PHP联系表格电子邮件随机确认号码给用户

Question

我有一个 php 联系表单，当用户提交表单时，我和用户都会收到一封确认电子邮件。我想做的是生成一个随机确认号，并通过电子邮件发送给用户和我以供参考。这是我必须生成随机数的代码：

 <p>Your confirmation number is: <strong><?php echo mt_rand(100000,999999);?></strong>. Keep this for your records.</p>

数字显示在表单上，​​但我的问题是我不知道如何输出此数字以便可以通过电子邮件发送。请原谅我不是程序员，但我确实有一些非常基本的 php 知识。因此，如果有人可以帮助我解决这个问题，我将不胜感激。

这是我学校网站上的表格：http://www.inrf.uci.edu/facility/services/service-request/

这也是我表单中的一些 php 代码：

    // name
    if(trim($_POST['contactName']) === '') {
        $nameError = '<span class="error">Please enter your name.</span>';
        $hasError = true;
    } else {
        $name = trim($_POST['contactName']);
    }
    // email
    if(trim($_POST['email']) === '')  {
        $emailError = '<span class="error">Please enter your email address.</span>';
        $hasError = true;
    } else if (!preg_match("/^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\.[a-z]{2,4}$/i", trim($_POST['email']))) {
        $emailError = '<span class="error">You entered an invalid email address.</span>';
        $hasError = true;
    } else {
        $email = trim($_POST['email']);
    }



    // body ------------------------------------------
    if(!isset($hasError)) {
        $emailTo = get_option('tz_email');
        if (!isset($emailTo) || ($emailTo == '') ){
            $emailTo = 'myemail@email.com';
        }
        $subject = '[Foundry Form] From '.$name;

        $body .= "Name: $name \n\n";
        $body .= "Email: $email \n\n";
        $body .= "Phone: $phone \n\n";

        $headers = 'From: '.$name.' <'.$emailTo.'>' . "\r\n" . 'Reply-To: . $email';
        $headers .= "\r\n" . 'BCC: myotheremail@email.com' . "\r\n";

        wp_mail($emailTo, $subject, $body, $headers);
        $emailSent = true;
    }




  }

Answer 1

您应该做的第一件事是在发送电子邮件之前创建确认号：

$confirmationNumber = mt_rand(100000,999999);

然后将其添加到电子邮件正文中：

$body .= "Confirmation Number: $confirmationNumber\n\n";

然后在页面显示时使用$confirmationNumber：

<p>Your confirmation number is: <strong><?php echo $confirmationNumber; ?></strong>. Keep this for your records.</p>
