Codeigniter index parameter - php

Question

This is not the only controller in the folder. I already deleted index.php.
but once i add this part of a function for a shopping cart
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Product extends CI_Controller
{
public function index($index = 0)
{
$data['listProduct'] = $this->mproduct->findAll();
$this->load->view('template/header.php', $data);
$this->load->view('index', $data);
}
}
it gives me this error
Message: Undefined property: Product::$mproduct
Filename: controllers/product.php
Line Number: 7
here is my model
<?php
class MProduct extends CI_Model
{
function _construct()
{
parent::_construct();
}
function findAll()
{
return $this->db->get('product')->result();
}
function find($id)
{
$this->db->where('id', $id);
return $this->db->get('product')->row();
}
}

Answer 1

You need to load the model first before calling it.
Also the first letter should be capitalized with rest of the name should be in lowercase.
Class names must have the first letter capitalized with the rest of
the name lowercase. Make sure your class extends the base Model class.

Add this:
$this->load->model ( 'Mproduct' );
$data['listProduct'] = $this->Mproduct->findAll();
Full code :
Controller : controllers/Product.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Product extends CI_Controller {
public function index()
{
$this->load->model ( 'Mproduct' );
$data['listProduct'] = $this->Mproduct->findAll();
$this->load->view('template/header.php', $data);
$this->load->view('index', $data);
}
}
Model : models/Mproduct.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Mproduct extends CI_Model {
function _construct()
{
parent::_construct();
}
function findAll()
{
echo 'model';
}
function find($id)
{
echo 'model';
}
}
