Image uploading

Presenter, _(*6)

/**
 * @var \Pagewiser\Idn\Nette\Api $idnApi
 * @inject
 */
public $idnApi

public function formSuccess(Form $form)
{
    $values = $form->getValues();
    try
    {
        $uploadedFile = $this->idnApi->upload('photos/'.$values['id'].'.jpg', $values['file']->getTemporaryFile());

        if ($uploadedFile['status'] !== 'success')
        {
            // Rollback
        }

        // Commit
    }
    catch (\Api\Exception\ApiException $e)
    {
        $form->addError($e->getMessage());
    }

If you reupload image with the same name, IDN server will clear the cache for this image automatically. It's still good practice to use generated filename, because it will handle local cache in browsers., _(*7)
