Codeigniter 4 Login and Registration Example

April 12, 2020 XpertPhp

In this article, we will explain to you how to create a User Login logout and register example in Codeigniter 4(Codeigniter 4 Login and Registration Example). Sometimes when creating an admin panel at that time we need to Registration, Login, and log out to Codeigniter 4.

Overview

Step 1: Install Codeigniter 4

Step 2: Setting Database Configuration

Step 3: Create Table using migration

Step 4: Create Controllers and Model

Step 5: Create Custom Validation rules

Step 6: Creating a Filter

Step 7: Define The Route

Step 8: Create View Files

Step 9: Run Our Application

Install Codeigniter 4

If you want to download or install CodeIgniter 4 then you can below Url.
How To Install Codeigniter 4 Using Manual, Composer, Git

Setting Database Configuration

After complete installation of CodeIgniter 4. we have to database configuration. now we will open the .env file and change the database name, username, password in the .env file. See below changes in a .env file.

database.default.hostname = localhost
database.default.database = ci4_login
database.default.username = root
database.default.password =
database.default.DBDriver = MySQLi

database.default.hostname = localhost

database.default.database = ci4_login

database.default.username = root

database.default.password =

database.default.DBDriver = MySQLi

Create Table using migration

Now, We need to migrate the users table. we can easily migrate the user table using the below command.

php spark migrate

1	php spark migrate

Create Controllers and Model

we create the controllers and model. so you can see the below example.

app/Controllers/Login.php

<?php namespace App\Controllers;

use App\Models\UserModel;


class Login extends BaseController
{
	public function index()
	{
		$data = [];
		helper(['form']);


		if ($this->request->getMethod() == 'post') {
			//let's do the validation here
			$rules = [
				'email' => 'required|min_length[6]|max_length[50]|valid_email',
				'password' => 'required|min_length[8]|max_length[255]|validateUser[email,password]',
			];

			$errors = [
				'password' => [
					'validateUser' => 'Email or Password don\'t match'
				]
			];

			if (! $this->validate($rules, $errors)) {
				$data['validation'] = $this->validator;
			}else{
				$model = new UserModel();

				$user = $model->where('email', $this->request->getVar('email'))
											->first();

				$this->setUserSession($user);
				//$session->setFlashdata('success', 'Successful Registration');
				return redirect()->to('dashboard');

			}
		}

		return view('login',$data);
		
	}

	private function setUserSession($user){
		$data = [
			'id' => $user['id'],
			'firstname' => $user['firstname'],
			'lastname' => $user['lastname'],
			'email' => $user['email'],
			'isLoggedIn' => true,
		];

		session()->set($data);
		return true;
	}

	public function register(){
		$data = [];
		helper(['form']);

		if ($this->request->getMethod() == 'post') {
			//let's do the validation here
			$rules = [
				'firstname' => 'required|min_length[3]|max_length[20]',
				'lastname' => 'required|min_length[3]|max_length[20]',
				'email' => 'required|min_length[6]|max_length[50]|valid_email|is_unique[users.email]',
				'password' => 'required|min_length[8]|max_length[255]',
				'password_confirm' => 'matches[password]',
			];

			if (! $this->validate($rules)) {
				$data['validation'] = $this->validator;
			}else{
				$model = new UserModel();

				$newData = [
					'firstname' => $this->request->getVar('firstname'),
					'lastname' => $this->request->getVar('lastname'),
					'email' => $this->request->getVar('email'),
					'password' => $this->request->getVar('password'),
				];
				$model->save($newData);
				$session = session();
				$session->setFlashdata('success', 'Successful Registration');
				return redirect()->to('/');

			}
		}
		return view('register',$data);
	}

	public function logout(){
		session()->destroy();
		return redirect()->to('/');
	}

<?php namespace App\Controllers;

use App\Models\UserModel;

class Login extends BaseController

{

public function index()

{

$data = [];

helper(['form']);

if ($this->request->getMethod() == 'post') {

//let's do the validation here

$rules = [

'email' => 'required|min_length[6]|max_length[50]|valid_email',

'password' => 'required|min_length[8]|max_length[255]|validateUser[email,password]',

