Taxonomy Preferences

Description

The Taxonomy Preferences (taxonomy_preferences) module provides a block for end users to choose their preferences. The module has a configuration page where site administrators can choose which taxonomy terms can be chosed. The end user marks his selection and submit the values. The values are then stored in session using the php super global $_SESSION for future use.

Requirements

This module requires no modules outside of Drupal core. However, it was developed to use combined with Views Extras module since Views Extras has an option to provide a contextual filter to a view based on session variables.

Installation
