Answer 1

You chose the wrong segment number on line $data['records']= $this->profile_model->getprofiledata($this->uri->segment(3));.
Take notice that segment counting starts with zero, so segment no 3 is actually the 4th one in the uri.
If you keep the user id inside your session, you should replace $data['records']= $this->profile_model->getprofiledata($this->uri->segment(3)); with $records = $this->profile_model->getprofiledata($this->session->userdata('profile_id'))‌​‌​‌​;. And you're done.

Answer 2

add a new session when you login process like bellow in your login model :
<?php
public function login_user($user_name = '', $password=''){
$userdetails = array(
'email' => $user_name,
'password' => md5($password),
'status'=>1,
);
$this->db->where($userdetails);
$query = $this->db->get('profile_details');
if($query->num_rows()):
$user = $query->result();
$sess_arry = array(
'profile_id' => $user[0]->profile_id, // add new session profile_id
'first_name' => $user[0]->first_name
);
$this->session->set_userdata('admin_logged_in', $sess_arry); //add admin details to session
return true;
else:
return false;
endif;
}
?>
And some change your index method like bellow :
<?php
public function index()
{
if($this->session->userdata('admin_logged_in')){
$data['admin_details'] = $this->session->userdata('admin_logged_in');
$data['country'] = $this->signup_model->getcountry();
$data['states'] = $this->profile_model->getstates();
$profile_id = $this->session->userdata('profile_id');
$records = $this->profile_model->getprofiledata($profile_id)‌​‌​;
$data['records']= $records;
$data['mainpage']='profile';
$this->load->view('templates/template',$data);
$this->load->view('templates/sidebar',$data);
}
else{
$this->load->view('welcome');
}
}
?>
I have added new 3 line because i thinks you are no getting profile id properly in $this->uri->segment(3)
So,
$profile_id = $this->session->userdata('profile_id');
$records = $this->profile_model->getprofiledata($profile_id)‌​‌​;
$data['records']= $records;
