PHP implementation of WeChat applet likes and sharing functions

With the continuous development and popularization of mobile Internet, WeChat mini programs have become a promotion method used by more and more companies and individuals. In mini programs, the like and share functions are two very important functions. This article will introduce how to use PHP to implement the like and share functions of WeChat applet.

1. Implementation of the like function of the mini program

First, we need to obtain the user’s openid. This can be achieved by using the API provided by WeChat applet, namely wx.login() and wx.getUserInfo(). For specific API documentation, please refer to WeChat official documentation.

After obtaining the user's openid, we can use PHP to implement the like function. We could store each article or post in a database with the number of likes as a field in the corresponding record. When the user clicks the like button, we can perform a 1 operation on the corresponding record's likes field by sending a request to the background, and then update the value to the database.

The following is a simple PHP implementation code:

        

         Copy after login
        
       

2. Mini program sharing function implementation

The sharing function of the mini program can be achieved by calling the API provided by the WeChat mini program. wx.showShareMenu() to achieve. For specific API documentation, please refer to WeChat official documentation. When the user clicks the share button, we can call the wx.showShareMenu() API on the front end to open the mini program's sharing interface. After the user clicks the share button, we can set the share count field of the corresponding record to 1 and then update that value to the database.

The following is a simple PHP implementation code:

        

         Copy after login
        
       

This article introduces how to use PHP to implement the like and share functions of WeChat applet. Of course, this is just the most basic implementation. In actual development, we need to make corresponding optimization and improvements based on specific business and needs.
