1.wfcart, som har alle funksjoner og liknende

2. demo.php, en demo for wfcart.php

 

spørsmålet er som følger: demoen inneholder tre eksempel produkter. 1. a bar of soap. 2. cheese 3. Pizza. Jeg vil endre disse slik at jeg kan hente ut resultatene fra en database isteden, hvordan skal jeg gjøre dette?

 

 

wfcart.php:

class wfCart {

var $total = 0;

var $itemcount = 0;

var $items = array();

var $itemprices = array();

var $itemqtys = array();

var $iteminfo = array();

 

function cart() {} // constructor function

 

function get_contents()

{ // gets cart contents

$items = array();

foreach($this->items as $tmp_item)

{

$item = FALSE;

 

$item['id'] = $tmp_item;

$item['qty'] = $this->itemqtys[$tmp_item];

$item['price'] = $this->itemprices[$tmp_item];

$item['info'] = $this->iteminfo[$tmp_item];

$item['subtotal'] = $item['qty'] * $item['price'];

$items[] = $item;

}

return $items;

} // end of get_contents

 

 

function add_item($itemid,$qty=1,$price = FALSE, $info = FALSE)

{ // adds an item to cart

if(!$price)

{

$price = wf_get_price($itemid,$qty);

}

 

if(!$info)

{

$info = wf_get_info($itemid);

}

 

if($this->itemqtys[$itemid] > 0)

{ // the item is already in the cart..

// so we'll just increase the quantity

$this->itemqtys[$itemid] = $qty + $this->itemqtys[$itemid];

$this->_update_total();

} else {

$this->items[]=$itemid;

$this->itemqtys[$itemid] = $qty;

$this->itemprices[$itemid] = $price;

$this->iteminfo[$itemid] = $info;

}

$this->_update_total();

} // end of add_item

 

 

function edit_item($itemid,$qty)

{ // changes an items quantity

 

if($qty < 1) {

$this->del_item($itemid);

} else {

$this->itemqtys[$itemid] = $qty;

// uncomment this line if using

// the wf_get_price function

// $this->itemprices[$itemid] = wf_get_price($itemid,$qty);

}

$this->_update_total();

} // end of edit_item

 

 

function del_item($itemid)

{ // removes an item from cart

$ti = array();

$this->itemqtys[$itemid] = 0;

foreach($this->items as $item)

{

if($item != $itemid)

{

$ti[] = $item;

}

}

$this->items = $ti;

$this->_update_total();

} //end of del_item

 

 

function empty_cart()

{ // empties / resets the cart

$this->total = 0;

$this->itemcount = 0;

$this->items = array();

$this->itemprices = array();

$this->itemqtys = array();

$this->itemdescs = array();

} // end of empty cart

 

 

function _update_total()

{ // internal function to update the total in the cart

$this->itemcount = 0;

$this->total = 0;

if(sizeof($this->items > 0))

{

foreach($this->items as $item) {

$this->total = $this->total + ($this->itemprices[$item] * $this->itemqtys[$item]);

$this->itemcount++;

}

}

} // end of update_total

 

}

?>

 

 

demo.php:

 

<?php

// You must included wfcart.php BEFORE you start the session.
