本文实例讲述了thinkPHP框架实现生成条形码的方法。分享给大家供大家参考,具体如下:
在做之前我们先下载barcode类,想下载该类可以点击此处本站下载。
我们在后台写一个方法代码如下:
//生成条形码 public function barcode(){ import('@.ORG.Util.barcode.BCGFontFile');//字体类 import('@.ORG.Util.barcode.BCGColor');//字体颜色类 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"'); $drawing->finish(\BCGDrawing::IMG_FORMAT_PNG); }
在前台直接调用:
<img src="{:U('ContractCommonApply/barcode')}/text/{$res[0]['ContractCode']}" style="margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";"><script type="text/javascript" language="JavaScript"> document.writeln("<img src=/目录/test_1D.php?text=内容 />"); </script>
希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
