PHP實現的交通銀行網銀線上支付介面ECSHOP外掛程式和使用例子_php執行個體

最近，一個項目要求做交通銀行線上支付，ecshop本身沒有這方面的介面，於是通過一些時間的專研，做了一個外掛程式出來。有好的東西，當然要分享，在此特地分享出來，希望能夠協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！


在使用外掛程式之前，請配置好交通銀行線上支付的環境（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，請將把下面的外掛程式源碼和語言套件源碼按路徑儲存到相應檔案，最後進入背景支付模組安裝即可。

外掛程式源碼（includes/modules/payment/bankcomm.php）:

語言套件源碼（languages/zh_cn/payment/bankcomm.php）:

複製代碼 代碼如下:

<?php

/**
 * 交通銀行語言檔案
 * by: Reson
 * 2014/03/31
 */

global $_LANG;

$_LANG['bankcomm'] = '交通銀行線上支付';
$_LANG['bankcomm_desc'] = '交通銀行線上支付';
$_LANG['pay_button'] = '交通銀行支付';

?>

以下是調用的範例：

複製代碼 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'; //商家備忘
$order_['goodsURL'] = "http://".$_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; //即此時已經產生了一個支付按鈕
