Gutenberg block

Gutenberg QR code block for WordPress

QRCode Suite registers a native `qrcs/qr-code` Gutenberg block with inspector controls for choosing the QR, its size (64–1024 px) and its foreground and background colours. The editor canvas previews the real code as you adjust it, and the front end is rendered server-side through a `render_callback` — an inline SVG encoding the tracked `/q/{slug}` address.

The Gutenberg block is included on every plan, including Free.

Native block-editor block

Adds a `qrcs/qr-code` block under the Widgets category. Insert it from the block inserter — there is no shortcode syntax to remember.

Inspector controls

Sidebar panels for the QR picker (a REST-backed dropdown over `/qrcode-suite/v1/qrcodes`, plus a manual id field), a size slider from 64 px to 1024 px, and foreground / background colour pickers.

Live preview in the canvas

The editor renders the real code through the `/qrcode-suite/v1/blocks/qr-code/preview` endpoint, so size and colour changes are visible before you publish.

Server-side render

The block uses a `render_callback`, so the front-end markup is generated server-side: a `<figure class="wp-block-qrcs-qr-code">` wrapping an inline SVG. Nothing is fetched from an external image host at page load.

Alignment and anchors

Supports left, center, right, wide and full alignment plus an HTML anchor, so it behaves like a core block inside classic themes and block themes alike.

Tracked destination

The block encodes the QR's `/q/{slug}` address, so scans still route through the redirect engine and every embed follows a destination change made in the dashboard.
