Good afternoon, I am developing my own plugin (folder: local) for the Moodle platform version "2023042400" - (4.2.2+) on the Windows platform.

下午好，我正在为Windows平台上的Moodle平台版本“2023042400”-(4.2.2+)开发我自己的插件(文件夹：Local)。

There was such a need to subscribe to the event of the standard module "quiz" called "Send everything and finish". I have a need to get all the wrong answers after completing the test and give out additional information in the interface, but for now I will be happy only to sign the data.

因此需要订阅名为“发送所有内容并完成”的标准模块“测验”事件。我需要在完成测试后得到所有错误的答案，并在界面上提供额外的信息，但目前我只会高兴地签署数据。

The programming language used is "PHP".

使用的编程语言是“PHP”。

P.S. I am new to this environment, so I will be happy to describe the solution in detail.

Path to file: \local\adaptive_quiz\version.php:

文件路径：\LOCAL\ADAPTIAL_QUZ\version.php：

<?php
defined('MOODLE_INTERNAL') || die();

$plugin->version  = 2023090900; //version of plugin
$plugin->requires = 2023042400; //version of moodle
$plugin->pluginname = 'Adaptive Quiz';
$plugin->component = 'local_adaptive_quiz';

I tried to do a lot of things that Chat GPT advised me to do:

我试着做了很多Chat GPT建议我做的事情：

• Study the CMS Moodle source code. I have studied. I realized that the CMS creates through, like, the single_button class after it finds this form in JS or the subscribe to event button, but I didn't understand how to subscribe to the event and get the data myself.


• Subscribe to the prepared event through the name of the method, nothing happened.


• Subscribe via $handlers, but he also didn't call the method.

I check the method through error_log, it is checked by me every time through the callback method - before_footer. Here before_footer works fine.

Path: \local\adaptive_quiz\lib.php:

路径：\LOCAL\ADAPTIAL_QUZ\lib.php：

code that checks the plugin for operability:

检查插件可操作性的代码：

<?php
 function local_adaptive_quiz_before_footer(){
    error_log('лог сработал');
    return \core\notification::add('Plugin Local adaptive quiz is worked! v8', 
            \core\output\notification::NOTIFY_SUCCESS);
 }

code with variable "$handlers":

带有变量“$Handler”的代码：

//code that checks the plugin for operability...

 function local_adaptive_quiz_after_submit($attemptid) {
    error_log('local_adaptive_quiz_after_submit worked');

    //Answer of users...
    $user_responses = "ответы пользователя";

    echo json_encode($user_responses);
}

$handlers = array(
    'quiz_attempt_submitted' => array(
        'handlerfile' => '\local\adaptive_quiz\lib.php',
        'handlerfunction' => 'local_adaptive_quiz_after_submit',
        'schedule' => 'instant',
    ),
);

The answer turned out to be quite simple. It was necessary to create using the following path \local\{name_your_plugin}\db\events.php, following code:

答案原来很简单。必须使用以下路径创建：\local\{name_Your_plugin}\db\events.php，代码如下：

 $observers = array(
    array(
        'eventname' =>'\mod_quiz\event\attempt_submitted', //name of event
        'includefile' => '\local\adaptive_quiz\classes\attempt_event_submitted_observer.php', //file containing the callback function
        'callback' =>'observe_one', //callback function
        'internal' => false
    ),
 );

And along the path (\local\adaptive_quiz\classes\attempt_event_submitted_observer.php) that we wrote create a callback function:

并沿着我们编写的路径(\local\adaptive_quiz\classes\attempt_event_submitted_observer.php)创建一个回调函数：

function observe_one($event) {
    echo '<h1>observe_one is worked</h1>';
}

The main thing is that you need to check the function through the student account. Otherwise the function does not work.

最重要的是，你需要通过学生账号来查看功能。否则，该函数不起作用。
