Practical steps for implementing administrative approval through the Enterprise WeChat interface and PHP

Enterprise WeChat is a communication tool specially created for enterprises. It not only provides the function of internal corporate communication, but also supports the internal administrative approval process of the enterprise. . This article will introduce how to use PHP combined with the enterprise WeChat interface to implement the administrative approval function, and attach corresponding code examples.

Step one: Obtain the permissions of the enterprise WeChat interface

Before starting the implementation, we first need to obtain the permissions of the enterprise WeChat interface. Log in to the management side of Enterprise WeChat and follow the document guidelines to activate the corresponding interface permissions, including permissions to approve applications. After obtaining the interface permission, you can obtain the CorpID, Secret, AgentID and other information of the enterprise WeChat.

Step 2: Generate AccessToken

Before using the enterprise WeChat interface, you need to generate an AccessToken for verification of interface calls. We can use the following PHP code to generate:

<?php

$corpId = 'your_corp_id';
$secret = 'your_secret';

$accessTokenUrl = 'https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid='.$corpId.'&corpsecret='.$secret;
$result = file_get_contents($accessTokenUrl);
$accessToken = json_decode($result)->access_token;

echo $accessToken;

?>

Replace 'your_corp_id' and 'your_secret' in the above code with your own CorpID and Secret, and get the generated AccessToken by accessing the PHP file.

Step 3: Create an approval template

Create an approval template on the management side of Enterprise WeChat. The template needs to contain information such as each node of the approval process, approving personnel, form fields, etc. After the approval template is created, the corresponding template_id will be obtained for subsequent interface calls.

Step 4: Submit an approval application

Use the following PHP code example to submit an approval application:

<?php

$accessToken = 'your_access_token';
$url = 'https://qyapi.weixin.qq.com/cgi-bin/oa/applyevent?access_token='.$accessToken;

$data = array(
    'creator_userid' => 'your_user_id',
    'template_id' => 'your_template_id',
    'use_template_approver' => true,
    'apply_data' => array(
        array('key' => 'field1', 'value' => 'value1'),
        array('key' => 'field2', 'value' => 'value2'),
        // ...
    )
);

$options = array(
    'http' => array(
        'header' => "Content-type: application/json
",
        'method' => 'POST',
        'content' => json_encode($data),
    )
);

$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);

echo $result;

?>

Replace 'your_access_token', 'your_user_id' in the above code and 'your_template_id' are replaced with the corresponding values, where 'your_user_id' is the ID of the user who submitted the approval, and 'your_template_id' is the ID of the approval template created earlier.

Step 5: Get the approval progress and results

Use the following PHP code example to get the progress and results of an approval:

<?php

$accessToken = 'your_access_token';
$url = 'https://qyapi.weixin.qq.com/cgi-bin/oa/getapprovaldetail?access_token='.$accessToken;

$data = array(
    'sp_no' => 'your_sp_no',
    'info_type' => 1
);

$options = array(
    'http' => array(
        'header' => "Content-type: application/json
",
        'method' => 'POST',
        'content' => json_encode($data),
    )
);

$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);

echo $result;

?>

Change 'your_access_token in the above code ' and 'your_sp_no' are replaced with the corresponding values, where 'your_sp_no' is the approval number of the approval application.

The above are the practical steps for using the enterprise WeChat interface combined with PHP to implement administrative approval. Through the above steps, we can implement the functions of submitting approval applications and obtaining approval progress and results. In practical applications, function expansion and optimization can also be carried out according to specific needs.
