Codeigniter access session in view

Question

function login(){
    $data = array('username' => $_POST['username'], 'password' => $_POST['password']);
    $this->form_validation->set_rules('username', 'Username', 'required|callback_username_check');
    $this->form_validation->set_rules('password', 'Password', 'required');

    if($this->form_validation->run() == FALSE){
        $this->load->view('Login');
    } else {
        $result = $this->LoginModel->account_check($data);
        if($result){
            if($result['status'] = 'admin'){
                $isLoggedin = array('user_type' => 'administrator' ,'admin_name' => $result['username'] , 'is_loggedin' => TRUE);
                $this->session->set_userdata($isLoggedin);
                $this->load->view('admin/homepage'); 
            } else if($result['status'] = 'user'){
                $isLoggedin = array( 'user_name' => $row['username'] , 'user_type' => 'user' ,  'is_loggedin' => TRUE);
                $this->session->set_user($isLoggedin); 
                $this->load->view('user/homepage'); 
            } 
        }
    }
}

function username_check($username){
    $result = $this->LoginModel->username_check($username);
    if($result != TRUE){
        $this->form_validation->set_message('username_check' , 'Username does not exist');
        return FALSE; 
    } else return TRUE;
}

MODEL:

function username_check($username){
    $query = $this->db->get_where( 'admin' , array('username' => $username))->result_array();
    if(!empty($query)){
        return TRUE;
    }else{
        $query = $this->db->get_where( 'user_mst', array('username' => $username))->result_array();
        if(!empty($query)){
            return TRUE;
        }else return FALSE;
    }
}

function account_check($data){
    $query = $this->db->get_where( 'admin' , array( 'username' => $data['username'] , 'password' => $data['password'] ))->result_array();
    if(!empty($query)){
        foreach($query as $row){
            $result['status'] = 'admin';
            $result['username'] = $row['username'];
            $result['password'] = $row['password'];
            return $result; 
        }
    } else{
        $query = $this->db->get_where( 'user_mst' , array( 'username' => $data['username'] , 'password' => $data['password'] ))->result_array();
        if(!empty($query)){
            foreach($query as $row){
                $result['status'] = 'user';
                $result['username'] = $row['username'];
                $result['password'] = $row['password'];
                return $result; 
            }
        }
    }
}

How do i access the user data, im going to use this to run an if per view if an account is logged in and if it is an admin acc.

I would like to read some opinion regarding how im using the session if i am 100% correct.

Also, i have a question,

This code <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); ?> <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); ?>

blocks direct access to the view, prevents view access but not specifically checks if a user is logged in.

How can i utilize this with the session. If its redundant please tell me,

Answer 1

Codeigniter passes data to the view with a second parameter:

$this->load->view('user/homepage');

doesn't pass any data.

$this->load->view('user/homepage', $data);

Would pass in a $data variable that you could use. ( https://ellislab.com/codeigniter/user-guide/general/views.html )

Another point - I'd consider using the redirect() function after a successful login rather than loading the view you want in the login method. Use the URL Helper to do this ( https://ellislab.com/codeigniter/user-guide/helpers/url_helper.html ).

Hope that helps.
