CodeIgniter - Update Database Record - php

Question

I've done the coding of Update Database record in Codeigniter. Everything works fine but When I click the Save button database records won't update. Each time it's showing the old database records. I want to update the database records but what's wrong with this. I don't understand the missing thing. Help Needed.
My Controller:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Employee extends CI_Controller {
function __construct()
{
parent::__construct();
if($this->session->email == "")
{
redirect('login');
}
$this->load->model('EmployeeModel','EmployeeModel');
}
public function ViewEmployee()
{
$data['getEmployee'] = $this->EmployeeModel->getEmployee();
$this->load->view('view_employee',$data);
}
public function update($empID) {
$data['user'] = $this->EmployeeModel->get_by($empID);
$data['subview'] = 'Employee/edit_employee';
$this->load->view('edit_employee', $data);
}
public function edit() {
$empID = $this->input->post('empID');
//Check whether user upload picture
if(!empty($_FILES['picture']['name'])){
$config['upload_path'] = 'uploads/';
$config['allowed_types'] = 'jpg|jpeg|png|gif';
$config['file_name'] = $_FILES['picture']['name'];
//Load upload library and initialize configuration
$this->load->library('upload',$config);
$this->upload->initialize($config);
if($this->upload->do_upload('picture')){
$uploadData = $this->upload->data();
$picture = $uploadData['file_name'];
}else{
$picture = '';
}
}else{
$picture = '';
}
$data = array(
'empFirstName' => $this->input->post('firstname'),
'empLastName' => $this->input->post('lastname'),
'empNO' => $this->input->post('employee_id'),
'designation' => $this->input->post('designation'),
);
$this->db->where('empID', $empID);
$this->db->update('tbl_employee', $data);
redirect('view_employee');
$this->update($empID);
}
}
My Model:
<?php
class EmployeeModel extends CI_Model
{
function __construct() {
parent::__construct();
}
public function EmployeeRegister($data)
{
$this->db->insert('tbl_employee',$data);
return true;
}
public function getEmployee()
{
$this->db->where('status',0);
$query = $this->db->get('tbl_employee');
return $query->result();
}
public function get_by($empID) {
$this->db->where('empID', $empID);
$user = $this->db->get('tbl_employee')->row();
return $user;
}
}

Use this one to debug your application.
echo $this->db->last_query();
