Shortcode Usage Basic: [o7_flipbook id="123"] All parameters: [o7_flipbook id="123" mode="flipbook" width="100%" height="600" orientation="auto" light="yes" zoom="yes" download="yes" autoplay="no" thumbs="yes" sound="yes" stealth="no" accent="#e53935" bg="#1a1a2e" toolbar="#ffffff" text="#222222" radius="8"] Large books with search: [o7_flipbook src="https://example.com/book.pdf" search="yes" search_url="https://example.com/search.json" page_param="page" lazy="yes"] Languages The admin interface language can be changed from Settings → O7 FlipBook → Interface Language. This changes all menu labels, meta box titles, viewer controls, and settings text. For WordPress .po/.mo file translations (e.g. via Loco Translate), a .pot template is included at languages/o7-flipbook.pot.

2.8.1

• Fix: books with thousands of pages froze after a search result or long page jump. The page-flip renderer re-wrote the inline style of every page on each animation frame (8,600 writes per frame on a large book), keeping the main thread busy and starving page rendering; hidden pages are now left untouched.
• Fix: thumbnails scrolled past during a long jump are no longer rendered; the thumbnail strip jumps instantly across long distances.

2.8.0

• New: in-book search. search="yes" adds a search bar above the viewer; results list the page and a highlighted snippet, the first hit opens right away and prev/next buttons step through the rest. Matched words are highlighted on the rendered page.
• New: search_url parameter for large documents: a JSON endpoint (GET ?q= → {total, results:[{page, snippet}], unavailable}) backed by a server-side text index. Without it the PDF text layer is searched in the browser.
• New: lazy mode for very large PDFs (lazy="auto" by default: files over 12 MB or more than 60 pages). Only the pages around the reader are rendered and far pages are released; PDF bytes are fetched by range, so books with thousands of pages open in seconds.
• New: start_page, page_param (keeps the current page in the address bar for shareable links), mobile_height and per-instance lang shortcode parameters.
• Search matching is case-, accent- and diacritic-insensitive (Turkish letters, Arabic harakat and letter variants).

2.7.2

• Renamed plugin display name to "O7 Interactive PDF FlipBook".
• Moved all inline / output to wp_add_inline_script() / wp_add_inline_style().

2.7.1

• New: magazine-style cover view — the flipbook now opens with the cover page centered on its own (no more blank white page next to it); two-page spreads begin from the second page, and the lone back page is centered the same way
• New: PDF Orientation setting (Auto Detect / Portrait / Landscape) — per FlipBook, as a global default in Settings, and as a shortcode parameter (orientation="landscape"). Landscape PDFs now get properly landscape grid tiles, thumbnails and slides instead of cropped portrait boxes. Available in all 8 interface languages.
• Fixed admin buttons: icons inside "Select PDF" / preview buttons are now vertically centered
• Faster, progressive rendering: the viewer now opens after the first pages render and finishes the rest in the background (large PDFs no longer freeze the tab)
• Page-turn sound now plays the moment a flip starts instead of ~0.7s later, and is limited to one sound per turn
• Fixed pagination control: the "/ N" total no longer wraps to a second line and the page-number input is no longer widened by host-theme input styles
• Fixed the Interface Language selector being vertically clipped on the settings screen
• Updated bundled Swiper to 14.0.6 (carousel mode); StPageFlip already on latest 2.0.7
• Carousel navigation arrows now match the flipbook arrows exactly (unified pill style; fixes oversized Swiper 14 SVG arrows)

2.7.0

• All third-party libraries (PDF.js, StPageFlip, Swiper) are now bundled with the plugin — no external CDN requests (WordPress.org guideline compliance)
• Security: strict validation of the width value used in generated CSS
• Security: hex color values re-validated at output time
• Removed unused AJAX scaffolding (admin-ajax URL and nonce are no longer exposed on the frontend)
• Added uninstall.php — plugin settings and FlipBook posts are cleaned up on delete
• Various escaping and input-unslashing improvements (WordPress coding standards)

2.6.4

• Added hover-reveal toolbar in normal (non-light) mode
• Carousel: reduced slide gap and scale difference
• Plugin description now translates based on selected language
• Added readme.txt and .pot template for WordPress.org / Loco Translate

2.6.3

• Toolbar: click-to-open, auto-close on mouse-leave
• Light/Paper theme: toolbar tab always readable (accent bg contrast fix)

2.6.2

• Added Zoom Controls toggle (per-post and global default)
• Carousel: hidden swiper pagination, removed slide box-shadows
• Loading screen text made more readable
• Toolbar tab label now translated via data-label attribute
