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.

First look turns up this: Chris: though I have not done an
implementation, seems likely...<br>

Let us know how it went. I have considered doing the same.<br>
