Create Registration Form using CodeIgniter and MySQL

In this post, We have to share How to Create a Registration Form in CodeIgniter and Bootstrap Framework along with MySQL Database and using MD5 is a 128-bit encryption algorithm. By using this users can easily register, username, first name, last name, email, password fields. After submitting the form, the data will be stored in a database table.This is a very simple example, you can just copy-paste and change according to your requirement.

Before started to implement the Create Registration using CodeIgniter, look files structure:

create-registration-form-with-codeignite
- application
  - config
    - autoload.php
    - constants.php
    - routes.php
  - models
    - Users_model.php
  - controllers
    - Users.php
  - views
    - users
      - thank-you.php
      - index.php
    - templates
      - header.php
      - footer.php
- system
- index.php
- assets
  - images
  - css

Step 1: Create MySQL Database and Table for User Registration

<?php
  CREATE TABLE `users` (
    `user_id` int(12) NOT NULL,
    `name` varchar(50) DEFAULT NULL,
    `user_name` varchar(50) NOT NULL,
    `email` varchar(255) NOT NULL,
    `password` varchar(255) NOT NULL,
    `status` int(1) NOT NULL
  ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

  ALTER TABLE `users`
    ADD PRIMARY KEY (`user_id`),
    ADD UNIQUE KEY `email` (`email`);

  ALTER TABLE `users`
    MODIFY `user_id` int(12) NOT NULL AUTO_INCREMENT;
  COMMIT;
?>

<?php

CREATE TABLE `users` (

`user_id` int(12) NOT NULL,

`name` varchar(50) DEFAULT NULL,

`user_name` varchar(50) NOT NULL,

`email` varchar(255) NOT NULL,

`password` varchar(255) NOT NULL,

`status` int(1) NOT NULL

) ENGINE=InnoDB DEFAULT CHARSET=latin1;

ALTER TABLE `users`

ADD PRIMARY KEY (`user_id`),

ADD UNIQUE KEY `email` (`email`);

ALTER TABLE `users`

MODIFY `user_id` int(12) NOT NULL AUTO_INCREMENT;

COMMIT;

Step 2: Create a model file User Registration

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

<?php

/**
 * Description of Export Controller
 *
 * @author TechArise Team
 *
 * @email  info@techarise.com
 */
defined('BASEPATH') or exit('No direct script access allowed');

class Users_model extends CI_Model
{
  // declare private variable
  private $_userID;
  private $_name;
  private $_userName;
  private $_email;
  private $_password;
  private $_status;

  public function setUserID($userID)
  {
    $this->_userID = $userID;
  }
  public function setName($name)
  {
    $this->_name = $name;
  }
  public function setUserName($userName)
  {
    $this->_userName = $userName;
  }
  public function setEmail($email)
  {
    $this->_email = $email;
  }
  public function setPassword($password)
  {
    $this->_password = $password;
  }
  public function setStatus($status)
  {
    $this->_status = $status;
  }

  public function createUser()
  {
    $data = array(
      'name' => $this->_name,
      'email' => $this->_email,
      'user_name' => $this->_userName,
      'password' => $this->_password,
      'status' => $this->_status,
    );
    $this->db->insert('users', $data);
    return $this->db->insert_id();
  }
}

?>

<?php

/**

* Description of Export Controller

* @author TechArise Team

* @email info@techarise.com

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

class Users_model extends CI_Model

{

// declare private variable

private $_userID;

private $_name;

private $_userName;

private $_email;

private $_password;

private $_status;

public function setUserID($userID)

{

$this->_userID = $userID;

}

public function setName($name)

{

$this->_name = $name;

}

public function setUserName($userName)

{

$this->_userName = $userName;

}

public function setEmail($email)

{

$this->_email = $email;

}

public function setPassword($password)

{

$this->_password = $password;

}

public function setStatus($status)

{

$this->_status = $status;

}

public function createUser()

{

$data = array(

'name' => $this->_name,

'email' => $this->_email,

'user_name' => $this->_userName,

'password' => $this->_password,

'status' => $this->_status,

);

$this->db->insert('users', $data);

return $this->db->insert_id();

}

Step 3: Create a controller file User Registration

Next create a controller file named “Users.php” inside “application/controllers” folder.

