Tutorials on how PHP beginners can learn to implement WeChat payment and Alipay payment

伊谢尔伦Original: 2017-07-05 09:53:025678browse

The two most popular payment platforms at the moment, WeChat Pay and Alipay Payment, make payments very conveniently through mobile phone QR codes in streets, alleys, shopping malls, supermarkets, convenience stores, etc., reducing the use of cash.

Next, our PHP Chinese website will take PHP beginners to understand how to implement WeChat payment and Alipay payment.

The first thing you need is to have a certain grasp and understanding of PHP knowledge. You can learn through tutorials:

You can also learn the popular tp5 framework course in China first:

WeChat payment

Project premise: use It is a tp framework, PHP language
Download the WeChat payment interface file provided by the WeChat platform, put it in the tp third-party class library vendor, and name it 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. The source code has been partially modified

(1) WxPay.Api. Comment out
in php //require_once "WxPay.Exception.php";
//require_once "WxPay.Config.php";
//require_once "WxPay.Data.php ";

(2) In WxPay.Config.php
it is necessary to configure APPID, MCHID, KEY and APPSECRET according to the merchant information.

(3) Comment out
in WxPay.Data.php //require_once "WxPay.Config.php";
//require_once "WxPay.Exception.php";

(4) Comment out
in WxPay.JsApiPay.php //require_once "../lib/WxPay.Api.php";

Configure these. Next is our focus.

2. In the order controller GoodsController.class.php, there are the order function sure() and the 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 = &#39;O&#39; . date(&#39;YmdHis&#39;) . $o_model->get_order_code(4);
    while ($o_model->findone(array("order_code" => $order_code))) {
     $order_code = &#39;O&#39; . date(&#39;YmdHis&#39;) . $o_model->get_order_code(4);
    }
    $data[&#39;order_code&#39;] = $order_code;
    $addr[0] = $_POST[&#39;prov&#39;];
    $addr[1] = $_POST[&#39;city&#39;];
    $addr[2] = $_POST[&#39;dist&#39;];
    $addr[3] = $_POST[&#39;area&#39;];
    $data[&#39;area&#39;] = serialize($addr);
    $data[&#39;create_time&#39;] = time();
    $data[&#39;update_time&#39;] = time();
 
    if ($data[&#39;pay_id&#39;] == 1) {
     $data[&#39;order_status&#39;] = 11; //已付款
     $data[&#39;status&#39;] = &#39;1&#39;;
    } else {
     $data[&#39;order_status&#39;] = 10; //待付款
     $data[&#39;status&#39;] = &#39;1&#39;;
    }
    //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 (&#39;4&#39; == $data[&#39;pay_id&#39;]) {
   if (&#39;4&#39; == $data[&#39;pay_id&#39;]) {
   //微信支付
   $msg = &#39;正在为您跳转到微信支付页面，请等待……&#39;;
   $url = "/index.php/wine/wxpay/index/?o_id=$add_id";
  }
  $this->success("订单提交成功！" . $msg, $url);
 }

5. Jump to when payment is successful OrderController.class.php, order payment completed

/**

  $info = $this->model->findone(array("a.id" => $o_id, &#39;a.status&#39; => array(&#39;neq&#39;, &#39;-1&#39;)));
  if (empty($info)) {
   # 获取最新可用的商品编号
   $goods = D(&#39;Goods&#39;)->where(array(&#39;status&#39; => &#39;1&#39;))->order(&#39;id desc&#39;)->find();
   $this->error("该订单不存在，请重新正确进入", U(&#39;Goods/sale&#39;, array(&#39;id&#39; => $goods[&#39;id&#39;])));
  }
  $this->assign(&#39;imgurl&#39;, "/wine/img/ok.png");
  $this->assign(&#39;tips&#39;, "订购成功");
  if (&#39;4&#39; == $info[&#39;pay_id&#39;]) {
   //微信支付成功
   $this->assign($info);
   $this->display();
  } else {
   $this->assign($info);
   $this->assign(&#39;tips&#39;, "订购失败");
   $this->assign(&#39;imgurl&#39;, "/wine/img/nook.png");
   $this->display();
  }
 }

At this point, the WeChat payment process ends.

Alipay payment

Without further ado, let’s go straight to the code!

