Supports PHP 8.2+ and Symfony 6.4 / 7.x / 8.x

Features

• Support 3 two-dimensional (2D) and 30 one-dimensional (1D) Barcode types
• Three output formats: HTML, PNG and SVG
• Twig integration: use the barcode function directly in your templates

Installation

composer require yellowskies/qr-code-bundle

The bundle uses Symfony Flex and will be automatically configured.

Manual registration (if not using Flex)

Add to config/bundles.php:

return [
    // ...
    Skies\QRcodeBundle\SkiesQRcodeBundle::class => ['all' => true],
];

Usage

Generate options

Default width/height: 2D = 5x5, 1D = 2x30 Default color: html/svg = "black", png = [0, 0, 0]

In Twig templates

{# HTML barcode #}
{{ barcode({code: 'Hello World', type: 'qrcode', format: 'html'}) }}

{# SVG with custom size and color #}
{{ barcode({code: 'Hello World', type: 'qrcode', format: 'svg', width: 10, height: 10, color: 'green'}) }}

{# PNG (base64 encoded) #}
<img src="data:image/png;base64,{{ barcode({code: 'Hello World', type: 'datamatrix', format: 'png'}) }}" />

In a controller/service

use Skies\QRcodeBundle\Generator\Generator;

class MyController extends AbstractController
{
    public function index(Generator $generator): Response
    {
        $barcode = $generator->generate([
            'code'   => 'Hello World',
            'type'   => 'qrcode',
            'format' => 'svg',
            'width'  => 10,
            'height' => 10,
            'color'  => 'green',
        ]);

        return new Response($barcode);
    }
}

Standalone usage

use Skies\QRcodeBundle\Generator\Generator;

$generator = new Generator();
$barcode = $generator->generate([
    'code'   => 'Hello World',
    'type'   => 'qrcode',
    'format' => 'html',
]);

Save to file

// HTML or SVG
file_put_contents('/tmp/barcode.svg', $barcode);

// PNG (decode base64 first)
file_put_contents('/tmp/barcode.png', base64_decode($barcode));

1. Update your composer.json to require "yellowskies/qr-code-bundle": "^2.0"
