Question

我一直在网上商店工作。项目的目标是将产品添加到购物车中。客户应该能够改变尺寸和尺寸。产品每个数量的长度。示例：

我销售名为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也会通过电子邮件发送创建的发票。

我只想帮助设定每个数量的尺寸和长度。请帮助..

如果可能，请帮助我将这些长度和大小添加到创建的pdf中，该文件位于函数sendmail下

以下是我现在写的代码......

<?php

我尝试通过创建另一个会话来做到这一点，但似乎无法自己完成它。

我想把它变成...当你将数量改为5时...所以应该有5个大小的下拉列表和5个长度的下拉列表。我可以制作下拉列表，但无法在会话中存储选定的值。

感谢任何帮助。

为了帮助解释，Theres是一个名为Shopping Cart的会话。现在有数据项目，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;


}
}

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个数量的客户应该能够选择5个尺寸和5个长度当前只能选择1个，无论数量有多大......也许这将有助于您理解

首先，您需要通过ID来存储会话中的项目，而不是通过其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。您希望直接在$_SESSION['SHOPPING_CART'][ 'item_id' ] = array()中使用该ID，因为这样您就可以快速找到该项并使用它。

由于您有多个同一项的实体，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，您可以为size和length数组中的每一行创建下拉列表，然后相应地保存它们。

但是，我会建议将这些数据存储在数据库中user_id。在目前的设计中，如果用户意外关闭了他的浏览器，或者只是在会话到期时回来，他的整个订单将会丢失。

修改：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>';
    }
}

将echo替换为输入以进行编辑，并将它们放入表单中。
