OpenGraph Fallback Embed

Apraksts

OpenGraph Fallback Embed adds a custom Gutenberg block and an auto-embed fallback that renders rich link cards using OpenGraph metadata from any URL.

Features:

  • OpenGraph Embed block — Paste any URL to embed it as a styled card showing the page’s title, description, image, and site name.
  • Auto-embed fallback — When WordPress can’t find an oEmbed provider for a URL pasted on its own line, this plugin automatically fetches the page’s OpenGraph tags and renders a card instead of a plain link.
  • Graceful degradation — Falls back to Twitter Card meta tags, then to HTML <title> and <meta name="description"> when OpenGraph tags are missing.
  • Transient caching — Fetched metadata is cached for 7 days to minimise external requests.

Development

The source code for this plugin, including unminified JavaScript and CSS, is available on GitHub:

BUJ

What happens if a URL has no OpenGraph tags?

The plugin falls back to Twitter Card meta tags, then to the page’s <title> and <meta name="description">. If none of these are available, the original WordPress output is preserved.

Does this override existing embed providers?

No. This plugin only activates when WordPress has no other embed handler for the URL.

Can I customise the card appearance?

The card uses the .og-fallback-embed CSS class. You can override styles in your theme.
