How to use PHP to implement the forwarding and reporting function of WeChat mini program

With the continuous development of mobile Internet, WeChat mini programs have become the development focus of more and more enterprises. WeChat mini programs not only have the advantages of WeChat official accounts, APPs and other products, but also have the advantages of low development costs and wide promotion channels. Among them, the forwarding function of WeChat applet is one of the very important functions. This article will share how to use PHP to implement the forwarding and reporting function of WeChat mini program.

1. What is WeChat Mini Program Forwarding and Reporting

The forwarding function of WeChat Mini Program means that when users use the Mini Program, they can share certain information in the Mini Program to their circle of friends, etc. Social platforms, thereby increasing the exposure and dissemination of mini programs. The forwarding and reporting function is a data statistics function for the forwarding behavior of WeChat mini programs. It can record the user's forwarding behavior, including which social platform to forward to, the forwarding time and other information, thereby helping developers better understand user behavior. Optimize mini program promotion strategies and content.

2. Implementation process of forwarding and reporting by WeChat Mini Program

Before implementing the forwarding and reporting function of WeChat Mini Program, you need to first understand the forwarding mechanism and forwarding events of WeChat Mini Program.

1. WeChat applet forwarding mechanism

The forwarding of WeChat applet is implemented through the onShareAppMessage method in WeChat JS-SDK. When the user clicks the forward button in the mini program, the wx.onShareAppMessage method will be triggered. Developers can use this method to customize the forwarded title, content, pictures and other information.

2. WeChat Mini Program Forwarding Event

Sharing events in WeChat Mini Program mainly include the following two types:

onShareAppMessage: Event triggered when the user clicks the forward button in the upper right corner .

onShareTimeline: Event triggered when the user clicks on the upper right corner to share to Moments.

After understanding the forwarding mechanism and forwarding events of the WeChat applet, we can start to implement the forwarding and reporting function of the WeChat applet. Below we use PHP to write a simple forwarding reporting code.

3. Implementation of forwarding and reporting code for WeChat mini program

Before implementing the forwarding and reporting function of WeChat mini program, we need to use WeChat JS-SDK in the mini program for authorization and initialization. This step can be performed by referring to WeChat official documentation or related tutorials, so I won’t go into details here. After authorization and initialization are completed, we can write the forwarding reporting code.

The following is a code example for PHP to implement the forwarding and reporting function of the WeChat applet:

//获取微信分享数据
$shareData = json_decode(file_get_contents("php://input"), true);
//获取用户信息等相关数据
$userData = array(
    "openid" => "xxxx",
    "nickname" => "xxx",
    "avatar" => "xxx",
    //其它用户信息
);
//获取转发数据
$shareType = ""; //转发类型，如朋友圈、微信群等
$shareTime = ""; //转发时间
//存储转发数据
$db = new mysqli("localhost", "user", "password", "database");
$sql = "INSERT INTO share_record(openid, nickname, avatar, share_type, share_time) VALUES('%s', '%s', '%s', '%s', '%s')";
$sql = sprintf($sql, $userData["openid"], $userData["nickname"], $userData["avatar"], $shareType, $shareTime);
$db->query($sql);
$db->close();

?>

In the above code, We used the json_decode function in PHP to obtain WeChat sharing data, and obtained user information and other related data through the custom $userData array. Then, the forwarding data is obtained through some methods and stored in the database.

It should be noted that the above code is only a sample code, and the specific implementation method needs to be determined according to the specific situation. For example, you can choose to use databases such as MySQL and MongoDB to store and forward data, or you can use log files, caches, etc. to store data.

4. Summary

This article introduces how to use PHP to implement the forwarding and reporting function of the WeChat applet. The implementation process includes the authorization, initialization, forwarding mechanism and forwarding events of the WeChat applet, as well as the implementation Code writing and selection of specific implementation methods. I hope this article will be helpful to developers who are developing WeChat mini programs and have this need.
