Simple PHP contact form with Google reCaptcha

So, *everyone* needs a simple form to send emails, via PHP, but we also need a protection agains bots/spammers.
This is code that i’v grabbed from codeforgeek and improved since the original had a few errors that made it impossible to run/work/send email.

It uses Google reCaptcha and you need to register you site/domain on it and grab the site key and the secret key.

The form already has twitter bootstrap classes… but you can remove them! 🙂

The form.php – at the begin
	$to      = [email protected]';
	$subject = 'Support Message';

	// keys from Google reCaptcha
	$sitekey = 'recaptcha_site_key';
	$secretkey = 'recaptcha_secret_key';

	$alert = '';

        		$alert = '<div class="alert alert-warning" role="alert">Please wait until the captcha protection give you a check mark.</div>';


			/* lets set the error message for the alert... */
			if ($alert=='')
				$alert = '<div class="alert alert-danger" role="alert">Some how you have been detected has a spammer.</div>';
			/* the email to you */
			$headers = 'From: '.$to.'' . "\r\n" .
                	'Reply-To: '.$email.'' . "\r\n" .
                	'X-Mailer: PHP/' . phpversion();
            		mail($to, $subject, $message, $headers);
			/* the copy of the email to the *client* */
			$headers = 'From: '.$email.'' . "\r\n" .
				'Reply-To: '.$to.'' . "\r\n" .
				'X-Mailer: PHP/' . phpversion();
			mail($email, 'COPY - '. $subject, $message, $headers);
			/* lets set the success message for the alert... */
			$alert = '<div class="alert alert-success" role="alert">Your email has been sent.</div>';
The html form
<form id="comment_form" action="" method="post">
	<input name="email" type="email" placeholder="Type your email" size="40" class="form-control" value="<?=@$email?>" ><br><br>
	<textarea name="message" rows="8" cols="39" class="form-control"  placeholder="Your message to us..." ><?=@$message?></textarea><br>
	<div class="g-recaptcha" data-sitekey="<?=$sitekey?>"></div><br>
	<input type="submit" name="submit" value="Send message" class="btn btn-default"><br>

Some where at the bottom/footer…

<script src=''></script>


Hope it helps anyone! 🙂
