Question

我正在开设e-commerece网站。我正在使用会话作为我购物车系统的一部分。在主要类别/商店页面上，该网站应加载一个类别中的所有项目，除非它已经在他们的购物车中。如果购物车没有设置/是空的，它会自动加载所有商品。

问题是，即使我将一个项目添加到购物车，它仍会显示它。我想出来，由于某种原因，它没有认识到$ _SESSION [＆＃39; cart＆＃39;]被设置。这特别奇怪，因为使用$ _SESSION [＆＃39; cart＆＃39;]的自定义购物车类的标题可以正常工作（它显示正确的项目数。

问题可能是什么？

...和购物车类：

class cart {

public $items = array();


function __construct() {
$pdo = new pdoAccess("localhost","root","");
$counter = 0;
if (isset($_SESSION['cart'])) {  foreach($_SESSION['cart'] as $item) {
$items[$counter] = $pdo->getItemDetails($item, "items");
$counter++;
}
}
}

public function emptyCart() {
session_unset();
session_destroy();
}

public function removeItem($itemID) {
$index = array_search($itemID, $_SESSION['cart']);
unset($_SESSION['cart'][$index]);
}

public function getItemCount() {
if(isset($_SESSION['cart'])) {
return count($_SESSION['cart']);
} else {
return 0;
}
}

public function getSubtotal() {
$total = 0;

foreach($items as $item) {
$total += $item->price;
}

return $total;

}

public function getDiscount() {
$sub = $this->getSubtotal();
if($this->getItemCount >= 2) {
$discount = $sub * .1;
} else {
$discount = 0;
}
return $discount;
}

public function getTotal() {
$sub = $this->getSubtotal;

if($this->getItemCount >= 2) {
$sub +- $this->getDiscount;
}

$total = $sub + SHIPPING;
return $total;


}
}

我将不胜感激任何帮助。提前谢谢！

PHP - $ _SESSION设置不正确吗？
