html - 我的Google验证码代码无法正常工作

我想在我的注册页面中提供验证码代码的安全性，但是当我用错误的验证码代码填写表单并提交表单时。问题是在我的注册页面中查看两页。并再次使用正确的验证码填写此表格，但是他们又遇到了同样的问题，并显示了错误的验证码。

控制器

public function user_signup($data = NULL){
                $this->load->library('form_validation');
                $this->recaptcha->recaptcha_check_answer($_SERVER['REMOTE_ADDR'],$this->input->post('recaptcha_challenge_field'),$this->input->post('recaptcha_response_field'));

                $this->form_validation->set_rules('Username', 'Username', 'required|trim|is_unique[users.Username]');
                $this->form_validation->set_rules('First_name', 'First Name', 'required|trim');
                $this->form_validation->set_rules('Last_name', 'Last Name', 'required|trim');
                $this->form_validation->set_rules('Email', 'Email', 'required|trim|valid_email');
                $this->form_validation->set_rules('Password', 'Password', 'required|trim|md5');
                $this->form_validation->set_rules('Conf_password', 'Confirm Password', 'required|trim|matches[Password]');
                $this->form_validation->set_message('is_unique', 'Username already exists.');
                if($this->form_validation->run() && $this->recaptcha->getIsValid()){
                    //Call to recaptcha to get the data validation set within the class.

                    $form_data = array();
                        $form_data['Username'] = $this->input->post('Username');
                        $form_data['First_name'] = $this->input->post('First_name');
                        $form_data['Last_name'] = $this->input->post('Last_name');
                        $form_data['Email'] = $this->input->post('Email');
                        $form_data['Password'] = $this->input->post('Password');
                        $form_data['Conf_password'] = $this->input->post('Conf_password');

                        $this->load->model('User');
                        $this->User->sign_up($form_data);
                        $data['msg']= "Account Created Sucessfuly";

                       }else{
                        if(!$this->recaptcha->getIsValid()){
                        $this->session->set_flashdata('error','incorrect captcha');
                        }
                    }

                redirect("Users/signup", $data);
        }

模型

public function sign_up($form_data){
       $this->db->insert('users', $form_data);
}

最佳答案

将此代码放在if（！$ this-> recaptcha-> ​​getIsValid（））{之后，然后回显消息...

    if($this->input->post('recaptcha_response_field') =="" ){
         $this->session->set_flashdata('error','fill up this code');
    }else{
         $this->session->set_flashdata('error','incorrect captcha');
    }

如果您显示消息“帐户创建成功”。使用设定的即显信息
