login and registration with Cakephp 3 tutorial

Create login and registration with Cakephp 3


first you need to install cakephp 3 on your localhost or sever .for installation guide read this post Install Cakephp 3+ without composer on localhost





Step 1

  open your appController.php (Location :- C://xampp/htdocs/yourproject/src/Controller)
  and paste this code into initialize function.

public function initialize()
    {

        $this->set('pageMainHeading', 'Admin');
        $this->set('title_for_layout','Admin');
        $this->viewBuilder()->layout('default');
        $this->loadComponent('Flash');

        $this->loadComponent('Auth', [
            'loginRedirect' => [
                'controller' => 'AdminUsers',
                'action' => 'index'
            ],
            'logoutRedirect' => [
                'controller' => 'Pages',
                'action' => 'display',
                'home'
            ],
            'loginAction' => [
            'controller' => 'AdminUsers',
            'action' => 'login',
           
        ],
        ]);
    
    }

Step 2
now we create our login controller .create a new file  AdminUsersController.php
and create login registration fuinction into it ...or paste this code.

        $this->Flash->success(__($msg),'default',array('class' => 'alert alert-success'));
        return $this->redirect(array('action' => $action));
    }

 


}

Step 2--
Now we create a model for our controller
create a new file AdminUsersTable.php (Location :- C://xampp/htdocs/yourproject/src/Model/Table)

<?php
// Path File: \App\src\Model\Table\UsuariosTable.php
namespace App\Model\Table;



use App\Model\Entity\AdminUser;
use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\ORM\Table;
use Cake\Validation\Validator;
use Cake\Event\Event;

/**
 * AdminUser Model
 *
 * @property \Cake\ORM\Association\BelongsTo $Perfiles
 */
class AdminUsersTable extends Table
{

    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config)
    {
        parent::initialize($config);
        $this->primaryKey('id');

   }  


    public function validationDefault(Validator $validator)
    {
        return $validator;
           
           
    }

    /**
     * Returns a rules checker object that will be used for validating
     * application integrity.
     *
     * @param \Cake\ORM\RulesChecker $rules The rules object to be modified.
     * @return \Cake\ORM\RulesChecker
     */
 
   public function buildRules(RulesChecker $rules)
    {
        $rules->add($rules->isUnique(['email']));
        $rules->add($rules->isUnique(['username']));
        //$rules->add($rules->existsIn(['perfiles_id'], 'Perfiles'));
        return $rules;
    }

    }

}


Step 3
to convert password into hash we create an entity AdminUser.php (Location :- C://xampp/htdocs/yourproject/src/Model/Entity/AdminUser.php)

<?php
// src/Model/Entity/User.php
namespace App\Model\Entity;

use Cake\Auth\DefaultPasswordHasher;
use Cake\ORM\Entity;

class AdminUser extends Entity
{

    // Make all fields mass assignable except for primary key field "id".
    protected $_accessible = [
        '*' => true,
        'id' => false
    ];

    // ...

    protected function _setPassword($password)
    {
        return (new DefaultPasswordHasher)->hash($password);
    }



    // ...
}

?>



Step 4 Now create views for our controller
Navigate to c://xampp/htdocs/yourproject/src/template/
create a new folder with AdminUsers name

then create these files into it









 login.ctp
<div class="wrapper">
        <div class="container">
            <div class="row">
                <div class="module module-login span4 offset4">
                   
                   
                    <?= $this->Form->create() ?>
                        <div class="module-head">
                            <h3>Sign In</h3>
                           
                        </div>
                        <div class="module-body">

                            <?= $this->Flash->render('auth') ?>
                             <?= $this->Flash->render() ?>
                            <div class="control-group">

                                </div>

                            <div class="control-group">

                                    <?php
echo $this->Form->input('password', array('type' => 'password','class' => 'form-control fullwidth span12 placeholder-no-fix','required' => true,'label' => 'Password','placeholder' => 'Password'));
 ?>
                                </div>
                            </div>
                        </div>
                        <div class="module-foot">
                            <div class="control-group">
                                <div class="controls clearfix">
                                    <button type="submit" class="btn btn-success green pull-right">Login</button>
                                   
                                </div>
                            </div>
                        </div>
                    </form>
                </div>
            </div>
        </div>
    </div><!--/.wrapper-->



add.ctp
<!-- src/Template/Users/add.ctp -->

<div class="users form">
<?= $this->Form->create($user) ?>
<?php
if($aRow){   
    echo $this->Form->input('id', array('type' => 'hidden','value' => $aRow['id']));
}

?>
    <fieldset>
        <legend><?= __('Add User') ?></legend>
        <?= $this->Form->input('username', array('type' => 'text','class' => 'form-control','required' => true,'label' => 'Username')); ?>
        <?= $this->Form->input('email', array('type' => 'text','class' => 'form-control','required' => true,'label' => 'Email')); ?>
        <?= $this->Form->input('password', array('type' => 'text','class' => 'form-control','required' => true,'label' => 'Password')); ?>
        <?php echo $this->Form->input('role', array('class' => 'form-control','required' => true,'empty' => 'Select Role', 'options' => $roles, 'label' => 'Select Role' ,

   </fieldset>
<?= $this->Form->submit('Submit', array('div' => false,'class' => 'btn btn-success', 'title' => 'Add User')); ?>
