Symfony 5 : handling multiple forms in one controller - symfony

Question

I am trying to manage multiple forms in the same page in Symfony 5 with the following function, but it seems that every time I try to submit a form, only the first form of the list is handled even if it is not the one that has been submitted:
class ContentController extends AbstractController
{
/**
* #Route("/category/edition/{content}", name="edit_category")
*/
public function edition(Request $request, Category $content): Response
{
$forms = [
"edit_category" => $this->createForm(EditCategoryType::class, $content),
"create_post" => $this->createForm(CreatePostType::class)
];
foreach($forms as $form) {
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
// Always prints edit_category
// even when that is the the create_post that is submitted
return var_dump($form->getName());
}
}
return $this->render(
'content/edition.html.twig',
[
'forms' => \array_map(
function($form) {
return $form->createView();
},
$forms
),
'content' => $content,
]
);
}
}
I have seen in other posts that the name of the forms can sometime raise an issue, but I have checked that the forms do have different names, and I have also tried to call handleRequest() on every form in a separate foreach loop because I have seen this done in some posts, but it (quite expectedly I must say) didn't change the behavior.
And I didn't seem to find any unanimous best practice tips about how to handle multiple forms in the same Controller in Symfony, so I was wondering what is the best way to do it, or if it would be cleaner to define a separate action route for each form in order to avoid this problem altogether.
If needed, the content/edition.html.twig file looks something like that:
{% set edit_category_form = forms['edit_category'] %}
{% set create_post_form = forms['create_post'] %}
{{ form_start(edit_category_form) }}
{{ form_errors(edit_category_form) }}
{{ form_end(edit_category_form) }}
{{ form_start(create_post_form) }}
{{ form_errors(create_post_form) }}
{{ form_end(create_post_form) }}
(Category is a classical Symfony entity, EditCategoryType is a form associated with the Category entity and CreatePostType is a form associated with another Symfony entity)

After some research, it seems for some reason like it works if (and only if?) the form is build just before handling the request:
class ContentController extends AbstractController
{
/**
* #Route("/category/edition/{content}", name="edit_category")
*/
public function edition(Request $request, Category $content): Response
{
$self = $this;
$formBuilders = [
"edit_category" => function() use ($self, $content) {
return $self->createForm(EditCategoryType::class, $content);
},
"create_post" => function() use ($self, $content) {
return $self->createForm(CreatePostType::class);
},
];
$forms = [];
foreach($formBuilders as $key => $formBuilder) {
$form = $formBuilder();
$forms[$key] = $form;
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
// Does print the name of the right form
return var_dump($form->getName());
}
}
return $this->render(
'content/edition.html.twig',
[
'forms' => \array_map(
function($form) {
return $form->createView();
},
$forms
),
'content' => $content,
]
);
}
}
It works but it doesn't feel like a proper way to handle this !