];

$errors = [

'password' => [

'validateUser' => 'Email or Password don\'t match'

]

];

if (! $this->validate($rules, $errors)) {

$data['validation'] = $this->validator;

}else{

$model = new UserModel();

$user = $model->where('email', $this->request->getVar('email'))

->first();

$this->setUserSession($user);

//$session->setFlashdata('success', 'Successful Registration');

return redirect()->to('dashboard');

}

return view('login',$data);

}

private function setUserSession($user){

$data = [

'id' => $user['id'],

'firstname' => $user['firstname'],

'lastname' => $user['lastname'],

'email' => $user['email'],

'isLoggedIn' => true,

];

session()->set($data);

return true;

}

public function register(){

$data = [];

helper(['form']);

if ($this->request->getMethod() == 'post') {

//let's do the validation here

$rules = [

'firstname' => 'required|min_length[3]|max_length[20]',

'lastname' => 'required|min_length[3]|max_length[20]',

'email' => 'required|min_length[6]|max_length[50]|valid_email|is_unique[users.email]',

'password' => 'required|min_length[8]|max_length[255]',

'password_confirm' => 'matches[password]',

];

if (! $this->validate($rules)) {

$data['validation'] = $this->validator;

}else{

$model = new UserModel();

$newData = [

'firstname' => $this->request->getVar('firstname'),

'lastname' => $this->request->getVar('lastname'),

'email' => $this->request->getVar('email'),

'password' => $this->request->getVar('password'),

];

$model->save($newData);

$session = session();

$session->setFlashdata('success', 'Successful Registration');

return redirect()->to('/');

}

return view('register',$data);

}

public function logout(){

session()->destroy();

return redirect()->to('/');

}

//--------------------------------------------------------------------

}

And second, we need to update the LoginController.php file. so you can follow the below code.

app/Controllers/Dashboard.php

<?php namespace App\Controllers;

class Dashboard extends BaseController
{
	public function index()
	{
		$data = [];

		return view('dashboard', $data);
	}
}

<?php namespace App\Controllers;

class Dashboard extends BaseController

{

public function index()

{

$data = [];

return view('dashboard', $data);

}

app/Models/UserModel.php

<?php namespace App\Models;

use CodeIgniter\Model;

class UserModel extends Model{
  protected $table = 'users';
  protected $allowedFields = ['firstname', 'lastname', 'email', 'password', 'updated_at'];
  protected $beforeInsert = ['beforeInsert'];
  protected $beforeUpdate = ['beforeUpdate'];




  protected function beforeInsert(array $data){
    $data = $this->passwordHash($data);
    $data['data']['created_at'] = date('Y-m-d H:i:s');

    return $data;
  }

  protected function beforeUpdate(array $data){
    $data = $this->passwordHash($data);
    $data['data']['updated_at'] = date('Y-m-d H:i:s');
    return $data;
  }

  protected function passwordHash(array $data){
    if(isset($data['data']['password']))
      $data['data']['password'] = password_hash($data['data']['password'], PASSWORD_DEFAULT);

    return $data;
  }


}
?>

<?php namespace App\Models;

use CodeIgniter\Model;

class UserModel extends Model{

protected $table = 'users';

protected $allowedFields = ['firstname', 'lastname', 'email', 'password', 'updated_at'];

protected $beforeInsert = ['beforeInsert'];

protected $beforeUpdate = ['beforeUpdate'];

protected function beforeInsert(array $data){

$data = $this->passwordHash($data);

$data['data']['created_at'] = date('Y-m-d H:i:s');

return $data;

}

protected function beforeUpdate(array $data){

$data = $this->passwordHash($data);

$data['data']['updated_at'] = date('Y-m-d H:i:s');

return $data;

}

protected function passwordHash(array $data){

if(isset($data['data']['password']))

$data['data']['password'] = password_hash($data['data']['password'], PASSWORD_DEFAULT);

return $data;

