### Can you set form values at the validation() step?

Re: Can you set form values at the validation() step?

To get data out of the validation process, don't try to save it into a hidden form field. Just save it as $this->computeraspectratio (or something), and add a$this->get_computed_aspect_ratio method (or something similar). (Or, you could override get_data() to include the extra computed values.)

You're right that worked. I ended up using data_postprocessing() which works just like get_data().
