Codeigniter:发送过期邮件

Question

在我的应用程序中，我有一个密码忘记功能，所以如果用户丢失了他们的密码，他们可以点击一个菜单，他们会收到一封带有URL的电子邮件来重置他们的密码。

我想给这个特性加一个时间限制。因此，如果超过一定时间，用户将无法使用电子邮件中发送的相同URL重置密码。

  public function password_post()
  {
    // $email  = trim($this->input->get_post('email'));
    $data = array (
      'username' => $this->input->get_post('username'),
      'idcardno'  => $this->input->get_post('idcardno')
    );
    $result = $this->model->user_exist($data);
    if ($result) {
      $idcardno = $data['idcardno'];
      $data['email'] = $this->db->get_where('mytable', array('idcardno' => $idcardno))->row()->email;
      $this->send_forgot_password($data);
      $this->response(array('success' => 'New password has sent to your email'), 200); // 200 being the HTTP response code
    } else {
      $this->response(array('error' => 'Your account doesnt exist'), 404);
    }
  }

，这是发送电子邮件的方法。

 private function send_forgot_password($data) {
    require(APPPATH.'controllers/mail-master/PHPMailerAutoload.php');
    // $email_encode=urlencode($data['email']);
    $mail = new PHPMailer;
    // $mail->SMTPDebug = 3;
    $mail->isSMTP();
    $mail->Host       = 'mail-id.myweb.com';
    $mail->SMTPAuth   = true;
    $mail->Username   = '[e-mail]';
    $mail->Password   = 'mobile14';
    $mail->SMTPSecure = 'tls';
    $mail->Port       = 25;
    $emailcode = md5($this->config->item('salt') . $username);
    // Email body
    $mail->From     = '[e-mail]';
    $mail->FromName = 'BNI Life';
    $mail->addAddress($data['email']);
    $mail->isHTML(true);
    $mail->Subject = 'Forgot Password';
    $mail->Body    =
    ' ';
    $mail->send();
  }

在user表中，需要存储发送重置密码邮件的时间戳。

然后，当您验证用户对所提供的重置链接的请求时，必须将数据库中存储的时间戳与当前时间戳进行比较。

类似以下语句的内容:

$diff = time() - $mail_sent_timestamp;
//If $diff > 60*60*24*7,
//Diff greater then 7 days; Don't send the new PW to user.
//Else
//Send new password
