The file field in my form is not mandatory, therefore $this->upload->do_upload() would not work because an empty file field is okay in this situation and $this->upload->do_upload() would return false, as if something went wrong. In this case, false is needed IFF:

upload fails AND there is an actual file attempting to be uploaded,
