File uploading: Optional fields?

Big apologies on the late reply. Finally managed to grab a spare minute to try out your example LuckyFella73, and it worked a treat! Huge thanks!

I had something similar before hand, but my if statement wrapped around the $this->upload->do_upload() statement. With the addition of a foreach loop and your example, it came out perfect.

Thanks again!
