CakePHP 3 : default validation not working - validation

Question

I am working in CakePHP 3.2. I have users table and register action in UsersController.
I'm trying to add a new record but default validation is not working.
This is my 'UsersTable.php`
<?php
namespace App\Model\Table;
use App\Model\Entity\User;
use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\ORM\Table;
use Cake\Auth\DefaultPasswordHasher;
use Cake\Validation\Validator;
class UsersTable extends Table
{
/**
* Initialize method
*
* #param array $config The configuration for the Table.
* #return void
*/
public function initialize(array $config)
{
parent::initialize($config);
$this->table('users');
$this->displayField('name');
$this->primaryKey('id');
$this->addBehavior('Timestamp');
$this->hasMany('UserAddresses', [
'foreignKey' => 'user_id'
]);
}
/**
* Default validation rules.
*
* #param \Cake\Validation\Validator $validator Validator instance.
* #return \Cake\Validation\Validator
*/
public function validationDefault(Validator $validator)
{
$validator
->uuid('id')
->allowEmpty('id', 'create');
$validator
->notEmpty('name');
$validator
->email('email')
->notEmpty('email');
$validator
->add('mobile', [
'minLength' => [
'rule' => ['minLength', 10],
'message' => 'Mobile number must be of 10 characters long',
],
'maxLength' => [
'rule' => ['maxLength', 10],
'message' => 'Mobile number must be of 10 characters long',
]
])
->numeric('mobile')
->notEmpty('mobile');
$validator
->notEmpty('password');
$validator
->add('newPassword', [
'compare' => [
'rule' => ['compareWith', 'confirmNewPassword'],
]
])
->notEmpty('newPassword');
$validator
->add('confirmNewPassword', [
'compare' => [
'rule' => ['compareWith', 'newPassword'],
'message' => 'Password does not match'
]
])
->notEmpty('confirmNewPassword');
return $validator;
}
/**

* 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']));
return $rules;
}
public function validationPassword(Validator $validator)
{
$validator
->add('old_password', 'custom', [
'rule' => function($value, $context){
$user = $this->get($context['data']['id']);
if ($user) {
if((new DefaultPasswordHasher)->check($value, $user->password)) {
return true;
}
}
return false;
},
'message' => 'The old password does not match the current password!',
])
->notEmpty('old_password');
$validator
->add('password1', [
'length' => [
'rule' => ['minLength', 6],
'message' => 'The Password have to be at least 6 characters!',
]
])
->add('password1', [
'match' => [
'rule' => ['compareWith', 'password2'],
'message' => 'The passwords does not match!',
]
])
->notEmpty('password1');
$validator
->add('password2', [
'length' => [
'rule' => ['minLength', 6],
'message' => 'The Password have to be at least 6 characters!',
]
])
->add('password2', [
'match' => [
'rule' => ['compareWith', 'password1'],
'message' => 'The passwords does not match!',
]
])
->notEmpty('password2');
return $validator;
}
}
register() method
public function register()
{
// if already logged in, redirect to referer action to prevent new registration
if (!empty($this->Auth->user('id'))) {
return $this->redirect($this->referer());
}
$user = $this->Users->newEntity();
if ($this->request->is('post')) {
// check user exists or not
$userExists = $this->Users->find('all', [
'conditions' => [
'OR' => [
'email' => $this->request->data['email'],
'mobile' => $this->request->data['mobile'],
]
]
]);
if ($userExists->count() > 0) {
$userExists = $userExists->first();
$this->Flash->success(__('It seems you are already registered. Please login using your email or mobile and passowrd'));
return $this->redirect(['controller' => 'Users', 'action' => 'login']);
}
$hash = hash('sha256',date('YmdHis').time());
$user->tmp_hash = $hash;
$user->verified = 0;
$user = $this->Users->patchEntity($user, $this->request->data);
if ($u = $this->Users->save($user)) {
// send verification email
if ($this->sendEmail($user->id, $user->email, $hash, 'register')) {
$this->Flash->registerSuccess(__('Thank you. You need to verify email. Not received verification email ?'), [
'params' => [
'userId' => $user->id
],
['escape' => false]
]);
return $this->redirect(['action' => 'login']);
} else {
$this->Flash->error(__('The user could not be saved. Please, try again.'));
return $this->redirect(['action' => 'login']);
}
}
}
$this->set(compact('user'));
$this->set('_serialize', ['user']);
}
register.ctp view
<?= $this->Form->create(null, ['url' => ['controller' => 'Users', 'action' => 'register'], 'class' => 'regForm']) ?>
<div class="form-group">
<label>Name <?= $this->Form->error('name') ?></label>
<?= $this->Form->input('name', ['class' => 'form-control', 'label' => false, 'placeholder' => 'Enter Your Name', 'title' => 'Please Enter your full name']) ?>
</div>
<div class="form-group">
<label>Email address</label>
<?= $this->Form->input('email', ['label' => false, 'class' => 'form-control', 'placeholder' => 'Enter Email', 'title' => 'Please enter valid email']) ?>
</div>
<div class="form-group">
<label>Mobile</label>
<?= $this->Form->input('mobile', ['label' => false, 'class' => 'form-control', 'placeholder' => 'Mobile Number', 'title' => 'Please enter valid mobile no to receive notifications']) ?>
</div>
<div class="form-group">
<label>Password</label>
<?= $this->Form->input('password', ['label' => false, 'class' => 'form-control', 'placeholder' => 'Password', 'title' => 'Please enter password']) ?>
</div>
<?= $this->Form->button('<i class="fa fa-user"></i> Create and account', ['type' => 'submit', 'class' => 'btn btn-primary', 'escape' => false]) ?>
<?= $this->Form->end() ?>
</div>
When I try to submit form without filling anything, it simply refreshes the form without showing validation error.

Answer 1

In your register.ctp file
$this->Form->create(null, ['url' => ['controller' => 'Users', 'action' => 'register'], 'class' => 'regForm']);
Replace it with
$this->Form->create($user, ['url' => ['controller' => 'Users', 'action' => 'register'], 'class' => 'regForm']);
As per concept of CakePHP v3 you have to pass entity in Form Creation method so it will display form validation error in view.
