如何在 moodle 的特定课程中注册用户

Question

我需要你的帮助来在测验完成的基础上为特定课程注册用户 我需要做的是当学生完成学生已经注册的课程页面上的特定测验时，我想向按钮显示我已经成功地显示了下一个按钮，当用户单击该按钮时，用户会看到一个弹出式消息，他会得到“你呢”想在提交时继续下一门课程我希望用户自动注册该课程

我现在做了什么请检查 在课程 view.php 文件中，我添加了这段代码

global $USER;

$quiz_id = 1; // Replace 35 with the ID of the quiz you want to check
$user_id = $USER->id; // Replace $USER with the Moodle global user object if you're not inside a function that has $USER as a parameter

$attempts = quiz_get_user_attempts($quiz_id, $user_id);

if (!empty($attempts)) {
    $completed = false;
    foreach ($attempts as $attempt) {
        if ($attempt->state == quiz_attempt::FINISHED) {
            // Quiz has been completed by the user
            $completed = true;
            break;
        }
    }
    if ($completed) {
        echo '<button id="enroll-button">Click me</button>';
    } else {
        echo "Quiz has not been completed by the user.";
    }
} else {
    // No attempt exists for the given user and quiz
    echo "No attempt exists for the given user and quiz.";
}
?>

<script type="text/javascript"> 
 $(document).ready(function() { 
    // Code to display the enroll button goes here
    $('#enroll-button').click(function() {
        var confirmPopup = confirm("Do you want to enroll in all courses?");
        if (confirmPopup == true) {
            // Code to enroll the user in all courses goes here
            var userId = <?php echo $USER->id; ?>;
            var roleId = 5; // Add the ID of the role you want to enroll the user in
            var courseIds = ['3']; // Add the ID of the course you want to enroll them in
            // Enroll the user in each course
            $.each(courseIds, function(index, courseId) {
                // Call the PHP script that enrolls the user in the course
                $.ajax({
                    type: "POST",
                    url: "/dacold/course/enroll_user.php",
                    data: {
                        userId: userId,
                        roleId: roleId,
                        instanceid: 0,
                        enrolperiod: 0,
                        courseId: courseId
                    },
                    success: function(data) {
                        console.log("User enrolled in course ID: " + courseId);
                    },
                    error: function(jqXHR, textStatus, errorThrown) {
                        console.log("Error enrolling user in course ID: " + courseId);
                    }
                });
            });
        } else {
            // Code to handle cancel button click goes here
            alert("You have chosen not to enroll in all courses.");
        }
    });
});
