在dompdf中打印条形码的最佳实践

I want to create a label sticker with barcode in PDF. Please give me the suggestion to create this things. Now , I use CI3 and dompdf.

I have tried googling a lot of time, but I am not found the best practice to realized this thing.

I followed your suggestion, Now I have folder in vendor/Piqcer.

I try this into my view_report like this:

<tr>
   <td class="solid" colspan="2">
      <?= $value->NO_URUT ?>
      <?php
          $generator = new \Picqer\Barcode\BarcodeGeneratorPNG();
          echo '<img src="data:image/png;base64,' . base64_encode($generator->getBarcode($value->NO_URUT, $generator::TYPE_CODE_128)) . '">';
      ?>
   </td>
</tr>

But I got error :

Fatal error: Class 'Picqer\Barcode\BarcodeGeneratorPNG' not found

UPDATE

So, this library is on ci_folder\vendor\picqer\php-barcode-generator. Now I create an autoload library like this :

class Barcode {

public function generate($id) {
    require_once("./vendor/picqer/php-barcode-generator/src/BarcodeGeneratorJPG.php");
    $generator = new Picqer\Barcode\BarcodeGeneratorJPG();
    echo $generator->getBarcode($id, $generator::TYPE_CODE_128);
}

}

IN my controller :

$this->load->library('dompdfgenerator');
$this->load->library('barcode');

 $data = array(
        'result' => $result,
        'container' => $containers
    );

  $html = $this->load->view('members/megumi/check_list_per_tanggal/v_laporan_sticker_pilihan', $data, true);
  $this->dompdfgenerator->generate($html, "$identity");

Now in view :

<tr>
    <td class="solid" colspan="2">
     <?= $value->NO_URUT ?>
     <?php
        echo '<img src="data:image/png;base64,' . base64_encode($this->barcode->generate($value->NO_URUT)) . '">';
      ?>

     </td>
</tr>

It still : Fatal error: Class 'Picqer\Barcode\BarcodeGenerator' not found

Please advise...

Have you tried using libraries, such as PHP Barcode Generator. It will generate a barcode for you and export it as an SVG, PNG or JPG or HTML. You should just insert the resulting barcode to the HTML you wil lbe exporting with DOMPDF.

I think you may get some idea from this answer Integrate barcode reader generate/read with Codeigniter. Also note that the files of BarcodeGenerator are stored in the third_party folder of the application.
