最近，一个项目要求做交通银行在线支付，ecshop本身没有这方面的接口，于是通过一些时间的专研，做了一个插件出来。有好的东西，当然要分享，在此特地分享出来，希望能够帮助到跟我一样有需要的人，为大家减轻一下开发的负担，也多请大家指出一些好的方法和建议，相互的学习、进步！

在使用插件之前，请配置好交通银行在线支付的环境（具体安装方法，交行提供的demo会有，也不是很难，注意好细节就行）。安装好之后，请将把下面的插件源码和语言包源码按路径保存到相应文件，最后进入后台的支付模块安装即可。

语言包源码（languages/zh_cn/payment/bankcomm.php）:

复制代码代码如下:

<?php

/**

* 交通银行语言文件

* by: Reson

* 2014/03/31

global $_LANG;

$_LANG['bankcomm'] = '交通银行在线支付';

$_LANG['bankcomm_desc'] = '交通银行在线支付';

$_LANG['pay_button'] = '交通银行支付';

以下是调用的范例：

复制代码代码如下:

include_once(ROOT_PATH . 'includes/modules/payment/bankcomm.php');

$order_['orderid'] = $order['order_sn'];

$order_['amount'] = $order['yd_price'];

$order_['orderMono'] = '测试';//商家备注

$order_['goodsURL'] = "http://".$_SERVER['HTTP_HOST'].'/respond.php?code=bankcomm';//取货URL

$pay_code = new bankcomm;

$pay_button = $pay_code->get_code($order_);

$order['pay_button'] = $pay_button;//即此时已经生成了一个支付按钮
