Examples

RestFileType for file upload

<?php
    /** @var @UploadedFile $upload */
    $upload = $request->files->get('file');
    
    if (isset($upload)) {
        $form = $this->createFormBuilder()
            ->add('file', RestFileType::class, [
                'allow_delete' => true,
                'validate_extensions' => true,
                'validate_size' => true,
                'private' => false,
            ])
            ->getForm();
    
        $form->handleRequest($request);
        $clearMissing = $request->getMethod() != 'PATCH';
        $form->submit(['file' => $upload], $clearMissing);
    
        $data = $form->getData();
    
        if (isset($data['file'])) {
            /** @var File $file */
            $file = $data['file'];
            $em = $this->getDoctrine()->getManager();
            $em->persist($file);
            $em->flush();
        }
     }

RestFileType submit of existing entity

<?php
    /**
    * $file = ['file' => ['id' => 8]]
    */
    $file = json_decode($request->getContent(), true);
    
    $form = $this->createFormBuilder()
        ->add('file', RestFileType::class, [
            'allow_delete' => true,
            'validate_extensions' => true,
            'validate_size' => true,
            'private' => false,
        ])
        ->getForm();

    $form->handleRequest($request);
    $clearMissing = $request->getMethod() != 'PATCH';
    $form->submit($file , $clearMissing);

RestFileType delete of existing entity

<?php
    /**
    * $file = ['file' => ['id' => 8, 'delete' => true]]
    */
    $file = json_decode($request->getContent(), true);
    
    $form = $this->createFormBuilder()
        ->add('file', RestFileType::class, [
            'allow_delete' => true,
            'validate_extensions' => true,
            'validate_size' => true,
            'private' => false,
        ])
        ->getForm();

    $form->handleRequest($request);
    $clearMissing = $request->getMethod() != 'PATCH';
    $form->submit($file , $clearMissing);
    
    $em = $this->getDoctrine()->getManager();
    $em->flush();

Upload and validate file via service

<?php
    /** @var @UploadedFile $upload */
    $upload = $request->files->get('file');
    
    if (isset($upload)) {
        $validator = $this->container->get('rest_uploader.validator');
        $uploader = $this->container->get('rest_uploader.manager');
        
        if ($validator->isExtensionAllowed($upload) && $validator->isSizeValid($upload)){
            /** @var File $file */
            $file = $uploader->upload($upload, false);
        }
