Without further ado, I will just post the code for you. The code is accompanied by comments. I believe everyone can understand it. If you have any questions you don’t understand, please leave me a message.
Front-end HTML JQuery Note Jquery requires version 1.x, version 2.x cannot be used
1. Introduce necessary files and upload input
<load file="__PUBLIC__/js/jquery-1.11.3.min.js" /> <load file="__PUBLIC__/uploadify/jquery.uploadify.min.js" /> <load file="__PUBLIC__/uploadify/uploadify.css" /> <input type="file" class="" id="student" name="student">
2.uploadify usage operation
<script> $(function(){ //ThinkPHP上传地址 var upload = "{:U(MODULE_NAME.'/Student/upload')}"; //ThinkPHP sessionID的提交变量 //'VAR_SESSION_ID'=>'session_id',在ThinkPHP/Conf/convention.php中进行配置,默认关闭的需要开启 var sid = '{:session_id()}'; //导入数据地址 var daoruUrl = "{:U(MODULE_NAME.'/Student/daoruHandle')}" //Amaze ui 模态框 var modal = $('#my-modal-loading'); //uploadify使用方法 $('#student').uploadify({ 'swf' : '__PUBLIC__/uploadify/uploadify.swf', 'uploader' : upload, 'buttonText' : '选择文件...', 'width':120, 'height':30, 'formData':{'session_id':sid}, 'fileTypeExts':'*.xls', //开始上传弹出模态框 'onUploadStart' : function(file) { $('#alert-content').html('正在上传文件'); modal.modal(); }, //上传成功关闭模态框,并用后台函数导入数据 'onUploadSuccess':function(file, data, response){ $('#alert-content').html('正在导入数据'); data = eval("("+data+")"); $.ajax({ type: 'POST', url: daoruUrl, data: {'file':data.file}, success: function(retdata){ modal.modal('close'); if(retdata==1){ alert('导入成功'); }else{ alert('导入失败'); } }, dataType: 'json' }); } }); }); </script>
3. ThinkPHP controller upload operation: Note that the Upload.class.php space needs to be introduced
function upload(){ $config = array( 'maxSize' => 3145728, 'rootPath' => './Uploads/', 'savePath' => '', 'saveName' => array('uniqid',''), 'exts' => array('xls'), 'autoSub' => true, 'subName' => array('date','Ymd'), ); $upload = new Upload($config); // 上传文件 $info = $upload->upload(); if(!$info) {// 上传错误提示错误信息 $this->error($upload->getError()); }else{// 上传成功 获取上传文件信息 $file = $info['Filedata']['savepath'].$info['Filedata']['savename']; } //p($info); $data = array( 'file'=>'./Uploads/'.$file, ); echo json_encode($data); }
4. Import data into mysql
//导入数据处理 function daoruHandle(){ $file = I('file'); $excelData = excel_to_mysql($file); foreach($excelData['data'] as $row){ $data = array( 'xuehao'=>$row['xuehao'], 'xingming'=>$row['xingming'], 'xingbie'=>($row['xingbie']=='男')?1:0, 'mima'=>md5($row['mima']), ); M('student')->add($data); } echo 1; }
5.PHPExcel reads Excel file and returns data function
function excel_to_mysql($file){ //导入PHPExcel第三方类库 //vendor('PHPExcel.PHPExcel'); import('Classes.PHPExcel',COMMON_PATH,'.php'); //实例化PHPExcel类,用于接收Excel文件 $PHPExcel = new PHPExcel(); //读取Excel文件类实例化 $PHPReader = new PHPExcel_reader_Excel5(); //检测Excel版本是否可读 if(!$PHPReader->canRead($file)){ $PHPReader = new PHPExcel_Reader_Excel2007(); if(!$PHPReader->canRead($file)) return array('error'=>1);//未知版本的Excel } //读取Excel文件 $PHPExcel = $PHPReader->load($file); //获得Excel中表的数量 $sheetCount = $PHPExcel->getSheetCount(); //获得第一张工作表 $sheet=$PHPExcel->getSheet(0); //获得表中最大数据列名 $column = $sheet->getHighestColumn(); //获得表中最大数据行名 $row = $sheet->getHighestRow(); //循环获得表中数据 for($i=1;$i<=$row;$i++){ $data[] = array( //通过工作表对象的getCell方法获得单元格 getValue方法获得该单元格数值 'xuehao'=>$sheet->getCell('A'.$i)->getValue(), 'xingming'=>$sheet->getCell('B'.$i)->getValue(), 'xingbie'=>$sheet->getCell('C'.$i)->getValue(), 'mima'=>$sheet->getCell('D'.$i)->getValue(), ); } //释放工作表对象 unset($sheet); //释放读取Excel文件对象 unset($PHPReader); //释放Excel文件对象 unset($PHPExcel); //返回数据 return array('error'=>0,'data'=>$data); }
ThinkPHP uploadify upload PHPExcel is implemented through the above code to import data without refreshing. I hope it will be helpful to everyone.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
