Php购物车-每种产品数量的大小和长度

我一直在一家网上商店工作。该项目的目标是将产品添加到购物车中。。客户应能够更改产品每种数量的尺寸和长度。 例如：

• 我卖一种叫a的产品
• 客户订购5件产品A
• 因此，他应该能够为产品A设置5个尺寸和长度，因为数量为5

然后，TCPDF也可以通过电子邮件发送创建的发票

我只是想在设置每种数量的尺寸和长度方面得到一些帮助。请帮忙

如果可能，请帮助我将这些长度和大小添加到sendmail函数下创建的pdf中

下面是我到现在为止写的代码

这里更新了每个产品的尺寸和长度。每种数量我都要。例如，如果您选择5个数量，客户应能够选择5种尺寸和5种长度，无论数量有多大，当前只能选择1个。。也许这有助于您理解

首先，您需要通过项目的id在会话中存储项目，而不是通过项目的名称或自动生成的索引。如果名称更改，您将无法在数据库中找到它们。您希望在

$\u会话['SHOPPING\u CART']['item\u id']=array（）

中直接使用该id，因为这将允许您快速查找项目并使用它

由于同一项有多个实体，因此需要使用更复杂的数组来存储它们。简单的解决方案如下：

$ITEM = array(
    'name' => $_GET['add'],
    'qty' => $_GET['qty'],
    'price' => $_GET['price'] * $_GET['qty'],
    'size' => array_fill(0, $_GET['qty'], $_GET['size']),
    'length' => array_fill(0, $_GET['qty'], $_GET['length']),
    'code' => $_GET['code']
);
$_SESSION['SHOPPING_CART'][ $_GET['item_id'] ] =  $ITEM;

当用户想要更改数据时，可以为大小和长度数组中的每一行创建下拉列表，然后相应地保存它们

然而，我建议使用某种

用户id

将这些数据存储在数据库中。在当前的设计中，若用户意外地关闭了浏览器，或者只是在会话到期时返回，那个么他的整个订单都将丢失

编辑：处理尺寸和长度

foreach ($_SESSION['SHOPPING_CART'] as $item_id => $item)
{
    echo '<p>Name: ' . $item['name'] . ' for ' . $item['price'] . '$</p>';
    foreach($item['size'] as $j => $size)
    {
        echo '<p>#' . $j . ': size ' . $size . ', length ' . $item['length'][$j] . '</p>';
    }
}

foreach（$\u会话['SHOPPING\u CART']作为$item\u id=>$item）
{
回显“Name:”.$item['Name']”代表“$item['price']”。$
”；
foreach（$j=>$size的项目['size']
{
回显“#”。$j.”：大小“$size.”，长度“$item['length'][$j]”。
；
}
}

将echo替换为用于编辑的输入，并将其放入表单中。

澄清您的问题，并指向导致问题的代码。有一个名为“购物车”的会话。现在有了价格、大小、数量等数组项。现在有了一个函数：-嗨，谢谢你的回复。实际上，“大小”=>array\u fill（0，$\u GET['qty']，$\u GET['size']，“长度”=>array\u fill（0，$\u GET['qty']，$\u GET['length']），这会根据数量存储所有大小和长度的选定下拉值吗？此外，存储购物车数据实际上不是必要的，因为客户将进行即时购买。我的意思是，我现在应该如何使用大小和长度？通过像我当前运行的那样运行for-each循环？当客户在购物车中添加5个项目时，您不知道他想要哪种尺寸，我假设他选择了一种尺寸。因此，您可以制作所有大小和长度相同的项目。然后，如果他愿意，他可以编辑它，所以你在一个循环中回显所有大小和长度（因为它们是数组），并在他选择不同选项时更新我只有国家列表，没有链接。您不希望在订单页面显示10个下拉列表。您只想显示数量、一个尺寸和一个长度。然后，若用户选择多个，在购物车页面，他将能够选择大小。不要把它全部放在一个页面上，实际上我的购物车在order.php中，我知道这听起来很奇怪，但无论我是为谁做的，都希望它是这样的。你有什么建议？

foreach ($_SESSION['SHOPPING_CART'] as $item_id => $item)
{
    echo '<p>Name: ' . $item['name'] . ' for ' . $item['price'] . '$</p>';
    foreach($item['size'] as $j => $size)
    {
        echo '<p>#' . $j . ': size ' . $size . ', length ' . $item['length'][$j] . '</p>';
    }
}
