create user registration form in codeigniter 3
In this article, we are going to create / make a USER Registration form in codeIgniter 3. we will be seeing following things:
- Form validation
- Setting success message using session
- User Email already exists or not in users table.
Before getting started:
- Make your database connection ready:
- Create a table in your database named users as follows:
CREATE TABLE users (
id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
first_name VARCHAR(30) NOT NULL,
last_name VARCHAR(30) NOT NULL,
email VARCHAR(50),
password VARCHAR(50),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
)
So Let's get started:
Step 1: Create a URL named register in your routes.php file path: application/config/routes.php as follows:
$route['register']['GET'] = 'Auth/RegisterController/index';
$route['register']['POST'] = 'Auth/RegisterController/register';
Step 2: Create a register.php file in path: application/views/auth/register.php for form design as follows:
<div class="py-5">
<div class="container">
<div class="row justify-content-center">
<div class="col-md-7">
<?php if($this->session->flashdata('status')) : ?>
<div class="alert alert-success">
<?= $this->session->flashdata('status'); ?>
</div>
<?php endif; ?>
<div class="card shadow">
<div class="card-header">
<h5>Registe</h5>
</div>
<div class="card-body">
<form action="<?php echo base_url('register') ?>" method="POST">
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label for="">First Name</label>
<input type="text" name="first_name" value="<?php echo set_value('first_name'); ?>" class="form-control">
<small><?php echo form_error('first_name'); ?></small>
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label for="">Last Name</label>
<input type="text" name="last_name" value="<?php echo set_value('last_name'); ?>" class="form-control">
<small><?php echo form_error('last_name'); ?></small>
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label for="">Email Address</label>
<input type="email" name="email" value="<?php echo set_value('email'); ?>" class="form-control">
<small><?php echo form_error('email'); ?></small>
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label for="">Password</label>
<input type="password" name="password" class="form-control">
<small><?php echo form_error('password'); ?></small>
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label for="">Confirm Password</label>
<input type="password" name="cpassword" class="form-control">
<small><?php echo form_error('cpassword'); ?></small>
</div>
</div>
<div class="col-md-12">
<button type="submit" class="btn btn-primary px-5">Register Now</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
</div>
Step 3: Create a file named header.php file in path: application/views/template/header.php for extending this into your register.php file.
<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<title>Funda of Web IT</title>
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css">
</head>
<body>
Step 4: Create a file named footer.php file in path: application/views/template/footer.php for extending this into your register.php file.
<script src="https://code.jquery.com/jquery-3.5.1.js"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.1/dist/umd/popper.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/js/bootstrap.min.js"></script>
</body>
</html>
Step 5: Go to your autoload.php file where path: application/config/autoload.php and add or replace with the below code:
$autoload['libraries'] = array('database','session');
Step 6: Let's Create a controller named RegisterController.php in the path: application/controllers/Auth/RegisterController.php and follow as below:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class RegisterController extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper('form');
$this->load->library('form_validation');
$this->load->model('UserModel');
}
public function index()
{
$this->load->view('template/header.php');
$this->load->view('auth/register.php');
$this->load->view('template/footer.php');
}
public function register()
{
$this->form_validation->set_rules('first_name', 'First Name', 'trim|required|alpha');
$this->form_validation->set_rules('last_name', 'Last Name', 'trim|required|alpha');
$this->form_validation->set_rules('email', 'Email ID', 'trim|required|valid_email|is_unique[users.email]');
$this->form_validation->set_rules('password', 'Password', 'trim|required');
$this->form_validation->set_rules('cpassword', 'Confirm Password', 'trim|required|matches[password]');
if($this->form_validation->run() == FALSE)
{
// failed
$this->index();
}
else
{
$data = array(
'first_name' => $this->input->post('first_name'),
'last_name' => $this->input->post('last_name'),
'email' => $this->input->post('email'),
'password' => $this->input->post('password')
);
$register_user = new UserModel;
$checking = $register_user->registerUser($data);
if($checking)
{
$this->session->set_flashdata('status','Registered Successfully.! Go to Login');
redirect(base_url('register'));
}
else
{
$this->session->set_flashdata('status','Something Went Wrong.!');
redirect(base_url('register'));
}
}
}
}
?>
Step 7: Create a model named UserModel.php file in path: application/models/UserModel.php as follows:
<?php
class UserModel extends CI_Model
{
public function registerUser($data)
{
return $this->db->insert('users', $data);
}
}
?>
