Diploma

Added

• Lesson content field layout. Lessons now have a proper Craft field layout, designed under Diploma → Settings → Lesson Content Fields. Add rich text/CKEditor, Assets (embedded PDFs, video, images), Matrix, link fields — anything Craft supports — so a single lesson can hold mixed rich content. The fields render on every lesson's edit screen and are available on the lesson element in your templates.
• "Select all that apply" question type. A new Multiple Response question type extends multiple choice to allow more than one correct answer. It's graded all-or-nothing: full marks only when every correct option is selected and no incorrect ones. Mark multiple answers correct in the quiz builder as usual; on the front end, render the options as checkboxes named responses[<questionId>][answerIds][].
• Plugin events. Diploma now fires its own events so integrations can react to learner activity: Enrollments::EVENT_AFTER_ENROLL, Enrollments::EVENT_AFTER_COMPLETE_COURSE, ProgressTracker::EVENT_AFTER_COMPLETE_LESSON, QuizGrader::EVENT_AFTER_GRADE_ATTEMPT (check $event->attempt->passed for a pass), and Certificates::EVENT_AFTER_ISSUE_CERTIFICATE. Event classes live in the justinholtweb\diploma\events namespace.
• Activity / audit log. An append-only audit trail of enrollments, lesson completions, quiz pass/fail (with score), course completions, and certificate issuance — recording who, when, and from which IP address. View and filter it under Diploma → Activity Log, export it as CSV for compliance and record-keeping, or read a user's history in templates with craft.diploma.getUserActivity(user). Entries keep a denormalised snapshot and use nullable references, so the audit trail survives deletion of the related course, user, or enrollment. Available in both editions.
• New permission: View activity log.

Changed

• Bumped schemaVersion to 1.1.0. Run php craft migrate/all after upgrading to create the diploma_activity_log table.

Added

• Optional front-end URLs for courses. Enable Course URLs under Diploma > Settings (or set enableCourseUrls, courseUriFormat, and courseTemplate in config/diploma.php) to give published courses their own routable URLs and a course.url. A slug field appears on the course edit screen when enabled. Courses saved before enabling it need to be re-saved from the control panel to generate their slug and URI.

Fixed

• Front-end template tags (craft.diploma.*) and the diploma* Twig filters could silently fail to register. The CraftVariable::EVENT_INIT listener and the Twig extension were being registered inside the deferred Craft::$app->onInit() callback, which can run after the craft template variable has already initialized. They're now registered directly in Plugin::init() so the variable and filters are always available in front-end templates.

Added

• Full multisite support. Each course, lesson, and quiz lives only on the site it was created on, just like Craft entries with site-scoped sections. Element queries and index pages are now correctly scoped to the active site.
• Standard Craft breadcrumb-style site switcher on every Diploma CP page (dashboard, course/lesson/quiz edit screens, enrollments, certificates, settings). Course and quiz element indexes show the same switcher when multisite is enabled. Switching sites preserves the current path and query params.
• Migration m260518_140000_pin_elements_to_primary_site cleans up any cross-site elements_sites rows from earlier installs so existing elements remain pinned to their original site.

Fixed

• "Add Question" button now appears on the quiz edit screen — the control-panel JS bundle was registering CSS only, so quiz-builder.js never loaded.
• Question modal is now scrollable when content exceeds the viewport; the Save/Cancel footer stays pinned while the body scrolls.
• Saving a question now works on multisite installs. The save endpoint URL was built by concatenating Craft.actionUrl + '/diploma/questions/save', which produced a broken URL when Craft.actionUrl already contained a ?site=… query string. Switched to Craft.getActionUrl() so the path is appended before the query string.
• Frontend progress.js and quiz.js no longer hardcode /diploma/api/… paths, which broke on sites configured under a non-root base URL. The asset bundle now publishes a window.DiplomaUrls object built from UrlHelper::actionUrl() so the scripts always hit the correct per-site action endpoint.

Changed

• Redesigned the question modal to use Craft's native form styling (proper field labels, select dropdown, fullwidth textareas, bordered answer rows) and Garnish's modal shell.
• Course, Lesson, and Quiz now declare isLocalized() as true and override getSupportedSites() to return only the element's own site, so each element is pinned to the site it was created on. New elements pick up the active site from Cp::requestedSite() so creating one with ?site=X writes it to that site.
• Bumped schemaVersion to 1.0.1. Run php craft migrate/all after upgrading.

Fixed

• Dashboard cards and other CP styles weren't loading because the plugin layout never registered the CP asset bundle.

Changed

• Marked nullable parameters explicitly (?string) on element defineSources() and defineActions() for forward compatibility with PHP 8.4's implicit-nullable deprecation.
• Switched lesson and course queries from the string form of orderBy() to the array form (['sortOrder' => SORT_ASC]), and quoted column references in select() so cross-driver behavior is consistent.

Added

• Initial release.
• Courses, lessons, and quizzes as Craft elements.
• Multiple question types: multiple choice, true/false, short answer, matching.
• Enrollment and progress tracking.
• Certificate generation with public verification.
• Pro edition: drip content, PDF certificates, Commerce/Headcount integration.
