Re: [development] Creating fields: custom vs. CCK

First off I think you are comparing CCK to a custom module (.module). I would start by looking at CCK and see if it will meet your needs. If it falls short there are some alternatives to implementing a complete custom content type with a module. If you just need additional validation you can write a module that implement hook_nodeapi and adds validation to a content type created with CCK. Another approach I have used where I need more than custom validation is to use a module to provide the skeleton for a new content type (title, body plus and "special" fields I care about) and include any special logic I might need and then use CCK to add additional fields as needed.
