Method Example of Generating Bar Code Based on thinkPHP Framework

In this paper, an example is given to describe the method of generating barcode by thinkPHP framework. Share it for your reference, as follows:

Before we do it, we download barcode class first. If you want to download this class, you can click here to download it.

We write a method code in the background as follows:

// Generate barcode 
public function barcode(){
  import('@.ORG.Util.barcode.BCGFontFile');// Font class 
  import('@.ORG.Util.barcode.BCGColor');// Font color class 
  import('@.ORG.Util.barcode.BCGDrawing');
  import('@.ORG.Util.barcode.BCGcode39');
  $text = $_GET['text'];
  $texts = isset($text)?$text:'00000000000';
  $color_black = new \BCGColor(0,0,0);
  $color_white = new \BCGColor(255,255,255);
  $drawException = null;
  try {
    $code = new \BCGcode39();
    $code->setScale(2);
    $code->setThickness(30);
    $code->setForegroundColor($color_black);
    $code->setBackgroundColor($color_white);
    $code->parse($texts);
  } catch(Exception $exception) {
    $drawException = $exception;
  }
  $drawing = new \BCGDrawing('', $color_white);
  if($drawException) {
    $drawing->drawException($drawException);
  } else {
    $drawing->setBarcode($code);
    $drawing->draw();
  }
  header('Content-Type: image/png');
  header('Content-Disposition: inline; filename="barcode.png"');
  $drawing->finish(\BCGDrawing::IMG_FORMAT_PNG);
}

Call directly from the foreground:

<img src="{:U('ContractCommonApply/barcode')}/text/{$res[0]['ContractCode']}" alt="">

The code called with js is as follows:

<script type="text/javascript" language="JavaScript">
  document.writeln("<img src=/ Directory /test_1D.php?text= Content  />");
</script>

PS: Here we recommend a similar barcode generation tool for your reference:
