set data to entity field with query_builder and multiple true - php

Question

I have the following field
->add('specialProduct' , 'entity', array(
'class' => 'BSSmartDistributionBundle:Product',
'expanded' => true,
'multiple' => true,
'required' => true,
'label' => false,
'mapped' => false,
'query_builder' => function(ProductRepository $er) {
return $er->createQueryBuilder('p')
->where('p.active = :active')
->andWhere('p.type = :type')
->setParameter('type', 1)
->setParameter('active', 1);
},
'data' => $this->specialProduct # not working
))
I get the data and store it in session
$specialProduct = $form->get('specialProduct')->getData();
$request->getSession()->set('specialProduct', $specialProduct);
data :
Doctrine\Common\Collections\ArrayCollection Object
(
[elements:Doctrine\Common\Collections\ArrayCollection:private] => Array
(
[0] => BS\SmartDistributionBundle\Entity\Product Object
(
[id:BS\SmartDistributionBundle\Entity\Product:private] => 6
[type:BS\SmartDistributionBundle\Entity\Product:private] => 1
[name:BS\SmartDistributionBundle\Entity\Product:private] => Starter Pack
[duration:BS\SmartDistributionBundle\Entity\Product:private] => 1
[description:BS\SmartDistributionBundle\Entity\Product:private] => Tout de suite
[full_description:BS\SmartDistributionBundle\Entity\Product:private] => blabla
[price:BS\SmartDistributionBundle\Entity\Product:private] => 39
[picture:BS\SmartDistributionBundle\Entity\Product:private] => /tmp/php6h3rXK
[active:BS\SmartDistributionBundle\Entity\Product:private] => 1
)
[1] => BS\SmartDistributionBundle\Entity\Product Object
(
[id:BS\SmartDistributionBundle\Entity\Product:private] => 15
[type:BS\SmartDistributionBundle\Entity\Product:private] => 1
[name:BS\SmartDistributionBundle\Entity\Product:private] => asdsd
[duration:BS\SmartDistributionBundle\Entity\Product:private] => 2
[description:BS\SmartDistributionBundle\Entity\Product:private] => asdasd
[full_description:BS\SmartDistributionBundle\Entity\Product:private] => adsd
[price:BS\SmartDistributionBundle\Entity\Product:private] => 12
[picture:BS\SmartDistributionBundle\Entity\Product:private] => uploads/product/d978b90215d06fbf569203e7cf2d5aef.png
[active:BS\SmartDistributionBundle\Entity\Product:private] => 1
)
)
)
now I'd like to check the corresponding checkboxes !?
Same field with multiple false I can set the value with
'data' => $this->value
I tried
'data' => $this->specialProduct # not working (contains $specialProduct above)
How can I set those values ?
Do I need to pass an array ?
Thanks !

Answer 1

Setting default values for a form is always done on an instance of FormInterface using setData and not as data in options array for each form field. The docs says:
The default values for form fields are taken directly from the underlying data structure (e.g. an entity or an array). The data option overrides this default value.
If you used data option than the form will always have preselected what's in data and not from the entity.
So if I understand your code correctly it'd be:
$form->setData([
specialProduct => $request->getSession()->get('specialProduct')
]);
Because the stored data in session is a collection of Products.

I ended doing it this way :
I was storing and passing to the form an arrayCollection
controller :
$specialProduct = $form->get('specialProduct')->getData();
$request->getSession()->set('specialProduct', $specialProduct);
form :
$this->specialProduct = $options['specialProduct'];
'data' => $this->specialProduct
instead I use an array with only the ids
foreach ($specialProduct as $product) {
$specialProductIds[] = $product->getId();
}
$request->getSession()->set('specialProductIds', $specialProductIds);
pass it to the form with entity manager
$this->specialProductIds = $options['specialProductIds'];
$this->em = $options['em'];
in the form
public function availablespcialProduct($ids) {
if ($this->em) {
return $this->em
->getRepository('BS\SmartDistributionBundle\Entity\Product')
->findById(
$ids
);
}
}
and finally
'data' => $this->availablespcialProduct($this->specialProductIds)
Still waiting for a cleaner solution !
Thanks !
