README

A simple HTML widget for Flarum 2.0, built as a widget for fof/forum-widgets-core. Same skeleton as linkrobins/shoutbox.

What it does

Adds one configurable HTML widget to the FoF Forum Widgets placement editor. Admin sets:

Title — optional, shown above the body
Icon — FontAwesome class (e.g. fas fa-bullhorn)
HTML body — rendered as HTML, sanitised before display

Drag and place it from the FoF Forum Widgets admin page like any other widget.

Settings

Configured in Admin → Extensions → Link Robins HTML Widget, then placed from the FoF Forum Widgets page.

Setting	Required	What it does
Title	no	Shown above the body. Leave blank for a widget with no header.
Icon class	no	A FontAwesome class rendered beside the title, e.g. `fas fa-bullhorn`. Leave blank for no icon.
HTML body	yes	Raw HTML, sanitised before display (see the security note below).
Background color	no	The widget's background. Leave blank to follow your theme, which is what keeps it looking native in both light and dark mode.

How a change reaches readers

The body is not baked into the forum's boot payload. It is fetched from its own endpoint on demand, and only a short hash of the current settings rides along in the payload.

That hash is what makes an edit show up: changing any setting changes the hash, which changes the fetch URL, so a normal page reload picks up the new content. Readers do not need a hard refresh, and unchanged content still caches normally rather than being re-fetched on every page view.

What it does NOT do

One widget per forum, not a list of them. For several blocks of content, place several different widgets.
No per-tag or per-page targeting — placement is whatever FoF Forum Widgets gives it.
No Markdown. If you would rather write Markdown than HTML, use linkrobins/markdown-widget instead.

Requirements

Flarum 2.0 or later
fof/forum-widgets-core installed and enabled

The HTML sanitiser (DOMPurify) is bundled into the extension — nothing is fetched from a CDN at runtime.

Installation

composer require linkrobins/html-widget
php flarum cache:clear

In Flarum admin → Extensions, find Link Robins HTML Widget under the Forum Widgets category and enable it. Configure title/icon/body, then go to FoF Forum Widgets settings and place it where you want it.

Security note

The HTML body is passed through DOMPurify before display, so <script> tags, event-handler attributes, javascript: URLs, and unsafe elements such as <iframe> are stripped. The body is still admin-only — treat it like any other admin-controlled content.
