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()
/**

*/
public function sure() {
$o_model = D("Wine/Orders");
if (IS_AJAX) {

} else {

$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());
}
}
/**

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['key'] = '';//（**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['notify_url'] = 'http://' . $_SERVER['SERVER_NAME'] . '/index.php/Wine/PayCallback/alipay_notify'; // 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['return_url'] = 'http://' . $_SERVER['SERVER_NAME'] . '/index.php?g=Wine&m=Orders&a=alipay_return';

* Class name: AlipayNotify.php
* Function: Alipay notification processing class

(3 )

class Alipay {
public function submit($params) {
//建立请求
$alipaySubmit = new AlipaySubmit($alipay_config);
$html_text = $alipaySubmit->buildRequestForm($parameter, "get", "确认");

}
} (4)

[2] Payment business logic
(1) Go to GoodsController.class.php and submit the order ajax_sure()
public function ajax_sure() {<br>
$data['order_code'] = $order_code;
$addr[0] = $_POST['prov'];
$addr[1] = $_POST['city'];

$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);
}
/**

* @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 ('3' == $data['pay_id']) {
//支付宝支付
$msg = '正在为您跳转到支付宝支付页面，请等待……';
$url = U("Pay/doalipay", array('o_id' => $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" => $o_id, 'a.status' => array('neq', '-1')));
//10代表订单待支付的状态
if ($info['order_status'] != 10) {
$this->error("订单已支付！");
}
vendor("Payment.Alipay.Alipay");
$alipay = new \Alipay();
$param['order_sn'] = $info['order_code'];
// $param['order_amount'] = $info['pay_price'];
$param['order_amount'] = 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['order_subject'] = '支付宝支付测试';
$param['return_url'] = 'http://' . $_SERVER['SERVER_NAME'] . '/index.php/Wine/Orders/pay_ok/o_id/'.$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.
