Introduction

Google reCaptach is an easy to use and free service that protects your site from spam and bot. Users usually just need one click to pass the check instead of reading twisted words like Captcha. This article will show you how to use it within ZK framework.

Get reCaptcha

Please follow Google's guide to get reCaptcha API key: https://developers.google.com/recaptcha/docs/start

How to Apply

Include recaptcha API & Configuration

<zk xmlns:c="client" xmlns:x="xhtml">
	<script type="text/javascript" src='https://www.google.com/recaptcha/api.js' defer="true" />
	...
	<x:div id="recaptcha" class="g-recaptcha" 
		data-sitekey="your-key"
		data-callback="afterValidate" />

If the key is correct, you should see the reCaptcha is rendered. If not, open developer tool / Console tab to check an error.
