Zend Form Duplicate Entry Email Exception - php

Question

Having a registration zend form in view looks like this :
<?php
$form = $this->form;
if(isset($form)) $form->prepare();
$form->setAttribute('action', $this->url(NULL,
array('controller' => 'register', 'action' => 'process')));
echo $this->form()->openTag($form);
?>
<dl class="form-signin">
<dd><?php
echo $this->formElement($form->get('name_reg'));
echo $this->formElementErrors($form->get('name_reg'));
?></dd>
<dd><?php
echo $this->formElement($form->get('email_reg'));
echo $this->formElementErrors($form->get('email_reg'));
?></dd>
<dd><?php
echo $this->formElement($form->get('password_reg'));
echo $this->formElementErrors($form->get('password_reg'));
?></dd>
<dd><?php
echo $this->formElement($form->get('confirm_password_reg'));
echo $this->formElementErrors($form->get('confirm_password_reg'));
?></dd>
<br>
<dd><?php
echo $this->formElement($form->get('send_reg'));
echo $this->formElementErrors($form->get('send_reg'));
?></dd>
<?php echo $this->form()->closeTag() ?>
And RegisterController as following.
<?php
namespace Test\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Zend\Session\Container;
use Test\Form\RegisterForm;
use Test\Form\RegisterFilter;
use Test\Form\LoginFormSm;
use Test\Form\LoginFilter;
use Test\Model\User;
use Test\Model\UserTable;
class RegisterController extends AbstractActionController
{
public function indexAction()
{
$this->layout('layout/register');
$form = new RegisterForm();
$form_sm = new LoginFormSm();
$viewModel = new ViewModel(array(
'form' => $form,
'form_sm' =>$form_sm,
));
return $viewModel;
}
public function processAction()
{
$this->layout('layout/register');
if (!$this->request->isPost()) {
return $this->redirect()->toRoute(NULL,
array( 'controller' => 'index'
)
);
}
$form = $this->getServiceLocator()->get('RegisterForm');
$form->setData($this->request->getPost());
if (!$form->isValid()) {
$model = new ViewModel(array(
'form' => $form,
));
$model->setTemplate('test/register/index');
return $model;
}
// Creating New User
$this->createUser($form->getData());
return $this->redirect()->toRoute(NULL, array (
'controller' => 'auth' ,
));
}
protected function createUser(array $data)
{
$userTable = $this->getServiceLocator()->get('UserTable');
$user = new User();
$user->exchangeArray($data);
$userTable->saveUser($user);
return true;
}
}
Also a RegisterForm where are declared all variables shown in index. Also RegisterFilter as following:
<?php
namespace Test\Form;
use Zend\InputFilter\InputFilter;
class RegisterFilter extends InputFilter
{
public function __construct()
{
$this->add(array(
'name' => 'email_reg',
'required' => true,
'filters' => array(
array(
'name' => 'StripTags',
),
array(
'name' => 'StringTrim',
),
),
'validators' => array(
array(
'name' => 'EmailAddress',
'options' => array(
'domain' => true,
'messages' => array(
\Zend\Validator\EmailAddress::INVALID_FORMAT => 'Email address format is invalid'
),
),
),
array(
'name' => 'AbstractDb',
'options' => array(
'domain' => true,
'messages' => array(
\Zend\Validator\Db\AbstractDb::ERROR_RECORD_FOUND => 'Current Email Already registered'
),
),
),
),
));
$this->add(array(
'name' => 'name_reg',
'required' => true,
'filters' => array(
array(
'name' => 'StripTags',
),
array(
'name' => 'StringTrim',
),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 2,
'max' => 140,
),
),
),
));
$this->add(array(
'name' => 'password_reg',
'required' => true,
'validators' => array(
array(
'name' => 'StringLength',
'options' =>array(
'encoding' => 'UTF-8',
'min' => 6,
'messages' => array(
\Zend\Validator\StringLength::TOO_SHORT => 'Password is too short; it must be at least %min% ' . 'characters'
),
),
),
array(
'name' => 'Regex',
'options' =>array(
'pattern' => '/[A-Z]\d|\d[A-Z]/',
'messages' => array(
\Zend\Validator\Regex::NOT_MATCH => 'Password must contain at least 1 digit and 1 upper-case letter'
),
),
),
),
));
$this->add(array(
'name' => 'confirm_password_reg',
'required' => true,
'validators' => array(
array(
'name' => 'Identical',
'options' => array(
'token' => 'password_reg', // name of first password field
'messages' => array(
\Zend\Validator\Identical::NOT_SAME => "Passwords Doesn't Match"
),
),
),
),
));
}
}
Problem
All i need is to throw a message when somebody tries to register and that e-mail is already registered. Tried with \Zend\Validator\Db\AbstractDb and added following validator to email in RegisterFilter as following
array(
'name' => 'AbstractDb',
'options' => array(
'domain' => true,
'messages' => array(
\Zend\Validator\Db\AbstractDb::ERROR_RECORD_FOUND => 'Current Email Already registered'
),
),
),
But that seems not to work.
Question: Is there a way to implement this validator in RegisterController?
Additional.
I've deleted from RegisterFilert validator and put inside Module.ph
'EmailValidation' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$validator = new RecordExists(
array(
'table' => 'user',
'field' => 'email',
'adapter' => $dbAdapter
)
);
return $validator;
},
And call it from RegisterController
$validator = $this->getServiceLocator()->get('EmailValidation');
if (!$validator->isValid($email)) {
// email address is invalid; print the reasons
$model = new ViewModel(array(
'error' => $validator->getMessages(),
'form' => $form,
));
$model->setTemplate('test/register/index');
return $model;
}
And when i use print_r inside view to check for it shows.
Array ( [noRecordFound] => No record matching the input was found ).
I want just to echo this 'No record matching the input was found'.
Fixed
Modified in RegisterController as following
$validator = $this->getServiceLocator()->get('EmailValidation');
$email_ch = $this->request->getPost('email_reg');
if (!$validator->isValid($email_ch)) {
// email address is invalid; print the reasons
$model = new ViewModel(array(
'error' => 'Following email is already registered please try another one',
'form' => $form,
));
$model->setTemplate('test/register/index');
return $model;
}
I had compared
if (!$validator->isValid($email_ch))
Before with nothing and that's why i needed to add first
$email_ch = $this->request->getPost('email_reg');

