PHP development of WeChat applet: EasyWeChat realizes user check-in function

As a new application form, WeChat applet is developing rapidly and is widely used. The check-in function is a function that many companies and organizations often need to record users' check-in, check-out and other information. This article will introduce how to use PHP to develop WeChat applet and use EasyWeChat, a powerful PHP development toolkit, to realize the user check-in function.

First of all, we need to understand EasyWeChat. EasyWeChat is a simple and powerful WeChat development toolkit that can help us quickly develop WeChat applets. It provides rich interfaces and functions, including user authorization, template messages, payment, etc. Here, we will use EasyWeChat to implement the user check-in function.

Here are some sample codes to help you get started quickly.

1. First, we need to configure developer options in EasyWeChat. You can refer to EasyWeChat's documentation to learn how to configure it.

use EasyWeChatFactory;

$options = [
    'app_id' => 'your-app-id',
    'secret' => 'your-secret',
    'token' => 'your-token',
    'response_type' => 'array',
];

$app = Factory::miniProgram($options);

2. Next, we need to get the user’s openid. In the development of small programs, each user has a unique openid used to identify the user. We can obtain the user's openid through the API of the mini program.

$user = $app->auth->session('code');

$openid = $user['openid'];

3. Now, we can start to implement the user check-in function. First, we need to create a database table to store user punch-in records.

CREATE TABLE `clock_in` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `openid` varchar(128) NOT NULL,
  `date` date NOT NULL,
  `time` time NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

4. Then, we can write an interface to receive the user's check-in request and store the check-in record into the database.

public function clockIn()
{
    $openid = $_POST['openid'];
    $date = date('Y-m-d');
    $time = date('H:i:s');

    // 将打卡记录插入数据库
    $result = DB::table('clock_in')->insert([
        'openid' => $openid,
        'date' => $date,
        'time' => $time,
    ]);

    if($result) {
        return response()->json([
            'status' => 1,
            'message' => '打卡成功！'
        ]);
    } else {
        return response()->json([
            'status' => 0,
            'message' => '打卡失败，请重试！'
        ]);
    }
}

5. Finally, we can call this interface in the front-end page of the mini program to implement the user's check-in function.

wx.request({
    url: 'http://your-domain.com/clockIn',
    method: 'POST',
    data: {
        openid: 'your-openid',
    },
    success: function(res) {
        if (res.data.status == 1) {
            wx.showToast({
                title: '打卡成功！',
                icon: 'success',
            });
        } else {
            wx.showToast({
                title: '打卡失败，请重试！',
                icon: 'none',
            });
        }
    }
});

Through the above sample code, we can see that it is very simple to use the EasyWeChat framework to implement the user check-in function of the WeChat applet. With just a few lines of code, we can complete the recording and storage of user punch-ins, and return appropriate prompt information to the user.

Summary: This article introduces how to use PHP to develop WeChat applet and use EasyWeChat to implement the user check-in function. Through code examples, we demonstrated the process from obtaining the user's openid to creating a database table and writing a check-in interface, and explained the idea of ​​​​implementing the check-in function. I believe that by understanding and applying the content described in this article, readers can quickly write a WeChat mini program check-in function that suits their own needs.
