Based on ThinkPHP uploadify upload PHPExcel import data without refreshing_php tips

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.
