', false, array(
                  'pattern'   => '/[^<>]/i',
                  'messages'  =>  'Your first name cannot contain those characters : < >'))
              )
));
