Question

我遇到了一些代码问题。我正在为我的网站制作一个捐赠页面，我不知道如何去展示它的“item_name”部分。我有几种可能的捐赠选项，我想在重定向到付款时显示他们选择在item_name中显示的选项。这就是我所拥有的：

        $price = '6.50';
    if($_GET['prod'] == 1) //Price for package 1 (Regular Donator)
        $price = '6.50';
    if($_GET['prod'] == 2) //Price for package 2 (Extreme Donator)
        $price = '12.50';
    if($_GET['prod'] == 3) //Price for package 3 (10 SoF Spins)
        $price = '2.50';
    if($_GET['prod'] == 4) //Price for package 4 (20 SoF Spins)
        $price = '4.00';
    if($_GET['prod'] == 5) //Price for package 5 (Fight Kiln Completion)
        $price = '5.50';
    if($_GET['prod'] == 6) //Price for package 6 (1 Ragged Gold Key)
        $price = '2.00';
    if($_GET['prod'] == 7) //Price for package 7 (4 Ragged Gold Keys)
        $price = '9.99';
    if($_GET['prod'] == 8) //Price for package 8 (12 Ragged Gold Keys)
        $price = '20.00';
    if($_GET['prod'] == 9) //Price for package 9 (28 Ragged Gold Keys)
        $price = '40.00';

  $p->add_field('custom', $_GET['username']);
  $p->add_field('business', 'dtordik@gmail.com'); //edit to your email
  $p->add_field('return', $this_script.'?action=success');
  $p->add_field('cancel_return', $this_script.'?action=cancel');
  $p->add_field('notify_url', $this_script.'?action=ipn');
  $p->add_field('item_name', 'Package '.$_GET['prod']);
  $p->add_field('item_number', $_GET['prod']);
  $p->add_field('currency_code', 'USD');
  $p->add_field('amount', $price);
  //$p->add_field('quantity', $_GET['amm']);
  $p->add_field('lc', 'GB');
  $p->submit_paypal_post(); // submit the fields to paypal
  //$p->dump_fields();      // for debugging, output a table of all the fields
  break;

您会看到 $ p-＆gt; add_field（'item_name'，'Package'。$ _ GET ['prod']）; ，它会抓住该号码，然后会显示在paypal网站上作为“包1”我怎样才能做到这一点，如果有人选择'prod'1，它可以成为“常规捐赠者”，“prod”2作为“极端捐赠者”等等。我不知道我是否过度思考，但任何帮助将不胜感激，谢谢！

这段代码效率有点低，如果优化解决方案就会直截了当。

定义所有产品，价格和标签的清单。

$products = array(
    1 => array(
        "price" => "6.00",
        "label" => "Regular Donator"
    ),
    2 => array(
        "price" => "60.00",
        "label" => "Extreme Donator"
    ),
    3 => array(
        "price" => "0.00",
        "label" => "Cheap bastard"
    )
);

$product = $_GET["prod"];
$price = $products[$product]["price"];
$label = $products[$product]["label"];

$p->add_field('item_name', $label);
$p->add_field('item_number', $product);
$p->add_field('amount', $price);
// etc

如何更改此设置以使if语句显示在Paypal上
