cakephp keep data after validation error - php

Question

user data has been lost if there is a validation error and error validation messages are also not showing on front end.
Here is my controller
public function add() {
$this->theme = 'Front';
if (!empty($this->logged_in)) {
return $this->redirect(Router::url('/', true) . $this->logged_in['Role']['alias']);
}
$this->set('title_for_layout', __('Create An Account'));
// hanlde post data
if ($this->request->is("post")) {
if (!empty($this->request->data)) {
$this->User->set($this->request->data);
if (!$this->User->validates()) {
$this->User->validationErrors;
$this->Session->setFlash(__('The Information could not be saved. Please, try again.'), 'message', array('class' => 'danger'));
$this->redirect(Router::url('/', true) . 'sign-up/');
}
}
// die('sdsddsaf');
// if (!empty($this->request->data['User']['role_id']) && $this->request->data['User']['role_id'] == 2) {
unset($this->request->data['User']['specialization_id']);
$randomSt = $this->Custom->randomString(28);
$this->request->data['User']['activation_key'] = $randomSt;
// }
if ($this->User->save($this->request->data)) {
$user = $this->request->data;
if (!empty($this->request->data['User']['role_id']) && $this->request->data['User']['role_id'] == 3) {
$this->Session->setFlash(__('Thank you for registering with us. Please check your email inbox/junk.'), 'message', array('class' => 'successs'));
// set mail variable
$to = $this->request->data['User']['email'];
$fname = $this->request->data['User']['first_name'];
$lname = $this->request->data['User']['last_name'];
//$activelink = SITEURL . 'activate?code=' . $randomSt;
$siteurl = Configure::read('Site.title');
$replace = array($fname, $lname, $siteurl);
// Send mail on Registration
$this->sendMail($to, 'RegisterDoctor', $replace);
} else {
$this->Session->setFlash(__('Thank you for registering with us. Please check your e-mail inbox/junk as your e-mail confirmation has just been sent.'), 'message', array('class' => 'successs'));
$activelink = Router::url('/', true) . 'activate/' . $this->User->id . '/' . $randomSt;
// set mail variable
$to = $this->request->data['User']['email'];
$fname = $this->request->data['User']['first_name'];
$lname = $this->request->data['User']['last_name'];
//$activelink = SITEURL . 'activate?code=' . $randomSt;
$siteurl = Configure::read('Site.title');
$replace = array($fname, $lname, $activelink, $siteurl);
// Send mail on Registration
$this->sendMail($to, 'Register', $replace);
}
$this->redirect(array('controller' => 'users', 'action' => 'login'));
}
}
$reponse = array();
$roles = $this->User->rolesSignup();
$genders = $this->User->genders();
$specializations = $this->User->specializations();
$this->set(compact('roles', 'genders', 'specializations'));
}
And below is my view
<?php

it was working before bu suddenly stop to showing error and start loosing data.
I have check with this question but it is pointing out at field names in input and I have correct ones.
Any help appreciate.

Answer 1

You lost your data because there is redirect to sign-up url.
$this->redirect(Router::url('/', true) . 'sign-up/');
And after redirection
$this->request->data
is empty because you perform new request, the same with errors

Answer 2

According to your code there are two mistakes I found
you are using ! for validating the validations
Save method itself validate the data so no need to validate again.
So your code should be look like
if ($this->User->save($this->request->data)) {
//your code
}else{
$this->Session->setFlash(__('The Information could not be saved. Please, try again.'), 'message', array('class' => 'danger'));
$this->redirect(Router::url('/', true) . 'sign-up/');
}
and validation error messages are automatically assign to view, no need to worry about them
