TP6框架--EasyAdmin学习笔记:excel的数据,图片处理
作者:互联网
这是我写的学习EasyAdmin的第七章,这一章我给大家分享下如何处理excel中的数据,图片
原理就是使用easyadmin中封装好的phpexcel,来进行数据的导入,view层我们需要一个用了导入excel的页面,代码如下:
<div class="layuimini-container"> <form id="app-form" class="layui-form layuimini-form"> <div class="layui-form-item"> <label class="layui-form-label">导入excel:</label> <div class="layui-input-block"> <button type="button" class="layui-btn" id="test1"> <i class="layui-icon"></i>上传文件 </button> </div> </div> </form> </div> <script src="/static/plugs/layui-v2.5.6/layui.all.js?v=2.0.0" charset="utf-8"></script> <script src="/static/plugs/jquery-3.4.1/jquery-3.4.1.min.js?v=2.0.0" charset="utf-8"></script> <script> layui.use('upload', function(){ var upload = layui.upload; var loading; //执行实例 var uploadInst = upload.render({ elem: '#test1' //绑定元素 ,url: '/admin/mall.goodsone/import' //上传接口 ,accept: 'file' ,choose:function(){ loading = layer.load(0, { shade: false, time: 60*60*1000 }); } ,done: function(res){ //上传完毕回调 layer.close(loading); if(res.msg == '导入成功'){ layer.msg(res.msg); } } ,error: function(){ layer.close(loading); //请求异常回调 } }); }); </script>
js中加入以下代码:
接下来就是重点,controller部分的代码,这里先在前面导入easyadmin封装好的phpexcel
use EasyAdmin\tool\CommonTool; use jianyan\excel\Excel;
在方法里写入下面代码
$file = request()->file('file'); ini_set('memory_limit','1024M'); $data = Excel::import($file);
$data里就是处理好的数据数组,但是实际用的时候会发现,图片没法识别,这里给出解决方法,亲测有用,大家可以照着思路来就行
PHPSpreadsheet
首先安装phpspreadsheet,由于线上服务器PHP版本是PHP5.6,所以需要安装兼容PHP5.6的版本,这里安装1.8.2版本
composer require phpoffice/phpspreadsheet=1.8.2
然后就可以在项目里使用了
use PhpOffice\PhpSpreadsheet\Cell\Coordinate; use PhpOffice\PhpSpreadsheet\IOFactory; $imageFilePath = './uploads/imgs/'; //图片本地存储的路径 if (!file_exists($imageFilePath)) { //如果目录不存在则递归创建 mkdir($imageFilePath, 0777, true); } try { $inputFileName = './files/1.xlsx'; //包含图片的Excel文件 $objRead = IOFactory::createReader('Xlsx'); $objSpreadsheet = $objRead->load($inputFileName); $objWorksheet = $objSpreadsheet->getSheet(0); $data = $objWorksheet->toArray(); foreach ($objWorksheet->getDrawingCollection() as $drawing) { list($startColumn, $startRow) = Coordinate::coordinateFromString($drawing->getCoordinates()); $imageFileName = $drawing->getCoordinates() . mt_rand(1000, 9999); switch ($drawing->getExtension()) { case 'jpg': case 'jpeg': $imageFileName .= '.jpg'; $source = imagecreatefromjpeg($drawing->getPath()); imagejpeg($source, $imageFilePath . $imageFileName); break; case 'gif': $imageFileName .= '.gif'; $source = imagecreatefromgif($drawing->getPath()); imagegif($source, $imageFilePath . $imageFileName); break; case 'png': $imageFileName .= '.png'; $source = imagecreatefrompng($drawing->getPath()); imagepng($source, $imageFilePath, $imageFileName); break; } $startColumn = ABC2decimal($startColumn); $data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName; } dump($data);die(); } catch (\Exception $e) { throw $e; } public function ABC2decimal($abc) { $ten = 0; $len = strlen($abc); for($i=1;$i<=$len;$i++){ $char = substr($abc,0-$i,1);//反向获取单个字符 $int = ord($char); $ten += ($int-65)*pow(26,$i-1); } return $ten; }
可以看到,图片被读取并存到了本地服务器中
PHPExcel
PHPExcel实现从Excel文件里读取内容的方法和phpspreadsheet几乎一样,毕竟phpspreadsheet就是在PHPExcel基础上写的,不过PHPExcel由于已经被废弃了,所以建议优先使用phpspreadsheet,如果原来项目里一直使用了PHPExcel也可以继续使用PHPExcel的方法
use PHPExcel_IOFactory; use PHPExcel_Cell; try { $inputFileName = './files/1.xlsx'; $inputFileType = PHPExcel_IOFactory::identify($inputFileName); $objReader = PHPExcel_IOFactory::createReader($inputFileType); $objPHPExcel = $objReader->load($inputFileName); } catch (\Exception $e) { die('加载文件发生错误:"'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage()); } $sheet = $objPHPExcel->getSheet(0); $data = $sheet->toArray(); //该方法读取不到图片,图片需单独处理 $imageFilePath = './uploads/imgs/'; //图片本地存储的路径 if (!file_exists($imageFilePath)) { mkdir($imageFilePath, 0777, true); } //处理图片 foreach ($sheet->getDrawingCollection() as $img) { list($startColumn, $startRow) = PHPExcel_Cell::coordinateFromString($img->getCoordinates()); //获取图片所在行和列 $imageFileName = $img->getCoordinates() . mt_rand(1000, 9999); switch($img->getExtension()) { case 'jpg': case 'jpeg': $imageFileName .= '.jpeg'; $source = imagecreatefromjpeg($img->getPath()); imagejpeg($source, $imageFilePath.$imageFileName); break; case 'gif': $imageFileName .= '.gif'; $source = imagecreatefromgif($img->getPath()); imagejpeg($source, $imageFilePath.$imageFileName); break; case 'png': $imageFileName .= '.png'; $source = imagecreatefrompng($img->getPath()); imagejpeg($source, $imageFilePath.$imageFileName); break; } $startColumn = ABC2decimal($startColumn); $data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName; } var_dump($data); public function ABC2decimal($abc) { $ten = 0; $len = strlen($abc); for($i=1;$i<=$len;$i++){ $char = substr($abc,0-$i,1);//反向获取单个字符 $int = ord($char); $ten += ($int-65)*pow(26,$i-1); } return $ten; }
