How to deserialize an array that comes from a Symfony 4 form?

Question

symfony

There is a form class, I send it with Ajax and the data array looks like this
name_form[fields]: value
I want to deserialize it all into an object

if ($request->isXmlHttpRequest()) {
            $objectNormalizer = new ObjectNormalizer();
            $normalizers = [$objectNormalizer];
            $encoders = [new JsonEncoder()];
            $serializer = new Serializer($normalizers, $encoders);
            $data = $request->getContent();
            $result = $serializer->deserialize($data, SiteCreateDto::class, 'json');
            var_dump($result); exit;
        }

But the object is naturally not filled.
How to decide? Or what to read?
PS It is also necessary to ignore some fields from the form

I don’t understand why you create a serializer so strangely?
Firstly, ObjectNormalizerit has a few more dependencies for its full-fledged work
. Secondly, it’s more correct to get it through DI.

public function submitAction(SerializerInterface $serializer, Request $request)
{
    if ($request->isXmlHttpRequest()) {
        $data = $request->getContent();
        $result = $serializer->deserialize($data, SiteCreateDto::class, 'json');
        var_dump($result); exit;
    }
}

If it didn’t help out of the box ObjectNormalizer, then you will need to write your own: https://symfony.com/doc/current/serializer/custom_...
