Input data otomatis ke database

gan cara buat input data otomatis ke database gimana ya..? misal di database ada kolom yang defaultnya 0 terus jika pengguna login nambah jadi 1

**Controller**

public function login()
	{
		$this->data['title'] = $this->lang->line('login_heading');

		// validate form input
		$this->form_validation->set_rules('identity', str_replace(':', '', $this->lang->line('login_identity_label')), 'required');
		$this->form_validation->set_rules('password', str_replace(':', '', $this->lang->line('login_password_label')), 'required');

		if ($this->form_validation->run() === TRUE)
		{
			// check to see if the user is logging in
			// check for "remember me"
			$remember = (bool)$this->input->post('remember');

			if ($this->ion_auth->login($this->input->post('identity'), $this->input->post('password'), $remember))
			{
				//if the login is successful
				//redirect them back to the home page
				$this->session->set_flashdata('message', $this->ion_auth->messages());
				redirect('auth/index', 'refresh');
			}
			else
			{
				// if the login was un-successful
				// redirect them back to the login page
				$this->session->set_flashdata('message', $this->ion_auth->errors());
				redirect('auth/login', 'refresh'); // use redirects instead of loading views for compatibility with MY_Controller libraries
			}
		}
		else
		{
			// the user is not logging in so display the login page
			// set the flash data error message if there is one
			$this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');

			$this->data['identity'] = [
				'name' => 'identity',
				'id' => 'identity',
				'type' => 'text',
				'value' => $this->form_validation->set_value('identity'),
			];

			$this->data['password'] = [
				'name' => 'password',
				'id' => 'password',
				'type' => 'password',
			];

			$this->_render_page('user' . DIRECTORY_SEPARATOR . 'form_login', $this->data);
		}
	}

**Model**

public function login($identity, $password, $remember=FALSE)
	{
		$this->trigger_events('pre_login');

		if (empty($identity) || empty($password))
		{
			$this->set_error('login_unsuccessful');
			return FALSE;
		}

		$this->trigger_events('extra_where');

		$query = $this->db->select($this->identity_column . ', email, id, password, active, last_login')
						  ->where($this->identity_column, $identity)
						  ->limit(1)
						  ->order_by('id', 'desc')
						  ->get($this->tables['users']);

		if ($this->is_max_login_attempts_exceeded($identity))
		{
			// Hash something anyway, just to take up time
			$this->hash_password($password);

			$this->trigger_events('post_login_unsuccessful');
			$this->set_error('login_timeout');

			return FALSE;
		}

		if ($query->num_rows() === 1)
		{
			$user = $query->row();

			if ($this->verify_password($password, $user->password, $identity))
			{
				if ($user->active == 0)
				{
					$this->trigger_events('post_login_unsuccessful');
					$this->set_error('login_unsuccessful_not_active');

					return FALSE;
				}

				$this->set_session($user);

				$this->update_last_login($user->id);

				$this->clear_login_attempts($identity);
				$this->clear_forgotten_password_code($identity);

				if ($this->config->item('remember_users', 'ion_auth'))
				{
					if ($remember)
					{
						$this->remember_user($identity);
					}
					else
					{
						$this->clear_remember_code($identity);
					}
				}

				// Rehash if needed
				$this->rehash_password_if_needed($user->password, $identity, $password);

				// Regenerate the session (for security purpose: to avoid session fixation)
				$this->session->sess_regenerate(FALSE);

				$this->trigger_events(['post_login', 'post_login_successful']);
				$this->set_message('login_successful');

				return TRUE;
			}
		}

		// Hash something anyway, just to take up time
		$this->hash_password($password);

		$this->increase_login_attempts($identity);

		$this->trigger_events('post_login_unsuccessful');
		$this->set_error('login_unsuccessful');

		return FALSE;
