Plugin Description

Math Captcha for Gravity Forms adds a basic “what is X + Y” challenge to any Gravity Forms form, helping block automated spam submissions without relying on third-party CAPTCHA services, external API calls, or client-side JavaScript.

How it works

1. Add three fields to your Gravity Forms form:
   • A Number (or Hidden) field with Admin Label num1
   • A Number (or Hidden) field with Admin Label num2
   • A Number field with Admin Label math_answer, where the visitor types their answer
2. Add an HTML field containing the placeholder {math_question} wherever you want the question text to appear.
3. The plugin fills num1 and num2 with random numbers on each page load, replaces {math_question} with the rendered question, and validates math_answer server-side on submit.

The same numbers persist across a failed-validation reload, so the question a visitor sees always matches what’s being validated.

Why server-side?

No JavaScript means no scripts to block, no client-side bypass, and no impact on page-load performance.
