Here is my code of Form/UsersType.php

<?php
namespace Acme\DemoBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;


class UsersType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('username','text', array('required' => true))
            ->add('firstname','text', array('required' => true))
            ->add('lastname','text', array('required' => true))
            ->add('email', 'email', array('label' => 'E-Mail'))
            ->add('password', 'password', array('label' => 'Password'))
            ->add('password_confirmation', 'password', array('mapped' => false)) // Added virtual field on form
/*                
            ->add('active','hidden',array('data' => ''))
            ->add('created','hidden',array('data' => ''))
            ->add('modified','hidden',array('data' => ''))
 * 
 */
        ;        
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Acme\DemoBundle\Entity\Users'
        ));
    }

    public function getName()
    {
        return 'acme_demobundle_userstype';
    }
}

I have commented out these three fields active, created and modified to not display them in the form.

But i am getting error:

An exception occurred while executing 'INSERT INTO users (username, firstname, lastname, email, password, active, created, modified) VALUES (?, ?, ?, ?, ?, ?, ?, ?)' with params ["neeraj", "neeraj", "kumar", "[e-mail]", "p@ssw0rd", null, null, null]:

What i am missing in the Entity?

Answer 1

@ORM\PrePersist is missing parenthesis, it should be @ORM\PrePersist()

Answer 2

I solved this issue cleaning the cache!

php bin/console cache:clear

Answer 3

I have the same problem. According to docs you must enable lifecycle callbacks http://symfony.com/doc/current/book/doctrine.html

/**
 * @ORM\Entity()
 * @ORM\HasLifecycleCallbacks()
 */
class Product
{
    // ...
}

Answer 4

One issue is this function.

/**
 * Set active
 *
 * @ORM\PrePersist
 * @param boolean $active
 * @return Users
 */
public function setActive($active)
{
    $this->active = $active;

    return $this;
}

You can't pass arguments to functions when using @PrePersist.

Also this function

/**
* @ORM\PrePersist
* @ORM\PreUpdate
*/
public function prePersist(){

  $this->active = 0;
  $this->created = date('Y-m-d H:i:s');
  $this->modified = date('Y-m-d H:i:s');

}

fails because you are assigning a string value to DateTime fields. Try this:

/**
 * @ORM\PrePersist
 * @ORM\PreUpdate
 */
public function prePersist()
{

  $this->active = false;
  $this->created = new \DateTime();
  $this->modified = new \DateTime();

}
