Validation file input and text input

Yes I use callbacks that way and it works. It's like CroNiX posted.
If you set a callback function when setting rules for form validation
the validation is just listening for a TRUE or FALSE returned by your
callback function. In your callback funtion itself you can have all
kind of php code including $_FILE operations. Only the "normal"
validation rules are meant to validate $_POST data.

You said there are no error messages - how do you display them?
Can you post your view file?
