<form action="" method="post">
<input type="text" name="text4" id="text4" style="width:400px" /><br/><br/>' . '<script type="text/javascript"
src="http://www.google.com/recaptcha/api/challenge?k=XXXXXXXXXXXXXXXXXX">
</script>
<noscript>
<iframe src="http://www.google.com/recaptcha/api/noscript?k=XXXXXXXXXXXXXXXXXX"
height="300" width="500" frameborder="0"></iframe><br>
<textarea name="recaptcha_challenge_field" rows="3" cols="40">
</textarea>
<input type="hidden" name="recaptcha_response_field"

require_once('recaptchalib.php'); $privatekey = "your_private_key"; $resp = recaptcha_check_answer( $privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"] ); if (!$resp->is_valid) { // What happens when the CAPTCHA was entered incorrectly die( "The reCAPTCHA wasn't entered correctly. Go back and try it again." . "(reCAPTCHA said: " . $resp->error . ")" ); } else { // Your code here to handle a successful verification }
