ecshop交通银行在线支付插件使用例子

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includes文件夹和languages文件夹拷贝到ecshop站点的根目录覆盖（最下面有源码下载），最后进入后台的支付模块安装即可。

以下是调用的范例：

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
