Doctrine - Add default time stamp to entity like NOW()

Ok I found the solution:

• https://doctrine-orm.readthedocs.org/en/latest/reference/php-mapping.html?highlight=callback
• http://doctrine-orm.readthedocs.org/en/latest/reference/events.html#lifecycle-events

The prePersist option is what I'm doing.

Make sure you define in the annotations

<?php

/** @Entity 
 *  @HasLifecycleCallbacks 
 */
class User

and here is the function example they offer

/** 
 *  @PrePersist 
 */
public function doStuffOnPrePersist()
{
    $this->createdAt = date('Y-m-d H:i:s');
}

And if you're using ORM like I am

<?php

/** @ORM\Entity 
 *  @ORM\HasLifecycleCallbacks 
 */
class User

and here is the function example they offer

/** 
 *  @ORM\PrePersist 
 */
public function doStuffOnPrePersist()
{
    $this->createdAt = date('Y-m-d H:i:s');
}

In my experience it is best to put everything in your Entities and not try to force your database to bypass the ORM.

<?php
namespace Phill\PaffordBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
 * Stack
 * @ORM\Table()
 */
class Stack
{
  /**
   * @var integer
   * @ORM\Column(type="integer")
   * @ORM\Id
   * @ORM\GeneratedValue(strategy="AUTO")
   */
  private $id;

  /**
   * @var \DateTime
   * @ORM\Column(type="datetime")
   */
  private $startDate;

  public function __construct()
  {
    $this->startDate = new \DateTime();
  }

}