}

Create Custom Validation rules

Here, we create the custom validation rules to check the user is valid or not. so you can follow the below example.
app/Validation/UserRules.php

<?php
namespace App\Validation;
use App\Models\UserModel;

class UserRules
{

  public function validateUser(string $str, string $fields, array $data){
    $model = new UserModel();
    $user = $model->where('email', $data['email'])
                  ->first();

    if(!$user)
      return false;

    return password_verify($data['password'], $user['password']);
  }
}
?>

<?php

namespace App\Validation;

use App\Models\UserModel;

class UserRules

{

public function validateUser(string $str, string $fields, array $data){

$model = new UserModel();

$user = $model->where('email', $data['email'])

->first();

if(!$user)

return false;

return password_verify($data['password'], $user['password']);

}

app/Config/Validation.php
now, we have to add that file. The edit app/Config/Validation.php and add the new file to the $rule Set array.

public $ruleSets = [
		....
		\App\Validation\UserRules::class,
	];

public $ruleSets = [

....

\App\Validation\UserRules::class,

];

Creating a Filter

The filter handles the request before or after the controllers execute. so we are using it to check user authentication.
app/Filters/Auth.php

<?php namespace App\Filters;

use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use CodeIgniter\Filters\FilterInterface;

class Auth implements FilterInterface
{
    public function before(RequestInterface $request)
    {
        // Do something here
        if(! session()->get('isLoggedIn')){
          return redirect()->to('/');
        }
    }

    //--------------------------------------------------------------------

    public function after(RequestInterface $request, ResponseInterface $response)
    {
        // Do something here
    }
}
?>

<?php namespace App\Filters;

use CodeIgniter\HTTP\RequestInterface;

use CodeIgniter\HTTP\ResponseInterface;

use CodeIgniter\Filters\FilterInterface;

class Auth implements FilterInterface

{

public function before(RequestInterface $request)

{

// Do something here

if(! session()->get('isLoggedIn')){

return redirect()->to('/');

}

//--------------------------------------------------------------------

public function after(RequestInterface $request, ResponseInterface $response)

{

// Do something here

}

app/Filters/Noauth.php

<?php namespace App\Filters;

use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use CodeIgniter\Filters\FilterInterface;

class Noauth implements FilterInterface
{
    public function before(RequestInterface $request)
    {
        // Do something here
        if(session()->get('isLoggedIn')){
          return redirect()->to('/dashboard');
        }
    }

    //--------------------------------------------------------------------

    public function after(RequestInterface $request, ResponseInterface $response)
    {
        // Do something here
    }
}
?>

<?php namespace App\Filters;

use CodeIgniter\HTTP\RequestInterface;

use CodeIgniter\HTTP\ResponseInterface;

use CodeIgniter\Filters\FilterInterface;

class Noauth implements FilterInterface

{

public function before(RequestInterface $request)

{

// Do something here

if(session()->get('isLoggedIn')){

return redirect()->to('/dashboard');

}

//--------------------------------------------------------------------

public function after(RequestInterface $request, ResponseInterface $response)

{

// Do something here

}

app/Filters/UsersCheck.php

<?php namespace App\Filters;

use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use CodeIgniter\Filters\FilterInterface;

class UsersCheck implements FilterInterface
{
    public function before(RequestInterface $request)
    {
        // Do something here
        // If segment 1 == login
        //we have to redirect the request to the second segment
        $uri = service('uri');
        if($uri->getSegment(1) == 'login'){
          if($uri->getSegment(2) == '')
            $segment = '/';
          else
            $segment = '/'.$uri->getSegment(2);

          return redirect()->to($segment);

        }
    }

    //--------------------------------------------------------------------

    public function after(RequestInterface $request, ResponseInterface $response)
    {
        // Do something here
    }
}
?>

<?php namespace App\Filters;

use CodeIgniter\HTTP\RequestInterface;

use CodeIgniter\HTTP\ResponseInterface;

use CodeIgniter\Filters\FilterInterface;

class UsersCheck implements FilterInterface

{

public function before(RequestInterface $request)

{

// Do something here

// If segment 1 == login

//we have to redirect the request to the second segment

$uri = service('uri');

if($uri->getSegment(1) == 'login'){

if($uri->getSegment(2) == '')

$segment = '/';

else

$segment = '/'.$uri->getSegment(2);

return redirect()->to($segment);

}

//--------------------------------------------------------------------

public function after(RequestInterface $request, ResponseInterface $response)

{

// Do something here

}

app/config/Filters.php
Once you have created your filters then we need to configure them in app/Config/Filters.php.

