Meeting Sign-in Application Development Guide for DingTalk Interface and PHP

With the popularization of the Internet and the advancement of technology, the method of meeting sign-in has gradually evolved from traditional paper sign-in to online sign-in. As a very popular enterprise communication tool, DingTalk’s powerful open interface function provides developers with many possibilities. This article will introduce how to use the DingTalk interface and PHP language to develop a conference check-in application, and provide some code examples for reference.

First of all, we need to understand DingTalk’s interface permissions and development process. Before starting development, we need to create a developer account on the DingTalk open platform and complete the account authentication. After the authentication is completed, we can apply for the corresponding application permissions and obtain an available access_token.

Next, we need to understand how to use the DingTalk interface. DingTalk provides a series of API interfaces to manage users, departments, group chats, meetings and other functions. In this development, we mainly focus on the user and conference interface.

As a scripting language widely used in Web development, PHP’s concise syntax and powerful processing capabilities make it the first choice for many developers. Let's take a look at how to use PHP to develop a DingTalk meeting sign-in application.

First, we need to write a PHP script to handle the logic of user check-in. After receiving the user's sign-in request, we can verify the user's identity and submit the sign-in information to the DingTalk interface.

<?php
// 获取钉钉access_token，具体的获取方法请参考钉钉开放平台文档
$access_token = '这里填写你的access_token';

// 获取用户信息，这里以获取用户的钉钉ID为例
$user_id = $_POST['dingtalk_user_id'];

// 获取会议ID
$meeting_id = $_POST['meeting_id'];

// 用户签到逻辑，这里以插入数据库为例
$db = new mysqli('localhost', 'username', 'password', 'database');
$sql = "INSERT INTO sign_in (user_id, meeting_id) VALUES ('$user_id', '$meeting_id')";
$result = $db->query($sql);
if ($result) {
    echo '签到成功';
} else {
    echo '签到失败';
}

In the above code, we first obtain the user's DingTalk ID and meeting ID through $_POST, and then insert this information into the database.

Next, we need to modify the check-in settings for the meeting to forward the request to our PHP script. We can use DingTalk’s custom bot feature to achieve this functionality.

First, we need to create a new custom robot and associate it with the corresponding conference group chat. Then, we can forward the user check-in request to our PHP script through the DingTalk robot's Webhook function. For specific setting methods, please refer to the DingTalk Open Platform documentation.

<?php
// 获取钉钉机器人Webhook地址
$webhook = '这里填写你的钉钉机器人Webhook地址';

// 构建请求参数
$data = array(
    'msgtype' => 'text',
    'text' => array(
        'content' => '签到请求',
    ),
);

// 发送请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $webhook);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

echo $response;

In the above code, we first construct a request parameter, then use the curl library to send the request, and output the response result to the page.

Through the above steps, we can implement a simple DingTalk meeting sign-in application. When a user sends a check-in request in the group chat, the DingTalk robot will forward the request to our PHP script, perform corresponding processing, and return the processing result to the user.

To sum up, this article introduces how to use the DingTalk interface and PHP language to develop a conference sign-in application. By understanding how to use the DingTalk interface and the basic syntax of PHP, we can implement a simple meeting sign-in system ourselves. Hope this article helps you!
