paypal SDK 的逻辑问题

Question

我已将 PayPal SDK 与沙盒帐户集成。它适用于我的网站，带有自定义包名称及其价格。比如基本包 79 美元、专业包 150 美元和专业包 400 美元。一旦用户点击继续按钮，它就会重定向到带有基本包和 79 美元价格的 PayPal。对于其他包我必须做什么逻辑？

我尝试将数组 ($basic, $pro, $professional) 插入到项目对象中，但 Setprice() 不接受数组。

我只是坚持在这里输入代码，即使我不知道如何提问非常抱歉。

这是我的 checkout.php

    if ($_POST) {

        $priceBasic= (is_numeric($_POST['b']) ? (int)$_POST['b'] : 89); 
        $pkgBasic = $_POST['basic'];

        $pricePro= (is_numeric($_POST['p']) ? (int)$_POST['p'] : 175);  
        $pkgPro = $_POST['pro'];

        $priceUltra= (is_numeric($_POST['u']) ? (int)$_POST['u'] : 449);    
        $pkgUltra = $_POST['ultra'];

        $shipping = 0.0;
        $total = $priceBasic + $shipping;

        //PAYER INSTANT
         $payer = new Payer();
         $payer->setPaymentMethod('paypal');

        // DEFINING ITEMS

        // $packages = [$pkgBasic, $pkgPro, $pkgUltra];
        // $price = [$priceBasic, $pricePro, $priceUltra];

        $item = new Item();
        $item->setName($packages)->setCurrency('USD')->setQuantity(1)-
        >setPrice($priceBasic);

        //PACKAGES LIST
        $itemList = new ItemList();
        $itemList->setItems([$item]);

         $details = new Details();
         $details->setShipping($shipping)
        ->setSubTotal($total);

        $amount = new Amount();
        $amount->setCurrency('USD')->setTotal($total)
        ->setDetails($details);
        $transaction = new Transaction();

        $transaction->setAmount($amount)->setItemList($itemList)-
        >setDescription('Hello Hash Thanks for first paypal')-
        >setInvoiceNumber(uniqid());

        $redirectUrls = new RedirectUrls();
        $redirectUrls->setReturnUrl(SITE_URL.'/pay.php?success=true')
        ->setCancelUrl(SITE_URL.'/pay.php?success=false');


        $payment = new Payment();
        $payment->setIntent('sale')->setPayer($payer)
       ->setRedirectUrls($redirectUrls)->setTransactions([$transaction]);


       try {
         $payment->create($paypal);
       } catch (Exception $e) {

       die($e);

     }

     $aprovalUrl = $payment->getApprovalLink();

     // echo $aprovalUrl;
     header("location:".$aprovalUrl);

  }

?>`

您可以使用 switch case 在价格之间切换。希望这可以帮助。

$package_type = $_POST['package_type'];

switch($package_type) {
    case "basic":
        $price = 89;
    break;
    case "pro":
        $price = 175;
    break;
    case "ultra":
        $price = 449;
    break;
}


$shipping = 0.0;
$total = $priceBasic + $shipping;

//PAYER INSTANT
 $payer = new Payer();
 $payer->setPaymentMethod('paypal');

// DEFINING ITEMS

// $packages = [$pkgBasic, $pkgPro, $pkgUltra];
// $price = [$priceBasic, $pricePro, $priceUltra];

$item = new Item();
$item->setName($packages)->setCurrency('USD')->setQuantity(1)-
>setPrice($price);


//PACKAGES LIST
$itemList = new ItemList();
$itemList->setItems([$item]);

 $details = new Details();
 $details->setShipping($shipping)
->setSubTotal($total);


$amount = new Amount();
$amount->setCurrency('USD')->setTotal($total)
->setDetails($details);
$transaction = new Transaction();

 $transaction->setAmount($amount)->setItemList($itemList)-
 >setDescription('Hello Hash Thanks for first paypal')-
 >setInvoiceNumber(uniqid());

 $redirectUrls = new RedirectUrls();
 $redirectUrls->setReturnUrl(SITE_URL.'/pay.php?success=true')
 ->setCancelUrl(SITE_URL.'/pay.php?success=false');


 $payment = new Payment();
 $payment->setIntent('sale')->setPayer($payer)
->setRedirectUrls($redirectUrls)->setTransactions([$transaction]);


try {
$payment->create($paypal);
} catch (Exception $e) {

die($e);

}

  $aprovalUrl = $payment->getApprovalLink();

// echo $aprovalUrl;
header("location:".$aprovalUrl);

?>

切换案例示例，检查此代码是否适合您。这就是您必须根据计划切换价格的方式。

<?php
$package_type = 'pro';
$price = 0;

switch($package_type) {
    case "basic":
        echo 'hai';
    break;
    case "pro":
        $price = 175;
    break;
    case "ultra":
        $price = 449;
    break;
}
echo $price;

?>
