Hi all, im having a bit of trouble retrieving data from a database. I was wondering if somebody could point out where im going wrong. Its for user authentication system, and i know there are pre built systems out there, but i thought id have a go myself first.
the error im getting in my view is:
Code:
A PHP Error was encountered
Severity: Notice
Message: Trying to get property of non-object
Filename: controllers/site.php
Line Number: 24
A PHP Error was encountered
Severity: Notice

Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /home/richard/webroot/CRUD/system/libraries/Exceptions.php:164)
Filename: libraries/Session.php
Line Number: 662
my controller:
Code:
<?php
class Site extends Controller {
function index() {
$this->load->view('site_view');
}
function login() {
$this->form_validation->set_rules('username','User Name', 'required');
$this->form_validation->set_rules('password','Password','required');
$data = array (
'userName' => $this->input->post('username'),
'userPass' => $this->input->post('password')
);
if ($this->form_validation->run() == FALSE) {
$this->index();
}
else {
$res = $this->user_model->checklog($data);
if ($res != 0) {
$this->session->set_userdata(array('loggedIn' => TRUE, 'userId' => $res->id, 'userName' => $res->userName));
$this->secure();
}
else {
$err = array (
'error' => "The entered credentials were incorrect"
);
$this->load->view('site_view', $err);
}
}
}
function secure() {
$data = array (
'uName' => $this->session->userdata('userName')
);
$this->load->view('secure_page', $data);
}
}
and my model if it will help:
Code:
<?php
class User_model extends Model {
function checklog($data) {
$res = $this->db->query("SELECT * FROM users WHERE userName = '".$data['userName']."' AND userPass ='". $data['userPass']."'");
if ($res->num_rows() != 0)
{
return $res->result();
}
else
{
return 0;
}
}
}
any help would be appreciated.
thanks
