}

function getAllUsers(){

$query=$this->db->get('admin_user');

if($query->num_rows()>0){

// return result set as an associative array

return $query->result_array();

}

}

}

?>

im having this error

Fatal error: Call to a member function getUsersWhere() on a non-object in C:\xampp\htdocs\printone\application\controllers\users.php on line 16

what could be the fault?

You misnamed your controller constructor, so it isn't being called and your model isn't being loaded.

Change

function __Users(){

to

function __construct(){
