Error: Class 'Picqer\Barcode\BarcodeGenerator' not found

[anuj9196]

I'm using php-barcode-generator in CakePHP framework.
I have installed plugin in vendor directory and using it in my controller

require_once(ROOT.'/vendor/picqer/php-barcode-generator/src/BarcodeGeneratorHTML.php');
  public function shippingSlipPrint($order_id = null)
    {
        $generator = new BarcodeGeneratorHTML();
        $barcode = $generator->getBarcode('1234567890', $generator::TYPE_CODE_128);

        $this->set('barcode', $barcode);

    }

But this is giving error as

Error: Class 'Picqer\Barcode\BarcodeGenerator' not found
File /myapp/vendor/picqer/php-barcode-generator/src/BarcodeGeneratorHTML.php
Line: 6 

content of BarcodeGeneratorHTML.php

<?php

namespace Picqer\Barcode;

class BarcodeGeneratorHTML extends BarcodeGenerator
{
     .....
    ......
}

Then you also need to require the ROOT . '/vendor/picqer/php-barcode-generator/src/BarcodeGenerator.php' file

With Composer we use Autoload, which loads this files automatically.

I am having a similar issue as I could not use composer.

Please advise

[casperbakker]

It is just basic PHP, require/include the proper file before you can use it.

I fixed the problem by requiring autoload file.

Thanks and keep up the good work
