PHP development of WeChat payment and Alipay payment examples-PHP Tutorial-php.cn

This article mainly shares with you PHP development of WeChat payment and Alipay payment examples. There is no explanation about the payment process. You can search on the PHP Chinese website by yourself.

##WeChat payment

项目前提：本人用的是tp框架，PHP语言下载到微信平台提供的微信支付接口文件，放在了tp第三方类库vendor，命名为WxpayAPI，

WxpayAPI/lib/WxPay.Api.php 接口访问类;
WxpayAPI/lib/WxPay.Config.php 配置账号信息;
WxpayAPI/lib/WxPay.Data.php 数据对象基础类;
WxpayAPI/lib/WxPay.Exception.php 微信支付API异常类;
WxpayAPI/lib/WxPay.Notify.php 回调基础类
WxpayAPI/example/WxPay.JsApiPay.php JSAPI支付实现类

1. Partially modified the source code

（1）WxPay.Api.php 里注释掉
        //require_once "WxPay.Exception.php";
        //require_once "WxPay.Config.php";
        //require_once "WxPay.Data.php";
 
（2）WxPay.Config.php里
        需要根据商户信息对APPID ， MCHID ，KEY ， APPSECRET 进行配置。
 
（3）WxPay.Data.php 里注释掉
        //require_once "WxPay.Config.php";
        //require_once "WxPay.Exception.php";
 
（4）WxPay.JsApiPay.php 里注释掉
        //require_once "../lib/WxPay.Api.php";

After configuring these, the next step is our focus. .

2. In the order controller GoodsController.class.php there are order function sure() and callback information function Callback_url()

/**
* 提交订单函数
*/
public function sure() {
       $o_model = D("Wine/Orders");
 
       if (IS_AJAX) {
           $data = I("post.");
           if ($o_model->create($data)) {
 
               if (!sp_check_verify_code()) {
                   $this->error("验证码错误！");
               }
 
               #生成随机订单号
               $order_code = 'O' . date('YmdHis') . $o_model->get_order_code(4);
               while ($o_model->findone(array("order_code" => $order_code))) {
                   $order_code = 'O' . date('YmdHis') . $o_model->get_order_code(4);
               }
               $data['order_code'] = $order_code;
               $addr[0] = $_POST['prov'];
               $addr[1] = $_POST['city'];
               $addr[2] = $_POST['dist'];
               $addr[3] = $_POST['area'];
               $data['area'] = serialize($addr);
               $data['create_time'] = time();
               $data['update_time'] = time();
 
               if ($data['pay_id'] == 1) {
                   $data['order_status'] = 11; //已付款
                   $data['status'] = '1';
               } else {
                   $data['order_status'] = 10; //待付款
                   $data['status'] = '1';
               }
               //函数调用 返回信息
               $this->Callback_url($data);
           } else {
               $this->error($o_model->getError());
           }
       } else {
           $this->error($o_model->getError());
       }
   }
 
    /**
    * 回调信息函数
    * @param type $data

   public function Callback_url($data) {
       $o_model = D("Wine/Orders");
       $add_id = $o_model->add($data);
       if (!$add_id) {
           $this->error("订单提交失败，请稍后重试！");
       }
     if ('4' == $data['pay_id']) {

4. Front-end WeChat payment page wxpay.html

微信订单支付

订单已生成

该笔订单支付金额为： echo $pay_price;

立即支付

5. The payment successfully jumps to OrderController.class.php, and the order payment is completed

At this point, the WeChat payment process ends.

Not much to say, just direct Get on the code!

注：1.支付文件是从支付宝上直接拿过来的2.依旧是TP框架
