Symfony 2.8 - Set default value with data from session and propel - forms

Question

I use Propel in a project & I try to set default value my form which uses a ModelType input and I need to set a default value stored in session in this form and where this session is not null for the stored value used in this functionnality.
This is my form :
/**
* #param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Fcl\VitrinellisBundle\Model\ProfileVariety',
'name' => 'profile_variety_search',
'locales' => ['fr'],
'session' => null
));
}
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name', ModelType::class, array(
'class' => 'Fcl\VitrinellisBundle\Model\ProfileVariety',
'query' => ProfileVarietyQuery::create()->orderById(),
'property' => 'name',
'label' => 'Profil recherché',
'expanded' => false,
'multiple' => false,
'required' => false,
'placeholder' => '- Filtrer par profil -',
'attr' => array(
'onchange' => 'submit()',
'class' => 'col s3'
)
))
;
}
This is my treatment :
public function listAction(Request $request = null)
{
$pModelManager = $this->get('fcl_vitrinellis.p_model_manager');
$profileVarietyManager = $this->get('fcl_vitrinellis.profile_variety_manager');
$session = $request->getSession();
$profileVariety = new ProfileVariety();
$models = null;
$form = $this->createForm(ProfileVarietySearchType::class, $profileVariety);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
if (null != $form['name']->getData()) {
$models = $pModelManager->getWebsiteByModel($form['name']->getData()->getName());
$session->set('profileVarietySearch', $form['name']->getData()->getName());
} else {
$models = $pModelManager->getList();
}
} else {
if ($session->has('profileVarietySearch') && null != $session->get('profileVarietySearch')) {
$models = $pModelManager->getWebsiteByModel($session->get('profileVarietySearch'));
} else {
$models = $pModelManager->getList();
}
}
return $this->render('console\p_model_list.html.twig', array(
'objArray' => $models,
'form' => $form->createView()
));
}
I have try to set default data with 'data' option and with PRE_SET_DATA event in the form but I had satisfactory result.

Answer 1

In an EntityType the incoming default 'data' must be an object of the right type. I would first try to see if we have incoming form data.
public function buildForm(FormBuilderInterface $builder, array $options)
{
// Check form data
$formDataEntity = $builder->getData();
// Check if it has the field filled in
if ($formDataEntity && $formDataEntity->getName()) {
$objToSet = $formDataEntity->getName();
} else {
$objToSet = $options['incomingDefaultObject'];
)
$builder
->add('name', ModelType::class, array(
class => 'Fcl\VitrinellisBundle\Model\ProfileVariety',
data => $objToSet,
...
And then for the resolver
/**
* #param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'incomingDefaultObject' => null,
));
}
And you call the form with the default opion in the controller
$form = $this->createForm(YourType::class, $yourObject, array('incomingDefaultObject' => $nameObject));
Warning: if a user decides to leave the field empty this code will always set the default.

Answer 2

I have an other solution.
Create new Model which his name is ProfileVarietySearch, like this :
class ProfileVarietySearch
{
/** #var null|ProfileVariety $profileVariety */
private $profileVariety;
/**
* #return bool
*/
public function is_empty()
{
return is_null($this->profileVariety);
}
/**
* #return null|ProfileVariety
*/
public function getProfileVariety()
{
return $this->profileVariety;
}
/**
* #param $profileVariety
*
* #return ProfileVarietySearch
*/
public function setProfileVariety($profileVariety): self
{
$this->profileVariety = $profileVariety;
return $this;
}
}
In the controller, write this :
public function listAction(Request $request = null)
{
$pModelManager = $this->get('fcl_vitrinellis.p_model_manager');
$profileVarietyManager = $this->get('fcl_vitrinellis.profile_variety_manager');
$session = $request->getSession();
$profileVarietySearch = new ProfileVarietySearch();
$models = null;
if ($session->has('profileVarietySearch') && null != $session->get('profileVarietySearch')) {
$profileVarietySearch->setProfileVariety(
$profileVarietyManager->getByName($session->get('profileVarietySearch'))->getData()[0]
);
}
$form = $this->createForm(ProfileVarietySearchType::class, $profileVarietySearch);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
if (null != $form->getData()->getProfileVariety()) {
$models = $pModelManager->getWebsiteByModel($form->getData()->getProfileVariety()->getName());
$session->set('profileVarietySearch', $form->getData()->getProfileVariety()->getName());
} else {
$session->set('profileVarietySearch', null);
$models = $pModelManager->getList();
}
} else {
if ($session->has('profileVarietySearch') && null != $session->get('profileVarietySearch')) {
$models = $pModelManager->getWebsiteByModel($session->get('profileVarietySearch'));
} else {
$models = $pModelManager->getList();
}
}
return $this->render($this->view_list, array(
'objArray' => $models,
'form' => $form->createView()
));
}
In the ProfileVarietySearchType, write this :
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Fcl\VitrinellisBundle\Form\Model\ProfileVarietySearch',
'name' => 'profile_variety_search'
));
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('profileVariety', ModelType::class, array(
'class' => 'Fcl\VitrinellisBundle\Model\ProfileVariety',
'query' => ProfileVarietyQuery::create()->orderById(),
'property' => 'name',
'label' => 'Profil recherché',
'expanded' => false,
'multiple' => false,
'required' => false,
'placeholder' => '- Filtrer par profil -',
'attr' => array(
'onchange' => 'submit()',
'class' => 'col s3'
)
));
}
