Wiki

A wiki / knowledge-base extension for Flarum 2. Members write public articles with full edit history; every change is captured as an immutable revision.

Features

• Public articles. Anyone can read articles. Members with the permission can create them and edit collaboratively.
• Categories. Admin-configurable, each with name, slug, description, color, icon, and position. Articles can be filed under one category (or none).
• Revision history. Every save that changes an article's title or body records a revision — a snapshot of the title and content at that point, attributed to the editor. The history is read-only and viewable from the article page.
• Markdown content. Article bodies run through Flarum's formatter, so Markdown/BBCode and format extensions (mentions, emoji) work the same as in discussions. The rendered HTML is produced on demand at serialize time, so format extensions apply retroactively to older articles.
• Moderation. Editors can soft-delete and restore articles; soft-deleted articles stay visible to editors (with a "deleted" treatment) and hidden from everyone else. Permanent deletion is admin-only and requires the article to be soft-deleted first, then cascades to its revisions.
• File attachments. Optional integration with fof/upload.

Requirements

• Flarum 2.0.0+
• PHP 8.3+

Permissions

• linkrobins-wiki.createArticle — start new articles.
• linkrobins-wiki.editArticles — edit and moderate (soft-delete / restore) any article, not just one's own.

Authors can always edit their own articles. Admins bypass every check. Permanent deletion is admin-only.

Forum UI

• /wiki — the article list, with a category filter in the sidebar.
• /wiki/new — write a new article (title, optional category, body).
• /wiki/:id — the article page, with the rendered body, edit/moderation controls, and the revision history.
• /wiki/:id/edit — edit an existing article.

Admin UI

Settings live at admin → Extensions → Link Robins Wiki: full CRUD for article categories.

Data model

Three tables:

• linkrobins_wiki_categories — name, slug, description, color, icon, position.
• linkrobins_wiki_articles — category_id, user_id (author), last_edited_by_user_id, title, content (parsed-source), last_edited_at, deleted_at.
• linkrobins_wiki_revisions — article_id, user_id (editor), title, content, summary.