Answer 1

You don't have to do that in your controller, just try this in your RegisterFilter class :
First : Add $sm as parameter of the _construct() method :
public function __construct($sm) {....}
Second: Replace e-mail validation by this one :
$this->add ( array (
'name' => 'email_reg',
'required' => true,
'validators' => array(
array(
'name' => 'Zend\Validator\Db\NoRecordExists',
'options' => array(
'table' => 'user',
'field' => 'email',
'adapter' => $sm->get ( 'Zend\Db\Adapter\Adapter' ),
'messages' => array(
NoRecordExists::ERROR_RECORD_FOUND => 'e-mail address already exists'
),
),
),
),
)
);
When you call the RegisterFilter don't forget to pass the serviceLocator as parameter in your controller :
$form->setInputFilter(new RegisterFilter($this->getServiceLocator()));
Supposing you have this in your global.php File (config\autoload\global.php) :
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
),
),

To your previous request, ("I want just to echo this 'No record matching the input was found'")
$validator = $this->getServiceLocator()->get('EmailValidation');
$email_ch = $this->request->getPost('email_reg');
if (!$validator->isValid($email_ch)) {
// email address is invalid; print the reasons
foreach ($validator->getMessages() as $message) {
$msg = $message;
}
$model = new ViewModel(array(
'error' => $msg,
'form' => $form,
));
$model->setTemplate('test/register/index');
return $model;
}
