PHP-implemented ECSHOP plug-in and use example for Bank of Communications online banking payment interface

This article mainly introduces the ECSHOP plug-in and use example for the online payment interface of Bank of Communications Network banking implemented by PHP. For more information, see Ecshop.

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. 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:
