Doctrine 2: how to clone all values from one object onto another except ID?

Question

In $entity variable, there is an object of same type as $other_address, but with all field values filled in.

I want to set all fields in $other_address object to have exact same values as $entity object.

Is this doable in less then N number of lines, where N is number of fields I need to set?

I tried "clone" keyword, but it didnt work.

Here's the code.

                $other_address = $em->getRepository('PennyHomeBundle:Address')
          ->findBy(array('user' => $this->get('security.context')->getToken()->getUser()->getId(), 'type' => $check_type));
                $other_address = $other_address[0];


                //I want to set all values in this object to have values from another object of same type
                $other_address->setName($entity->getName());
                $other_address->setAddress1($entity->getAddress1());
                $other_address->setAddress2($entity->getAddress2());
                $other_address->setSuburbTown($entity->getSuburbTown());
                $other_address->setCityState($entity->getCityState());
                $other_address->setPostZipCode($entity->getPostZipCode());
                $other_address->setPhone($entity->getPhone());
                $other_address->setType($check_type);

I'm not sure why cloning won't work.

This seems to work for me, at least in a basic test case:

$A = $em->find('Some\Entity',1);

$B = clone $A;
$B->setId(null);

If you've got relationships to worry about, you might want to safely implement __clone so it does what you want it to do with related entities.

As DavidLin points, you don't have to "unset" the entity ID (if the field is properly marked as ID) – Sergi Aug 08 '13 at 11:33
HI @timdev, what if i wanted to copy, assume i have a temp object and i need to merge that it in original object? is that possible? – senK Dec 24 '14 at 09:59

Just Clone the entity, you don't even need to unset the id. Doctrine has tackled this for you

It seems that if you use your own ID generators the ID isn't set to null. Even if the ID field is marked as being an ID. – flu Apr 09 '14 at 07:54

$A = $em->find('Some\Entity',1);

$B = clone $A;
$em->persist($B);
$em->flush();

if you merge it will update the entity, best you use persist() it will duplicate the entire row and add auto incremented primary key
