最近，一個項目要求做交通銀行在線支付，ecshop本身沒有這方面的接口，於是通過一些時間的專研，做了一個插件出來。有好的東西，當然要分享，在此特地分享出來，希望能夠幫助到跟我一樣有需要的人，為大家減輕一下開發的負擔，也多請大家指出一些好的方法和建議，相互的學習、進步！
在使用插件之前，請配置好交通銀行在線支付的環境（具體安裝方法，交行提供的demo會有，也不是很難，注意好細節就行）。安裝好之後，請將把下面的插件源碼和語言包源碼按路徑保存到相應文件，最後進入後台的支付模塊安裝即可。

語言包源碼（languages/zh_cn/payment/bankcomm.php）:
復制代碼 代碼如下:
<?php
/**
* 交通銀行語言文件
* by: Reson
* 2014/03/31
*/
global $_LANG;
$_LANG['bankcomm'] = '交通銀行在線支付';
$_LANG['bankcomm_desc'] = '交通銀行在線支付';
$_LANG['pay_button'] = '交通銀行支付';
?>
以下是調用的范例：
復制代碼 代碼如下:
include_once(ROOT_PATH . 'includes/modules/payment/bankcomm.php');
$order_['orderid'] = $order['order_sn'];
$order_['amount'] = $order['yd_price'];
$order_['orderMono'] = '測試'; //商家備注
$order_['goodsURL'] = "http://".$_SERVER['HTTP_HOST'].'/respond.php?code=bankcomm'; //取貨URL
$pay_code = new bankcomm;
$pay_button = $pay_code->get_code($order_);
$order['pay_button'] = $pay_button; //即此時已經生成了一個支付按鈕
