Full Featured Registration and Login Module in CodeIgniter

Registration and Login is one of the primary module in any data management system. In this tutorial, we will explain how to create user Registration authentication and user Login system using the CodeIgniter with activation process. Once active the user can login, a reset option is available to reset the password and etc. Also Using password_hash() and password_verify() algorithm.

Features of Registration and Login Module

Registration form
Login form
Forgot password
Logout feature
password_hash() algorithm
password_verify() algorithm
Change Password feature
Email authentication for registration process
Using SMTP (Simple Mail Transfer Protocol)
Forms validations on login and registration panel
On success the module redirects to the user profile page

Step 1: Create Database

For this tutorial, you need a MySQL database with the following table:

<?php
//Table structure for table import
CREATE TABLE `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT 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',
  `contact_no` VARCHAR(16) NOT NULL COMMENT 'Contact No',
  `password` varchar(255) NOT NULL COMMENT 'Password',
  `address` TEXT NOT NULL COMMENT 'Address',
  `dob` varchar(15) NOT NULL COMMENT 'Date Of Birth',  
  `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',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='datatable demo table' AUTO_INCREMENT=1;
?>

<?php

//Table structure for table import

CREATE TABLE `users` (

`id` int(11) NOT NULL AUTO_INCREMENT 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',

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

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

`address` TEXT NOT NULL COMMENT 'Address',

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

`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',

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='datatable demo table' AUTO_INCREMENT=1;

Step 2: Configure Database access

Update the file application/config/database.php in your CodeIgniter installation with your database info:

<?php
  // configure database
  $db['default'] = array(
    'dsn' => '',
    'hostname' => 'localhost',
    'username' => 'XXXX', // Your username if required.
    'password' => 'XXXX', // Your password if any.
    'database' => 'XXXX_DB', // Your database name.
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
  );
?>

<?php

// configure database

$db['default'] = array(

'dsn' => '',

'hostname' => 'localhost',

'username' => 'XXXX', // Your username if required.

'password' => 'XXXX', // Your password if any.

'database' => 'XXXX_DB', // Your database name.

'dbdriver' => 'mysqli',

'dbprefix' => '',

'pconnect' => FALSE,

'db_debug' => (ENVIRONMENT !== 'production'),

'cache_on' => FALSE,

'cachedir' => '',

'char_set' => 'utf8',

'dbcollat' => 'utf8_general_ci',

'swap_pre' => '',

'encrypt' => FALSE,

'compress' => FALSE,

'stricton' => FALSE,

'failover' => array(),

'save_queries' => TRUE

);

Step 3: Update routes file

Add code the file application/config/routes.php in your CodeIgniter installation with you controller’s name.

<?php 
  // create routes path
  $route['signup'] = 'auth/register';
  $route['signin'] = 'auth/login';
  $route['profile'] = 'auth/index';
  $route['setting'] = 'auth/changepwd';
  $route['profile/edit'] = 'auth/edit';
  $route['forgotpwd'] = 'auth/forgotpassword';
?>

<?php

// create routes path

$route['signup'] = 'auth/register';

$route['signin'] = 'auth/login';

$route['profile'] = 'auth/index';

$route['setting'] = 'auth/changepwd';

$route['profile/edit'] = 'auth/edit';

$route['forgotpwd'] = 'auth/forgotpassword';

Step 4: Update autoload file

In the file application/config/autoload.php you can configure the default libraries you want to load in all your controllers. For our case, we’ll load the database and session libraries, since we want to handle user sessions, and also the URL helper for internal link generation.

<?php 
  // load libraries
  $autoload['libraries'] = array('database', 'session', 'table', 'upload');
  // load helper
  $autoload['helper'] = array('url', 'form', 'html', 'date');
?>

<?php

// load libraries

$autoload['libraries'] = array('database', 'session', 'table', 'upload');

// load helper

$autoload['helper'] = array('url', 'form', 'html', 'date');

Step 5: Create Model

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

<?php
