Math Field

The Math Field module defines a new field type to dynamically calculate values on entity forms. Math Field is an alternative to Computed Field that does not require the use of PHP Filter.


Download, install, and enable the cTools and Math Field modules.

TFA plugins and plugin development

TFA plugins provide the form and validation handling for 2nd factor
authentication of a user. The TFA module will interrupt a successful username and password authentication and begin the TFA process (see Configuration for exceptions to this statement), passing off the form control and validation to the active plugin.

Mentoring at Drupal events

A guide to good mentoring experiences

At Drupal events, the Mentored Core Sprint usually takes place in a large room with many round tables. You will mentor 3 to 8 people sitting at your table. This guide aims to help both new and experienced mentors have good experiences while mentoring. It is based on notes taken during mentoring orientation with Cathy Theys (YesCT) at DrupalCon Bogotá in 2015.
