Question

我使用codeigniter创建了一个简单的登录申请表。我的问题是当我在浏览器中访问时，不会加载login_view文件。

登录视图：（application / views / login_view.php）

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
 <head>
   <title>Simple Login with CodeIgniter</title>
 </head>
 <body>
   <h1>Simple Login with CodeIgniter</h1>
   <?php echo validation_errors(); ?>
   <?php echo form_open('verifylogin'); ?>
     <label for="username">Username:</label>
     <input type="text" size="20" id="username" name="username"/>
     <br/>
     <label for="password">Password:</label>
     <input type="password" size="20" id="passowrd" name="password"/>
     <br/>
     <input type="submit" value="Login"/>
   </form>
 </body>
</html>

登录控制器（application / controllers / login.php）

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

class Login extends CI_Controller {

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

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

}

?>

VerifyLogin Controller（application / controllers / verifylogin.php）

class VerifyLogin extends CI_Controller {

 function __construct()
 {
   parent::__construct();
   $this->load->model('user','',TRUE);
 }

 function index()
 {
   //This method will have the credentials validation
   $this->load->library('form_validation');

   $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
   $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');

   if($this->form_validation->run() == FALSE)
   {
     //Field validation failed.  User redirected to login page
     $this->load->view('login_view');
   }
   else
   {
     //Go to private area
     redirect('home', 'refresh');
   }

 }

 function check_database($password)
 {
   //Field validation succeeded.  Validate against database
   $username = $this->input->post('username');

   //query the database
   $result = $this->user->login($username, $password);

   if($result)
   {
     $sess_array = array();
     foreach($result as $row)
     {
       $sess_array = array(
         'id' => $row->id,
         'username' => $row->username
       );
       $this->session->set_userdata('logged_in', $sess_array);
     }
     return TRUE;
   }
   else
   {
     $this->form_validation->set_message('check_database', 'Invalid username or password');
     return false;
   }
 }
}
?>
