Cannot Change String To Date Formate in Symfony 2.7 - php

Question

OK, tried to debug this problem for a few days and now i give up.
I have the followig form builder
Builder
->add('passDate', 'hidden', array('data'=>null, 'empty_data'=> date('Y-m-d',strtotime('1950-10-10'))))
->add('TDVLFirstIssue', 'hidden', array('data'=>null, 'empty_data'=> date('Y-m-d',strtotime('1950-10-10'))))
->add('TDVLExpiryDate', 'hidden', array('data'=>null, 'empty_data'=> date('Y-m-d',strtotime('2017-10-10'))));
and this is my entity
/**
* #var \DateTime
*
* #ORM\Column(name="passDate", type="date")
* #Assert\NotBlank()
*/
private $passDate;
/**
* #var \DateTime
*
* #ORM\Column(name="tdvlIssue", type="date")
* #Assert\NotBlank()
*/
private $TDVLFirstIssue;
/**
* #var \DateTime
*
* #Assert\GreaterThan(value = "+1 day midnight", message="Your TDVL require at least 1 month validity.")
* #ORM\Column(name="tdvlExpiry", type="date")
* #Assert\NotBlank()
*/
private $TDVLExpiryDate;
public function setPassDate($passDate)
{
$this->passDate = $passDate;
return $this;
}
/**
* Get passDate
*
* #return \DateTime
*/
public function getPassDate()
{
return $this->passDate;
}
public function setTDVLFirstIssue($tDVLFirstIssue)
{
$this->TDVLFirstIssue = $tDVLFirstIssue;
return $this;
}
/**
* Get tDVLFirstIssue
*
* #return \DateTime
*/
public function getTDVLFirstIssue()
{
return $this->TDVLFirstIssue;
}
**
* Set tDVLExpiryDate
*
* #param \DateTime $tDVLExpiryDate
*
* #return User
*/
public function setTDVLExpiryDate($tDVLExpiryDate)
{
$this->TDVLExpiryDate = $tDVLExpiryDate;
return $this;
}
/**
* Get tDVLExpiryDate
*
* #return \DateTime
*/
public function getTDVLExpiryDate()
{
return $this->TDVLExpiryDate;
}
And here is my controller
$entity = new User();
$form = $this->createSystemUserForm($entity);
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$entity->setTDVLFirstIssue(date('Y-m-d',strtotime('1950-10-10')));
$entity->setTDVLExpiryDate(date('Y-m-d',strtotime('2018-10-10')));
$entity->setPassDate(date('Y-m-d',strtotime('1950-10-10')));
}
What i am trying to do is i want to pass default date to the database. so i tried with vanilla php format converting function data and format . But when i submit the form, it throw me this error which is
Error: Call to a member function format() on string
public function convertToDatabaseValue($value, AbstractPlatform $platform)
{
return ($value !== null)
? $value->format($platform->getDateFormatString()) : null;
}
. I understood that $passDate, $TDVLFirstIssue and $TDVLExpiryDate cannot be blank , which defined in entity as NotBlank(). I suspect that it is because of unsuccessful string to date conversion. So can help me about this problem? thanks in advance.
Note: Please take note that i am using symfony 2.7.

I change my builder date as follow and it works.
builder
->add('passDate', 'hidden', array('data'=>null, 'empty_data'=> date_create('1950-10-10')))
->add('TDVLFirstIssue', 'hidden', array('data'=>null, 'empty_data'=> date_create('1950-10-10')))
->add('TDVLExpiryDate', 'hidden', array('data'=>null, 'empty_data'=> date_create('2017-10-10')));
Hope it helps.
