Codeigniter remove follow button after following user

#1
Hi I am able to display users friends on a page but when I into the friends profile I still see the follow button, is there anyway I can remove the button after following? I am using codeigniter. see code.
Model:

Code:
public function get_friends($user_id = NULL){
   if ($user_id = $this->session->userdata('user_id')){
   $this->db->select('*');
   $this->db->from('users');
   $this->db->join('friends', 'friends.user_id = users.user_id');
   $this->db->where('friends.user_id2', $user_id);
   $query = $this->db->get();
   return $query->result_array($user_id);
       }
}


Controller

You're passing $data['friends'] to your view. But in the view, you immediately overwrite $friends with some session variable 'user_id2'. So, the friends from your model aren't recognized.

You are right there, but you see in the view when I use $friends['username']; it throws an error saying Message: Undefined variable: friends, even when friends is defined in the controller.

You are not passing the $members[] array in the controller.

Something seems to be missing eitehr in your controller or view.
On the package it said needs Windows 7 or better. So I installed Linux.
