Form Validation Class

[eluser]xwero[/eluser]
The validation class handles strings, I think that is why the people at Ellislab seperated the two. If you mix the two, the validation class also has to take care of the upload itself.

I wondering how much of the file upload class you are going to use in the validation class? And how are you going to work out if people want to rename the file, resize it, ... ?

It would be nice to have one validation class for everything so i'm looking forward to your results.
