Node privacy by role: node view and edit permissions

The node privacy by role module allows users, when creating or editing a post, to select which roles of users on a site will have view, edit, or delete permissions for the node. Community leaders frequently want to give permissions to roles to create and manage content for a site. The ability to publish information, that would traditionally be hoarded, allows communities to educate each other while still preserving the value of knowledge.

Archive: view content by date

NOTE: This module has been removed from core as of 5.0

How to access Help in Drupal 7

Share tables across instances (not recommended)

You can share tables between Drupal installations by setting table prefixes ($db_prefix) on only some tables but not others. One interesting application for this is to share the taxonomy tables (vocabularies, term_data). Another interesting use is to share users across Drupal installations. To share tables in Drupal, sites must be shared in the same database .


This procedure could result in unexpected results, depending on which tables you choose to share, including broken version updates and/or security holes.

Upgrades to the next version of Drupal are not supported! Be sure you have read EVERYTHING on this page, most especially the issues surrounding a major Drupal upgrade, before considering using shared tables!.

Configure error reporting

Where Drupal, PHP and SQL errors are logged. On a production server it is recommended that errors are only written to the error log. On a test server it can be helpful to write logs to the screen. By default, errors are displayed to the screen. You should change this to 'Write errors only to log' only for your production site.

You can tell Drupal to automatically discard error log entries older than the age you specify. This requires a crontab ( to be set up. See step 6 of the install.txt for example of setup.
