我正在开发一个简单的订单系统。
我所坚持的代码如下:
if (isset($_GET['cart']))
{
$cart = array();
$total = 0;
foreach ($_SESSION['cart'] as $id)
{
foreach ($items as $product)
{
if ($product['id'] == $id)
{
$cart[] = $product;
$total += $product['price'];
break;
}
}
}
include 'cart.html.php';
exit();
}
这是建立在预设数组上的代码。我正在 mysql 中使用一个包含几列的表。
我决定如下:
if (isset($_GET['cart']))
{
$cart = array();
$total = 0;
foreach ($_SESSION['cart'] as $id)
{
while($row = mysql_fetch_assoc($productsSql)) {
foreach ($row as $product)
{
if ($product['id'] == $id)
{
$cart[] = $product;
$total += $product['price'];
break;
}
}
}
include 'cart.html.php';
exit();
}}
为了显示这个“购物车”,我决定这样做:
foreach ($cart as $item) {
$pageContent .= '
<tr>
<td>'.$item['desc'].'</td>
<td>
R'.number_format($item['price'], 2).'
</td>
</tr>
';
}
所有这一切似乎都是以一种方式生成我的购物车,在查看时它仅显示项目 ID 的列表,例如在描述和价格应该在的地方,我只得到两个字段中的商品 id...我还得到 0 的总价。
谁能发现我在这里出错的地方吗?
或者至少尝试给我一些意见,以便我朝着正确的方向前进!
Thanks!!
