codeigniter bootstrap登录表单问题

Question

I've been doing this for a while to no avail. I'm having an issue with codeigniter bootstrap login. So basically this is what I have:

login.php - controller

 <?php if (!defined('BASEPATH')) die();
 class Login extends Main_Controller {

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

 public function index()
 { 
  $this->load->view('include/header');
  $this->load->view('login_view');
  $this->load->view('include/footer');
 }

 public function process(){
    // Load the model
    $this->load->model('login_model');
    // Validate the user can login
    $result = $this->login_model->validate();
    // Now we verify the result
    if(! $result){
        // If user did not validate, then show them login page again
        $this->index();
    }else{
        // If user did validate, 
        // Send them to members area
        redirect('home');
    }        
}

}

login_view.php - view

<div class="container">
  <form class="form-signin" action="<?php echo base_url('login/process');?>" method="post" id="loginForm">
    <h2 class="form-signin-heading"><img src="<?php echo base_url('assets/img/hms_icon.png'); ?>" />User Login</h2>
    <input type="text" class="input-block-level" placeholder="Username" name="username" id="username">
    <input type="password" class="input-block-level" placeholder="Password" name="password" id="password">
    <button class="btn btn-large btn-primary" type="submit" name="login" id="login">Sign in</button> 

    <div id="report"></div>
  </form>
 </div> <!-- /container -->

login_model.php - model

  <?php
 Class Login_model extends CI_Model
{

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

public function validate(){
    // grab user input
    $username = $this->security->xss_clean($this->input->post('username'));
    $password = $this->security->xss_clean($this->input->post('password'));

    // Prep the query
    $this->db->where('username', $username);
    $this->db->where('password', $password);

    // Run the query
    $query = $this->db->get('users');
    // Let's check if there are any results
    if($query->num_rows == 1)
    {
        // If there is a user, then create session data
        $row = $query->row();
        $data = array(
                '_id' => $row->userid,
                'username' => $row->username,
                'validated' => true
                );
        $this->session->set_userdata($data);
        return true;
    }
    // If the previous process did not validate
    // then return false.
    return false;
 }
 }
?>

I get an error in

 <?php echo base_url('login/process');?>

Object is not found. What am I missing in here? Any help is much appreciated.

Answer 1

Try replacing

<?php echo base_url('login/process');?>

with just

'/login/process'

Don't forget the leading slash. This is just a guess, because we don't have enough informations provided about your settings.

EDIT::

NOTE: Read my comment first.

First in your autoload.php load session library. Then modify your process() function in controller like this:

public function process(){
   $this->load->model('login_model');
   $result = $this->login_model->validate();
   if(! $result){
       $this->index();
   }else{
      $data = array(
          'username'    => $this->input->post('username'),
          'is_logged_in'    => true
   );

   $this->session->set_userdata($data);
   redirect('home');
}

Then in your home.php controller:

function __construct()
    {
        parent::Controller();
        $this->is_logged_in();
        }

function is_logged_in()
    {
        $is_logged_in = $this->session->userdata('is_logged_in');

        if(!isset($is_logged_in) || $is_logged_in != true)
        {
            redirect('login');
        }
    }

You need to set the session so the member area knows that user is logged in. You can manage session length and other properties in config.php.

Let me know if it helped.
