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'); ?>
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.
