In formidable forms there is a very useful feature of "conditional logic", in which you can hide or show a filed based upon the value of another field.
Is it possible to do such a thing with a file upload?
For example, field 1 is shown when a file is uploaded in the file upload field.
(in general, if there is a way, even through php code, to see if a certain file upload field has a file uploaded)

Hi, yes, that would be very good. Conditional logic in forms for upload field seems not to work out of the box.

Because file upload fields work with AJAX, the best approach would be to use jQuery to display the conditional field. On the form, customize the field's HTML to hide the field with CSS. Then create your jQuery snippet to monitor the AJAX.complete() event. When you determine that the file upload field AJAX executes, you can read the results and set the field to display with jQuery.show().
