Description

PDF Blätterkatalog turns any PDF file into an interactive, browsable catalog directly on your WordPress site. Features include:

  • Double-page spread view with correct cover alignment (cover displayed alone, then proper left/right spreads)
  • Real-time search across table of contents and full PDF text content
  • Accordion table of contents with chapter navigation
  • Page flip animation for a realistic browsing experience
  • Zoom controls with fit-to-window
  • Fullscreen mode
  • Multiple catalogs via Custom Post Type – each with its own shortcode
  • Customizable colors (accent, background, text)
  • Lazy loading with HTTP Range Requests for fast initial page display

Installation

  1. Upload the pdf-katalog folder to /wp-content/plugins/.
  2. Download PDF.js v3.11.174 from https://mozilla.github.io/pdf.js/getting_started/#download and place pdf.min.js and pdf.worker.min.js into assets/lib/.
  3. Activate the plugin through the 'Plugins' menu in WordPress.
  4. Go to "PDF Kataloge" in the admin sidebar to create a new catalog.
  5. Upload your PDF and configure the table of contents (JSON format).
  6. Use the shortcode [pdf_katalog slug="your-slug"] on any page.

Frequently Asked Questions

How do I add a table of contents?

In the catalog editor, paste a JSON array in this format: [{"chapter":"Chapter Name","items":[{"title":"Section","page":6}]}]

Can I have multiple catalogs on one site?

Yes. Each catalog is a Custom Post Type entry with its own shortcode.

The catalog loads slowly – what can I do?

Make sure your server supports HTTP Range Requests (Apache/nginx do by default). The plugin uses lazy loading so only visible pages are fetched. For very large PDFs (100+ MB), consider optimizing the PDF file size first.
