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

        $this->load->model('register_model');

        $data['list']=$this->register_model->add($username, $password);

        $this->load->view('register_display', $data);
    }

        setLayout(new GridBagLayout());

        gbc.insets = new Insets(5,5,5,5);

        homeMessage = new JLabel("Please select an option below:");
        gbc.gridx = 0;
        gbc.gridy = 0;
        add(homeMessage, gbc);

        regButton = new JButton("Register");
        gbc.gridx = 0;
        gbc.gridy = 1;
        gbc.fill = GridBagConstraints.HORIZONTAL;

        regButton.addActionListener(new ActionListener() …
