<?php
defined('BASEPATH') OR exit('No direct script access allowed');
error_reporting(0);
class Welcome extends CI_Controller {

public function __construct()
{
parent::__construct();
$this->load->library('microsoft');

redirect('welcome/profile', $data);

}else{

}

}








public function profile()
{
if($this->session->userdata('user_id') != ''){
$this->data['userprofile']= $this->welcome->fetch_user();
$this->load->view('profile', $this->data, FALSE);
}else{
redirect('welcome', $data);
}
}




public function logout()
{
$this->session->sess_destroy();
redirect(base_url(), redirect);
}
}

  

STEP 9 : MODEL
Welcome_model.php

<?php
class Welcome_model extends CI_Model
{
public function __construct()
{
parent::__construct();
}


public function insert_user($data){
$this->db->insert('users', $data); 
return TRUE;
}

public function fetch_user(){
$query=$this->db->query("SELECT *
 FROM users
 WHERE id = '".$this->session->userdata('user_id')."' ");
//return $query->result();
return $query->row(0);
}



}

STEP 10 : VIEWS
1. profile.php
2. login.php / welcome_message.php

PROFILE.PHP has to view the user data in that page.

LOGIN.PHP / WELCOME_MESSAGE.PHP file is to give login url link.

<a href="<?php echo $this->microsoft->loginURL(); ?>">
<span class="fa fa-windows"></span> Sign in with Microsoft
</a>
