## 설명

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:
 2.  * 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
 3. Add an **HTML** field containing the placeholder `{math_question}` wherever you
    want the question text to appear.
 4. 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.

This plugin is independently developed and is not affiliated with, endorsed by, 
or sponsored by Rocketgenius, Inc. or Gravity Forms.

## 설치

 1. Upload the `math-captcha-for-gravity-forms` folder to `/wp-content/plugins/`, or
    install directly through the WordPress plugin screen.
 2. Activate the plugin through the ‘Plugins’ screen in WordPress.
 3. Make sure Gravity Forms is installed and active — this plugin does nothing without
    it.
 4. Edit the form(s) you want to protect and add the three fields described above (
    Admin Labels `num1`, `num2`, `math_answer`) plus an HTML field containing `{math_question}`.

## FAQ

### Does this work without Gravity Forms?

No. This plugin only adds functionality on top of Gravity Forms and does nothing
if Gravity Forms is not installed and active. You’ll see an admin notice if it’s
missing.

### Does this send any data to external services?

No. All number generation and validation happens entirely server-side, on your own
site.

### Can I style the question text?

Yes — the question is wrapped in a `<strong>` tag inside your HTML field, so you
can wrap it with your own markup/CSS in the HTML field content.

### What happens if I don’t add the math_answer field?

The plugin checks for all three fields (`num1`, `num2`, `math_answer`) by Admin 
Label. If any are missing from a given form, validation is skipped silently for 
that form, so it won’t break forms that aren’t using the captcha.
