I am new to codeigniter model, i try to follow steps in docs to load all user registered in my db.

This is my model: user.php

class User extends Model {      function user() {          parent::Model();      }      function alluser() {          $query = $this->db->query("select * from user limit 0,5"); //Line 30 error as in my IDE located in this line          return $query->result();      } } 

This is my controller: home.php

class home extends Controller {  function index() {      parent::Controller();  } function alluser() {     $this->load->model('User');     $result = $this->User->showusers();     if ($result->num_rows()>0) {         foreach ($result as $row) {             echo "ID:".$row->userid." ".$row->userpenname."<br />";             echo $row->userfirstname." ".$row->userlastname."<br />";         }       }    } } 

it showing error:

A PHP Error was encountered  Severity: Notice  Message: Undefined property: User::$db  Filename: models/user.php  Line Number: 30

You have to load the db library first. In autoload.php add :

$autoload['libraries'] = array('database'); 

Also, try renaming User model class for "User_model".
