Question

You know that in Symfony2 a new entity can be defined as in the following example:

use Acme\StoreBundle\Entity\Product;

public function defaultController() {
    $product = new Product();
    $product->setName('Pippo');
    $product->setPrice(19.99);
    ....
    // Use Doctrine EntityManager to store the Product object
}

Suppose that you know that the Product class has the following namespace: “AcmeHomeBundle:Product“. It would by nice to create the $product object by using the namespace (e.g. by using the EntityManager or something similar).

public function defaultController() {
    $item = createObjectFromNamespace("AcmeHomeBundle:Product");
    $item->setName('Pippo');
    $item->setPrice(19.99);
    ....
    // Use Doctrine EntityManager to store the Item object
}

Do you know if this is possible?

Suppose that you have a string that provides the entity type

Answer 1

You should do this…

$entityInfo = $this->em->getClassMetadata("entityNameSpace:entityName");
$entityMember = $entityInfo->newInstance();

If you wanna use a setter method by string:

$entitySetMethod = "set".\ucfirst("entityDataMemberName");
\call_user_func(array($entityMember, $entitySetMethod), $parameter);
