I need to have content that is submitted by users of a certain role to be approved by an administrator before it is published. I thought this functionality was build in already, but I just can't seem to find where it is.
From the Workbench project page:
Workbench provides overall improvements for managing content that Drupal does not provide out of the box. Workbench gives us three important solutions:
- a unified and simplified user interface for users who ONLY have to work with content. This decreases training and support time.
- the ability to control who has access to edit any content based on an organization's structure not the web site structure
- a customizable editorial workflow that integrates with the access control feature described above or works independently on its own
From the Workbench Moderation project page:
Workbench Moderation adds arbitrary moderation states to Drupal core's "unpublished" and "published" node states, and affects the behavior of node revisions when nodes are published. Moderation states are tracked per-revision; rather than moderating nodes, Workbench Moderation moderates revisions.
You could use the Rules module to setup a workflow.
