I have all my code set up exactly how Google documents the API but it keeps returning a boolean of false, is there something wrong that I have done?
<?php
if(isset($_POST['sendEmail'])) {
$privateKey = "__my_secret_key__";
$response = $_POST['g-recaptcha-response'];
$remoteip = $_SERVER['REMOTE_ADDR'];
$url = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=$privateKey&response=$response&remoteip=$remoteip");
$result = json_decode($url, true);
if($result->success == true) {
$name = strip_tags(trim($_POST['name_1']));
$surname = strip_tags(trim($_POST['surname_1']));
$userArray = [
'name' => $name,
'surname' => $surname,
];
var_dump($userArray);
} else {
echo "reCaptcha failed, please try again...";
}
}
?>
and my HTML form with the JavaScript link copied from Google and the data-sitekey I received:
<html lang="en">
<head>
<meta charset="utf-8">
<title>Recaptcha Example</title>
</head>
<body>
<br>
<br>
<form action="" method="post">
<div class="form-row">
<input name="name_1" placeholder="Your name" type="text">
</div>
<br>
<div class="form-row">
<input name="surname_1" placeholder="Your surname" type="text">
</div>
<br>
<div class="form-row">
<div class="g-recaptcha" data-sitekey="__Site_key__"></div>
</div>
<br>
<input name="sendEmail" type="submit" value="Call me back">
<br>
<h4 id="response"></h4>
</form>
<script src='https://www.google.com/recaptcha/api.js'></script>

Register reCAPTCHA v3 keys You need to first register your website and get the keys here – https://www.google.com/recaptcha/admin/create. Add a label, select reCAPTCHA v3, type your domain name(s) and submit. This will generate a “site key” and a “secret key”. Copy both and keep them safe.
Add this script:
<script src='https://www.google.com/recaptcha/api.js'></script>
<script>
function get_action(form)
{
var v = grecaptcha.getResponse();
if(v.length == 0)
{
document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
return false;
}
else
{
document.getElementById('captcha').innerHTML="Captcha completed";
return true;
}
}
</script>
and add this HTML before your submit button:
<div class="g-recaptcha" id="rcaptcha" data-sitekey="site key"></div>
<span id="captcha" style="color:red" /></span> <!-- this will show captcha errors -->
