How to get session array data CodeIgniter - php

Question

I'm not quite sure why the username didn't appear on view page if i change the session data into array (i'm new in CodeIgniter). I have auth controller to make login process:
function index() {
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'username', 'required|trim|xss_clean');
$this->form_validation->set_rules('password', 'password', 'required|trim|xss_clean');
if ($this->form_validation->run() == FALSE) {
$this->load->view('Login');
# code...
}
else {
$username = $this->input->post('username');
$password = $this->input->post('password');
$check = $this->M_login->check($username, $password);
// session data
if ($check->num_rows() == TRUE) {
foreach ($check->result() as $value) {
$sess_data['id'] = $value->id;
$sess_data['name'] = $value->name;
$sess_data['username'] = $value->username;
$sess_data['password'] = $value->password;
$sess_data['description'] = $value->description;
$this->session->set_userdata($sess_data);
}
redirect('Dashboard');
}
else {
$this->session->set_flashdata('result_login', '<br>Invalid username or password, try again.');
redirect('Login');
}
And here is my dashboard controller:
public function __construct() {
parent::__construct();
if(!$this->session->userdata('id')){
redirect('login');
}
}
public function index() {
// Dashboard view
$username = $this->session->userdata('username');
$data['username']=$username;
$this->load->view('Dashboard', $data);
}
function logout() {
$this->session->sess_destroy('id');
redirect('login');
}
With above code, i can get the username on my dashboard view by echo $username. But when i change the session data like this:
if ($check->num_rows() == TRUE) {
foreach ($check->result() as $value) {
// session data
$sess_data = array(
'id' => $value->id,
'username' => $value->username,
'password' => $value->password,
'name' => $value->name,
'description' => $value->description
);
$this->session->set_userdata('log',$sess_data);
}
}
And Dashboard controller changed like this:
if(!$this->session->userdata('id')) {
$getdata= $this->session->userdata('log');
$data['username'] = $getdata['username'];
}
$this->load->view('Dashboard', $data);
Then the username disappeared from view page. How can i store username in session array and call it in view page. Please share your better suggestions or your experience guys.
Thanks.

Answer 1

Adding data in session :-
$newdata = array(
'username' => 'johndoe',
'email' => 'johndoe#some-site.com',
'logged_in' => TRUE
);
$this->session->set_userdata($newdata);
Retrieving Data from session :-
$this->session->all_userdata()
Retrieving single data :-
$session_id = $this->session->userdata('username');

Youcan refer this code
public function loginaction()
{
$this->load->library('session');
$a = $this->input->post('email');
$b = trim($this->input->post('password'));
$b1 = md5($b);
$c = 1;
$data = $this->userdata->userlogin($a,$b1,$c);
if($data)
{
echo true;
foreach ($data as $login)
{
$uid=$this->session->set_userdata('logId',$login->usr_id);
}
}
else
{
echo "Invalid username or password..!!!!";
$a=$this->input->post('email');
}
}

You can do it like
$username = $this->input->post('username');
$password = $this->input->post('password');
$check = $this->M_login->check($username, $password);
if ($check->num_rows() > 0)
{
$value = $check->row();
$sess_data['id'] = $value->id;
$sess_data['name'] = $value->name;
$sess_data['username'] = $value->username;
$sess_data['password'] = $value->password;
$sess_data['description'] = $value->description;
$this->session->set_userdata($sess_data);
redirect('Dashboard');
}
else
{
$this->session->set_flashdata('result_login', '<br>Invalid username or password, try again.');
redirect('Login');
}
And in your view
$username = $this->session->userdata('username');
