PHP WeChat development: How to implement user tag management

In the development of WeChat public accounts, user tag management is a very important function, which allows developers to better understand and manage their own users. This article will introduce how to use PHP to implement the WeChat user tag management function.

1. Obtain WeChat user openid

Before using the WeChat user tag management function, we first need to obtain the user's openid. In the development of WeChat public accounts, it is a common practice to obtain openid through user authorization. After the user authorization is completed, we can obtain the user openid through the following code:

$code = $_GET['code'];
$accessToken = getAccessToken();
$openid_res = file_get_contents("https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=APPSECRET&code={$code}&grant_type=authorization_code");
$openid_obj = json_decode($openid_res, true);
$openid = $openid_obj['openid'];

Among them, the getAccessToken() function is used to obtain the access_token of the official account.

2. Get the user tag list

Before getting the user tag list, we need to get all the tags first. The code to obtain the label list is as follows:

$accessToken = getAccessToken();
$url = "https://api.weixin.qq.com/cgi-bin/tags/get?access_token={$accessToken}";
$data = file_get_contents($url);
$tags = json_decode($data, true)['tags'];

After obtaining the label list, we can obtain the labels owned by the user through the following code:

$accessToken = getAccessToken();
$url = "https://api.weixin.qq.com/cgi-bin/tags/getidlist?access_token={$accessToken}";
$data = '{
    "openid":' . '"' . $openid . '"
}';
$tags_res = httpPost($url, $data);  //httpPost为自定义函数
$tags_obj = json_decode($tags_res, true);
$tagid_list = $tags_obj['tagid_list'];

Among them, the httpPost function is a custom function used to Implement HTTP POST requests.

3. Create user tags

If you need to create a new user tag, you can do so through the following code:

$accessToken = getAccessToken();
$url = "https://api.weixin.qq.com/cgi-bin/tags/create?access_token={$accessToken}";
$data = '{
    "tag" : {
        "name" : "新标签"
    }
}';
$res = httpPost($url, $data);  //httpPost为自定义函数
$newTag = json_decode($res, true)['tag'];
$tagid = $newTag['id'];

4. Tag and untag users

After obtaining the list of tags owned by the user, we can add multiple tags to the user, or cancel existing tags. The codes for labeling and canceling labels are as follows:

//为用户添加标签
$accessToken = getAccessToken();
$url = "https://api.weixin.qq.com/cgi-bin/tags/members/batchtagging?access_token={$accessToken}";
$data = '{
    "openid_list": ["' . $openid . '"],
    "tagid": ' . $tagid . '
}';
$res = httpPost($url, $data);  //httpPost为自定义函数

//为用户取消标签
$accessToken = getAccessToken();
$url = "https://api.weixin.qq.com/cgi-bin/tags/members/batchuntagging?access_token={$accessToken}";
$data = '{
    "openid_list": ["' . $openid . '"],
    "tagid": ' . $tagid . '
}';
$res = httpPost($url, $data);  //httpPost为自定义函数
