Frequently Asked Questions

Does this plugin work with WooCommerce?

Zeko Learn is designed as a standalone LMS. It integrates with the Zeko ecosystem of plugins but works independently.

Can I use this without Zeko Pay?

Yes. Free courses can be created without any payment plugin. For paid courses, the plugin builds a checkout redirect URL that can integrate with any payment system.

How do students access courses?

Students enroll via the course page, then access lessons through the course player at /courses/{course-slug}/learn/.

Can I issue certificates?

Yes. Certificates are automatically issued when a student completes all lessons in a course. Certificates have unique numbers that can be verified publicly.

Is there a REST API?

Yes. A full REST API is available at /wp-json/zeko-learn/v1/. See the API documentation in the plugin files.

External Services

Zeko Learn can embed third-party video players when a course author adds an external video URL to a lesson. Everything is optional and off by default.

• YouTube (no-cookie mode) — When a lesson uses a YouTube URL and embeds are enabled, the video is loaded from www.youtube-nocookie.com/embed/{id} by default (so YouTube receives no cookies from your visitors). What is sent: the embed request itself; YouTube's own tracking/privacy policies apply. When: only when an author adds a YouTube URL and embedding is enabled.
• Vimeo — When a lesson uses a Vimeo URL and embeds are enabled, the video loads from player.vimeo.com/video/{id}. What is sent: the embed request itself. When: only when an author adds a Vimeo URL and embedding is enabled.

Embedding can be turned off entirely (admin setting Disable video embeds), in which case external video URLs never load third-party players; only https URLs are rendered and a hard allow-list of video hosts is enforced. Endpoint and data-field detail (with file:line citations) is in REMOTE-SERVICES.txt in this plugin folder.

Third-party resources

Zeko Learn bundles one third-party JavaScript asset: the html2pdf.js bundle (MIT) at assets/vendor/html2pdf/html2pdf.bundle.min.js, used for certificate PDF export (templates/certificate.php). The bundle also contains html2canvas and jsPDF (both MIT). Copyright (c) 2021 Erik Koopmans, (c) 2018 Dynamic Artists LLC, (c) 2016 Niklas von Hertzen, (c) 2010 James Hall. Full license text is in THIRD-PARTY-NOTICES.txt in this plugin folder (the bundle's own html2pdf.bundle.min.js.LICENSE.txt ships alongside it). MIT is GPL-2.0-or-later-compatible. All other assets are original Zeko work; Zeko Learn makes no server-side outbound requests.

Dependencies

Zeko Learn works standalone. It integrates with the Zeko ecosystem (dashboard tabs, activity feed, Zeko Pay for paid courses) but none of those plugins are required.

Privacy

Data stored includes student enrollments, lesson progress, quiz attempts, assignment submissions (including uploaded files), certificates, reviews, discussions, and course bookmarks. Video lessons may load from YouTube/Vimeo as described in External Services, which can send your IP to those providers.

Uninstall

Deleting the plugin drops all Zeko Learn tables (courses, sections, lessons, quizzes, attempts, assignments, certificates, and related data) and removes its options. Course content you created outside the plugin is not affected.

Troubleshooting

• Course not appearing? Confirm the course is published and the [zeko_learn_catalog] shortcode is on the page.
• Certificate not issued? A certificate is generated only when all required lessons are marked complete.
• Video won't play? Check the lesson URL is in the allowed video hosts; embedding can be disabled under Learn > Settings.
