如何让两个phpmailer联系人表单在同一页上工作？

<?php
require 'phpmailer/PHPMailerAutoload.php';

// 处理第一个表单提交
if (isset($_POST['form1_submit'])) {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];

    // 验证和错误处理
    if (empty($name) || empty($email) || empty($message)) {
        echo "请填写所有必填字段";
    } else if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        echo "请输入有效的电子邮件地址";
    } else {
        // 使用phpmailer发送电子邮件给第一个联系人
        $mail = new PHPMailer;
        $mail->isSMTP();
        $mail->Host = 'smtp.example.com';
        $mail->SMTPAuth = true;
        $mail->Username = 'your-email@example.com';
        $mail->Password = 'your-password';
        $mail->SMTPSecure = 'tls';
        $mail->Port = 587;
        $mail->setFrom('your-email@example.com', 'Your Name');
        $mail->addAddress('recipient1@example.com');
        $mail->Subject = 'New Contact Form Submission';
        $mail->Body = "Name: $name\nEmail: $email\nMessage: $message";

        if ($mail->send()) {
            echo "邮件已成功发送给第一个联系人";
        } else {
            echo "发送邮件时出错：" . $mail->ErrorInfo;
        }
    }
}

// 处理第二个表单提交
if (isset($_POST['form2_submit'])) {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];

    // 验证和错误处理
    if (empty($name) || empty($email) || empty($message)) {
        echo "请填写所有必填字段";
    } else if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        echo "请输入有效的电子邮件地址";
    } else {
        // 使用phpmailer发送电子邮件给第二个联系人
        $mail = new PHPMailer;
        $mail->isSMTP();
        $mail->Host = 'smtp.example.com';
        $mail->SMTPAuth = true;
        $mail->Username = 'your-email@example.com';
        $mail->Password = 'your-password';
        $mail->SMTPSecure = 'tls';
        $mail->Port = 587;
        $mail->setFrom('your-email@example.com', 'Your Name');
        $mail->addAddress('recipient2@example.com');
        $mail->Subject = 'New Contact Form Submission';
        $mail->Body = "Name: $name\nEmail: $email\nMessage: $message";

        if ($mail->send()) {
            echo "邮件已成功发送给第二个联系人";
        } else {
            echo "发送邮件时出错：" . $mail->ErrorInfo;
        }
    }
}
?>
