Sends email two times and activation problem

[eluser]Unknown[/eluser]
Hi there,

i face two problems and could not solve them.

I send email to users for registration.However, it sends email two times


Here is the code

Code:

public function kayitOnay() {
    

        $username = $this->input->post('username');
        $email = $this->input->post('email');
        $password = $this->input->post('password');

        $data = array();

        $data['username'] = $username;
        $data['email'] = $email;
        $data['password'] = $password;

        $activationCode = $this->randomString(10);

        $this->load->view('kayit/kayitOnay', $data);
        $this->kayitmodel->uyeEkle($username, $email, $password, $activationCode);

      
        $config = Array(
            'protocol' => 'smtp',
            'smtp_host' => 'ssl://smtp.googlemail.com',
            'smtp_port' => 465,
            'smtp_user' => '[email protected]',
            'smtp_pass' => '********',
            'mailtype' => 'html'
        );
        
        
  

        $this->load->library('email', $config);
        $this->email->set_newline("\r\n");

        
        $dataLink['link'] =  "/kayit/kayitEmailOnay/$activationCode";
      
        
        
        $this->email->from('[email protected]', 'Pasaj.com');
        $this->email->to('[email protected]');
        $this->email->subject('Hesap Aktivasyonu');
        $email = $this->load->view('kayit/kayitOnayMail', $dataLink, TRUE);
        $this->email->message($email);
        $this->email->send();
    }

and in email i use kayitOnayMail template as you see above i send a link to this template to complete the registration process

but when user click it it sends kayitOnay why :S This is the code of it

Code:

public function kayitEmailOnay() {

        $registrationCode = $this->uri->segment(3);

        if ($registrationCode == '') {
            echo "URLde onay kodu yok";
        }


        $registrationConfirmed = $this->kayitmodel->uyeOnay($registrationCode);

        if ($registrationConfirmed)
             echo "oke";
        else
            $this->load->view('kayit/kayitHata');
    }