<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class Filters extends BaseConfig
{
	// Makes reading things below nicer,
	// and simpler to change out script that's used.
	public $aliases = [
		'csrf'     => \CodeIgniter\Filters\CSRF::class,
		'toolbar'  => \CodeIgniter\Filters\DebugToolbar::class,
		'honeypot' => \CodeIgniter\Filters\Honeypot::class,
		'auth' => \App\Filters\Auth::class,
		'noauth' => \App\Filters\Noauth::class,
		'userscheck' => \App\Filters\UsersCheck::class,
	];

	// Always applied before every request
	public $globals = [
		'before' => [
			'userscheck'
			//'honeypot'
			// 'csrf',
		],
		'after'  => [
			'toolbar',
			//'honeypot'
		],
	];

	// Works on all of a particular HTTP method
	// (GET, POST, etc) as BEFORE filters only
	//     like: 'post' => ['CSRF', 'throttle'],
	public $methods = [];

	// List filter aliases and any before/after uri patterns
	// that they should run on, like:
	//    'isLoggedIn' => ['before' => ['account/*', 'profiles/*']],
	public $filters = [];
}
?>

<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class Filters extends BaseConfig

{

// Makes reading things below nicer,

// and simpler to change out script that's used.

public $aliases = [

'csrf' => \CodeIgniter\Filters\CSRF::class,

'toolbar' => \CodeIgniter\Filters\DebugToolbar::class,

'honeypot' => \CodeIgniter\Filters\Honeypot::class,

'auth' => \App\Filters\Auth::class,

'noauth' => \App\Filters\Noauth::class,

'userscheck' => \App\Filters\UsersCheck::class,

];

// Always applied before every request

public $globals = [

'before' => [

'userscheck'

//'honeypot'

// 'csrf',

'after' => [

'toolbar',

//'honeypot'

];

// Works on all of a particular HTTP method

// (GET, POST, etc) as BEFORE filters only

// like: 'post' => ['CSRF', 'throttle'],

public $methods = [];

// List filter aliases and any before/after uri patterns

// that they should run on, like:

// 'isLoggedIn' => ['before' => ['account/*', 'profiles/*']],

public $filters = [];

}

Define The Route

Add the following route code in the “app/config/Routes.php” file.

$routes->setDefaultNamespace('App\Controllers');
$routes->setDefaultController('Login');
$routes->setDefaultMethod('index');
$routes->setTranslateURIDashes(false);
$routes->set404Override();
$routes->setAutoRoute(true);


$routes->get('/', 'Login::index', ['filter' => 'noauth']);
$routes->get('logout', 'Login::logout');
$routes->match(['get','post'],'register', 'Login::register', ['filter' => 'noauth']);
$routes->get('dashboard', 'Dashboard::index',['filter' => 'auth']);

$routes->setDefaultNamespace('App\Controllers');

$routes->setDefaultController('Login');

$routes->setDefaultMethod('index');

$routes->setTranslateURIDashes(false);

$routes->set404Override();

$routes->setAutoRoute(true);

$routes->get('/', 'Login::index', ['filter' => 'noauth']);

$routes->get('logout', 'Login::logout');

$routes->match(['get','post'],'register', 'Login::register', ['filter' => 'noauth']);

$routes->get('dashboard', 'Dashboard::index',['filter' => 'auth']);

Create view Files

here in this step, we need to create a new default.php, login.php, register.php, and dashboard.php files into the views directory. for that, you can see the below example.

app/views/layouts/default.php
