# Zero Captcha

**The simplest way to add a zero friction captcha in your Rails forms.**

A zero captcha works off the idea that most simple bots do not run a full
JavaScript interpreter when crawling web forms, so they are unable to fill a 
required field whereas the required field is actually hidden and autopopulated
by JavaScript in a real browser with a real human. This means having a layer of
spam protection while maintaining zero friction.

This should not be used solely by itself, but can be useful as an extra layer
of defense alongside honeypot captchas and/or more traditional captchas.

## Requirements

Requires jQuery on running on the client side.

## Installation

In your Gemfile, simply add

    gem 'zero-captcha'

## Usage

### form_for

Simply specify that the form has a honeypot in the HTML options hash:

    <% form_for Comment.new, :html => { :zero_captcha => true } do |form| -%>
      ...
    <% end -%>

### form_tag with block

Simply specify that the form has a honeypot in the options hash:

    <% form_tag comments_path, :zero_captcha => true do -%>
      ...
    <% end -%>

### form_tag without block

Simply specify that the form has a honeypot in the options hash:

    <%= form_tag comments_path, :zero_captcha => true -%>
      ...
    </form>
