我在一个网站上工作，我有一个自定义订单表格，在结帐时会显示一个 PayPal Express Checkout 按钮。该按钮使用销售价格和订单号正确重定向到 FireFox 中的 PayPal，但是在 Safari 和 Chrome 中，当我单击该按钮时，没有任何反应。使用 Chrome 开发人员工具，我可以看到当我单击按钮时正在处理 GET 请求，但随后立即取消。我已经尝试将表单目标更改为 target="_self" 和 target="paypal" 这没有帮助。这是我的 PayPal Express Checkout 按钮和重定向到 PayPal 的代码：
//////payment handlers
if ($payprovider == 'paypal') {
////hand off to paypal
header("Location: order-inspection.php?process=paypal&amount=".$row12['customer_payment_amount']."&items=".$row12['COUNT(session)']."&order=".$row12['ordernumber']." ");
} elseif ($payprovider == 'googlewallet') {
////hand off to google
header("Location: order-inspection.php?process=googlewallet&amount=".$row12['customer_payment_amount']."&items=".$row12['COUNT(session)']."&order=".$row12['ordernumber']." ");
} elseif ($payprovider == 'wepay') {
////hand off to google
header("Location: order-inspection.php?do=wepay&amount=".$row12['customer_payment_amount']."&items=".$row12['COUNT(session)']."&order=".$row12['ordernumber']." ");
} elseif ($payprovider == 'callin') {
////hand off to google
header("Location: order-inspection.php?do=callin&amount=".$row12['customer_payment_amount']."&order=".$row12['ordernumber']."&id=".$_SESSION['CURINSPECID']." ");
} else {
////send to step one because inspectid dropped
header("Location: order-inspection.php?do=step1&error=sessiondropped");}
} elseif (isset($_GET['process']) && $_GET['process'] == 'paypal') {
////vars needed
$orderamount = cleanget('amount');
$orderitems = cleanget('items');
$ordernumberid = cleanget('order');
////update payment provider
$SQL1 = " UPDATE inspections_payment SET customer_payment_status='Dropped at Paypal',payment_provider = 'paypal' WHERE ordernumber = '".$ordernumberid."'";
$result1 = mysql_query($SQL1,$cid)or die(mysql_error());
////print the image to let customer know they are being redirected
