Codeigniter send email with image file

Question

How i can send a php email with file & save in codeigniter? If i send the message from the site, i get the contact email, but without the file. My next idea is, that i need the "public function antrag" into the "public function mitgliedschaft", but it is not working.

Antrag = image file

What i try & result>>

Output Email:

Vorname: Testfirstname
Nachname: Testlastname
Email: email@email.com
Steam: Testurl
Antrag: 
Message: Testmessage

Controller

   public function mitgliedschaft() {
        $this->load->library('form_validation');
        $this->form_validation->set_rules('vorname', 'Vorname', 'trim|required');
        $this->form_validation->set_rules('nachname', 'Nachname', 'trim|required');
        $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');
        $this->form_validation->set_rules('steam', 'Steam', 'trim|required');
        $this->form_validation->set_rules("antrag", 'Antrag', "trim|callback_antrag[$id]");
        $this->form_validation->set_rules('message', 'Message', 'trim|required');

        $data['success'] = false;

        if ($this->form_validation->run() == TRUE) {
            @mail(config('webmaster_email'), 'Message from eraseme', ""
                            . "Vorname: $_POST[vorname]\n"
                            . "Nachname: $_POST[nachname]\n"
                            . "Email: $_POST[email]\n"
                            . "Steam: $_POST[steam]\n"
                            . "Antrag: $_POST[antrag]\n"
                            . "Message: $_POST[message]\n"
                            . "");
            $data['success'] = true;
        }
        $this->load->view(__FUNCTION__, $data);
    }

    public function antrag($var, $id) {
        $config['upload_path'] = './cdn/antrag/';
        $config['allowed_types'] = 'gif|jpg|png|jpeg';
        $this->load->library('upload', $config);
        if ($this->upload->do_upload('antrag')) {
            $data = $this->upload->data();
            if ($data['file_name'])
                $this->{$this->model}->antrag = base_url() . '/cdn/antrag/' . $data['file_name'];
        }
        return true;
    }

我在视图的任何地方都看不到表单标签...如果要保存文件，必须为表单分配“ enctype =” multipart / form-data“”属性
