发送电子邮件使用的PHPMailer

Question

我想使用的PHPMailer这里我控制器代码

public function register(){ $this->form_validation->set_rules('username', 'Usename Name', 'trim|required|min_length[3]|max_length[30]'); 
    $this->form_validation->set_rules('email', 'Email ID', 'trim|required|valid_email|is_unique[employer_registration.email]'); 
    $this->form_validation->set_rules('mobile', 'Mobile', 'trim|required|numeric'); 
    $this->form_validation->set_rules('password', 'Password', 'trim|required|md5'); 
    if ($this->form_validation->run() == FALSE) 
    { 
     $this->load->view('employer/emp_register'); 
    } 
    else 
    { 
     $data = array(
      'username' => $this->input->post('username'), 
      'email' => $this->input->post('email'), 
      'mobile' => $this->input->post('mobile'), 
      'password' => $this->input->post('password') 
     ); 
     $email = $this->input->post('email'); 
     $username = $this->input->post('username'); 
    // insert form data into database 
     if ($this->Employer_model->insertUser($data)) 
     { 
      require 'PHPMailerAutoload.php'; 
      require 'class.phpmailer.php'; 
      $mail = new PHPMailer; 
      $mail->isSMTP(); 
      $mail->SMTPAuth = true; 
    $subject = 'Testing Email'; 
      $username = $username; 
      $email = $email; 
      $body = "Thank you for register your username is $username"; 
      $mail->AddAddress($email); 
      $mail->IsMail(); 
      $mail->From = 'domainname.com'; 
      $mail->IsHTML(true); 
      $mail->Subject = $subject; 
      $mail->Body = $body; 
      $mail->Send(); 

      if(!$mail->send()) 
      { 
       echo "<script>alert('Sorry! mail not sent')</script>"; 
       echo 'Mailer Error: ' . $mail->ErrorInfo; 
      } 
      else 
       { 
       echo "<script>alert('Email sent to $email mail id')</script>"; 
       } 
    }}} 

我已经下载PHPMailer的文件夹，从GitHub发送邮件，包括它在我的项目PHPMailerAutoload文件仍然成功注册我无法发送邮件后注册电子邮件ID。我得到错误，如梅勒错误：无法实例化邮件功能。

您使用SMTP身份验证，但是你没有实际定义任何主机，这是必需的：

例：$mail->Host = "smtp.example.com";

端起$mail->isSMTP();后与您的域名改变。

此外，您还可以选择像这样提供用户名和密码，如果你需要：

$mail->Username = 'username'; $mail->Password = 'password';
