Can I access discriminator field from php in doctrine2?

Question

I have an entity which defines inheritance like this:

* @DiscriminatorColumn(name=\"type\", type=\"string\")
* @DiscriminatorMap({\"text\" = \"TextAttribute\         


        

Answer 1

Another slicker and faster way than to overload the method in every child or define a constant in every child is to use reflection class to retrieve the name of the class without the namespace :

public function getType() {
    return (new \ReflectionClass($this))->getShortName();
}

It also works in any php version since php 5

It might not return exactly the discriminator name depending on your discriminator map declaration but it will return the child entity name (the class name) which is a great way to name and distinguish the different subentities

Without a need to define anything in the subclasses.

Answer 2

It's possible either with the EntityManager or using the DocumentManager.

$documentManager->getClassMetadata(get_class($entity))->discriminatorValue;
