Problem With Cart Object

[anointing]

Hi,

 

I'm from a java background newly entering php. I want to implement a simple cart object which contains an array of items. The items themselves are to be encapsulated in an item object.

 

I'm using PHP Version 5.2.5 with Apache 2.2. The problem is cart.php which is supposed to add an item to a cart object simply does not see both classes. I know something needs to be done to give php access to the classes. Not sure exactly what.

 

Please advice.

 

 

Both item and cart classes are inthe same root directory

 

========

Here is the Item class contained in item.php:

 

<?php

class Item

{

    var $ref;          // Cake reference number

    var $name;        // Cake name

    var $order;      // Cake oder details

    var $cost;      // Cost of order

    var $qty;      // Number of cakes ordered

 

 

   

    // instantiate object

 

    function __construct($ref, $name, $order, $cost, $qty)

    {

 

        $this->ref = $ref;

        $this->name = $name;

        $this->order = $order;

        $this->cost = $cost;

        $this->qty = $qty;

    }     

 

 

    // get reference

    function get_ref()

    {

        return $this->ref;

    }

 

 

    // get cake name

    function get_name()

    {

        return $this->name;

    }

 

 

    // get cake order

    function get_order()

    {

        return $this->order;

    }

 

 

    // get cake costs

    function get_cost()

    {

        return $this->cost;

    }

 

 

    // get cake quantity

    function get_qty()

    {

        return $this->qty;

    }

 

     

}

?>

 

========

 

Here is the Cart class contained in cart.php:

 

<?php

session_start();

include("item.php");

 

 

$items;

 

 

 

function __construct()

{

 

    $this->items = array();

}     

 

 

 

 

function addItem($ref, $name, $order, $cost, $qty)

{

    if(count($this->items)==0)

    {

        $anItem= new Item($ref, $name, $order, $cost, $qty);

        $this->items[$ref] = $anItem;

        //$_SESSION['cart'] = $this;

    }

    else

    {     

        foreach($this->items[] as $k => $v)

        {

          $itemobject= (Item)$this->items[$k];

          if($itemobject->ref==$k)

          {

              echo "This item has already been selected";

          }

        }

     

 

    }

}

you need on your cart class

 

class cart extends item
{
