Display the profile information of a logged in user in Codeigniter? - php

Question

I want to create a profile view for the user that is currently logged in. I created a session_data array for when you log in that only contains their username. How would I retrieve the other values from the row depending on who is logged in? Do I have to add all that information to the session_data array?
I have the values first_name, last_name, & date_joined that I want to display alongside username.
Login Controller:
class Login extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->load->view('templates/header');
$this->load->view('login');
$this->load->view('templates/footer');
}
function login_validation()
{
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
if($this->form_validation->run())
{
$username = $this->input->post('username');
$password = $this->input->post('password');
$this->load->model('login_model');
if ($this->login_model->can_login($username, $password))
{
$session_data = array(
'username' => $username
);
$this->session->set_userdata($session_data);
redirect('home');
}
else {
$this->session->set_flashdata('error', 'Invalid Username and Password');
redirect('login');
}
}
else {
$this->index();
}
}
function enter()
{
if ($this->session->userdata('username') != '') {
echo "Welcome " . $this->session->userdata('username');
echo 'Logout';
}
else {
redirect('login');
}
}
function logout()
{
$this->session->unset_userdata('username');
redirect('login');
}
}
User View:
<h4><?php echo $_SESSION['username']; ?></h4>

You'll need a method in login_model that retrieves the username info based on the username you send to it.
Something like this:
function get_user($username)
{
$this->db->select(*);
$this->db->from('users');
$this->db->where('username', $username);
$query = $this->db->get();
if ($this->db->affected_rows())
{
return $query->row();
}
}
On the other hand, I recommend you to use an existing authentication library.
Ion Auth is pretty good.
Good luck!
