Question

I want to limit access to certain elements of a user’s profile so that only the user can see them and not other logged in users. So far the is_logged_in function (see below) works fine, now I need to refine it so that it is limited to a specific user that is logged in.

I’m already including a user_id variable in my session data, so that’s available for use.

function is_logged_in()
{
    $is_logged_in = $this->session->userdata('is_logged_in');
    if($is_logged_in)
    {   
        $this->index();
    }
    else
    {
        redirect('fooview');
    }
}

Answer 1

you will need to know the user_id of the profile you are viewing, lets assume in your controller you have it as $user_id.

in your controller you can do $is_owner = $this->session->userdata('user_id') == $user_id ? true : false;

then pass it to your view as e.g. $is_owner.

then in your view simply have

if($is_owner){
  //show stuff
} else {
  //message saying stuff is private!
}
