Get reCAPTCHA API keys:

For adding reCAPTCHA to your site, you need to register your site and get reCAPTCHA API keys. Register your site at Google from here – https://www.google.com/recaptcha/admin

– Get your Site Key. Site key is used to display the reCAPTCHA widget. The code is in the pattern of the image below

– Get your Secret Key. Secret key helps authorizes communication between your site and the reCAPTCHA server. The code is in the pattern of the image below

 

For Advanced Contact Form:

– In contact-us-advanced.php: Remove and add HTML like the images below:

CHANGE:

TO:

<div class="col-md-12">
	<div class="row mb-sm">
		<div class="col-md-12">
			<div class="g-recaptcha" data-sitekey="YOUR_SITE_KEY"></div>
		</div>
	</div>
</div>

– Add this script like image below:

<script src='https://www.google.com/recaptcha/api.js' async defer></script>

– In top of contact-us-advanced.php change ALL PHP code to this below:
IMPORTANT: Change “YOUR_SECRET_KEY” with your generated Google reCAPTCHA Secret Key.