<?php

/**
 * Description of Export Controller
 *
 * @author TechArise Team
 *
 * @email  info@techarise.com
 */
defined('BASEPATH') or exit('No direct script access allowed');

class Users extends CI_Controller
{

  public function __construct()
  {
    parent::__construct();
    $this->load->model('Users_model', 'user');
  }
  // Dashboard
  public function index()
  {
    $data['title'] = 'Dashboard - Tech Arise';
    $data['metaDescription'] = 'Dashboard';
    $data['metaKeywords'] = 'Dashboard';
    $this->load->view('users/thank-you', $data);
  }
  // Register
  public function register()
  {
    $data['title'] = 'Register - Tech Arise';
    $data['metaDescription'] = 'Register';
    $data['metaKeywords'] = 'Register';
    $this->load->view('users/index', $data);
  }
  // Action Register
  public function actionRegister()
  {
    $this->load->library('form_validation');
    // field name, error message, validation rules
    $this->form_validation->set_rules('name', 'Name', 'required');
    $this->form_validation->set_rules('username', 'User Name', 'trim|required|min_length[4]');
    $this->form_validation->set_rules('email', 'Your Email', 'trim|required|valid_email');
    $this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_length[32]');
    $this->form_validation->set_rules('confirm_password', 'Password Confirmation', 'trim|required|matches[password]');

    if ($this->form_validation->run() == FALSE) {
      $this->register();
    } else {
      // post values
      $name = $this->input->post('name');
      $username = $this->input->post('username');
      $email = $this->input->post('email');
      $password = $this->input->post('password');
      // set post values
      $this->user->setName($name);
      $this->user->setUserName($username);
      $this->user->setEmail($email);
      $this->user->setPassword(MD5($password));
      $this->user->setStatus(1);
      // insert values in database
      $this->user->createUser();
      redirect('users/index');
    }
  }
}

?>

<?php

/**

* Description of Export Controller

* @author TechArise Team

* @email info@techarise.com

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

class Users extends CI_Controller

{

public function __construct()

{

parent::__construct();

$this->load->model('Users_model', 'user');

}

// Dashboard

public function index()

{

$data['title'] = 'Dashboard - Tech Arise';

$data['metaDescription'] = 'Dashboard';

$data['metaKeywords'] = 'Dashboard';

$this->load->view('users/thank-you', $data);

}

// Register

public function register()

{

$data['title'] = 'Register - Tech Arise';

$data['metaDescription'] = 'Register';

$data['metaKeywords'] = 'Register';

$this->load->view('users/index', $data);

}

// Action Register

public function actionRegister()

{

$this->load->library('form_validation');

// field name, error message, validation rules

$this->form_validation->set_rules('name', 'Name', 'required');

$this->form_validation->set_rules('username', 'User Name', 'trim|required|min_length[4]');

$this->form_validation->set_rules('email', 'Your Email', 'trim|required|valid_email');

$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_length[32]');

$this->form_validation->set_rules('confirm_password', 'Password Confirmation', 'trim|required|matches[password]');

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

$this->register();

} else {

// post values

$name = $this->input->post('name');

$username = $this->input->post('username');

$email = $this->input->post('email');

$password = $this->input->post('password');

// set post values

$this->user->setName($name);

$this->user->setUserName($username);

$this->user->setEmail($email);

$this->user->setPassword(MD5($password));

$this->user->setStatus(1);

// insert values in database

$this->user->createUser();

redirect('users/index');

