使用 Bootstrap 将回复电子邮件添加到联系表单

问：

我不擅长 PHP。我在这里看到另一篇帖子问同样的事情，但代码不同，我尝试了一些东西来看看它是否有效，但我不确定我需要更改什么才能使其正常运行。

我希望客户的电子邮件地址在您点击回复时出现在发送到中。现在，当您点击回复时，它会填写联系表单电子邮件地址。

    // 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>.';
