Get Userdata from database by Login Sessions Codeigniter 3 - codeigniter

Question

i'm trying to make a login system. When user already login it will show user personal data like name, email or something. I'm try to modify the login code but doesn't work. Maybe someone can help.
Here is my code.
Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class User_login extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('Model_user');
$this->load->library('form_validation');
}
public function index()
{
$this->load->view('user/user_login');
}
function aksi_login(){
$username = $this->input->post('username');
$password = $this->input->post('password');
$where = array(
'username' => $username,
'password' => $password,
'status' => 1
);
$cek = $this->Model_user->cek_login('tb_user',$where)->num_rows();
if($cek > 0){
$data_session = array(
'username' => $username,
'status' => "userlogin"
);
$this->session->set_userdata($data_session);
redirect('user/user_dash');
}else{
$this->session->set_flashdata('flash_data', '<div class="alert alert-danger" role="alert" style="font-size:12px">
<center><b>Sorry !!</b> Username / Password is not correct.
</center>
</div>');
redirect('user/user_login');
}
}
function logout(){
$this->session->sess_destroy();
redirect('user/user_login');
}
}?>
Model
function cek_login($table,$where){
return $this->db->get_where($table,$where);
}
I'm can make username session appear,
<?php echo $this->session->userdata('username') ?> it's working.
But try to show name it doesnt appear. Appreciate any kind help. Thank you

Answer 1

You can try something like this.
$query = $this->Model_user->cek_login('tb_user',$where);
if($query->num_rows() > 0){
$user = $query->row();
$data_session = array(
'username' => $username,
'status' => "userlogin",
'name' => $user->name,
);
$this->session->set_userdata($data_session);
redirect('user/user_dash');
} {
$this->session->set_flashdata('flash_data', '<div class="alert alert-danger" role="alert" style="font-size:12px">
<center><b>Sorry !!</b> Username / Password is not correct.
</center>
</div>');
redirect('user/user_login');
}
For this to work, there must be a name column in the table tb_user

You need to store the full name in the session too.
Try editing this
$cek = $this->Model_user->cek_login('tb_user',$where)->num_rows();
if($cek > 0){
$data_session = array(
'username' => $username,
'status' => "userlogin"
);
to this
$cek = $this->Model_user->cek_login('tb_user',$where);
if($cek->num_rows() == 1){
$row=$cek->result_array()[0]; //returns an array of results, pick the first
$data_session = array(
'fullname' => $row['fullname'], //assuming column name is 'fullname'
'username' => $username,
'status' => "userlogin",
);
