Content Construction Kit (CCK)

The Content Construction Kit allows you to add custom fields to nodes using a web browser.

Drupal 7 and Fields in Core

Most of CCK has moved to core in the Drupal 7 version. The D7 version of the contrib CCK package currently contains:

• D6 -> D7 data migration code, see Updating Fields and Data from D6 to D7 for more information on the status of that code.
• some miscellaneous helpers to do things that core will not do, like maintain the PHP code snippets some fields may have been using to define allowed values (partially working)

The following features are now handled by separate, dedicated projects:

• nodereference and userreference : References project - co-maintainer needed
• content_permissions: Field permissions module. See this issue for progress on the D7 version.
• fieldgroup : Field group module - with much more awesomeness than in D6 !

Yet to be defined, nothing ported yet:

• content_copy : The D7 branch of the Features module supports expoting and importing content types and fields in 'feature' modules. There is currently no UI to manually export and import field definitions.

Integration with other modules:

• Views - all Views field integration is handled by Views in D7.
• Panels - all Panels field integration is handled by Panels in D7.
• Token - see the D7 version of the Token module.
• Devel - the Devel module will handle field generation code in D7.

Everything else is in Drupal 7 core.

CCK Resources

CCK is a very powerful system with many different contributed modules to extend its functionality. Install the Advanced Help module for additional help, and use the Views module to display CCK information in a variety of ways.
