Make email sending section as a function in your controller:

public function sendUserMail($email)
{
  $this->load->library('email');

$this->email->from('[email protected]', 'Halalat');
$this->email->to('$email'); 

$this->email->subject('Halalat Newsletter Subscription');
$this->email->message('Testing');   
$this->email->attach('/assests/images/photo1.jpg');
$this->email->send();
echo $this->email->print_debugger();
}

In your action section, add email function call after

if ($query = $this->Users_model->create_member()) {

like:

   $this->sendUserMail($this->input->post("email"));
