I need to change the default Drupal functionality of file field:

  • I want to be able to allow upload of all files types, EXCEPT the extensions listed (reversing the current funcitonality)

  • I also want to be able to add a teaser field and a description field to the file.

Any ideas?

  • You might want to think about re-phrasing/re-writing this. I can't make much sense out of it.

The second part of your question is easy with the File Entity module - it turns file uploads into fieldable entities, so adding your teaser/description field is just like adding a field anywhere else in Drupal (make you sure you read the README file - it's not overly clear at first). The module is also on an unstable release, but Dave Reid is pretty damn awesome so I can't imagine it'll be that way for long :-)

Off the top of my head, I can't think of an answer to the first part though I'm afraid.


There's an issue here that has a couple of patches for Core that give you a radio box to either Allow only these file types or Allow everything EXCEPT these file types. I've not tested the patches as I don't really want to patch Core for something that I personally don't need, but definitely give it a read!