}

Step 4: Create a view file for User Registration

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

<?php $this->load->view('templates/header'); ?>
<main role="main" class="container mcontainer">
    <div class="wrapper">
        <form action="<?php echo base_url(); ?>users/actionregister" method="post" id="loginform" name="Login_Form" class="form-signin" method="POST">
            <h4 class="form-signin-heading">Create Registration Form with CodeIgniter</h4>
            <?php if (validation_errors()) { ?>
                <div class="alert alert-danger">
                    <?php echo validation_errors(); ?>
                </div>
            <?php } ?>
            <div class="form-group">
                <label for="name">Name</label>
                <input type="text" class="form-control" id="name" name="name" placeholder="Name*" required />
            </div>

            <div class="form-group">
                <label for="name">User Name</label>
                <input type="text" class="form-control" id="user-name" name="username" placeholder="User Name*" required />
            </div>

            <div class="form-group">
                <label for="name">Email</label>
                <input type="email" class="form-control" id="email" name="email" placeholder="Email*" required />
            </div>

            <div class="form-group">
                <label for="name">Password</label>
                <input type="password" class="form-control" id="password" name="password" placeholder="Password" required />
            </div>

            <div class="form-group">
                <label for="exampleInputPassword1">Confirm Password</label>
                <input type="password" class="form-control" id="password-confirm" name="confirm_password" placeholder="Confirm Password" required />
            </div>
            <button type="submit" class="btn btn-primary" style="float:right">Register</button>
        </form>
    </div>
</main>
<?php $this->load->view('templates/footer'); ?>

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

<form action="<?php echo base_url(); ?>users/actionregister" method="post" id="loginform" name="Login_Form" class="form-signin" method="POST">

<h4 class="form-signin-heading">Create Registration Form with CodeIgniter</h4>

<?php if (validation_errors()) { ?>

<?php echo validation_errors(); ?>

</div>

<?php } ?>

</div>

</div>

<label for="name">Email</label>

</div>

<label for="name">Password</label>

</div>

<label for="exampleInputPassword1">Confirm Password</label>

</div>

<button type="submit" class="btn btn-primary" style="float:right">Register</button>

</form>

</div>

</main>

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

Step 5: Create a Thank you page

Create a view file named “thank-you.php” inside “application/views/users” folder.

  <?php
$this->load->view('templates/header');
?>
<main role="main" class="container mcontainer">
    <div class="wrapper thank-you-page">
        <div class="thank-you-pop">
            <img src="<?php echo HTTP_IMAGES_PATH; ?>tick.png" alt="">
            <h1>Thank You!</h1>
            <p>Your submission is received and we will contact you soon</p>
        </div>
        <hr>
        <div class="row">
            <div class="col-lg-8 offset-2">
                <a href="<?php echo base_url(); ?>register" class="btn btn-sm btn-primary" style="float:right"><i class="fa fa-user"></i> Register</a>
                <a class="btn btn-primary btn-sm" href="<?php echo base_url(); ?>create-registration-form-with-codeigniter-and-bootstrap/"><i class="fa fa-mail-reply"></i> Back To Tutorial</a>
            </div>
        </div>
    </div>
</main>
<?php
$this->load->view('templates/footer');
?>

<?php

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

<h1>Thank You!</h1>

<p>Your submission is received and we will contact you soon</p>

</div>

<hr>

<a href="<?php echo base_url(); ?>register" class="btn btn-sm btn-primary" style="float:right"><i class="fa fa-user"></i> Register</a>

<a class="btn btn-primary btn-sm" href="<?php echo base_url(); ?>create-registration-form-with-codeigniter-and-bootstrap/"><i class="fa fa-mail-reply"></i> Back To Tutorial</a>

</div>

</main>

<?php

$this->load->view('templates/footer');

So open “application/config/routes.php” file and add code like as bellow:

<?php
  // routes
  $route['default_controller'] = 'users/register';
?>

<?php

// routes

$route['default_controller'] = 'users/register';
