Question

我有一个简单的联系表单，其中包含几个必填字段，工作正常。我正在尝试将reCaptcha添加到表单中以获得一些额外的垃圾邮件保护。

我正确地在表单上显示了reCaptcha，我已经安装了我的密钥。在我的控制器中，我可以调用recaptcha_check_answer方法并获得有效的响应。我已经正确安装和配置了所有文件，因为我可以使用recaptcha类中的方法并获得良好的响应。

我的问题是我想要一个无效的reCaptcha触发器CI form_validation错误，但我花了很多时间在这上面并且无法触发它。我对CI很陌生，所以如果这很容易，请原谅我的无知。

当is_valid响应返回NULL时，我尝试抛出form_validation错误。如果为NULL，那么我尝试执行以下操作：

$this->form_validation->set_message('recaptcha_response_field', 'reCaptcha', lang('recaptcha_incorrect_response'));
echo form_error('recaptcha_response_field');

以下是有效和无效验证码的reCaptcha API响应：

Valid = stdClass Object ( [0] => is_valid [1] => error [is_valid] => 1 )
Invalid = stdClass Object ( [0] => is_valid [1] => error [is_valid] => [error] => incorrect-captcha-sol )

以下是我在Controller中的代码：

class Contact extends CI_Controller 
{

function __construct()
{
  parent::__construct();
}

public function index()
{
  $this->load->library('recaptcha');
  $this->recaptcha->set_key ('MY_PUBLIC_KEY_HERE' ,'public');
  $this->recaptcha->set_key ('MY_PRIVATE_KEY_HERE' ,'private'); // For private key

     // Is this a Form Submission?
     if (!empty($_POST))
     {

        // LOAD VALIDATION AND SET RULES
         $this->load->library('form_validation');
         $this->load->helper('form');


        $this->form_validation->set_rules('first_name', 'First Name', 'required');
        $this->form_validation->set_rules('last_name', 'Last Name', 'required');
        $this->form_validation->set_rules('email', 'Email', 'required|valid_email');
        $this->form_validation->set_rules('recaptcha_response_field', 'reCaptcha', 'required|recaptcha_check_answer');
        $this->_resp = $this->recaptcha->recaptcha_check_answer ( $this->input->ip_address(), $this->input->post('recaptcha_challenge_field',true), $this->input->post('recaptcha_response_field',true));

        // If the reCaptcha doesnt match throw an form_valiation Error
        if ($this->_resp->is_valid == '')
        {
            $this->form_validation->set_message('recaptcha_response_field', 'reCaptcha', lang('recaptcha_incorrect_response'));
            echo form_error('recaptcha_response_field');
        }



        if ($this->form_validation->run() !== FALSE)
        {
           // SUCCESS NO ERRORS - SEND EMAIL DATA AND RETURN TO HOME
              $this->load->library('email');   // LOAD EMAIL LIBRARY
              $config['protocol'] = 'sendmail';
              $config['mailpath'] = '/usr/sbin/sendmail';
              $config['charset'] = 'utf-8';
              $config['wordwrap'] = TRUE;

              $this->email->initialize($config);

              $this->email->from($this->input->post('email'), $this->input->post('first_name').' '.$this->input->post('last_name'));
              $this->email->to('jassen.michaels@gmail.com');
              $this->email->cc('');
              $this->email->bcc('');

              $this->email->subject('Contact Email From Spider Design Website');
              $this->email->message(
                    'First Name: '.$this->input->post('first_name')."\r\n".
                    'Last Name: '.$this->input->post('last_name')."\r\n".
                    'Company: '.$this->input->post('company')."\r\n".
                    'Location: '.$this->input->post('location')."\r\n"."\r\n".
                    'I am interested in learning: '."\r\n"."\r\n".
                    'Information Architecture: '.$this->input->post('information_architecture')."\r\n".
                    'Web Design: '.$this->input->post('web_design')."\r\n".
                    'Graphic Design: '.$this->input->post('graphic_design')."\r\n".
                    'Email Marketing: '.$this->input->post('email_marketing')."\r\n".
                    'Social Media: '.$this->input->post('social_media')."\r\n".
                    'Content Management: '.$this->input->post('content_management')."\r\n".
                    'Search Engine Optimization: '.$this->input->post('seo')."\r\n".
                    'Web Traffic Analytics: '.$this->input->post('wta')."\r\n"."\r\n".
                    'Preferred Method of Contact: '."\r\n".
                    'Phone: '.$this->input->post('phone')."\r\n".
                    'Email: '.$this->input->post('email')."\r\n"."\r\n".
                    'Comments: '."\r\n".
                    $this->input->post('comments')            
                    );

           //$this->email->send();
           //$this->load->helper('url');
           //redirect('http://sdi.myspiderdesign.com/fuel');
        } 
     }

         // Not a form submission, load view
         $this->load->helper('form');
         $this->load->view('include/spider_header');
         $this->load->view('contact');   // Content Area
         $this->load->view('include/spider_footer'); // Footer
   }
}

我已在表单底部注释了重定向和联系电子邮件，直到我可以解决此问题。

提前感谢您的帮助！

我在form_validation库中使用了callback_函数。在进行API调用的控制器内部设置一个额外的函数，如果验证码没有通过，则会抛出validation_error。

CodeIgniter reCaptcha和Form_validation类
