Question

我使用了http://www.mahbubblog.com/php/form-validation-callbacks-in-hmvc-in-codeigniter/comment-page-2/#comment-5996中找到的解决方案。它在Mac上的CI 3.0上工作，但是当我尝试将网站部署到我的Ubuntu服务器时，它会生成＆＃34;无法访问与您的字段名称验证码相对应的错误消息。（captchacheck）＆＃34;。请帮忙......

由于

function index(){
  $this->load->library('form_validation');
  $this->form_validation->set_rules('username', 'User Name', 'trim|required|min_length[4]|xss_clean');
  $this->form_validation->set_rules('firstname', 'First Name', 'trim|required|min_length[4]|xss_clean');
  $this->form_validation->set_rules('lastname', 'Last Name', 'trim|required|min_length[4]|xss_clean');
  $this->form_validation->set_rules('email', 'Your Email', 'trim|required|valid_email');
  $this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_length[32]');
  $this->form_validation->set_rules('password2', 'Password Confirmation', 'trim|required|matches[password]');
  $this->form_validation->set_rules('country', 'Country', 'trim|required|min_length[4]|xss_clean');
  $this->form_validation->set_rules('company', 'Company', 'trim|required|min_length[4]|xss_clean');
  $this->form_validation->set_rules('captcha', 'captcha', 'trim|strip_tags|callback_captcha_check|match_captcha[captcha.word]');
  $data = $this->get_data_from_post();
    if ($this->form_validation->run($this) === false){
       $data['image'] = $this->captcha_model->create_image();
       $data['view_file'] = 'registration';
       $data['js']="";
       $data['module'] = 'users';
       $this->load->module('template');
       $this->template->site($data); 
    }
    else{
       $data2 = $this->get_data_from_post();
       $this->db->insert('ict_users',$data2);
       $data['view_file'] = 'success';
       $data['js']="";
       $data['module'] = 'users';
       $this->load->module('template');
       $this->template->site($data); 
    } 
}

function captcha_check($value){
    if($value==''){
        $this->form_validation->set_message('captcha_check','Please enter the text from the image');
        return false;
    }
    else{
        return true;

    }
}

Answer 1

Please remove 
match_captcha[captcha.word]
You need to use a callback for it below given

public function validate_captcha(){
    if($this->input->post('captcha') != $this->session->userdata['captcha'])
    {
        $this->form_validation->set_message('validate_captcha', 'Wrong captcha code, hmm are you the Terminator?');
        return false;
    }else{
        return true;
    }

}

无法访问与您的字段名称验证码对应的错误消息。（captchacheck）
