Views Access Conditions

A Drupal module that allows you to control access to views based on configurable conditions.

Overview

Views Access Conditions provides a flexible way to control when views are accessible on your Drupal site. This module extends Drupal's views access plugin system to include conditional rules, making it easy to control access to views based on various conditions.

In version 2.1+ users can also control what fields and filters are visible in their views based on conditions. Contextual filters can be enabled/disabled based on conditions as well.

But why?

The benefit of this approach is for multi-sites, or shared codebase platforms, that share configuration across multiple sites but want some flexibility in control of when views are accessible. For example, if there are two sites sharing the same codebase, Site A and Site B, and only Site B needs a particular view to be accessible then using views access plugins, we are able to configure access based on a condition - this could be one provided by core, the contrib space, or something custom. This way both sites can still share the same configuration, as the access conditions are stored in config, but the conditions are evaluated per-site.
