how to handle manytone relations in a form - php

Question

im trying to safe the serials from various products already bought, so i made a relation between the invoice table, serials table and my products table, the relations are shown below.
i already made a form to add the relations between the product_table and invoice_table with the serial_table, the form is adding the relations and the serials, but the user shouldn't be available to choose the relations between the tables, it should find the idproduct and id invoice from the purchase made and store the serials and send it to the database without the user changing it, below is the picture of my form.
this is the formtype from the form above
class serialType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('serial','integer')
->add('idPedido')
->add('idProducto')
->add('agregar serial','submit')
;
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'sava\InventarioBundle\Entity\TblProductosSeriales'
// 'inherit_data' => true
));
}
/**
* #return string
*/
public function getName()
{
return 'sava_inventariobundle_serial';
}
}
i imported my orm files with the php app/console doctrine:mapping:import command from the tables shown above.
this is my product orm.
sava\InventarioBundle\Entity\TblProductos:
type: entity
table: tbl_productos
fields:
idProduct:
id: true
type: integer
unsigned: false
nullable: false
column: id_product
generator:
strategy: IDENTITY
lifecycleCallbacks: {
}
my serial key table orm.
sava\InventarioBundle\Entity\TblProductosSeriales:
type: entity
table: tbl_productos_seriales
fields:
idProductoSerial:
id: true
type: integer
unsigned: false
nullable: false
column: id_producto_serial
generator:
strategy: IDENTITY
serial:
type: string
length: 80
fixed: false
nullable: false
manyToOne:
idProduct:
targetEntity: TblProductos
cascade: { }
mappedBy: null
inversedBy: null
joinColumns:
id_product:
referencedColumnName: id_product
orphanRemoval: false
idinvoice:
targetEntity: TblPedidos
cascade: { }
mappedBy: null
inversedBy: null
joinColumns:
id_pedido:
referencedColumnName: id_invoice
orphanRemoval: false
lifecycleCallbacks: { }
this is my invoice orm.
sava\InventarioBundle\Entity\TblPedidos:
type: entity
table: tbl_pedidos
fields:
idinvoice:
id: true
type: integer
unsigned: false
nullable: false
column: id_invoice
generator:
strategy: IDENTITY
lifecycleCallbacks: { }

If you don't want the user to be able to choose the relation why are you adding them to the form ? You can set them server side, in the controller :
so :
get the data of your form
query the database with the id from your form to get the two other ones
hydrate the object ( formObject->setStuff($id) )
persist
To give you an idea of what to do : for example if you have a serial and want to get your product id from it
$serial = new Serial;
$form = $this->createForm(new SerialType, $serial);
$request = $this->get('request');
if ($request->getMethod() == 'POST') {
$form->bind($request);
// if form is valid
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
// get the data sent from your form
$data = $form->getData();
$idSerial = $data->getSerial();
// find your ids according to the serial you just got from the form
$repository = $this->getDoctrine()->getManager()->getRepository('AcmeBundleBundle:Products');
$idProduct = $repository->findBySerial($idSerial);
// hydrate the $serial
$serial->setProduct($idProduct);
$em->persist($serial);
$em->flush();
return ....
}
}
if you have the ids in your template do
<form role="form"
action="{{ path('your_route', { 'idProduct': idProduct, 'idInvoice': idInvoice }) }}"
...
</form>
And then you can just get them in your controller like so
UpdateSerialAction($idProduct, $idInvoice)
{
and hydrate the form object with those two arguments