Note:
1. The payment file is taken directly from Alipay
2. It is still a TP framework

[1]Put the file into a third party Class library:

(1)
* Class name: AlipayConfig.php
* Function: AlipayConfiguration file
* Modify configuration:

 // MD5密钥，安全检验码，由数字和字母组成的32位字符串，查看地址：https://b.alipay.com/order/pidAndKey.htm
  $alipay_config[&#39;key&#39;] = &#39;&#39;;//（**从支付宝中获取**）
 
 // 服务器异步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问
  $alipay_config[&#39;notify_url&#39;] = &#39;http://&#39; . $_SERVER[&#39;SERVER_NAME&#39;] . &#39;/index.php/Wine/PayCallback/alipay_notify&#39;;
 
 // 页面跳转同步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问
  $alipay_config[&#39;return_url&#39;] = &#39;http://&#39; . $_SERVER[&#39;SERVER_NAME&#39;] . &#39;/index.php?g=Wine&m=Orders&a=alipay_return&#39;;

(2)
* Class name: AlipayNotify.php
* Function: Alipay notification processing class
* Details: Process Alipay interface notification returns

(3 )
* Class name: Alipay.php
* Function: Mobile website payment interface access page
* Details: Process Alipay interface notifications and return

class Alipay {
 
 public function submit($params) {
//建立请求
  $alipaySubmit = new AlipaySubmit($alipay_config);
  $html_text = $alipaySubmit->buildRequestForm($parameter, "get", "确认");
  return &#39;<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html>
  <head>
   <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
   <title>支付宝支付</title>
  </head>&#39; . $html_text . &#39;
  </body>
  </html>&#39;;
 }
}

(4)
* Class name: notify_url.php
* Function: Alipay server asynchronous notification page
* Details: Process Alipay interface notification returns

[2] Payment business logic
(1) Go to GoodsController.class.php and submit the order ajax_sure()

public function ajax_sure() {<br>
 $data[&#39;order_code&#39;] = $order_code;
 $addr[0] = $_POST[&#39;prov&#39;];
 $addr[1] = $_POST[&#39;city&#39;];
 $addr[2] = $_POST[&#39;dist&#39;];
 $addr[3] = $_POST[&#39;area&#39;];
 $data[&#39;area&#39;] = serialize($addr);
 $data[&#39;create_time&#39;] = time();
 $data[&#39;update_time&#39;] = time();
 $data[&#39;ip&#39;] = $_SERVER[&#39;REMOTE_ADDR&#39;];
 if ($data[&#39;pay_id&#39;] == 1) {
   $data[&#39;order_status&#39;] = 11; //已付款
   $data[&#39;status&#39;] = &#39;1&#39;;
 } else {
   $data[&#39;order_status&#39;] = 10; //待付款
   $data[&#39;status&#39;] = &#39;1&#39;;
 }
 //函数调用 返回信息
 $this->Callback_url($data);
}
/**
  * 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！");
  }<br>
  if (&#39;3&#39; == $data[&#39;pay_id&#39;]) {
   //支付宝支付
   $msg = &#39;正在为您跳转到支付宝支付页面，请等待……&#39;;
   $url = U("Pay/doalipay", array(&#39;o_id&#39; => $add_id));
  }
  $this->success("订单提交成功！" . $msg, $url);
 }

(2) PayController.class.php and go to

 /**
  * 支付页面
  */
 public function doalipay() {
  $o_id = I("get.o_id", 0, "intval");
  $info = $this->model->findone(array("a.id" => $o_id, &#39;a.status&#39; => array(&#39;neq&#39;, &#39;-1&#39;)));
  //10代表订单待支付的状态
  if ($info[&#39;order_status&#39;] != 10) {
   $this->error("订单已支付！");
  }
  vendor("Payment.Alipay.Alipay");
  $alipay = new \Alipay();
  $param[&#39;order_sn&#39;] = $info[&#39;order_code&#39;];
//  $param[&#39;order_amount&#39;] = $info[&#39;pay_price&#39;];
  $param[&#39;order_amount&#39;] = 0.01;//测试支付时，将支付价格设为0.01元，土豪朋友忽略此提示O(∩_∩)O~
  $param[&#39;order_subject&#39;] = &#39;支付宝支付测试&#39;;
  $param[&#39;return_url&#39;] = &#39;http://&#39; . $_SERVER[&#39;SERVER_NAME&#39;] . &#39;/index.php/Wine/Orders/pay_ok/o_id/&#39;.$o_id;
  $return = $alipay->submit($param);
  echo $return;
  exit;
 }

It’s just a few simple steps. At this point, Alipay The payment process is over.
