我一直在网上商店工作。项目的目的是将产品添加到购物车中。客户应该能够更改产品每个数量的尺寸和长度。例子 ：

  • 我出售名为 A 的产品
  • 客户订购5件产品A
  • 所以他应该能够为产品 A 设置 5 个尺寸和长度，因为数量是 5。

然后 TCPDF 也可以通过电子邮件发送创建的发票。

我只需要一些帮助来设置每个数量的大小和长度。请帮助..

如果可能的话，请协助我将这些长度和大小添加到在功能 sendmail 下创建的 pdf

以下是我到目前为止编写的代码...

我试图通过创建另一个会话来做到这一点，但我自己似乎无法完成。

我想让它像...当您将数量更改为 5...所以应该出现 5 个尺寸下拉菜单和 5 个长度下拉菜单。我可以制作下拉菜单，但无法在会话中存储选定的值。

任何帮助表示赞赏。

为了帮助解释这一点，有一个名为 Shopping Cart 的会话。现在有数组项目，如价格大小数量等。现在有一个功能：- 

else if (isset($_POST['update'])) {
//Updates Qty for all items
foreach ($_POST['items_qty'] as $itemID => $qty) {
//If the Qty is "0" remove it from the cart
if ($qty == 0) {
//Remove it from the cart
unset($_SESSION['SHOPPING_CART'][$itemID]);
}
else if($qty >= 1) {
//Update to the new Qty
$_SESSION['SHOPPING_CART'][$itemID]['qty'] = $qty;

}
foreach ($_POST['items_size'] as $itemID => $size) {
//If the Qty is "0" remove it from the cart
if($size >= 1) {
//Update to the new Qty
$_SESSION['SHOPPING_CART'][$itemID]['size'] = $size;

}
}
foreach ($_POST['items_length'] as $itemID => $length) {
//If the Qty is "0" remove it from the cart

//Update to the new Qty
$_SESSION['SHOPPING_CART'][$itemID]['length'] = $length;


}
}

在这里更新每个产品的尺寸和长度。我想要每个数量。例如，如果您选择 5 个数量，客户应该能够选择 5 个尺寸和 5 个长度，无论数量有多大，当前只能选择 1 个。也许这会帮助您理解

首先，您需要通过它们的 id 将项目存储在会话中，而不是通过它们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。您想直接在 中使用该 id $_SESSION['SHOPPING_CART'][ 'item_id' ] = array()，因为这将允许您快速找到该项目并使用它。

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

$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，您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。

但是，我建议使用某种user_id. 在当前的设计中，如果用户不小心关闭了他的浏览器，或者只是在会话到期时回来，他的整个订单都将丢失。

编辑：使用尺寸和长度。

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>';
    }
}

将 echo 替换为用于编辑的输入并将它们放入表单中。
