Php Paypal REST API不会在Paypal沙箱或live站点上显示付款金额

RESTAPI工作正常，但它没有显示订单数量 为了使汇总金额不显示，但说明显示？ 我使用下面的代码传递金额和说明

require DIR . '/../bootstrap.php';
use PayPal\Api\Address;
use PayPal\Api\Amount;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\FundingInstrument;
use PayPal\Api\RedirectUrls;
use PayPal\Api\Transaction;


$charge = trim($_POST['amount']);
$currency = trim($_POST['currency']);
$desc = trim($_POST['desc']);
$get_url=trim($_SESSION['get_url']);


$payer = new Payer();
$payer->setPayment_method("paypal");

$amount = new Amount();
$amount->setCurrency($currency);
$amount->setTotal($charge);

$transaction = new Transaction();
$transaction->setAmount($amount);
$transaction->setDescription($desc);





}

"In order summery its showing description but amount is not showing."
Please help me to sort out this problem"
Thank for you help.

创建至少包含一个项目的ItemList并将其添加到事务中。 以下是一个例子：

$payer = new Payer();                          
$payer->setPaymentMethod("paypal");            

$amount = new Amount();                        
$amount->setCurrency($paymentCurrency);        
$amount->setTotal($paymentAmount);             

$item = new Item();                            
$item->setQuantity(1);                         
$item->setName($paymentDescription);           
$item->setPrice($paymentAmount);               
$item->setCurrency($paymentCurrency);          

$itemList = new ItemList();                    
$itemList->setItems(array($item));             

$transaction = new Transaction();              
$transaction->setAmount($amount);              
$transaction->setItemList($itemList);          

$redirectUrls = new RedirectUrls();            
$redirectUrls->setReturnUrl($returnUrl);       
$redirectUrls->setCancelUrl($cancelUrl);       

$payment = new Payment();                      

$payment->setIntent("sale");                   
$payment->setPayer($payer);                    
$payment->setRedirectUrls($redirectUrls);      
$payment->setTransactions(array($transaction));

感谢您的回复，但仍然没有修复，当我在我的页面中添加这两个项目和项目列表时，它会显示空白页面$项目=新项目$项目->设置数量1$item->setName$paymentDescription$项目->设置价格$paymentAmount$项目->设置货币$paymentCurrency$itemList=新的itemList$itemList->setItemsarray$item；感谢您的回复，但仍然没有修复，当我在我的页面中添加这两个项目和项目列表时，它会显示空白页面$项目=新项目$项目->设置数量1$item->setName$paymentDescription$项目->设置价格$paymentAmount$项目->设置货币$paymentCurrency$itemList=新的itemList$itemList->setItemsarray$item；
