MODEL
App::uses('AuthComponent','Controller/Component');
class User extends AppModel {
public $validate = array(
'email' => 'email',
'email' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'Please enter a valid email address for username',
'unique' => array(
'rule' => 'isUnique',
'message' => 'Please enter another email, this one is already taken'
)
)
),
'password' => array(
'required'=> array(
'rule' => array('notEmpty'),
'message' => 'Please enter a valid password',
'rule' => array('minLength','8'),
'message' => 'Please enter minimum 8 characters'
)
)
);
public function beforeSave($options = array()) {
if (isset($this->data[$this->alias]['password'])) {
$this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']);
}
return true;
}
}
**CONTROLLER**
<?php
class usersController extends AppController
{
public function beforeFilter() {
parent::beforeFilter();
$this->Auth->allow('add');
}
var $name = 'Users';
public function add()
{
if (!empty($this ->data))
{
$this->User->create();
if ($this->User->save($this->data))
{
$this->Session->setFlash('Thank you for registering');
$this->redirect(array('action'=>'index'));
}
else
{
// Make the password fields blank
unset($this->data['User']['password']);
unset($this->data['User']['confirm_password']);
$this->Session->setFlash('An error occurred, try again!');
}
}
}
function index()
{
}
public function login() {
if ($this->request->is('post')) {
if ($this->Auth->login()) {
return $this->redirect($this->Auth->redirectUrl());
}
$this->Session->setFlash(__('Invalid username or password, try again'));
}
}
public function logout() {
return $this->redirect($this->Auth->logout());
}
}
VIEW

<p>Please fill out details to register</p>
<?php
echo $this->Form->Create('User',array('action' => 'add'));
echo $this->Form->input('title');
echo $this->Form->input('name');
echo $this->Form->input('surname');
echo $this->Form->input('email');
echo $this->Form->input('password');
echo $this->Form->input('password');
echo $this->Form->end('Register');

Answer 1

Your array declarations for your validation rules are wrong.
They have the wrong "level", thus making them invalid.
E.g. email key is used twice.
Please correct them according to the documentation - and using correct 1 tab indentation.
This will make them both correct and readable and easily prevents the mistake you made above.
