Answer 1

Hope this will help you :
Your controller should be like this :
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Login extends CI_Controller {
public function __construct(){
parent::__construct();
//$this->load->model('User');
$this->load->helper('form');
$this->load->library('form_validation');
$this->load->helper('url');
$this->load->database();
$this->load->model('U_Model');
}
public function index(){
$this->load->view('header');
$this->load->view('login');
$this->load->view('footer');
}
/*added public before loginp*/
public function loginp(){
$username = $this->input->post('username');
$password = md5($this->input->post('password'));
/*md5 not recommended*/
$data = $this->U_Model->loginf($username, $password);
if( ! empty($data))
{
$this->session->set_userdata('sid',$data['id']);
$this->session->set_userdata('sname',$data['name']);
$this->session->set_userdata('username',$data['username']);
redirect('login/home');
}else{
$this->session->set_flashdata('emsg','Please Enter Your Correct Name And Password');
redirect('login/home');
}
}
public function home(){
$this->load->view('home');
}
}?>
Change your model like this
<?php
class U_Model extends CI_Model
{
public function loginf($username,$pass)
{
$this->db->where('username',$username);
$this->db->where('password',$pass);
$query = $this->db->get('users')
if($query->num_rows() > 0){
return $query->row_array();
}else{
return false;
}
}
}
?>

Answer 2

<?php
class U_Model extends CI_Model
{
public function loginf($username,$pass)
{
$this->db->where('username',$username);
$this->db->where('password',$pass);
$query = $this->db->get('users')
if($query->num_rows() > 0){
return $query->row_array();
}else{
return false;
}
}
}
?>
