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... http://api.drupal.org/api/drupal/modules!field!field.api.php/function/hook_f... http://api.drupal.org/api/drupal/modules!field!field.attach.inc/group/field_... Let us know how it went. I have considered doing the same. -- /Kindest regards,/ /*Dayton Perkins*/ Dayton Perkins Good News Design Intelligent Web Programming for Business Dayton Perkins: Recent American Expat in Hong Kong dayton@goodnewsdesign.com <mailto:dayton@goodnewsdesign.com> dayton@goodnewsdesign.com <mailto:dayton@goodnewsdesign.com> Phone Me U.S Phone (rings me in HK) 616-795-9039 http://goodnewsdesign.com GND Logo <http://goodnewsdesign.com><http://goodnewsdesign.com>
