For passing variables into the view you must do this:

 function addPost()
{
    $username = $this->session->userdata('username');
    $data = array(
        'pageTitle' => 'ارسال مطلب',
        'username' => $username
    );
    $this->load->model('category');
    $data['variable'] = $this->category->retrivecat();
    $this->load->view('dashboard/post',$data);
}

Then in the view do print_r($variable);
