QRotto – QR Code Generator

QRotto adds a “QR code” block and a [qrotto] shortcode. Pick a type, fill in the fields, and the code appears in your post as a sharp SVG image.

Four types

• Link (URL). Adds https:// if you leave it out.
• This page’s link. The code always points to the page it sits on.
• WiFi network. Guests scan and join. Special characters in the network name or password are escaped correctly, and hidden networks are supported.
• Contact card (vCard 3.0). Name, company, phone, email and website.
• Plain text. Anything up to the size one code can hold.

Scan check in the editor

While you edit, each code shows its grid size and the smallest width it should be printed at, never below 20 mm (0.8 in). Dense codes get a warning before you print a hundred copies. Visitors never see this.

Print cards for your counter or tables

Tools → QR Print Cards makes a sheet of cards ready to print and cut: guest WiFi with the network and password written underneath, a “Scan for our menu” sign, a review link or your contact card. Choose 1, 2, 4 or 8 cards on A4 or US Letter. The page warns you if the code would be printed too small to scan.

Static and private

• Codes are made on your own server. The plugin contacts no outside service, loads nothing from a CDN and tracks nothing.
• Codes are static: the content is inside the code itself, so they keep working as long as the content does. No redirects, no expiry, no account.
• Visitors load no JavaScript, only one small stylesheet.

Documentation

Every type and format is explained, with decoded examples, at qrotto.com/docs.

Third party code

The QR encoder is qrcode-generator by Kazuhiko Arase (MIT licence), bundled in includes/lib/. It was moved into its own PHP namespace; the changes are listed at the top of that file.
