将回复电子邮件添加到联系表单引导

Question

我不太擅长 PHP，我在这里看到另一篇文章询问同样的事情，但代码不同，我尝试了一些方法来看看它是否有效，但我不确定我需要更改什么才能实现它功能正常。

编辑：抱歉，我希望当您点击回复时，客户的电子邮件会出现在发送中，当您点击回复时，它会填写联系表单的电子邮件地址。

{
    <?php
// require ReCaptcha class
require('recaptcha-master/src/autoload.php');

// configure
// an email address that will be in the From field of the email.
$from = 'Contact form <[email protected]>';

// an email address that will receive the email with the output of the form
$sendTo = 'Contact form <[email protected]>';

// subject of the email
$subject = 'New message from Customer';

// array variable name => Text to appear in the email

$fields = array('name' => 'Name', 'surname' => 'Surname', 'need' => 'Need', 'email' => 'Email', 'message' => 'Message', 'tel' => 'Telephone Number' , 'add' => 'Address' , 'comp' => 'Company Name', 'product' => 'Product'); 



// message that will be displayed when everything is OK :)

$okMessage = 'Contact form successfully submitted. Thank you, I will get back to you soon! <br> You\'ll be redirected in about 5 secs. If not, click <a href="http://www.rs-cryo-equipment.com/contact-us.php">Here.</a>.';



header( "refresh:5;url=http://www.back to/contact-us.php" );

// If something goes wrong, we will display this message.
$errorMessage = 'There was an error while submitting the form. Please try again later';

// ReCaptch Secret
$recaptchaSecret = 'SSHHHHH';

// let's do the sending

// if you are not debugging and don't need error reporting, turn this off by error_reporting(0);
error_reporting(E_ALL & ~E_NOTICE);

try {
    if (!empty($_POST)) {

        // validate the ReCaptcha, if something is wrong, we throw an Exception,
        // i.e. code stops executing and goes to catch() block
        
        if (!isset($_POST['g-recaptcha-response'])) {
            throw new \Exception('ReCaptcha is not set.');
        }

        // do not forget to enter your secret key from https://www.google.com/recaptcha/admin
        
        $recaptcha = new \ReCaptcha\ReCaptcha($recaptchaSecret, new \ReCaptcha\RequestMethod\CurlPost());
        
        // we validate the ReCaptcha field together with the user's IP address
        
        $response = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']);

        if (!$response->isSuccess()) {
            throw new \Exception('ReCaptcha was not validated.');
        }
        
        // everything went well, we can compose the message, as usually
        
        $emailText = "You have a new message from your contact form\n=============================\n";

        foreach ($_POST as $key => $value) {
            // If the field exists in the $fields array, include it in the email
            if (isset($fields[$key])) {
                $emailText .= "$fields[$key]: $value\n";
            }
        }
    
        // All the neccessary headers for the email.
        $headers = array('Content-Type: text/plain; charset="UTF-8";',
            'From: ' . $from,
            'Reply-To: ' . $from,
            'Return-Path: ' . $from,
        );
        
        // Send email
        mail($sendTo, $subject, $emailText, implode("\n", $headers));

        $responseArray = array('type' => 'success', 'message' => $okMessage);
    }
} catch (\Exception $e) {
    $responseArray = array('type' => 'danger', 'message' => $e->getMessage());
}

if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    $encoded = json_encode($responseArray);

    header('Content-Type: application/json');

    echo $encoded;
} else {
    echo $responseArray['message'];
}

}

要修改您的 PHP 代码，使客户的电子邮件成为联系表单中的

Reply-To

地址，您需要首先从 POST 数据中提取电子邮件。假设电子邮件的表单字段名为“email”：

$customerEmail = $_POST['email'] ?? null;

然后，修改标头以包含客户电子邮件中的“回复”，如 [PHP mail() 函数][https://www.php.net/manual/en/function.mb-send- mail.php].

if ($customerEmail) {
    $headers[] = 'Reply-To: ' . $customerEmail;
}

注意：您可能需要在使用之前验证或清理电子邮件。
例如，请参阅“如何在邮寄之前清理 PHP 中的用户输入？”或“PHP 电子邮件验证 - 过滤器验证和过滤器清理”

您的脚本将是：

<?php
// previous code remains unchanged

$customerEmail = filter_var($_POST['email'] ?? null, FILTER_SANITIZE_EMAIL);

// Validate the email
if (!filter_var($customerEmail, FILTER_VALIDATE_EMAIL)) {
    $customerEmail = null; // Invalid email, set to null
}

// previous code remains unchanged

// All the necessary headers for the email.
$headers = array('Content-Type: text/plain; charset="UTF-8";',
    'From: ' . $from,
    'Return-Path: ' . $from,
);

// Add Reply-To header
if ($customerEmail) {
    $headers[] = 'Reply-To: ' . $customerEmail;
}

// (rest of your code)
?>
