这是服务器端处理表单提交的send.php代码:
<?php

'response' => $user_response
);
foreach($fields as $key=>$value)
$fields_string .= $key . '=' . $value . '&';
$fields_string = rtrim($fields_string, '&');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/recaptcha/api/siteverify');
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);
$result = curl_exec($ch);
curl_close($ch);
return json_decode($result, true);
}
// Call the function post_captcha
$res = post_captcha($_POST['g-recaptcha-response']);
if (!$res['success']) {
// What happens when the CAPTCHA wasn't checked
echo '<p>Please go back and make sure you check the security CAPTCHA box.</p><br>';
} else {
// If CAPTCHA is successfully completed...
$to = "hello@videoproductionedinburgh.co.uk";
$name = $_POST['name'];
$subject = $_POST['subject'];
$body = stripslashes($_POST['message']);
