i oturumda dayalı basit bir PHP shoppingcart yaptı. Bock "PHP & MySQL kullanarak kendi veritabanı odaklı web sitesi oluşturun"
onun 3 dosyaları içerir: kontrol index.php, ve iki şablon içerik catalog.html.php, cart.html.php
i "View your cart" bağlantısını, oturum sona erecek tıklayın ve $ _SESSION ['cart'] zaman sorun otomatik olarak yoketmek ya da bir şey olacak
sorry i cant explain it very will so here is the codes:
/* index.php - the controller*/
$items = array(
array('id' => '1', 'desc' => 'Candian-Australian Dictionary',
'price' => 24.95),
array('id' => '2', 'desc' => 'As-new parachute (never opened)',
'price' => 1000),
array('id' => '3', 'desc' => 'Songs of the Goldfish (2CD set)',
'price' => 19.99),
array('id' => '4', 'desc' => 'Simply JavaScript (SitePoint)',
'price' => 39.95));
session_start();
if (!isset($_SESSION['cart']))
{
$_SESSION['cart'] = array();
}
if (isset($_POST['action']) and $_POST['action'] == 'Buy')
{
// Add item to the end of the $_SESSION['cart'] array
$_SESSION['cart'][] = $_POST['id'];
header('Location: .');
exit();
}
if (isset($_POST['action']) and $_POST['action'] == 'Empty cart')
{
// Empty the $_SESSION['cart'] array
unset($_SESSION['cart']);
header('Location: ?cart');
exit();
}
if (isset($_GET['cart']))
{
$cart = array();
$total = 0;
foreach ($_SESSION['cart'] as $id)
{
foreach ($items as $product)
{
if ($product['id'] == $id)
{
$cart[] = $product;
$total += $product['price'];
break;
}
}
}
include 'cart.html.php';
exit();
}
include 'catalog.html.php';
?>
/* catalog.html.php - display all product*/
<?php include_once $_SERVER['DOCUMENT_ROOT'] .
