如果我要问的问题看起来很愚蠢，请原谅我。我是一个php新手，所以我正在努力学习。
我受到教程的启发，创建了一个运行良好的 php 联系表单。
但我想添加验证码。所以我试着这样做。
if ($_SERVER["REQUEST_METHOD"] === 'POST' && isset($_POST['recaptcha_response']))) {
// Get the form fields and remove whitespace.
$name = strip_tags(trim($_POST["name"]));
$name = str_replace(array("r","n"),array(" "," "),$name);
$email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
$message = trim($_POST["message"]);
// Check that data was sent to the mailer.
if ( empty($name) OR empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) {
// Set a 400 (bad request) response code and exit.
http_response_code(400);
echo "Oops! There was a problem with your submission. Please complete the form and try again.";
exit;
}
/*------------------- reCaptcha added -----------------------*/
// Build POST request:
$recaptcha_url = 'https://www.google.com/recaptcha/api/siteverify';
$recaptcha_secret = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
$recaptcha_response = $_POST['recaptcha_response'];
// Make and decode POST request:
$recaptcha = file_get_contents($recaptcha_url . '?secret=' . $recaptcha_secret . '&response=' . $recaptcha_response);
$recaptcha = json_decode($recaptcha);
// Take action based on the score returned:
if ($recaptcha->score >= 0.7) {
// Verified - send email
} else {
// Not verified - show form error
}
/*---------------- End reCaptacha --------------------*/
// Set the recipient email address.
// FIXME: Update this to your desired email address.
$recipient = "hello@example.com";
// Set the email subject.
$subject = "New contact from $name";
// Build the email content.
$email_content = "Name: $namen";
$email_content .= "Email: $emailnn";
$email_content .= "Message:n$messagen";
// Build the email headers.
$email_headers = "From: $name <$email>";
// Send the email.
if (mail($recipient, $subject, $email_content, $email_headers)) {
// Set a 200 (okay) response code.
http_response_code(200);
echo "Thank You! Your message has been sent.";
} else {
// Set a 500 (internal server error) response code.
http_response_code(500);
echo "Oops! Something went wrong and we couldn't send your message.";
}
} else {
// Not a POST request, set a 403 (forbidden) response code.
http_response_code(403);
echo "There was a problem with your submission, please try again.";
}
但它返回下面的错误。
stdClass 对象 ( [成功] => [错误代码] =>数组 ( [0] => 缺少输入响应 ( (但
电子邮件仍在发送。因此，该错误对表单没有影响。 你能告诉我问题出在哪里吗？你真的会帮助我的。
提前谢谢你。
