UPDATE: APRIL 17 2015
With the advent of the iPerceptions Universal Code, which simplifies the process of implementing multiple projects on your website, please note that our plugins for implementing the iPerceptions code will no longer be supported. To learn more about our Universal Code, please check out this section of our support forum.
You can use the iPerceptions Survey Drupal plugin (available for download here) to easily implement the iPerceptions script on a Drupal-based website. This plugin is available with all versions of the 7.x version series of Drupal.
Simply refer to the installation instructions that are provided within the README.txt file that is downloaded with the plug-in. The iperceptions_survey folder should be placed in the sites/all/modules folder of the Drupal installation.
If you have any questions with regards to this plugin, please feel free to provide your question through a support ticket which you can create here.
