Login with Remember Me using CodeIgniter| Tech Arise

In this tutorial, we have to share how to log in with Remember Me using CodeIgniter and MySQL. Remember me function is used to save the login details in the login form entered by the user. This is a very user-friendly feature that helps the user in reducing user attempts and stop to type login details every time again and again. This is a very simple example, you can just copy-paste, and change according to your requirement.

Before started to implement the Login with Remember Me, look files structure:

codeigniter-login-with-remember-me
- application
  - config
    - constants.php
    - routes.php
  - controllers
    - Auth.php
  - models
    - Auth_model.php
  - views
    - auth
      - login.php
      - index.php
    - templates

A simple step-by-step guide to help you Login with Remember Me Codeigniter.

Step 1: Create MySQL Database and Table

<?php
    CREATE TABLE `users` (
        `id` int(11) NOT NULL COMMENT 'Primary Key',
        `first_name` varchar(100) NOT NULL COMMENT 'First Name',
        `last_name` varchar(100) NOT NULL COMMENT 'Last Name',
        `user_name` varchar(100) NOT NULL COMMENT 'Last Name',
        `email` varchar(255) NOT NULL COMMENT 'Email Address',
        `password` varchar(255) NOT NULL COMMENT 'Password',
        `address` text NOT NULL,
        `dob` varchar(15) NOT NULL COMMENT 'Date Of Birth',
        `contact_no` varchar(16) NOT NULL COMMENT 'Contact No',
        `url` int(255) DEFAULT NULL,
        `verification_code` varchar(255) NOT NULL COMMENT 'verification Code',
        `created_date` varchar(12) NOT NULL COMMENT 'created timestamp',
        `modified_date` varchar(12) NOT NULL COMMENT 'modified timestamp',
        `status` char(1) NOT NULL COMMENT '0=pending, 1=active, 2=delete'
    ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='datatable demo table';

    INSERT INTO `users` (`id`, `first_name`, `last_name`, `user_name`, `email`, `password`, `address`, `dob`, `contact_no`, `url`, `verification_code`, `created_date`, `modified_date`, `status`) VALUES
    (1, 'Demo', 'Demo', 'demo', 'demo@web.com', '$2y$10$jnsHMT.l7WhIYpMxyuSt0ewQkoV/P4/79MucCyd8zxZADoIw34/nW', 'Street 3111  Massachusetts Avenue, Washington, USA', '01-02-1990', '9000000001', NULL, '1', '1559545393', '1559545393', '1');

    ALTER TABLE `users`
        ADD PRIMARY KEY (`id`);

    ALTER TABLE `users`
        MODIFY `id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key', AUTO_INCREMENT=2;
?>

<?php

CREATE TABLE `users` (

`id` int(11) NOT NULL COMMENT 'Primary Key',

`first_name` varchar(100) NOT NULL COMMENT 'First Name',

`last_name` varchar(100) NOT NULL COMMENT 'Last Name',

`user_name` varchar(100) NOT NULL COMMENT 'Last Name',

`email` varchar(255) NOT NULL COMMENT 'Email Address',

`password` varchar(255) NOT NULL COMMENT 'Password',

`address` text NOT NULL,

`dob` varchar(15) NOT NULL COMMENT 'Date Of Birth',

`contact_no` varchar(16) NOT NULL COMMENT 'Contact No',

`url` int(255) DEFAULT NULL,

`verification_code` varchar(255) NOT NULL COMMENT 'verification Code',

`created_date` varchar(12) NOT NULL COMMENT 'created timestamp',

`modified_date` varchar(12) NOT NULL COMMENT 'modified timestamp',

`status` char(1) NOT NULL COMMENT '0=pending, 1=active, 2=delete'

) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='datatable demo table';

INSERT INTO `users` (`id`, `first_name`, `last_name`, `user_name`, `email`, `password`, `address`, `dob`, `contact_no`, `url`, `verification_code`, `created_date`, `modified_date`, `status`) VALUES

(1, 'Demo', 'Demo', 'demo', 'demo@web.com', '$2y$10$jnsHMT.l7WhIYpMxyuSt0ewQkoV/P4/79MucCyd8zxZADoIw34/nW', 'Street 3111 Massachusetts Avenue, Washington, USA', '01-02-1990', '9000000001', NULL, '1', '1559545393', '1559545393', '1');

ALTER TABLE `users`

ADD PRIMARY KEY (`id`);

ALTER TABLE `users`

MODIFY `id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key', AUTO_INCREMENT=2;

Step 2: Create a model file

Create a model file named Auth_model.php inside “application/models” folder.

<?php

if (!defined('BASEPATH'))
    exit('No direct script access allowed');

class Auth_model extends CI_Model {
    // Declaration of a variables   
    private $_userName;
    private $_password;   

    public function setUserName($userName) {
        $this->_userName = $userName;
    }
    public function setPassword($password) {
        $this->_password = $password;
    }
       
    // login method and password verify
    function login() {
        $this->db->select('id as user_id, user_name, email, password');
        $this->db->from('users');
        $this->db->where('email', $this->_userName);
        $this->db->where('verification_code', 1);
        $this->db->where('status', 1);
        //{OR}
        $this->db->or_where('user_name', $this->_userName);
        $this->db->where('verification_code', 1);
        $this->db->where('status', 1);
        $this->db->limit(1);
        $query = $this->db->get();
        if ($query->num_rows() == 1) {
            $result = $query->result();
            foreach ($result as $row) {
                if ($this->verifyHash($this->_password, $row->password) == TRUE) {
                    return $result;
                } else {
                    return FALSE;
                }
            }
        } else {
            return FALSE;
        }
    }
    
    // password verify
    public function verifyHash($password, $vpassword) {
        if (password_verify($password, $vpassword)) {
            return TRUE;
        } else {
            return FALSE;
        }
    }

}
?>
?>

<?php

/* * ***

if (!defined('BASEPATH'))

exit('No direct script access allowed');

class Auth_model extends CI_Model {

// Declaration of a variables

private $_userName;

private $_password;

public function setUserName($userName) {

$this->_userName = $userName;

}

public function setPassword($password) {

$this->_password = $password;

}

// login method and password verify

function login() {

$this->db->select('id as user_id, user_name, email, password');

$this->db->from('users');

$this->db->where('email', $this->_userName);

$this->db->where('verification_code', 1);

$this->db->where('status', 1);

//{OR}

$this->db->or_where('user_name', $this->_userName);

$this->db->where('verification_code', 1);

$this->db->where('status', 1);

$this->db->limit(1);

$query = $this->db->get();

if ($query->num_rows() == 1) {

$result = $query->result();

foreach ($result as $row) {

if ($this->verifyHash($this->_password, $row->password) == TRUE) {

return FALSE;

}

// password verify

public function verifyHash($password, $vpassword) {

if (password_verify($password, $vpassword)) {

return TRUE;

} else {

return FALSE;

}

Step 3: Create a controller file

Create a controller file named Auth.php inside “application/controllers” folder.

<?php

/* * ***

 *
 * Description of Auth Controller
 *
 * @author TechArise Team

if (!defined('BASEPATH'))
    exit('No direct script access allowed');

    public function __construct() {
        parent::__construct();

        if ($this->form_validation->run() == FALSE) {

Step 4: Create a view

Create a view file named login.php inside “application/views/auth” folder.

  <?php $this->load->view('templates/header');?>

Step 5: Create a view

Create a view file named index.php inside “application/views/auth” folder.

 <?php $this->load->view('templates/header');?>

.button {
  border: none;
  outline: 0;
  display: inline-block;
  padding: 8px;
  color: white;
  background-color: #3498DB;
  text-align: center;
