How to get user ID (FOSUserBundle) in form builder in Symfony2? - php

Question

I'm quite new here, be patient, please.
I'm trying to make notice board project in Symfony2 using FOSUserBundle.
I try to get logged user id to put it into form created with form builder (and then to MySQL database).
One of attempts is:
public function createNoticeAction(Request $request)
{
$notice = new Notice();
$form = $this->createFormBuilder($notice)
->add("content", "text")
->add("user_id","entity",
array("class"=>"FOS/UserBundle/FOSUserBundle:", "choice_label"=>"id"))
->add("isActive", "true")
->add("category", "entity",
array("class" => "AppBundle:Category", "choice_label" => "name"))
->add("save", "submit", array("label" => "Save"))
->getForm();
$form->handleRequest($request);
$em = $this->getDoctrine()->getManager();
$em->persist($notice);
$em->flush();
return $this->redirectToRoute('app_user_showuserpage');
}
I tried many solutions again and again and I get some error.

Answer 1

You already have the user object Symfony > 2.1.x
In you Controller like this:
$userId = $this->getUser()->getId();
...
$notice->setUserId($userId);
$em->persist($notice);
Don't ->add field in you FormBuilder, its not safely. Set this value in you Controller and don't ->add this field in FormBuilder

Answer 2

for symfony 3.2.13
have excelent solution (just because is working, but is dangerous if someone discover it in pure HTML)
1) first build YourFormType class.
add normal field in Forms/YourFormType.php (if not, formbuilder tell you that you passing smth not quite right (too many fields) ; -) )
$builder
->add(
'MyModelAddedById',
HiddenType::class,
[
'label' => 'echhh', //somehow it has to be here
'attr' => ['style' => 'display:none'], //somehow it has to be here
]
);
2) in your controller
public function addSomethingAction(Request $request){
$form = $this->createForm(MyModelFormType::class);
//set field value
$request->request->set("prodModelAddedById", $this->getUser()->getId());
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$product = $form->getData();
$em = $this->getDoctrine()->getManager();
$em->persist($product);
$em->flush();
$this->addFlash('success', 'record was added');
return $this->redirectToRoute('products');
}
return $this->render(
'default.add.form.html.twig',
[
'newprod' => $form->createView(),
]
);
}
explenation:
you are passing a field and variable to formbuilder (settig it already to default value!)
and important thing, becose of BUG in my opinion - you can't in your form type set method:
public function getBlockPrefix()
{
//return 'app_bundle_my_form_type';
}
because
$request->request->set
can't work properly if your POST data from form are in bag (parameterbag)
no entity managers, no services, no listeners...
hope it helps.
