Not quite, the problem is there are certain form fields (which can vary
depending where the fileuploader is included) that are used to cancel
the file upload process. So when dropzone slurps up all the form field
from it's enveloping form it gets fields like '[whatever]_cancel' that
it doesn't want.

In the php code there are things like if('cancel') are higher up in the
hierarchy of things to do and when a cancel is encountered the normal
response from pieforms is to return the page to replace itself, which is
all HTML.  So not an error, just normal way of things.

However when the point of actually trying to upload a file is reached
the response back is in JSON (either success or fail), which is what
dropzone is expecting, and not the HTML one.

if it gets the HTML response it throws the 'SyntaxError: JSON.parse:
unexpected character' - that tells me that it is receiving a field (like
cancel) that it shouldn't.

These should all be ironed out now. But if the error occurs again the
first thing is to do a console.log() on the form fields that
filedropzone.js is sending and see if any of those are not meant to be
sent on a fileupload submit.
