Question

我在我的网站上使用Paypal Express Checkout并收到此错误：

SetExpressCheckout API call failed. Detailed Error Message: The totals of the cart item amounts do not match order amounts.Short Error Message: Transaction refused because of an invalid argument. See additional error messages for details.Error Code: 10413Error Severity Code: Error

当我输入1的数量时，一切正常，但当我输入2或更多时，我得到错误。

我正在使用SMARTY Templating。

            <form class="pull-right" action="../Checkout/paypal_ec_redirect.php" method="POST">
            <input type="hidden" name="L_PAYMENTREQUEST_0_NAME0" value="{$product_naam}"></input>
                <input type="hidden" name="L_PAYMENTREQUEST_0_AMT0" value="{$product_productprijs}"></input>
                <input type="hidden" name="L_PAYMENTREQUEST_0_QTY0" value="{$product_aantal}"></input>

                <input type="hidden" name="PAYMENTREQUEST_0_ITEMAMT" value="{$product_subtotaal}"></input>
                <input type="hidden" name="PAYMENTREQUEST_0_TAXAMT" value="{$product_btw}"></input>
                <input type="hidden" name="PAYMENTREQUEST_0_AMT" value="{$product_totaalprijs}"></input>
                <input type="hidden" name="currencyCodeType" value="EUR"></input>
                <input type="hidden" name="paymentType" value="Sale"></input>

                <input type="image" src="https://www.paypalobjects.com/webstatic/en_US/i/buttons/checkout-logo-large.png" alt="Check out with PayPal"></input>
            </form>
        </div>
    </div>
</div>

这是PHP：

foreach ($getproduct as $row) {
    $productaantal = $aantalbesteld;
    $productnaam = $row['naam'];
    $productprijs = $row['prijs'];
    $btwtarief = $row['btw_tarief'];
    $btwbedrag = ($productprijs*$aantalbesteld)/100*$btwtarief;
    $subtotaal = ($productprijs*$aantalbesteld)-$btwbedrag;
    $totaalprijs = $productprijs*$aantalbesteld;
}


//Product
$smarty->assign('product_naam', $productnaam);
$smarty->assign('product_aantal', $productaantal);
$smarty->assign('product_prijs', money_format('%.2n', $productprijs));
$smarty->assign('product_subtotaal', money_format('%.2n', $subtotaal));
$smarty->assign('product_btw', money_format('%.2n', $btwbedrag));
$smarty->assign('product_totaalprijs', money_format('%.2n', $totaalprijs));
$smarty->assign('product_bestelknop', 'Bestellen');

编辑：即使这不起作用：

            <form class="pull-right" action="../Checkout/paypal_ec_redirect.php" method="POST">
                <input type="hidden" name="L_PAYMENTREQUEST_0_NAME0" value="{$product_naam}"></input>
                <input type="hidden" name="L_PAYMENTREQUEST_0_AMT0" value="5.00"></input>
                <input type="hidden" name="L_PAYMENTREQUEST_0_QTY0" value="2"></input>

                <input type="hidden" name="PAYMENTREQUEST_0_ITEMAMT" value="10.00"></input>
                <input type="hidden" name="PAYMENTREQUEST_0_TAXAMT" value="2.10"></input>
                <input type="hidden" name="PAYMENTREQUEST_0_AMT" value="12.10"></input>
                <input type="hidden" name="currencyCodeType" value="EUR"></input>
                <input type="hidden" name="paymentType" value="Sale"></input>

                <input type="image" src="https://www.paypalobjects.com/webstatic/en_US/i/buttons/checkout-logo-large.png" alt="Check out with PayPal"></input>
            </form>

Answer 1

它表示当它们乘以数量和数量时，它不会加起来指定为totalamount

$btwbedrag = ($productprijs*$aantalbesteld)/100*$btwtarief;
$subtotaal = ($productprijs*$aantalbesteld)-$btwbedrag;
$totaalprijs = $productprijs*$aantalbesteld;

您的增值税的计算方法是将总价格金额的1％乘以增值税税率。这假设您的产品金额是专属增值税。

然后在下一行中从$subtotaal中删除增值税，为什么？它首先没有被包括在内。或者如果它是那么你应该除以121而不是100。

$totaalprijs似乎是在假设已包含增值税的情况下计算的。

您是否检查了网页来源中隐藏字段的值？

Answer 2

当我将数量更改为2时，这是发送给PayPal的请求。

paymentrequest_0_currencycode   "EUR"
paymentrequest_0_amt    "89.90"
paymentrequest_0_itemamt    "71.02"
paymentrequest_0_taxamt "18.88"
paymentrequest_0_paymentaction  "Sale"
paymentrequest_0_name   "Sweaters van Superdry"
paymentrequest_0_qty    "2"

理想情况下，请求应该是这样的：

paymentrequest_0_itemamt=71.02
paymentrequest_0_taxamt=18.88
paymentrequest_0_amt=89.90


L_PAYMENTREQUEST_0_NAME0 = Sweaters van Superdry
L_PAYMENTREQUEST_0_AMT0= 35.51  
L_PAYMENTREQUEST_0_QTY0= 2

这导致了问题。

没有paymentrequest_0_qty参数。
