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

Code:

//log the user in
function login()
{
    $username = 'GOD';
    $this->data['username'] = $username;
    $this->data['header'] = $this->load->view('header', $data, TRUE);
    $this->data['midnav'] = $this->load->view('body_m_frontpage', null, TRUE);  
    $this->load->view('front_page', $this->data);
}

@InsiteFX
thanks anyways but i fix it.

Code:

//log the user in
function login()
{
    $data_user['username'] = 'GOD';
    $this->data['header'] = $this->load->view('header', $data_user, TRUE);
    $this->data['midnav'] = $this->load->view('body_m_frontpage', null, TRUE);  
    $this->load->view('front_page', $this->data);
}

Now I know the variable should be in array.

This seems a little complicated. Ha.

To make it global,

Code:

//log the user in
function login()
{
    //$data_user['username'] = $this->input->post('identity');
$this->data['username'] = 'OKAY';
    $this->data['header'] = $this->load->view('header', $this->data, TRUE);
    $this->data['midnav'] = $this->load->view('body_m_frontpage', null, TRUE);  
    $this->load->view('front_page', $this->data);
}
