问题描述
大家好，
我想在将字段数量发送到支付网关之前，将5.5％的费用添加到字段数量中。我可以在文本框中添加费用并显示。但我无法发送到支付网关..它说校验和错误。请帮忙！
工作版本这里
输入一个虚拟名称，虚拟电子邮件，虚拟电话，金额和点击提交..它将重新加载一次并进入支付网关的页面，这将显示校验和错误。
错误是字段金额。实际上Payu提供代码
Hi all,
I want to add 5.5% fees to the field amount before sending it to the payment gateway..I am able to add the fees and show in a text box. But I couldn't send to payment gateway..It says "Checksum error". Please help!
The working version is given here
Enter a dummy name, dummy email, dummy phone, amount and click submit.. It will reload once and take to payment gateway's page which will show checksum error.
The error is with the field "amount". Actually Payu provide the code
<input name="amount" value="<?php echo (empty($posted['amount'])) ? '' : $posted['amount'] ?>" />但我只想添加5.5％的金额。
But I just want to add 5.5% to that amount.

推荐答案
发布['amount']））？ ''：
posted['amount'])) ? '' :
已发布['金额']？> / >
posted['amount'] ?>" />
但我只想添加5.5％的金额。
But I just want to add 5.5% to that amount.
