This chapter deals with the information about the authentication process available in CakePHP.

CakePHP Services

CakePHP Services is the process of identifying the correct user. CakePHP supports three types of authentication.

  • FormAuthenticate − It allows you to authenticate users based on form POST data. Usually, this is a login form that users enter information into. This is default authentication method.

  • BasicAuthenticate − It allows you to authenticate users using Basic HTTP authentication

  • DigestAuthenticate − It allows you to authenticate users using Digest HTTP authentication.

Example for FormCakePHP Services

Make changes in the config/routes.php file as shown in the following code.

config/routes.php

<?php use Cake\Core\Plugin;
use Cake\Routing\RouteBuilder;
use Cake\Routing\Router;
Router::defaultRouteClass('DashedRoute');
Router::scope('/', function (RouteBuilder $routes) {
   $routes->connect('/auth',['controller'=>'Authexs','action'=>'index']);
   $routes->connect('/login',['controller'=>'Authexs','action'=>'login']);
   $routes->connect('/logout',['controller'=>'Authexs','action'=>'logout']);
   $routes->fallbacks('DashedRoute');
});
Plugin::routes();

Change the code of AppController.php file as shown in the following program.

src/Controller/AppController.php

<?php namespace App\Controller;
use Cake\Controller\Controller;
use Cake\Event\Event;
use Cake\Controller\Component\AuthComponent;
class AppController extends Controller {
   public function initialize() {
      parent::initialize();
      $this->loadComponent('RequestHandler');
      $this->loadComponent('Flash');
         $this->loadComponent('Auth', [
            'authenticate' => [
               'Form' => [
                  'fields' => [
               'username' => 'username',
               'password' => 'password'
            ]
         ]
      ],
      'loginAction' => [
         'controller' => 'Authexs',
         'action' => 'login'
      ],
      'loginRedirect' => [
         'controller' => 'Authexs',
         'action' => 'index'
      ],
      'logoutRedirect' => [
         'controller' => 'Authexs',
         'action' => 'login'
      ]
   ]);
}
public function beforeFilter(Event $event) {
      $this->Auth->allow(['index','view']);
      $this->set('loggedIn', $this->Auth->user());
   }
}

Create AuthexsController.php file at src/Controller/AuthexsController.php. Copy the following code in the controller file.

src/Controller/AuthexsController.php

<?php namespace App\Controller;
use App\Controller\AppController;
use Cake\ORM\TableRegistry;
use Cake\Datasource\ConnectionManager;
use Cake\Event\Event;
use Cake\Auth\DefaultPasswordHasher;
class AuthexsController extends AppController {
   var $components = array('Auth');
   public function index(){
   }
   public function login(){
      if($this->request->is('post')) {
         $user = $this->Auth->identify();
         if($user){
            $this->Auth->setUser($user);
            return $this->redirect($this->Auth->redirectUrl());
         } else
         $this->Flash->error('Your username or password is incorrect.');
      }
   }
   public function logout(){
      return $this->redirect($this->Auth->logout());
   } 
}
?>

Create a directory Authexs at src/Template and under that directory create a View file called login.php. Copy the following code in that file.

src/Template/Authexs/login.php

<?php echo $this->Form->create();
   echo $this->Form->control('username');
   echo $this->Form->control('password');
   echo $this->Form->button('Submit');
   echo $this->Form->end();
?>

Create another View file called logout.php. Copy the following code in that file.

src/Template/Authexs/logout.php

You are successfully logged out.

Create another View file called index.php. Copy the following code in that file.

src/Template/Authexs/index.php

You are successfully logged in. 
<?php echo $this->Html->link('logout',[
      "controller" => "Authexs","action" => "logout"
   ]); 
?>

Execute the above example by visiting the following URL.

http://localhost/cakephp4/auth

Output

As the authentication has been implemented, and once you try to visit the above URL, you will be redirected to the login page as shown below.

CakePHP Services

After providing the correct credentials, you will be logged in and redirected to the screen as shown below.

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
