using database library write this code to list all fields:
$this->db->list_fields('table')

What you did is to get the datas from the table....
here your table is user so
in your model function do this...
function get_field()
{
$result = $this->db->list_fields('user');
foreach($result as $field)
{
$data[] = $field;
return $data;
}
}
in your controller do this
function get_field()
{
$data['field'] = $this->model_name->get_field();
$this->load->view('view_name',$data);
}
in your view do this
foreach($field as $f)
{
echo $f."<br>"; //this will echo all your fields
}
hope this will help you

The answer given above by Anwar needs modification, there is no need for foreach loop in model function as it will only give the first element despite using foreach, which means the foreach loop is not bringing the fields using $data[], below code should give you 100% result
in your model function do this...
function get_field()
{
$result = $this->db->list_fields('user');
return $result();
}
in your controller do this
function get_field()
{
$data['field'] = $this->model_name->get_field();
$this->load->view('view_name',$data);
}
in your view do this
foreach($field as $f)
{
echo $f."<br>"; //this will echo all your fields
}
