找不到对象！ 在Codeigniter登录

Question

I'm new to Codeigniter and I'm trying to build a login form by following some tutorials. However, when I try to submit the login form in order to validate the credentials that have been inputted by calling the validate_login function in the login controller , I get the "Object not Found" Error. Every time I click my submit button, my URL redirects to "http://localhost/pgevCI/login/validate_login", but it still gets the Object not Found error.

Controller: login.php

<?php

class Login extends CI_Controller {

    function index()
    {
        $data['main_content'] = 'view_login';
        $this->load->view('includes/login_template', $data);    
    }
function validate_login()
    {
        $this->load->model('model_accounts');
        $valid = $this->model_accounts->validate();

        if($valid)
        {
            $data = array(
                'userid' => $this->input->post('userid'),
                'is_logged_in' => true
            );

            $this->session->set_userdata($data); 
            redirect('site/admin');
        }

        else
        {
            $this->index();
        }       
      }
    }

View form: view_login.php

<form action="<?php echo base_url(); ?>login/validate_login" method="POST">
    <div class="row">
      <div class="col-lg-6">
        <div class="form-group">
          <input type="text" name="userid" class="form-control" id="user-name" aria-label="..." placeholder="Enter your username">
        </div><!-- /input-group -->
      </div><!-- /.col-lg-6 -->

      <div class="col-lg-6">
        <div class="form-group">
          <input type="password" name="password" class="form-control" id="user-password" aria-label="..." placeholder="Enter your password">
        </div><!-- /input-group -->
      </div><!-- /.col-lg-6 -->
    </div><!-- /.row -->

    </br>
    </br>
    <!-- Standard button -->
    <div class="action-buttons text-center">

      <button type="submit" class="btn btn-custom">Sign In</button>

      <button type="button" class="btn btn-custom">Forgot your password?</button>

    </div>
  </form>

Model: model_accounts.php

class Model_accounts extends CI_Model {

    function validate() 
    {

        $this->db->where('userid', $this->input->post('userid'));
        $this->db->where('password', md5($this->input->post('password')));
        $query = $this->db->get('users');

        if($query->num_rows == 1)
        {

            return true;    
        }
    }
}

Base URL & Index File :

$config['base_url'] = 'http://localhost/pgevCI/';
$config['index_page'] = 'index.php';

Error Page

Any help would really be appreciated! :)

Answer 1

You have to use

<?php echo site_url('login/validate_login') ?>

instead of

<?php echo base_url(); ?>login/validate_login

You haven't set CI to use nice URLs, so your real redirect url is

http://localhost/pgevCI/index.php/login/validate_login

You have to set

$config['index_page'] = '';

and use a htaccess if you want the urls to appear like

http://localhost/pgevCI/login/validate_login
