Question

我正在尝试为codeigniter设置自己的回调消息。但是当我尝试自己制作时，它会显示消息codeigniter one和我的自定义消息。以下是我的错误链接显示的最高错误是我想使用的http://postimg.org/image/v9ilejmnt/

如何让它只显示我的自定义错误消息？

我也使用hmvc，因此我必须在表单验证中添加run（$ this）才能使回调工作。

控制器：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Login extends Controller {

   private $error = array();

   public function __construct() {
      parent::__construct();
      $this->load->library('user');
      $this->load->library('form_validation');
      $this->lang->load('common/login', 'english');
      if($this->session->userdata('user_id')) {
         redirect('dashboard');
      } else {
         return false;
         redirect('login');
      }
   } 

   public function index() {
      $this->form_validation->set_rules('username', 'Username', 'required|min_length[4]|max_length[12]|xss_clean|callback_validate');
      $this->form_validation->set_rules('password', 'Password', 'required|xss_clean');

      if($this->form_validation->run($this) == false) {

         if (array_key_exists('warning', $this->error)) {
            $data['error_warning'] = $this->error['warning'];
         } else {
            $data['error_warning'] = '';
         }

         $data['action'] = site_url('login');

         $this->load->view('common/login', $data);
      } else {
          redirect('dashboard');
      }
   }

   function validate() {
      $username = $this->input->post('username');
      $password = $this->input->post('password');

      if ($this->user->login($username, $password)) {
          return true;
      } else {
         $this->error['warning'] = $this->lang->line('error_login');
         return !$this->error;
      }
   }
}

Answer 1

您忘记为回调设置错误消息。

$this->form_validation->set_message('validate', 'invalid username or password');
return FALSE;

或者你可以做

$this->form_validation->set_message('validate', $this->lang->line('error_login'));
return FALSE;

在您的视图文件中，您显示的是每个字段（CI表单验证消息）以及您自己的<?php echo $error_warning; ?>

的错误

您应该使用以下代码

   function validate() {
      $username = $this->input->post('username');
      $password = $this->input->post('password');

      if ($this->user->login($username, $password)) {
          return true;
      } else {
              $this->form_validation->set_message('validate', $this->lang->line('error_login'));
              return FALSE;
      }

并从视图中删除此块

<?php if ($error_warning) { ?>
  <div class="alert alert-danger"><i class="fa fa-exclamation-circle"></i> <?php echo $error_warning; ?>
  <button type="button" class="close" data-dismiss="alert">&times;</button>
 </div>
<?php } ?>
   }

并删除此

  if (array_key_exists('warning', $this->error)) {
            $data['error_warning'] = $this->error['warning'];
         } else {
            $data['error_warning'] = '';
         }

Answer 2

我今天就把它搞定了。当想要使用两种验证方法时，自定义和表单验证都不能使用回调。

public function index() {
      $this->form_validation->set_rules('username', 'Username', 'required|min_length[4]|max_length[12]');
      $this->form_validation->set_rules('password', 'Password', 'required|xss_clean');

      if($this->form_validation->run($this) == false) {

         $data['title'] = $this->lang->line('heading_title');

         $data['text_heading'] = $this->lang->line('text_heading');

         if (array_key_exists('warning', $this->error)) {
            $data['error_warning'] = $this->error['warning'];
         } else {
            $data['error_warning'] = '';
         }

         $data['action'] = site_url('login');

         $this->load->view('common/login', $data);

      } else {

         if($this->validate()) {

             redirect('dashboard');

            } else {

               $data['title'] = $this->lang->line('heading_title');

               $data['text_heading'] = $this->lang->line('text_heading');

               if (array_key_exists('warning', $this->error)) {
                  $data['error_warning'] = $this->error['warning'];
               } else {
                  $data['error_warning'] = '';
               }

               $data['action'] = site_url('login');

               $this->load->view('common/login', $data);

         }
      }
   }
