Remove the trailing ?> and make sure there is no whitespace before the <?php tag.

still nothing: here is the full error I'm getting:
load->model('Users'); } function index(){ // store data for being displayed on view file $data['users']=$this->Users->getUsers(); $data['numusers']=$this->Users->getNumUsers(); $data['title']='Displaying user data'; $data['header']='User List'; // load 'users_view' view $this->load->view('users_view',$data); } }
A PHP Error was encountered

Please, post the entire controller class and indent and highlight your code using bbcode in the formatting bar.

Code:
class Users extends Controller{
function Users (){
// load controller parent
parent::Controller();
// load 'Users' model
$this->load->model('Users');
}
function index(){
// store data for being displayed on view file
$data['users']=$this->Users->getUsers();
$data['numusers']=$this->Users->getNumUsers();
$data['title']='Displaying user data';
$data['header']='User List';
// load 'users_view' view
$this->load->view('users_view',$data);
}
}I got this tutorial from devshed

I don't see any error. This is a stupid question, I know, but, have you put <?php before the class statement?
Code:
<?php
class Users extends Controller{Cristian Gilè

Remove only the closing tag. The right code is:
Code:
<?php
class Users extends Controller{
function Users (){
// load controller parent
parent::Controller();
// load 'Users' model
$this->load->model('Users');
}
function index(){
// store data for being displayed on view file
$data['users']=$this->Users->getUsers();
$data['numusers']=$this->Users->getNumUsers();
$data['title']='Displaying user data';
$data['header']='User List';
// load 'users_view' view
$this->load->view('users_view',$data);
}
}As InsiteFX said before, make sure there is no whitespace before the <?php opening tag.

not sure if this is right or means anything I named my files:
controller file: users.php
model: users_model.php
view: users_view.php
I thought that was the correct naming convention....

so I renamed the model to just users.php and now I get this error...this db table only has two records in it like the tutorial ...
load->database(); } function getAllUsers(){ $query=$this->db->get('users'); if($query->num_rows()>0){ // return result set as an associative array return $query->result_array(); } } function getUsersWhere($field,$param){ $this->db->where($field,$param); $query=$this->db->get('users'); // return result set as an associative array return $query->result_array(); } // get total number of users function getNumUsers(){ return $this->db->count_all('users'); } }
