Practical steps for implementing leave approval through Enterprise WeChat interface and PHP

With the continuous innovation of enterprise management methods in the new era, Enterprise WeChat has become a powerful tool for internal communication and collaboration within the enterprise. Among them, leave approval is one of the important links in the daily management of an enterprise. This article will introduce the practical steps on how to use the enterprise WeChat interface and PHP to implement leave approval, and provide code examples for reference.

1. Create an enterprise WeChat application
Before we start to implement leave approval, we need to create an enterprise WeChat application first. The specific steps are as follows:

1. Log in to the enterprise WeChat management backend and click "Application Management" in the left navigation bar.
2. On the "Application Management" page, click the "Create Application" button.
3. In the application creation page, fill in the application name, application logo and other basic information, and select the required permissions, such as approval, address book, etc.
4. After the creation is completed, obtain key information such as the application's AgentId, CorpId, and SecretKey, which will be used later.

2. Obtain access_token
Before using the enterprise WeChat interface, we need to obtain access_token first. access_token is the token used to call the enterprise WeChat interface and has a certain validity period. The code example for obtaining access_token is as follows:

function getAccessToken($corpid, $secret) {
    $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={$corpid}&corpsecret={$secret}";
    $result = file_get_contents($url);
    $resultObj = json_decode($result);

    if ($resultObj->errcode === 0) {
        return $resultObj->access_token;
    } else {
        // 处理获取access_token失败的情况
        return null;
    }
}

3. Create a leave approval template
Create a leave approval template in the enterprise WeChat management background. The specific steps are as follows:

1. Log in to the enterprise WeChat management backend and click "Approval" in the left navigation bar.
2. On the "Approval" page, click the "Add Approval Template" button.
3. According to actual needs, fill in the basic information of the approval template, such as name, filler, carbon copy person, etc.
4. According to the specific content of the leave, add corresponding form controls, such as leave type, reason for leave, etc.
5. After the creation is completed, obtain the template_id of the leave template. This value will be used later.

4. Initiate a leave application
The following is an example of using PHP code to call the enterprise WeChat interface to initiate a leave application:

function submitLeaveApplication($access_token, $template_id, $data) {
    $url = "https://qyapi.weixin.qq.com/cgi-bin/oa/applyevent?access_token={$access_token}";
    $postData = array(
        "template_id" => $template_id,
        "use_template_approver" => 1,
        "approver" => array(
            array("attr" => 1, "userid" => "approver1"),
            array("attr" => 2, "userid" => "approver2")
        ),
        "notifyer" => array("notifyer1", "notifyer2"),
        "apply_data" => array(
            array("control" => "Text", "id" => "请假类型", "value" => $data["leave_type"]),
            array("control" => "Text", "id" => "请假事由", "value" => $data["reason"]),
            // 添加其他请假控件的值
        )
    );
    $postDataJson = json_encode($postData);
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postDataJson);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $result = curl_exec($ch);
    curl_close($ch);

    $resultObj = json_decode($result);
    
    if ($resultObj->errcode === 0) {
        return true;
    } else {
        // 处理发起请假申请失败的情况
        return false;
    }
}

In the above code, submitLeaveApplication The $data parameter in the method is an associative array that stores leave-related information.

Through the above steps, we can implement the leave approval process in corporate WeChat. When an employee initiates a leave application, the system will automatically send a notification to the approver. The approver can perform the approval operation in the enterprise WeChat application, and the applicant can also check the progress of the leave approval at any time.

Note: In actual implementation, you may also need to connect to the enterprise WeChat address book interface to obtain employee information, and process callback notifications of approval results, etc.

Summary
This article introduces the practical steps on how to use the enterprise WeChat interface and PHP to implement leave approval. Through the above steps, we can flexibly handle the leave process within the company. Of course, there may be other requirements and details in specific business scenarios, which need to be adjusted and expanded accordingly according to the actual situation. I hope this article can help you understand and apply the enterprise WeChat interface.
