---- Controller ----
<?php
defined('BASEPATH') or exit('No direct script access allowed');
class editprofile extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('user');
}
public function index()
{
$this->form_validation->set_rules('email', 'email', 'required|valid_email');
$this->form_validation->set_rules('namalengkap', 'namalengkap', 'required');
$this->form_validation->set_rules('password', 'PASSWORD', 'required');
if ($this->form_validation->run() == false) {
$this->load->view('v_profile');
} else {
$row = $this->session->userdata('id');
$data = array(
'name' => $this->input->post('name'),
'email' => $this->input->post('email'),
'password' => $this->input->post('password'),
'phone' => $this->input->post('phone'),
'address' => $this->input->post('address'),
'kecamatan' => $this->input->post('kecamatan'),
'kelurahan' => $this->input->post('kelurahan'),
'rt' => $this->input->post('rt'),
'rw' => $this->input->post('rw'),
'zip code' => $this->input->post('zip code'),
'city' => $this->input->post('city'),
'province' => $this->input->post('province'),
);
$result = $this->user->update($data, $row);
if ($result > 0) {
$this->updateProfil();
$this->session->set_flashdata('msg', show_succ_msg('Data Profile Berhasil diubah, silakan lakukan login ulang!'));
redirect('c_login/profile');
} else {
$this->session->set_flashdata('msg', show_err_msg('Data Profile Gagal diubah'));
redirect('c_login/profile');
}
}
}
}
----- model -----
<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
class User extends CI_Model
{
private $uid = 'id';
private $tabel = 'users';
public function __construct()
{
parent::__construct();
}
public function login($email, $password)
{
$this->db->where('email', $email);
$this->db->where('password', $password);
return $this->db->get($this->tabel);
}
function update($data, $id)
{
$this->db->where($this->uid, $id);
$this->db->update($this->tabel, $data);
}
public function get_by_cookie($kue)
{
$this->db->where('cookie', $kue);
return $this->db->get($this->tabel);
}
}
----- Core / MY_Controller -----
<?php
defined('BASEPATH') or exit('No direct script access allowed');
class MY_Controller extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('user');
}
public function updateProfil()
{
if ($this->userdata != '') {
$data = $this->user->select($this->userdata->email);
$this->session->set_userdata('userdata', $data);
$this->userdata = $this->session->userdata('userdata');
}
}
}

Answer 1

In your update function you have not set any values. As set method required array values you should give if. Good practice is using set before update and finally update of table. Follow the following codes for updating your users table.
function update($data, $id)
{
$this->db->set($data);
$this->db->where($this->uid, $id);
$this->db->update($this->tabel);
}
use this code. I hope it will work well.

Answer 2

in your controller
$result = $this->user->update($data, $row);
variable data is array
so in your model:
function update($data=array(), $id){
$this->db->where($this->uid, $id);
$this->db->update($this->tabel, $data);
}
