## Description
Selytho Page Flip Creator renders your PDFs as a hardware-accelerated 3D flipbook
directly in the browser. No Flash, no external services, no server-side processing—
just upload a PDF, drop in a shortcode, and your visitors get a beautiful page-turning
experience instantly.
The engine is built on Three.js (WebGL) with PDF.js for client-side rendering. Pages
curl realistically with configurable curl amount and flip speed. The viewer is fully
responsive and works on desktop, tablet, and mobile.
**WebGL Rendering**
Smooth, hardware-accelerated page turns powered by Three.js. Cylindrical vertex
deformation gives each page a natural curl. Front and back faces are rendered as
separate meshes with correct UV mapping and depth ordering.
**PDF.js Powered**
PDF pages are rendered client-side by PDF.js — no server-side image conversion or
pre-processing required. Simply provide a PDF URL. All rendering happens in the
visitor’s browser.
**Flipbook Editor**
Each flipbook has its own settings page in the WordPress admin with a live preview
that updates as you change settings. Configure appearance, controls, info panel,
and Pro features all in one place.
**Info Panel**
Display PDF metadata — title, author, subject — in an elegant overlay panel. Override
any field per flipbook. Supports custom colours and an optional logo (Pro).
**Share Panel**
Built-in share overlay with social sharing links — Facebook, X (Twitter), LinkedIn,
Pinterest, BlueSky, and email — plus a one-click copy button for the page URL.
**Bookshelf Mode**
Group multiple PDFs into a single flipbook with a shelf selector. Each book in the
shelf has its own info panel overrides.
**View Statistics**
Track views, pages seen, and read depth per flipbook session. A dedicated Statistics
page shows all-time totals and a per-flipbook breakdown with inline bar charts.
**RTL Support**
Right-to-left page order is fully supported. Enable RTL per flipbook or as a global
default. All text inputs in the admin panel support bidirectional text entry.
**Viewer Settings Panel**
Visitors can adjust flip speed, curl amount, interaction mode, and pan direction
in real time from a settings panel in the controls bar — without reloading the page.

### Uninstall
Data removal is **opt-in**. By default, deleting the plugin preserves all your data
so it can be re-installed without loss. If you enable **Settings Delete data on
uninstall**, then deleting the plugin removes all plugin data from your WordPress
database, including:
* All view records (`slyth_views` table)
* All flipbook post meta (`_slyth_*` keys)
* All plugin settings and options prefixed with `slyth_`
* Licence key and validation data
The uninstall script does **not** delete:
* Your PDF files — these remain in the Media Library
* Any site content — posts, pages, users, WooCommerce data, etc.
### Disclaimer
Selytho Page Flip Creator is provided as-is, without warranty of any kind. Rob Snow/
Rob Art | WordPress Development accepts no responsibility or liability for data
loss or any damage arising from the use of this plugin. You are solely responsible
for ensuring your use of this plugin complies with applicable law in your jurisdiction.
PDF rendering is performed client-side by PDF.js. Rendering quality and performance
depend on the visitor’s device and browser. Very large PDFs may load slowly on low-
powered devices.
### External Services
Selytho Page Flip Creator does not connect to any external services during normal
operation. All PDF rendering is performed client-side in the visitor’s browser using
PDF.js. No visitor data or content is transmitted externally.
Licence validation communicates with the Rob Art licence server at `https://robsnow.
eu` solely to verify your Pro licence key. This only occurs when you activate or
deactivate a licence from the Settings page.

## Installation
1. Download the Selytho Page Flip Creator plugin zip file.
2. In your WordPress admin, go to **Plugins > Add New > Upload Plugin**.
3. Choose the downloaded zip file and click **Install Now**.
4. Once installed, click **Activate Plugin**.
5. The plugin will appear as **Selytho** in the WordPress admin sidebar. Click it
to open the dashboard.
Alternatively, install via FTP by uploading the `selytho-page-flip-creator` folder
to `/wp-content/plugins/` and activating from the Plugins screen.
On first activation you will be redirected to a getting started screen.
## FAQ
### Is Selytho Page Flip Creator free?
Yes. The core plugin is free and includes the WebGL viewer, flipbook editor, bookshelf
mode, info panel, share panel, view statistics, and all free controls. Pro features—
soft flip style, auto-flip, zoom, pan, fullscreen, thumbnails, sound, and advanced
controls — are available with a Pro licence.
### Does it require any server-side processing?
No. PDF pages are rendered entirely in the visitor’s browser by PDF.js. You simply
provide a URL to any publicly accessible PDF file.
### Will it work with any PDF?
Yes, as long as the PDF is publicly accessible via a URL. PDFs served with restrictive
CORS headers may fail to load — host the file on the same domain as your WordPress
site or ensure appropriate CORS headers are set.
### Does it work on mobile?
Yes. The viewer is fully responsive. Touch drag-to-flip is supported on mobile and
tablet.
### Can I embed multiple flipbooks on one page?
Yes. Each shortcode initialises its own independent viewer instance.
### Will it slow my site down?
Selytho only loads its scripts and styles on pages where the shortcode is present.
Three.js and PDF.js are served from your own server — no external CDN requests are
made.
### What happens to data when I deactivate the plugin?
Deactivating the plugin stops tracking but preserves all data. Data is only removed
when the plugin is deleted, and only if you have enabled **Settings Delete data
on uninstall** (off by default).

