C128 Barcode script in php

2.6k views Asked by At

I want to add code 128 auto barcode in codeigniter framework.I used http://davidscotttufts.com/2009/03/31/how-to-create-barcodes-in-php/ for this but it is generating code128B format.I have also used http://www.barcodephp.com/en/download but could not be able to properly add classes in codeigniter framework.Can anyone help me or suggest me code128 auto barcode php script.

Thanks in advance

<?php


    // Get thickness parameter from $_GET:
    $thickness = ( isset( $_GET["thickness"] ) ? $_GET[ "thickness" ] : 2 );

    //$text=(int)$text;
    $size = (isset($_GET["size"])?$_GET["size"]:"30");
    $orientation = (isset($_GET["orientation"])?$_GET["orientation"]:"horizontal");
    $code_type = (isset($_GET["codetype"])?$_GET["codetype"]:"code128");
    $code_string = "";

    // Translate the $text into barcode the correct $code_type

You can actually follow the examples at https://github.com/tecnickcom/tc-lib-barcode/blob/develop/example/index.php

For example:

$bobj = $barcode->getBarcodeObj('QRCODE,H', 'hello world', -4, -4, 'black');
echo "<img alt=\"Embedded Image\" src=\"data:image/png;base64,".base64_encode($bobj->getPngData())."\" />";

or if you want to print the barcode in a different format:

echo $bobj->getHtmlDiv();

The examples uses the tc-lib-barcode (https://github.com/tecnickcom/tc-lib-barcode) PHP Software library to generate both linear and bidimensional barcodes.

The source code is fully PSR-2 compliant and can be easily added to your PHP projects using Composer.

The original code has been ported and refactored from TCPDF and already used in billions of documents.
