Dedecms integration with final payment interface _ php skills

This article mainly introduces dedecms's integration of relevant information on the payment interface of Tenpay. if you need it, you can refer to dedecms's travel website and ask the customer to pay for it, I searched for the Internet, either to buy or to ask for money. I only wrote it myself.

Code:

The code is as follows:

<? Php
If (! Defined ('deinc') exit ('request Error! ');
/**
* Caifu Tong interface
*/
Class tenpay
{
Var $ dsql;
Var $ mid;
Var $ reqURL_onLine = "http://www.tenpay.com ";
Var $ return_url = '/plus/carbuyaction. php? Dopost = return '; // return address
/**
* Constructor
*
* @ Access public
* @ Param
*
* @ Return void
*/
Function tenpay ()
{
Global $ dsql;
$ This-> dsql = $ dsql;
}

* Set the interface to send the address
*
* Example: $ this-> SetReturnUrl ($ cfg_basehost. "/tuangou/control/index. php? Ac = pay & orderid = ". $ p2_Order)