## Changelog
#### 1.3.15
* Updated the Pro upgrade link to the live checkout
#### 1.3.14
* Renamed the internal admin menu identifiers and the shortcode to use the plugin’s
unique “slyth” prefix, avoiding any possible clash with other plugins
* The shortcode is now [slyth_flipbook] (if you previously used the older tag,
update your embeds to [slyth_flipbook])
#### 1.3.13
* Soft page-curl is now provided entirely by the Pro add-on — the free build no
longer contains any disabled or restricted soft-curl code (full WordPress.org
trialware compliance)
* Control bar position, mode and distance are now available to everyone in the
free editor’s Controls panel
* Primary shortcode is now [slyth_flipbook]; the original [selytho] shortcode continues
to work, so existing embeds are unaffected
* Hardened input handling on the admin screens (all request reads are now explicitly
sanitised)
#### 1.3.12
* Updated the bundled 3D engine and PDF rendering libraries to their current releases(
resolves an out-of-date PDF library with a known security advisory)
* The info-panel logo is no longer part of the free build at all — the free viewer
shows the Selytho logo, and a custom brand logo is provided by the Pro add-on
* Fixed page rendering after the library updates: pages now display as crisp white
paper (no grey tint or soft text)
* Hardened the PDF viewer’s error handling so a page that fails to render no longer
stalls the rest of the book
* Raised page texture resolution for sharper text, with a lighter setting auto-
applied to very large documents to keep memory in check
#### 1.3.11
* Completed the output-escaping pass on the flipbook editor — the remaining conditional
style and numeric-bound attributes are now escaped at output. No change to behaviour
or appearance.
#### 1.3.10
* Hardened output escaping across the admin and viewer templates — every dynamic
value is now escaped at the point of output to meet WordPress.org review standards.
No change to behaviour or appearance.
#### 1.3.9
* Hardened output escaping on the editor’s Pro upgrade advert (logo and purchase
link) to satisfy WordPress.org review standards
* Raised the minimum WordPress version to 6.2, matching the secure identifier placeholder
used in the view-statistics queries
#### 1.3.8
* Fixed collections (multi-PDF bookshelves) failing to display with a “no PDF URL
provided” message — a shelf with one or more books now renders correctly
* Fixed the editor live preview overflowing its box when padding was increased —
the preview now scales to keep the whole viewer inside the frame
* Book tabs in the viewer’s info panel now switch the displayed book, not just
its information
* Added a reader keyboard and mouse shortcut reference to the editor’s Controls
help sidebar
* Tidied a stray product label so the branding reads “Selytho” consistently
#### 1.3.7
* Rebuilt the flipbook-editor “Pro Features” panel so the free build shows an upgrade
advert in its place — no disabled or locked feature controls are present without
the Pro add-on
* Completed the free/Pro split: all Pro feature defaults, saving, viewer output
and the per-flipbook sound picker are now supplied exclusively by the Pro add-
on, with the free build fully functional on its own
* Updated the bundled 3D engine library to a current maintained release
* Hardened the editor so it loads cleanly when the Pro add-on is not installed
#### 1.3.6
* Security hardening for WordPress.org compliance: the view-tracking endpoint now
verifies a request nonce, all view-statistics queries use fully prepared statements,
and admin sidebar output is escaped through an allowlist
* No change to viewer behaviour or statistics
#### 1.3.5
* Renamed the plugin to “Selytho Page Flip Creator” (removed the restricted “WP”
term from the name, slug and text domain) for WordPress.org compliance
* Added a “Get Pro” link to the plugins-list row (shown on the free tier only)
* Made the soft page-curl a true Pro-only feature: the free build no longer contains
any soft-cover rendering code, so soft is unavailable without the Pro add-on
* Removed the in-plugin Pro auto-installer and the licence-key entry from the free
build; the upgrade screen is now advert-only, and all licence activation/status
UI is supplied by the Pro add-on
* Rebuilt the Settings “Pro Features” card, the Soft flip-style option and the
Sound option so the free build shows an upsell only — no disabled or locked controls
* Fixed flipbooks rendering as a tall, letter-boxed sliver inside block themes (
constrained-layout width is now respected)
* Redesigned the upgrade overlay: clearer benefit bullets, a taller hero image,
and added points about custom logos and removing the Selytho branding
* The “Created with Selytho Page Flip Creator” credit now links to the product
page and reads consistently in the editor preview and on the front end
* Kept the plugin menu open with all items visible while editing a flipbook
* Removed unused bundled code (legacy viewer and the StPageFlip library) from the
package
#### 1.3.4
* Increased minimum width on select dropdowns to 110px so the selected option no
longer crowds the chevron arrow
#### 1.3.3
* Fixed native colour pickers (``) being squashed to a thin
line under WordPress 7.0 — restored to a proper 48×30 swatch
* Added a custom chevron arrow and right padding to select dropdowns so the arrow
no longer overlaps the option text under WordPress 7.0
#### 1.3.2
* Fixed Pro Features card “Upgrade” button and Licence card “Get Pro” button —
both now open the in-plugin upgrade modal instead of navigating away to robsnow.
eu
#### 1.3.1
* WordPress 7.0 compatibility — restored familiar form, button, checkbox and radio
styling that WP 7.0 changed

* Added per-flipbook Sound card — sample, select, or randomise from a pool of page-
turn sounds
* Added large document warning overlay with configurable page threshold (Settings
Performance)

PDFs

* Fixed large document overlay not showing in admin preview
* Fixed overlay re-appearing on refresh via sessionStorage confirmation
* Settings layout switched to CSS masonry columns
#### 1.2.8
* Fixed sound not firing on every page turn — sound engine now clones Audio nodes
per play so rapid flips never conflict
* Fixed same sound repeating consecutively — added no-repeat shuffle across the
sound pool
* Updated page-turn sound effects
* Fixed PDF metadata not loading on media library select — fetchPdfMeta no longer
triggers a redundant preview rebuild when called alongside loadPreview
#### 1.2.7
* Fixed delete flipbook causing “headers already sent” warning by moving handler
to admin_init
* Fixed Info Panel Branding card moved to top of column 3 in Settings layout

panel side swap
