Just a starter in CI. I already have my registration function working but I'm having a difficulty in in my login function. I played with using CI Forms then switched to typical HTML input forms. Below are my MVC codes.
EDIT: Result will only show white screen.
Server: XAMPP
CI v3.1.6
Controller:
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Users extends CI_Controller {
function __construct()
{ //load the needed libraries and classes
parent::__construct();
$this->load->library('form_validation');
$this->load->model('User');
}
//function for account checking
public function account()
{
//check if the user is login or not
$data = array();
if($this->session->userdata('isUserLoggedIn'))
{//if true the user will be redirected to userview page
$data['User'] = $this->User->getRows(array('id' =>$this->session->userdata(userId)));
$this->load->view('userview',$data);
}
else
{ //user will be redirected to registration form
redirect('register');
}
}//function to do login
public function login()
{
$data = array();
if($this->session->userdata('success_msg'))
{
$data['success_msg'] = $this->session->userdata('success_msg');
$this->session->unset_userdata('success_msg');
}
if($this->input->post('loginSubmit')) //submit name for the button
{ //validate the submitted input
$this->form_validation->set_rules('username','username','required|max_length[20]|min_length[5]');
$this->form_validation->set_rules('password','password','required|max_length[20]|min_length[8]');
if($this->form_validation->run())
{
$con['returntype'] = 'single';
$con['conditions'] = array (
'username' => $this->input->post('username'),
'password' => $this->input->post('password')
);
$checkLogin = $this->User->getRows($con);
if($checkLogin)
{
$this->session->set_userdata('isUserLoggedIn,TRUE');
$this->session->set_userdata('userID',$checkLogin['username']);
$this->session->set_flashdata('Logged_success','Welcome!');
redirect(base_url(),'userview');
}
else
{
$this->session->set_flashdata('LogF','Login failed! Check your credentials.');
redirect(base_url(),'home');
}
}
}
}
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

Code:

<p class="alert alert-dismissable alert-danger"><?php echo $this->session->flashdata('username1'); ?></p>
<?php endif; ?>
<form action="<?php base_url(); ?>Users/login" method="post">
