CakePHP 3 step registration

Question

I am trying to create a 3 step registration page withh cakePHP. First step is OK, it inserts the data in db but the second step is not working. Can someone help please?

Here is my controller code:

<?php

App::uses('Controller', 'Controller');

class UsersController extends AppController {

public $name = 'Users';

public function beforeFilter(){
    parent::beforeFilter();
    $this->Auth->allow('signup');
}

public function login(){
    if($this->request->is('post')){
        if($this->Auth->login()){
            $this->redirect($this->Auth->redirect());   
        } else {
            $this->Session->setFlash('Invalid username or password!', 'default', array('class' => 'errormsg'));
        }
    }
}
public function logout(){
    $this->redirect($this->Auth->logout());
}
// SIGN UP ACTIONS
public function signup($step = null){
    // SET STEP VARIABLE
    $this->set('s', $step);
    // STEP 1 - REGISTER
    if(empty($step)){
        if ($this->request->is('post')) {
            if ($this->User->save($this->request->data)) {
                $this->Session->write('regUser', $this->request->data['User']['email']);
                // $this->Session->setFlash('The user has been saved, please enter other information!',
                //                          'default', array('class' => 'okormsg'));
                $regUser = $this->User->find(   'first', array('conditions' => array(
                                                'User.username' => $this->Session->read('regUser'))));
                $id = $regUser['User']['id'];

                $this->Session->write('regUserId', $id);

                $this->redirect(array('personal-info'));
            } else {
                $this->Session->setFlash(   'There was an error, please check the fields bellow!',
                                            'default', array('class' => 'errormsg'));
            }
        }
    // STEP 2 - PERSONAL INFORMATION
    } elseif($step == 'personal-info') {
        if ($this->request->is('post')) {
            $id = $this->Session->read('regUserId');
            $this->User->id = $id;

            if ($this->User->save($this->request->data)) {
                $this->Session->setFlash('The user has been saved');
                $this->redirect(array('complete'));
            } else {
                $this->Session->setFlash('User could not be saved. Please, try again.');
            }
        }
    // STEP 3 - COMPLETE REGISTRATION
    } elseif($step == 'complete') {

    }
}
}

?>

Here is the Model:

<?php

class User extends AppModel {

public $validate = array (
    'name'=>array(
        'Please enter your name!'=>array(
            'rule'=>'notEmpty',
            'message'=>'Please enter your name!'
        )
    ),
    'surname'=>array(
        'Please enter your surname!'=>array(
            'rule'=>'notEmpty',
            'message'=>'Please enter your surname!'
        )
    ),
    'email'=>array(
        'Valid email'=>array(
            'rule'=>array('email'),
            'message'=>'Please enter a valid Email address!'
        ),
        'Already exists'=>array(
            'rule'=>'isUnique',
            'message'=>'This Email is already registered in our database!'
        )
    ),
    'password'=>array(
        'Not empty'=>array(
            'rule'=>'notEmpty',
            'message'=>'Please enter your password!'
        ),
        'Match password'=>array(
            'rule'=>'matchPasswords',
            'message'=>'Your passwords do not match!'
        )
    ),
    'password_confirm'=>array(
        'Not empty'=>array(
            'rule'=>'notEmpty',
            'message'=>'Please confirm your password!'
        )
    ),
    'terms'=>array(
        'Agree'=>array(
            'rule'=>'notEmpty',
            'required'=>true,
            'message'=>'You must agree to Terms and conditions!'
        )
    )
);

public function matchPasswords($data){
    if ($data['password'] == $this->data['User']['password_confirm']){
        return true;
    } else {
        $this->invalidate('password_confirm', 'Your passwords do not match!');
        return false;
    }
}
public function beforeSave(){
    if(!empty($this->data['User']['password'])) {
        $this->data['User']['password'] = AuthComponent::password($this->data['User']['password']);
    }
    if (empty($this->data['User']['username'])) {
        $this->data['User']['username'] = $this->data['User']['email'];
    }
    return true;
}
}

?>

And here is the view for signup.ctp

So as I said on first step it's all OK, it saves the user in DB but on second step I would like to put more information and when I submit it displays the Session flash message that User can not be saved, so that means that second user information is not saved in DB.

Please help!

Answer 1

Found solution. There was an error in validating. On second step it tried to validate Terms of Use checkbox. So here is the complete code of 3 STEP REGISTRATION:

USER CONTROLLER:

<?php

App::uses('Controller', 'Controller');

class UsersController extends AppController {

public $name = 'Users';

public function beforeFilter(){
    parent::beforeFilter();
    $this->Auth->allow('signup');
}

public function login(){
    if($this->request->is('post')){
        if($this->Auth->login()){
            $this->redirect($this->Auth->redirect());   
        } else {
            $this->Session->setFlash('Invalid username or password!', 'default', array('class' => 'errormsg'));
        }
    }
}
public function logout(){
    $this->redirect($this->Auth->logout());
}
// SIGN UP ACTIONS
public function signup($step = null){
    // SET STEP VARIABLE
    $this->set('s', $step);
    // STEP 1 - REGISTER
    if(!$step){
        $this->set('r', 1);
        if ($this->request->is('post')) {
            if ($this->User->save($this->request->data)) {
                $this->Session->write('regUser', $this->request->data['User']['email']);
                // $this->Session->setFlash('The user has been saved, please enter other information!',
                //                          'default', array('class' => 'okormsg'));
                $regUser = $this->User->find(   'first', array('conditions' => array(
                                                'User.username' => $this->Session->read('regUser'))));
                $id = $regUser['User']['id'];
                $this->Session->write('regUserId', $id);
                $this->redirect(array('personal-info'));
            } else {

        }
    // STEP 2 - PERSONAL INFORMATION
    } elseif($step == 'personal-info') {

        $this->User->id = $id;
        if ($this->request->is('post')) {
            if ($this->User->save($this->request->data, array('validate' => false))) {
                $this->redirect(array('complete'));
            } else {
                $this->Session->setFlash(   'User could not be saved. Please, try again.',
                                            'default', array('class' => 'errormsg'));
