Symfony 3.4 file is not validated when using createFormBuilder

Here is what I have tried:

  $form = $this->createFormBuilder(null, ['method' => 'POST', 'csrf_protection' => false])
            ->add('file', FileType::class, [
                'required' => true,
                'constraints' => [
                    new File([
                        'mimeTypes' => [
                            'application/pdf',
                            'application/msword',
                            'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
                            'application/vnd.ms-excel',
                            'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
                            'image/gif',
                            'image/png',
                            'image/jpeg',
                            'application/vnd.oasis.opendocument.text',
                            'application/vnd.oasis.opendocument.spreadsheet'
                        ]
                    ]),
                    new Count(['min' => 1, 'max' => 1])
                ]
            ])
            //->add('submit', SubmitType::class)
            ->getForm();





        $form->handleRequest($request);
//        $form->submit($request->request->all(), false);
        $form->submit($request->files->get($form->getName()));

//        $this->


//        if ($form->isValid()) {
        if (/*$form->isSubmitted() &&*/ $form->isValid()) {

Handle request does not submit form. If I call submit after handle request, it still does not validate.

I even tried

 /** @var UploadedFile $f */
            $f = $request->files->get('file');



            $violations = $this->container->get('validator')->validate($f, [
                new File([
                    'mimeTypes' => [
                        'application/pdf',
                        'application/msword',
                        'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
                        'application/vnd.ms-excel',
                        'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
                        'image/gif',
                        'image/png',
                        'image/jpeg',
                        'application/vnd.oasis.opendocument.text',
                        'application/vnd.oasis.opendocument.spreadsheet'
                    ]
                ]),
                new Count(['min' => 1, 'max' => 1])
            ]);

But validate gives error:

Expected argument of type "array or \Countable", "Symfony\Component\HttpFoundation\File\UploadedFile" given.

I see this is not as in documentation example, but I want to not refactor much if possible. This should be simple fix but I spent few hours and cannot find.

Can you show the exception stack trace (i.e. where exactly is the exception being thrown)? - xabbuh
@xabbuh - updated question - Darius.V
Now I see that the error comes from new Count(). When I remove count, then it is fine. But how do I validate that it is one file? - Darius.V

$violations = $this->container->get('validator')->validate($f, [
                new File([
                    'mimeTypes' => [
                        'application/pdf',
                        'application/msword',
                        'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
                        'application/vnd.ms-excel',
                        'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
                        'image/gif',
                        'image/png',
                        'image/jpeg',
                        'application/vnd.oasis.opendocument.text',
                        'application/vnd.oasis.opendocument.spreadsheet'
                    ]
                ]),
                //new Count(['min' => 1, 'max' => 1])
            ]);

The problem was new Count. It is not needed because for validate method if we upload multiple files, then $f will be array and there will be exception, so user will not be able to upload multiple files.
