Chris,

You’ll need something custom, at leeast that’s
how I solved it

I added an extra file field so people could
upload the file, using hook_node_insert/hook_node_update I
intercepted the upload, converted it, and store the result
in the other file field.

You could do it using a custom file field
widget as well, just extend the current one (have a look at
the image field widget, it extends the file widget)

Cheers,

Peter

Subject: [development] File upload and convert

Hi
Folks,

I
have a content type with TWO file fields, in which I
will designate TWO PDFs. On upload completion I want to
run something like: "exec(pdftk f1.pdf background f2.pdf
output f1.pdf)". This will "brand" f1.pdf.

I
don't see any standard mechanism and so I'm not sure
how to go about this. I have a general understanding,
but that doesn't answer the question. I am sure I
don't want to intercept all possible uploads; just the
uploads from this specific content type. So, can I
define a file upload hook which is scoped to this
specific content type? I haven't seen anything that
makes me believe I can. Can I create a custom file
field to use any time I need to perform a conversion?
Can my custom file field "extend" the existing file
field, so I don't have to port improvements/bugfixes
to my custom file field version?

So
many questions... (-:

Thanks
for the help,

Chris.
