I would like to create one form to enter the following data:

nombre (nombre in Cliente entity)

nombre (nombre in Contacto entity)

idcliente (idcliente in Contacto entity)(same stored value that the client entity)

Answer 1

The idcliente is unique

Relationship

My concept of form in twig is so:

{{ form_start(form) }}
<p>Nombre: {{ form_widget(form.nombre) }}</p>
<p>Nombre Contacto: {{ form_widget(form.nombrecontacto) }}</p>
{{ form_widget(form.Guardar) }}
{{ form_end(form) }}

My concept in controller is so:

public function inicioAction(Request $request)
    {
        $em = $this->getDoctrine()->getManager();

        $clientes  = $em->createQuery("SELECT DISTINCT CLI.idcliente
                        FROM GeneralBundle:Cliente CLI
                        WHERE CLI.idcliente = CON.idcliente)->getResult();
        $numclientes = count($clientes);
        $idnew = $numclientes+1;
        $cliente = new Cliente();
        $contacto = new Contacto();

        $form = $this->createform(**¿¿ Here is the question ??**); 

        if ($form->isValid())
        {
            $em = $this->getDoctrine()->getManager();
            $cliente->setIdcliente($idnew);
            $em->persist($cliente);
            $em->flush();

            $em = $this->getDoctrine()->getManager();
            $contacto->setIdcliente($idnuevo);
            $em->persist($contacto);
        }
    }
