How to use PHP to develop the task archiving function of WeChat applet?

WeChat Mini Program is a very popular mobile application development platform. Many developers hope to add a task archiving function to the Mini Program to record and manage completed tasks. This article will introduce how to use PHP to develop the task archiving function of WeChat applet and provide specific code examples.

First, we need to create a new mini program in WeChat Developer Tools and obtain the AppID and AppSecret of the mini program. This information will be used in subsequent development processes.

Next, we need to use the official interface provided by WeChat in PHP to implement the task archiving function. The specific steps are as follows:

1. Introduce the SDK of WeChat applet
   Since the development of WeChat applet requires the use of the SDK provided by WeChat, we need to introduce the SDK in PHP. You can install the PHP SDK of the WeChat applet through Composer, as shown below:

composer require overtrue/wechat-mini-program

2. Create a WeChat applet instance
   In the PHP code, we need to use the obtained AppID and AppSecret To create an instance of the WeChat applet, as shown below:

use EasyWeChatFactory;

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

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

3. Get access_token
   Next, we need to obtain the access_token by calling the API of the WeChat applet. access_token is the credential for accessing the WeChat applet interface, which can be obtained through the following code:

$response = $app->access_token->getToken();
$access_token = $response['access_token'];

4. Creating an archive task
   Before creating an archive task, we need to define a task object, including Information such as the title, content, and completion time of the task. The task object can be defined using PHP's associative array, as shown below:

$task = [
    'title' => '任务标题',
    'content' => '任务内容',
    'completed_at' => time(),
];

Next, we can create a new archiving task by calling the data storage interface of the WeChat applet, as shown below:

$response = $app->content_security->checkText($task['content']);
if ($response['errcode'] === 0) {
    $res = $app->db->collection('tasks')->add($task);
    // 归档任务创建成功
} else {
    // 任务内容包含违规内容，创建失败
}

In the code, we first called the content security interface of the WeChat applet to check whether the task content contains illegal content. If no violations are included, we save the task to the database. Otherwise, we will return an error message and the task creation fails.

5. Query archive tasks
   In addition to creating archive tasks, we can also query archive tasks by calling the data storage interface of the WeChat applet. You can use the following code to get all archived tasks:

$tasks = $app->db->collection('tasks')->where('completed_at', '<>', null)->get();

In the code, we used the where method to filter all completed tasks, and then called the get method to get all the qualified tasks. Task collection.

The above are the detailed steps for using PHP to develop the task archiving function of WeChat applet. By introducing the WeChat applet SDK, creating a WeChat applet instance, obtaining access_token, and creating and querying archiving tasks, we can implement a complete task archiving function.
