How to use PHP to implement the user tag management function of public accounts

How to use PHP to implement the user tag management function of public accounts requires specific code examples

In the development of public accounts, the user tag management function is a very important one Function. Through tag management, we can easily classify and manage users and achieve more accurate user targeted push. This article will introduce how to use PHP language to implement the user tag management function of public accounts and provide relevant code examples.

1. Obtain the access_token of the public account

Before using the interface of the WeChat public platform, you first need to obtain the access_token of the public account. Access_token is an important credential for public accounts to call interfaces and has a certain validity period. The code example for obtaining access_token is as follows:

<?php
$appid = 'your_appid';
$secret = 'your_secret';
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={$appid}&secret={$secret}";

$response = file_get_contents($url);
$result = json_decode($response, true);

$access_token = $result['access_token'];
?>

2. Create user tags

To create user tags in the official account, you can use the official account tag management interface. The code example for creating user tags is as follows:

<?php
$tag_name = '标签名称';

$url = "https://api.weixin.qq.com/cgi-bin/tags/create?access_token={$access_token}";
$data = [
    'tag' => [
        'name' => $tag_name
    ]
];

$options = [
    'http' => [
        'method' => 'POST',
        'header' => 'Content-type:application/json',
        'content' => json_encode($data)
    ]
];
$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);

$result = json_decode($response, true);
$tag_id = $result['tag']['id'];
?>

3. Obtaining user list

Obtaining user list is one of the basic operations of user tag management. You can use the official account user management interface to obtain the user list. The code example for obtaining the user list is as follows:

<?php
$next_openid = '';  // 第一次获取可不传

$url = "https://api.weixin.qq.com/cgi-bin/user/get?access_token={$access_token}&next_openid={$next_openid}";

$response = file_get_contents($url);
$result = json_decode($response, true);
$user_list = $result['data']['openid'];
?>

4. Tag users

After obtaining the user list, you can use the official account user tag management interface to tag the users. The code example for tagging users is as follows:

<?php
$openid = '用户openid';
$tagid = '标签id';

$url = "https://api.weixin.qq.com/cgi-bin/tags/members/batchtagging?access_token={$access_token}";
$data = [
    'openid_list' => [$openid],
    'tagid' => $tagid
];

$options = [
    'http' => [
        'method' => 'POST',
        'header' => 'Content-type:application/json',
        'content' => json_encode($data)
    ]
];
$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);

$result = json_decode($response, true);
?>

5. Obtaining the user tag list

To obtain the user tag list, you can use the official account tag management interface. The code example for obtaining the user tag list is as follows:

<?php
$url = "https://api.weixin.qq.com/cgi-bin/tags/get?access_token={$access_token}";

$response = file_get_contents($url);
$result = json_decode($response, true);
$tag_list = $result['tags'];
?>

Through the above steps, we can realize the user tag management function of the official account. Of course, the above code is for reference only, and the specific business logic and implementation methods need to be adjusted according to the actual needs of the official account.
