Finding out what changed via postUpdate listener in Symfony 2.1

Question

I have a postUpdate listener and I\'d like to know what the values were prior to the update and what the values for the DB entry were after the update. Is there a way to do this

Answer 1

You can find example in doctrine documentation.

class NeverAliceOnlyBobListener
{
    public function preUpdate(PreUpdateEventArgs $eventArgs)
    {
        if ($eventArgs->getEntity() instanceof User) {
            if ($eventArgs->hasChangedField('name') && $eventArgs->getNewValue('name') == 'Alice') {
                $eventArgs->setNewValue('name', 'Bob');
            }
        }
    }
}
