README

SGKBarcodeBundle is a Symfony3 / 4 Barcode Generator Bundle.

Features:

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

Installation

Add SGKBarcodeBundle by running the command:

$ php composer.phar require sgk/barcode-bundle:v2.0.0

Or, add SGKBarcodeBundle to your composer.json, then execute php composer.phar update

"require": {
        "sgk/barcode-bundle": "v2.0.0"
    }

Composer will install the bundle to your project's vendor/sgk directory.

Then, Enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new SGK\BarcodeBundle\SGKBarcodeBundle(),
    );
}

If you are using Symfony 4 with Flex the line should have automatically been added to config/bundles.php

Generate options

To generate one barcode, you have 5 options can be configured.

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)

Usage by service

This is deprecated in version 3.4 and will break in Symfony 4. See 'usage without service' instead.

The bundle registers one service: sgk_barcode.generator which will allows you to generate barcode:

outpout html

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

$barcode =
    $this->get('sgk_barcode.generator')->generate($options);
    
return new Response($barcode);

outpout svg

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

$barcode =
    $this->get('sgk_barcode.generator')->generate($options);
    
return new Response($barcode);

outpout png

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

$barcode =
    $this->get('sgk_barcode.generator')->generate($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.

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.

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.

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 SGK\BarcodeBundle\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!

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));

Supported Barcode Types

Please read Wikipedia page to know which type you should choice.

2d barcodes

1d barcodes

Requirements

If there is some problem of requirements, make sure you have install these two extensions of PHP (check in your phpinfo()).

Barcodes requires GD and ImageMagick to create PNGs in PHP 5.3.
Barcodes requires PHP bcmath extension for Intelligent Mail barcodes

Tests

To execute unit tests, composer install and run:

phpunit --coverage-text
