Article Update: Creating a Compound Field Module for CCK in Drupal
I just updated my article on Creating a Compound Field Module for CCK in Drupal. It's a programming tutorial on how to create a custom field module for the Drupal content management system and its Content Construction Kit module. In particular, the article covers how to create a custom field that packages an image upload, a caption, and taxonomy term, as one "compound" field.
The article and the accompanying module download have now been updated for compatibility with the released 6.x-3.0 versions of ImageField and FileField. Unfortunately, these modules changed a lot between the Alpha releases and the final releases, so the earlier version of the compound field module was totally incompatible with the released versions. The version in the article now is compatible. (Thanks to Greg Dunlap AKA heyrocker for pointing out the incompatibility.)
I also added more examples for compound fields that don't contain an image.
