Question

我正在尝试使用 PHP 创建联系表单。

我遇到了这些错误。

error

当我仅将此添加到我的网站之一时会发生这种情况它在只有联系表格的静态网页上工作正常。

HTML形式：

            <div class="form-floating mb-4">
              <input type="text" class="form-control" placeholder="Name" id="companyName" required>

            </div>

            <div class="form-floating mb-4">

            <input class="btn btn-primary rounded-pill btn-login w-100 mb-2" type="submit" name="submit" value="Send"/>
          </form>

PHP 文件：

       <?php

use PHPMailer\PHPMailer\PHPMailer;

$errors = [];
$errorMessage = '';

if (!empty($_POST)) {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];

    if (empty($name)) {
        $errors[] = 'Name is empty';
    }

    if (empty($email)) {
        $errors[] = 'Email is empty';
    } else if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        $errors[] = 'Email is invalid';
    }

    if (empty($message)) {
        $errors[] = 'Message is empty';
    }


    if (!empty($errors)) {
        $allErrors = join('<br/>', $errors);
        $errorMessage = "<p style='color: red;'>{$allErrors}</p>";
    } else {
        $mail = new PHPMailer();

        // specify SMTP credentials
        $mail->isSMTP();
        $mail->Host = 'cpl16.main-hosting.eu';
        $mail->SMTPAuth = true;
        $mail->Username = 'info@siyum.me';
        $mail->Password = '27f211b3fcad87';
        $mail->SMTPSecure = 'tls';
        $mail->Port = 2525;

        $mail->setFrom("me@siyum.me", 'Mailtrap Website');
        $mail->addAddress('nethsarasiyum2@gmail.com', 'Me');
        $mail->Subject = 'New message from your website';

        // Enable HTML if needed
        $mail->isHTML(true);

        $bodyParagraphs = ["Name: {$name}", "Email: {$email}", "Message:", nl2br($message)];
        $body = join('<br />', $bodyParagraphs);
        $mail->Body = $body;

        echo $body;
        if($mail->send()){

            header('Location: thank-you.html'); // redirect to 'thank you' page
        } else {
            $errorMessage = 'Oops, something went wrong. Mailer Error: ' . $mail->ErrorInfo;
        }
    }
}

?>

我是PHP的新手，我试图在网上找到一些解决方案，但没有成功。

感谢您的帮助。谢谢

Answer 1

浏览器使用 <input> 元素的 name 属性将数据传回服务器上的脚本。

<input type="text" class="form-control" placeholder="Name" id="companyName" required>

所以你需要添加name属性

<input name="name" type="text" class="form-control" placeholder="Name" id="companyName" required>
       ^^^^^^^^^^^

这将导致浏览器传递 $_POST['name'] 变量中的相关数据
