PHP联系表格-重播到电子邮件

Question

我是PHP的新手，我建立了一个简单的联系表。

我可以正确地从中接收信息，但是当要重播到电子邮件时，不会采取此操作（我必须手动输入）。

我仔细检查过，没有看到错误。

我尝试过的是这个

“回复至：”。 $ email

这是我的PHP代码

<?php
/*
 *  CONFIGURE EVERYTHING HERE
 */

// an email address that will be in the From field of the email.
$from = 'Kontaktformular <email>';

// an email address that will receive the email with the output of the form
$sendTo = 'Kontaktformular | <mail@mydomain.com>';

// subject of the email
$subject = 'Message | domain.com';

// form field names and their translations.
// array variable name => Text to appear in the email
$fields = array('name' => 'Name', 'surname' => 'Vorname', 'phone' => 'Phone', 'email' => 'E-mail', 'message' => 'Nachricht');

// message that will be displayed when everything is OK :)
$okMessage = 'Danke für Ihre KontaktaufnahmeWir melden uns in Kürze bei Ihnen.';

// If something goes wrong, we will display this message.
$errorMessage = 'Error';

/*
 *  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(count($_POST) == 0) throw new \Exception('Form is empty');

    $emailText = "Nachricht | mydomain.com\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' => $errorMessage);
}


if ($responseArray['type'] == 'success') {
    // success redirect


}
else {
    //error redirect

}

我的HTML

<form id="contact-form" method="post" action="/assets/forms/contact_form.php" role="form">

    <div class="messages"></div>

    <div class="controls">

        <div class="row">
            <div class="col-md-6">
                <div class="form-group">
                    <label for="form_name">Name *</label>
                    <input id="form_name" type="text" name="name" class="form-control" placeholder="Name *" required="required" data-error="Firstname is required.">
                    <div class="help-block with-errors"></div>
                </div>
            </div>
            <div class="col-md-6">
                <div class="form-group">
                    <label for="form_lastname">Lastname *</label>
                    <input id="form_lastname" type="text" name="surname" class="form-control" placeholder="Vorname *" required="required" data-error="Lastname is required.">
                    <div class="help-block with-errors"></div>
                </div>
            </div>
        </div>
        <div class="row">
            <div class="col-md-6">
                <div class="form-group">
                    <label for="form_email">Email *</label>
                    <input id="form_email" type="email" name="email" class="form-control" placeholder="E-Mail *" required="required" data-error="Valid email is required.">
                    <div class="help-block with-errors"></div>
                </div>
            </div>

        </div>
        <div class="row">
            <div class="col-md-12">
                <div class="form-group">
                    <label for="form_message">Nachricht *</label>
                    <textarea id="form_message" name="message" class="form-control" placeholder="Nachricht *" rows="4" required="required" data-error="Please, leave us a message."></textarea>
                    <div class="help-block with-errors"></div>
                </div>
            </div>

            <div class="col-md-12">
                <div class="g-recaptcha" data-sitekey=""></div>

                <input type="submit" class="btn btn-success btn-send" value="Senden">
            </div>
        </div>

    </div>

</form>

重点是：我收到了联系表中的电子邮件，但无法重播。我可以，但是我必须手动输入电子邮件。看来“重播到”功能无法正常工作。

预先感谢
