README

QR codes in a Symfony application: in Twig, in an accessible component, at a cached address, in UJO documents and in PDF documents.

phil/qr-code-bundle brings phil/qr-code into Symfony. The configuration sets the defaults of every code — level of error correction, quiet zone, colours, size, ECI header, kanji, the longest payload — and the logos a template may name. qr_code() draws a text or a typed content in Twig as inline SVG or a data: URI; the component <twig:PhilQrCode:QrCode> puts the code in a figure with what it holds written beside it; a signed route serves codes as SVG or PNG with a long HTTP cache. The qrCode blocks of UJO (Universal JSON Output) documents are drawn with the same defaults for phil/svg-blocks-bundle, and PdfQrCodes draws codes in PDF documents of phil/paged-media, in vectors.

It is for any Symfony application that shows or prints QR codes: tickets, gift cards, posters, contact cards, Wi-Fi signs, pages and books. Every code is drawn on the server; nothing is sent to a service.

Quick start

composer require phil/qr-code-bundle

# config/packages/phil_qr_code.yaml
phil_qr_code:
    error_correction: Q
    logos:
        brand: { path: '%kernel.project_dir%/assets/logo.svg', zone: 0.2 }

{{ qr_code('https://example.com/tickets/42', {title: 'Ticket 42'}) }}
<twig:PhilQrCode:QrCode :content="{type: 'wifi', ssid: 'Gnome Café', password: 'tea-and-dice'}" logo="brand" />

Requirements

PHP 8.5 or later with ext-sodium, Symfony 8.2 or later, Twig 3.21 or later, and phil/qr-code. Three integrations are optional, suggested rather than required, and registered only when their package is installed: Symfony UX Twig Component for the component, phil/svg-blocks (or phil/svg-blocks-bundle) for the qrCode blocks of UJO documents, and phil/paged-media for QR codes in PDF documents. The bundle installs and passes its tests without them.
