在作业批准后，LearnDash Auto完成了主题

Question

因此，我已经在WordPress中创建了一个ED-Tech网站，并使用了LearnDash LMS系统，但是我想做一些事情，例如，教师批准了作业，因此它将自动完成该主题并显示完整的标记，目前在批准分配学生后批准了该主题单击“单击并继续”按钮后，需要完成该分配主题。

我还创建了一个函数并在此处附加代码。

代码从这里开始：

add_action('acf/save_post', 'assignment_custom_acf_save', 5);

function assignment_custom_acf_save($post_id) {

    if (get_post_type($post_id) == 'sfwd-assignment') {
        $prev_value = get_field('custom_approval_status', $post_id);
        $current_values = $_POST['acf'];        
        $new_status = $current_values['field_628fdf0a73412'];
        $assignment = get_post($post_id);
        $assignment_data = get_post_meta($assignment->ID);

        $student_id = $assignment->post_author;
        $course_id = $assignment_data['course_id'][0];
        $course_title = get_post_field('post_title', $assignment_data['course_id'][0]);
        $lesson_id = $assignment_data['lesson_id'][0];
        $lesson_title = $assignment_data['lesson_title'][0];
        $teachers_comment = $current_values['field_628fdef373411'];

        if ($new_status == 1) {
            delete_post_meta($post_id, 'approval_status');
            learndash_process_mark_incomplete($student_id, $course_id, $lesson_id);
            send_email_after_assignment_rejection($post_id, $teachers_comment);
            
            $rejection_message = 'Thanks for your submission for <b><a href="' . get_permalink($lesson_id) . '">' . $lesson_title . '</a></b> in the ' .
                '<b><a href="' . get_permalink($course_id) . '">' . $course_title . '</a></b>.<br><br>' .
                'Unfortunately, it didn\'t meet the requirements for this assignment.<br>' .
                (empty($teachers_comment) ? '' : 'This is the comment to your work: <b>' . $teachers_comment . '</b>') .
                '<br><br>Let\'s give it another go!';

            send_new_message($student_id, $rejection_message);
        } else if ($new_status == 2) {
            update_post_meta($post_id, 'approval_status', 1);
            learndash_process_mark_complete(I am not sure what should I put here because I am not able to create a topic id);
            send_email_after_assignment_approval($post_id, $teachers_comment);
            
            $approval_message = 'Great job on your assignment! <br><b>' . $teachers_comment . '</b>' . (empty($teachers_comment) ? '' : '<br>') .
                'Your submission for <b><a href="' . get_permalink($lesson_id) . '">' . $lesson_title . '</a></b> in the ' .
                '<b><a href="' . get_permalink($course_id) . '">' . $course_title . '</a></b> is now approved. <br>Thanks for spending the time to get that in.';

            send_new_message($student_id, $approval_message);
            
        }
    }
}

您需要两个函数来构建您的代码：

Learndash_is_assignment_approved_by_meta（检查是否批准了评估）
https://developers.learndash.com/function/learndash_is_assignment_approved_by_meta/

LearnDash_process_mark_complete（Automark完成）
https://developers.learndash.com/function/learndash_process_mark_complete/

That's an example of an我写的自动完成功能，也许可以帮助更好地了解其工作原理。

function ld_automark_complete()
{
    global $post, $current_user;
    
    $included_courses = array(
        30215,
         1107, 
        43013, 
        60082, 
        27081, 
        26025, 
        27180, 
        27341, 
        27200, 
 
    );

    $course_id = learndash_get_course_id();

    if (empty($course_id) || !in_array($course_id, $included_courses))
        return;
    
    if (! empty($current_user->ID) && ! empty($post->post_type) && $post->post_type == 'sfwd-lessons') {
        learndash_process_mark_complete($current_user->ID, $post->ID);
    }
    if (! empty($current_user->ID) && ! empty($post->post_type) && $post->post_type == 'sfwd-topic') {
        learndash_process_mark_complete($current_user->ID, $post->ID);
    }
}

add_action('wp', 'ld_automark_complete');
