Yes. Your field name should explain it's value:
public function buildForm(FormBuilderInterface $builder, array $options) { $builder ->add( 'game', EntityType::class, [ 'class' => 'AppBundle:Game', 'choice_label' => 'name', 'label' => 'name' ] ) ->add( 'type', EntityType::class, [ 'class' => 'AppBundle:Type', 'choice_label' => 'name', 'multiple' => false, 'expanded' => false ] ); } Afterwards you can access these fields like:
$form->get('game') // and $form->get('type')

Kinda, it would be something like:
 

class Quote { private $id; // .. other fields private $price; public function setId($id) { $this->id = $id; } public function getId() { return $this->id; } // get*, set* for the other fields public function setPrice($price) { $this->price = $price; } public function getPrice() { return $this->price; } }Then you would create a query and populate this object: 

$sql = 'SELECT id, .., price FROM quotes'; $stmt = $this->db->prepare($sql); foreach ($stmt->fetchAll() as $row) { $quotes[] = $quote = new Quote; $quote->setId($row['id']); $quote->setPrice($row['price']); } return $quotes;At this point you can work with this object as: 

$quote->getId(); $quote->getPrice();Now before you start writing all of this yourself, there are frameworks available online that do this sort of thing for you. A list can be found here:https://github.com/ziadoz/awesome-php#database
