I have problem with my session login in codeigniter 3. I can't get data from database to insert session. Whats wrong with my code?
My Controller

parent::__construct();
$this->load->model('m_login');
}
function index(){
$this->load->view('v_login');
}
function aksi_login(){
$username = $this->input->post('username');
$password = $this->input->post('password');
$where = array(
'username' => $username,
'password' => md5($password)
);
$cek = $this->m_login->cek_login("admin",$where)->num_rows();
if($cek > 0){
$data_session = array(
'username' => $cek['username'],
'nama' => $cek['nama']
'status' => "login"
);
$this->session->set_userdata($data_session);
redirect(base_url("admin"));
}else{
echo "Username dan password salah !";
}
}
}
My Model
<?php
class M_login extends CI_Model{
function cek_login($table,$where){
return $this->db->get_where($table,$where);
}
}

Answer 1

1.m_login->cek_login
this functions returns a SQL QUERY OBJECT
2.the SQL QUERY OBJECT ->num_rows() function returns a INT ($cek)
3.so $cek is a INT . so u cant use like an array ($cek['username'])
so Please try this code
function aksi_login(){
$username = $this->input->post('username');
$password = $this->input->post('password');
$where = array(
'username' => $username,
'password' => md5($password)
);
$cek = $this->m_login->cek_login("admin",$where);//$cek is a Query Object
$rows = $cek->num_rows();//$rows is a INT
if($rows > 0){
$cek = $cek->row_array();//now u get an Array
$data_session = array(
'username' => $cek['username'],
'nama' => $cek['nama']
'status' => "login"
);
$this->session->set_userdata($data_session);
redirect(base_url("admin"));
}else{
echo "Username dan password salah !";
}
}

Answer 2

Try This
if($cek > 0){
$cek = $cek->row_array();
$data_session = array(
'username' => $cek['username'],
'nama' => $cek['nama']
'status' => "login"
);
$this->session->set_userdata($data_session);
redirect(base_url("admin"));
}else{
echo "Username dan password salah !";
}

Try like this...
In codeigniter row_array() takes the first matched row in array format.So your function aksi_login() must be like this...
function aksi_login(){
$username = $this->input->post('username');
$password = $this->input->post('password');
$where = array(
'username' => $username,
'password' => md5($password)
);
$result = $this->m_login->cek_login("admin",$where);
$cek = $this->m_login->cek_login("admin",$where)->num_rows();
if($cek > 0){
$cek = $result->row_array();//no your records are in array format having matched row
$data_session = array(
'username' => $cek['username'],
'nama' => $cek['nama']
'status' => "login"
);
$this->session->set_userdata($data_session);
redirect(base_url("admin"));
}else{
echo "Username dan password salah !";
}
}
