PHP access to the letter sweep Code Payment Summary (summary) _php example

There are two modes of micro-credit-sweep-code payment,

Model one is more complex and requires the public number configuration callback address.

Mode two is easier, just configure the callback address in your code.

I'm using mode two this time.

Requires configuration parameters,

Const APPID = ' xxx ';
Const MCHID = ' xxx ';
Const KEY = ' xxx ';
Const Appsecret = ' xxx ';

Configure the Appid,appsecret of the public number. As well as micro-letter payment of Mchid and key.

Generate two-dimensional code, this page needs to beautify itself, not like Alipay as a result of its own.

Require_once "./phpcms/plugin/weixinpay/lib/wxpay.api.php";
Require_once "./phpcms/plugin/weixinpay/example/wxpay.nativepay.php";
Require_once './phpcms/plugin/weixinpay/example/log.php ';
$input = new Wxpayunifiedorder (); $input->setbody (' reservation '. $product _info[' name '). '
Order "); $input->setattach (' reservation '. $product _info[' name '). '
Order ");
$input->setout_trade_no ($order _info[' OrderNo '));
$input->settotal_fee ($order _info[' payprice '] * 100);
$input->settime_start (Date ("Ymdhis"));
$input->settime_expire (Date ("Ymdhis", Time () + 600));
$input->setgoods_tag (""); $input->setnotify_url ("http://www.ayuanduanzu.com/wxpay/notify.php");
The address is accessible by the extranet and cannot contain parameters $input->settrade_type ("NATIVE");
$input->setproduct_id ($product _info[' id '));
$notify = new Nativepay ();
$result = $notify->getpayurl ($input);
$code _url = $result ["Code_url"]; 

The callback address here is very fastidious, after the success of the sweep code payment, the micro-letter will automatically call this address. This address cannot contain any arguments, otherwise the call fails. I can't see a thing!

When a micro-trust is invoked, a parameter of the XML type is passed.

Check whether the payment has been paid, the payment completed, the order data processing.

Everything here is asynchronous, the two-dimensional code page can not see anything.

You can only obtain order status asynchronously to determine if the operation is successful.

Detect if payment succeeded
$ (document). Ready (function () {
setinterval ("Ajaxstatus ()", 3000); 

function Ajaxstatus () {
var OrderNo = $ ("#out_trade_no"). Val ();
if (OrderNo!= 0) {
$.ajax ({
URL: "? m=home&c=order&a=ajax",
type: "Get",
DataType: "JSON",
data: {
TODO: ' Ajaxcheckwxpay ',
Orderno:orderno,
},
success:function (JSON) {
if ( Json.status = = 1) {//Order status of 1 indicates successful payment
layer.msg (' pay success ', {icon:1,time:2000},function () {
window.location.href = "m=home&c=order&a=paydone&orderno=" +json.info[' OrderNo '];
Window.location.href = "Wxscansuccessurl.action"; Page Jump
}}}
);
}

Three seconds to execute once, if successful, jump processing.

Gift function

* Function: Array to XML
/function Arraytoxml ($arr)
$xml = "<xml>";
foreach ($arr as $key => $val)
{
if (is_numeric ($val))
{
$xml. = "<". $key. " > ". $val." </". $key." > "; 
}
else

* Function: Convert XML to array
/function Xmltoarray ($xml)
{ 
//convert XML to array 
$array _data = Json_decode ( Json_encode (simplexml_load_string ($xml, ' simplexmlelement ', Libxml_nocdata)), true); 
return $array _data;
}

Gift Tips

For an asynchronous call, if the effect is not visible. You can build a log table that records the operation's data in the table. Easy to test. The payment callback is asynchronous and can be judged by the data in the log table to determine whether the payment was successful, whether the callback was invoked, and how many times it was invoked.

Summary:

Micro-letter sweep code payment is not as easy as paying treasure sweep code payment. Need to do a lot of processing yourself.

The above is a small set to introduce the PHP micro-Scan Code Payment Access Summary (summary), the database shows the perfect solution blank (picture and text tutorial), I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone.
