YellowskiesQRcodeBundle

WORKS WITH PHP >= 7.1 AND SYMFONY 4/ 5 / 6 AND Twig 2.x, _(*1)

, _(*2)

YellowskiesQRcodeBundle is a Symfony4/5/6 Barcode Generator Bundle., _(*3)

Features:, _(*4)

1. Support 3 two-dimensional (2D) and 30 one-dimensional (1D) Barcode types
2. Three output formats: HTML, PNG and SVG canvas
3. Twig integration: you can simply use a extensional function of Twig in the template to generate Barcode
4. Core of this bundle from this project tc-lib-barcode

Installation

Add YellowskiesQRcodeBundle by running the command:, _(*5)

$ php composer.phar require yellowskies/qr-code-bundle 

Or, add YellowskiesQRcodeBundle to your composer.json, then execute php composer.phar update, _(*6)

"require": {
        "yellowskies/qr-code-bundle": "1.2.10"
    }

Composer will install the bundle to your project's vendor/yellowskies directory., _(*7)

Then, Enable the bundle in the kernel:, _(*8)

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Skies\QRcodeBundle\SkiesQRcodeBundle(),
    );
}

Generate options

To generate one barcode, you have 5 options can be configured., _(*9)

Default width and height for 2D barcode are 5, 5, for 1D are 2, 30. Default color for html, svg is black, for png is array(0, 0, 0), _(*10)

Usage by service

The bundle registers one service: skies_barcode.generator which will allows you to generate barcode:, _(*11)

• output html

$options = array(
    'code'   => 'string to encode',
    'type'   => 'c128',
    'format' => 'html',
);

$barcode =
    $this->get('skies_barcode.generator')->generate($options);

return new Response($barcode);

• output svg

$options = array(
    'code'   => 'string to encode',
    'type'   => 'qrcode',
    'format' => 'svg',
    'width'  => 10,
    'height' => 10,
    'color'  => 'green',
);

$barcode =
    $this->get('skies_barcode.generator')->generate($options);

return new Response($barcode);

• output png

$options = array(
    'code'   => 'string to encode',
    'type'   => 'datamatrix',
    'format' => 'png',
    'width'  => 10,
    'height' => 10,
    'color'  => array(127, 127, 127),
);

$barcode =
    $this->get('skies_barcode.generator')->generate($options);

return new Response('<img src="data:image/png;base64,'.$barcode.'" />');

For format png, the generator return the based64 of png file, so you can get the real data of png by base64_decode($barcode). Here we use Data URI scheme to direct display the png in webpage., _(*12)

Usage in Twig template

This bundle extend one function of Twig: barcode which you can simply use it to generate barcode in the twig template., _(*13)

barcode use the same options, only different thing is your need pass a Twig array (it looks really like Json, but it isn't) in the function., _(*14)

• display html

{{ barcode({code: 'string to encode', type: 'c128', format: 'html'}) }}

• display svg

{{ barcode({code: 'string to encode', type: 'qrcode', format: 'svg', width: 10, height: 10, color: 'green'}) }}

• display png

<img src="data:image/png;base64,
{{ barcode({code: 'string to encode', type: 'datamatrix', format: 'png', width: 10, height: 10, color: [127, 127, 127]}) }}
" />

Usage without service

use Skies\SkiesQRcodeBundle\Generator\Generator;
//...
$options = array(
    'code'   => 'string to encode',
    'type'   => 'qrcode',
    'format' => 'html',
);

$generator = new Generator();
$barcode = $generator->generate($options);

return new Response($barcode);

Save Barcode in file

As you can see, the Bundle save nothing on the file system, But if you want to keep the barcode, No problem!, _(*15)

• save as html

$savePath = '/tmp/';
$fileName = 'sample.html';

file_put_contents($savePath.$fileName, $barcode);

• save as svg

$savePath = '/tmp/';
$fileName = 'sample.svg';

file_put_contents($savePath.$fileName, $barcode);

• save as png

$savePath = '/tmp/';
$fileName = 'sample.png';

file_put_contents($savePath.$fileName, base64_decode($barcode));
