php - codeigniter 中的表单验证总是返回 false

Question

我是 codeigniter 的新手，我不明白为什么我的 form_validation 一直返回 false。这是我的代码:

登录 Controller

class Login extends CI_Controller {

     function __construct()
     {
       parent::__construct();
       $this->load->helper(array('form','url'));
       $this->load->library('form_validation');
       $this->load->library('session');
       $this->load->model('user','',TRUE);
     }

     function index()
     {
        $this->load->view('login_view');
     }

     function user_registration_show(){

        $this->load->view('registration_view');

     }

     function user_login_process(){


     }

     function user_registration_process(){

        $this->form_validation->set_rules('fname', 'First Name', 'trim|required|xss_clean');
        $this->form_validation->set_rules('lname', 'Last Name', 'trim|required|xss_clean');
        $this->form_validation->set_rules('gender', 'Gender', 'trim|required|xss_clean');
        $this->form_validation->set_rules('address', 'Address', 'trim|required|xss_clean');
        $this->form_validation->set_rules('emailadd', 'Email Address', 'trim|required|xss_clean');
        $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
        $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean');
        $this->form_validation->set_rules('password1', 'Re-type Password', 'trim|required|xss_clean');
        if ($this->form_validation->run() == FALSE) {
            $this->load->view('registration_view');
        } else {

            $pass = $this->input->post('password');
            $pass1 = $this->input->post('password1');
            if($pass!=$pass1){

                $data['message_display'] = 'Password mismatched!';
            }else{
                $data = array(
                'Fname' => $this->input->post('Fname'),
                'Lname' => $this->input->post('Lname'),
                'Gender' => $this->input->post('Gender'),
                'Address' => $this->input->post('Address'),
                'EmailAdd' => $this->input->post('EmailAdd'),
                'username' => $this->input->post('username'),
                'password' => $this->input->post('password')
                );
            }

        }
     }
}

我正在使用 codeigniter 3.1.3。谁能帮帮我？

由于在所有字段中使用了 xss 干净检查，您的表单验证失败。如果您删除它，它会验证您的字段。因为您的数据已经被 xss 清理(假设 global_xss_filtering 在配置中为 TRUE)
