PHP-implemented ECSHOP plug-in and example-PHP Tutorial

PHP implements the ECSHOP plug-in and use example for the Bank of Communications online banking payment interface. Recently, a project called for online payment by Bank of Communications. ecshop itself does not have this interface, so it developed a plug-in through some time research. There are good things, of course, recently, a project requires online payment by Bank of Communications. ecshop itself does not have this interface, so it has made a plug-in through some time research. If there are good things to share, I would like to share them here, hoping to help people who have the same needs as me and relieve the development burden for everyone, please also point out some good methods and suggestions for mutual learning and progress!


Before using the plug-in, configure the online payment environment of the Bank of Communications. (for the installation method, the demo provided by the Bank of Communications is not very difficult. just pay attention to the details ). After the installation is complete, save the following plug-in source code and language pack source code to the corresponding file in the path, and finally install the payment module in the background.

Plug-in source code (includes/modules/payment/bankcomm. php ):

The code is as follows:

Language Pack source code (ages/zh_cn/payment/bankcomm. php ):

The code is as follows:

/**
* Bank of Communications language files
* By: Reson
*
*/

Global $ _ LANG;

$ _ LANG ['bankcomm '] = 'Bank of communications online payment ';
$ _ LANG ['bankcomm _ desc'] = 'Bank of communications online payment ';
$ _ LANG ['pay _ click'] = 'Bank of communications payby ';

?>

The following is an example of a call:

The code is as follows:

Include_once (ROOT_PATH. 'includes/modules/payment/bankcomm. php ');
$ Order _ ['orderid'] = $ order ['Order _ sn '];
$ Order _ ['amount '] = $ order ['yd _ price'];
$ Order _ ['ordermono'] = 'test'; // merchant remarks
$ Order _ ['goodsurl'] = "http: //". $ _ SERVER ['http _ host']. '/respond. php? Code = bankcomm '; // pick up URL
$ Pay_code = new bankcomm;
$ Pay_button = $ pay_code-> get_code ($ order _);
$ Order ['pay _ click'] = $ pay_button; // A payment button is generated.

Bytes. There are good things, of course...
