當物品添加到購物車時,應該顯示該物品的物品ID和數量。在這種情況下,只會從會話中解析數量。物品ID未顯示。另外,當添加不同的物品時,購物車應該顯示另一個具有單獨數量的物品。PHP - 購物車,會話問題
<?php
session_start();
?>
<?php
if (isset($_POST['pid'])) {
$pid = $_POST['pid'];
$wasFound = false;
$i = 0;
if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1){
$_SESSION["cart_array"] = array(1 => array("item_id" => $pid, "quantity" => 1));
} else {
foreach ($_SESSION["cart_array"] as $each_item) {
$i++;
while (list($key, $value) = each($each_item)) {
if ($key == "item_id" && $value == $pid) {
array_splice($_SESSION["cart_array"], $i-1, 1,array(array("item_id" => $pid, "quantity" => $each_item['quantity'] + 1)));
$wasFound = true;
}
}
}
if ($wasFound == false) {
array_push($_SESSION["cart_array"], array("item_id" => $pid, "quantity" => 1));
}
}
}
?>
<?php
if (isset($_GET['cmd']) && $_GET['cmd'] == "emptycart") {
unset($_SESSION["cart_array"]);
}
?>
<?php
$cartOutput = "";
if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1) {
$cartOutput = "<h2 align='center'>Your shopping cart is empty</h2>";
} else {
$i = 0;
foreach ($_SESSION["cart_array"] as $each_item) {
$i++;
$cartOutput .= "<h2>Cart item $i</h2>";
while (list($key, $value) = each ($each_item)) {
$cartOutput .= "key:$value<br />";
}
}
}
?>
有什麼建議嗎? 謝謝
