I've done this using the CCK Computed Field. But I would like to learn more about CCK fields development. And my company give some time to do this... Thanks. David Brian Vuyk wrote:

Might be a little simpler than doing something in a module. Unless, of course, you don't want it's function accessible from the frontend.

Hi I'm developping a custom CCK field for Drupal 6. I'm don't want the user set the value himself. So, this field has no widget.

I'm looking for how to set the value when the node is saved. (the value is set when the node is created et not updated) In hook_field, I tried to use 'presave' ou 'validate' for $op, but I've some problems to work with it : - 'presave' seems to be called when the node is displayed... - when the node is created, the field has no value ($items[0]['value'] does not exists) - ...

I 've look in some others CCK fields, but no one work like this.

I copied the text_field CCK field, renamed all 'text_field' references, simplified it and removed the widget.

Can someone help me or point me to a good web page ? (not the CCK dev documentation !, I read it many times!)

Thanks.

David

Finaly, I decided to use the computed field. Thanks All ! David Chris Johnson wrote:

I've struggled with doing this, too. I updated some of the CCK developer documentation on drupal.org to Drupal 6 as I went along figuring things out, but obviously only hit minor bits and pieces.

You can look at the source for the moodle module (http://drupal.org/project/moodle) in the moodle.cckfield.inc file for the development code I was last working on to do this a few months ago. It is a very hacked up copy of the computed field code, if I remember correctly.

Please, please! -- if anyone figures out any pieces of how CCK works in Drupal 6 -- add documentation below the top-level page at http://drupal.org/node/101742 .

The only 2 people who know how it really works are the maintainers, and they're busy working on Drupal 7.
