php - 如何让自己发送一份副本复选框

Question

我需要一个可以给自己发送副本的复选框。例如，他们填写了联系表格并希望将副本发送给他们自己，他们选中该框，它将通过电子邮件发送给我，并且仍然通过电子邮件发送给他们。这是我的PHP：

 //If the form is submitted
  if(isset($_POST['submit'])) {

    //Check to make sure that the name field is not empty
    if(trim($_POST['contactname']) == '') {
      $hasError = true;
    } else {
      $name = trim($_POST['contactname']);
    }

    //Check to make sure that the subject field is not empty
    if(trim($_POST['subject']) == '') {
      $hasError = true;
    } else {
      $subject = trim($_POST['subject']);
    }

    //Check to make sure that the subject field is not empty
    if(trim($_POST['weburl']) == '') {
      $site = trim($_POST['weburl']);
    }

    //Check to make sure sure that a valid email address is submitted
    if(trim($_POST['email']) == '')  {
      $hasError = true;
    } else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email']))) {
      $hasError = true;
    } else {
      $email = trim($_POST['email']);
    }

    //Check to make sure comments were entered
    if(trim($_POST['message']) == '') {
      $hasError = true;
    } else {
      if(function_exists('stripslashes')) {
        $comments = stripslashes(trim($_POST['message']));
      } else {
        $comments = trim($_POST['message']);
      }
    }

    //If there is no error, send the email
    if(!isset($hasError)) {
      $emailTo = 'myemail@domain.com'; // Put your own email address here
      $body = "Name: $name \n\nEmail: $email \n\nSubject: $subject \n\nSite:  \n\nComments:\n $comments";
      $headers = 'From: BTSyncrets Contact <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;

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

这是我的联系表格代码：

<div id="contact" class="offset4 login">
        <form style="margin-top: 5% !important;" method="post" action="index.php" id="contactform">
          <fieldset class="well">

              </div>
            </div>

                </select>
              </div>
            </div>

            <div class="clearfix">
              <label for="message">Message<span class="help-required">*</span></label>
              <div class="input">

              </div>
            </div>


            <label class="checkbox">
              <input type="checkbox" name="copy" value="1" /> Send Yourself a copy
            </label>


            <div class="actions">
              <input type="submit" value="Send Your Message" name="submit" id="submitButton" class="btn btn-inverse" title="Click here to submit your message!" />
              <input type="reset" value="Clear Form" class="btn btn-danger" title="Remove all the data from the form." />
            </div>
          </fieldset>
        </form>
      </div><!-- form -->
