I am trying to implement Googles new 'NoCaptcha' on my site. So far I have the widget appearing fine, but it does not verify on my PHP page.
My code is set up as such:
In <head>
<script src='https://www.google.com/recaptcha/api.js'></script>
Client Side:
<form id="contactform" action="bookingverify.php" method="POST">
<input type="text" name="name" size="41">
<!--OTHER FORM INPUTS-->
<div class="g-recaptcha" data-sitekey="mypublickey"></div>
</form>
Server Side (bookingverify.php)
$captcha;
if(isset($_POST['g-recaptcha-response'])){
$captcha=$_POST['g-recaptcha-response'];
}
if(!$captcha){
echo '<h2>Please check the the captcha form.</h2>';
exit;
}
$response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=myprivatekey&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']);
if($response.success==false){
echo '<h2>You are spammer</h2>';
}
else{
//SEND MAIL
}
I've tried echoing $_POST['g-recaptcha-response'] but it appears empty. It's like that variable is not being posted to the php.
Does anyone know what I am doing wrong here?
Your code ran fine on my test server with my own private / public key. It seems trivial, but the only thing I had to add - do you have a submit button in your other form inputs? This is what actually posts the data to your PHP script.
Otherwise, add
var_dump($_POST['g-recaptcha-response']);to your bookingverify.php and see what it outputs.OK I have no idea why but I deleted the
exit;in the 2nd IF statement and it worked. Weird.i had a similar issue. Apparently if you dont click the checkbox the $_POST['g-recaptcha-response'] comes in empty. so just make sure you click it when testing
