我遇到的问题是，无论是否检查了reCaptcha，表单都已成功提交（我删除了此帖子的密钥）
我想改变的另一件事是当用户在文本字段中输入无效响应时，错误消息显示在同一页面上。 ReCaptcha现在对我来说是更重要的一块。感谢您提供的任何帮助！
<?php
function post_captcha($user_response) {
$fields_string = '';
$fields = array(
'secret' => 'secret key',
'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...
// Paste mail function or whatever else you want to happen here!
echo '<br><p>CAPTCHA was completed successfully!</p><br>';
}
?>
这是提交表单php
