做一個印尼的ecshop二次開發，需要開發一個印尼本地的第三方支付的插件。印尼本地最大的線上支付是日本公司開發的Veritrans，Veritrans網址爲：https://www.veritrans.co.id
以下是ecshop的完整代碼：
第一步：在includes/modules/payment下，新建一個veritrans.php
<?php

?>第二步：爲veritrans.php新建語言文件，在languages/en_us/payment下，新建veritrans.php

global $_LANG;
$_LANG['veritrans'] = 'Veritrans';
$_LANG['veritrans_desc'] = 'veritrans is the online payment for Indonesia eCommerce';
$_LANG['veritrans_client_key'] = 'client key';
$_LANG['veritrans_server_key'] = 'server key';
$_LANG['pay_button'] = 'Pay in Veritrans immediately';
?>第三步：將veritrans的demo中的證書cacert.pem上傳到ecshop的cert下，並改名爲veritrans.pem
以上三步就完成了veritrans支付的全過程。
