Thinkphp使用phpexcel导入文件并写入数据库

Posted 2020-08-24 诀别~雪

现实中，我们往往很多地方都需要这样批量导入数据，除了phpexcel还有csv等方法可以解决

下面详细介绍一下使用方法

首先在官方下载安装包解压到本地，然后复制保存到tp框架下的vendor目录下

html页面如下

下面是后端代码：

public function column(){
        $grade=D(\'school\')->where(array(\'parent_id\'=>1))->select();
        $school = D(\'schooll\')->select();
        $this->assign(\'school\',$school);
        $this->assign(\'grade\',$grade);
        if(IS_POST){
          $data_p = I(\'post.\');
        if ($data_P[\'sno\']==\' \') {
                 $this->ajaxReturn(array(\'nr\' => \'学号已存在!\', \'sf\' => 0));
          }elseif($data_P[\'sname\']==\' \'){
                 $this->ajaxReturn(array(\'nr\' => \'姓名不为空!\', \'sf\' => 0));
            }elseif($data_P[\'grade\']==\' \'){
                  $this->ajaxReturn(array(\'nr\'=> \'不为空\',\'sf\'=>\'0\'));
            }elseif($data_P[\'major\']==\' \'){
                  $this->ajaxReturn(array(\'nr\'=>\'不为空\',\'sf\'=>\'0\'));
            }elseif($data_P[\'classs\']==\' \'){
                  $this->ajaxReturn(array(\'nr\'=>\'不为空\',\'sf\'=>\'0\'));
            }elseif($data_P[\'school\']==\' \'){
                  $this->ajaxReturn(array(\'nr\'=>\'不为空\',\'sf\'=>\'0\'));
            }else{
          $student = M(\'student\')->add(array(\'sno\'=>$data_p[\'sno\'],\'passwd\'=>md5($data_p[\'passwd\']),\'sname\'=>$data_p[\'sname\'],\'zt\'=>$data_p[\'checkresult\'],\'majorname\'=>$data_p[\'major\'],\'classname\'=>$data_p[\'classs\'],\'gradename\'=>$data_p[\'school\'],\'schoolname\'=>$data_p[\'grade\']));
              }
              if ($student) {
                        $this->ajaxReturn(array(\'nr\' => \'添加成功\'.$data_P[\'major\'], \'sf\' => 0));
                    } else {
                        $this->ajaxReturn(array(\'nr\' => \'添加失敗!\', \'sf\' => 0));
                      }
                  }
         $this->display(\'index/column\');
        }

        public function upload() {
                if (!empty($_FILES)) {
                  $config = array(
                \'exts\' => array(\'xlsx\',\'xls\'),
                \'maxSize\' => 3145728,
                \'rootPath\' =>"./Excel/",
                \'subName\' => array(\'date\',\'Ymd\'),
           );

           $upload = new \\Think\\Upload($config);

            if (!$info = $upload->upload()){

               $this->error($upload->getError());
                
              }else{
          
           //vendor(\'PHPExcel.PHPExcel\');/////引入类库

           //vendor(\'PHPExcel.Reader.Excel5\');
           import("vendor.PHPExcel");
           import("vendor.PHPExcel.Reader.Excel5");
           $objPHPExcel = new \\PHPExcel();/////初始化引入的方法

           $PHPReader=new \\PHPExcel_Reader_Excel5();

          $file_name=$upload->rootPath.$info[\'excel\'][\'savepath\'].$info[\'excel\'][\'savename\'];
            }
            $objReader = $PHPReader->load($file_name);
              
         $extension = strtolower(pathinfo($file_name, PATHINFO_EXTENSION));
              //判断导入表格后缀格式
                if ($extension == \'xlsx\') {

                    $objReader =\\PHPExcel_IOFactory::createReader(\'Excel2007\');

                    $objPHPExcel =$objReader->load($file_name, $encode = \'utf-8\');
                      
                } elseif($extension == \'xls\'){

                    $objReader =\\PHPExcel_IOFactory::createReader(\'Excel5\');

                    $objPHPExcel =$objReader->load($file_name, $encode = \'utf-8\');
                       
               }

          $sheet =$objPHPExcel->getSheet(0);//获取表中第一个工作表

          $highestRow = $sheet->getHighestRow();//取得总行数

          $highestColumn =$sheet->getHighestColumn(); //取得总列数
          
          for($currentRow=1;$currentRow<=$highestRow;$currentRow++){

            for($currentColumn=\'A\';$currentColumn<=$highestColumn;$currentColumn++){
              $address=$currentColumn.$currentRow;
              $arr[$currentRow][$currentColumn]=$sheet->getCell($address)->getValue();
            }
      for ($i = 2; $i <= $highestRow; $i++) {

          $data_p[\'sno\'] =$objPHPExcel->getActiveSheet()->getCell("A" . $i)->getValue();

         $passwd =$objPHPExcel->getActiveSheet()->getCell("B" .$i)->getValue();

            $data_p[\'passwd\']=md5($passwd);

         $data_p[\'sname\'] =$objPHPExcel->getActiveSheet()->getCell("C" .$i)->getValue();

         $data_p[\'zt\'] = \'0\';

         $data_p[\'majorname\'] = $objPHPExcel->getActiveSheet()->getCell("D". $i)->getValue();

         $data_p[\'classname\'] =$objPHPExcel->getActiveSheet()->getCell("E" .$i)->getValue();

         $data_p[\'gradename\'] =$objPHPExcel->getActiveSheet()->getCell("F" . $i)->getValue();

         $data_p[\'schoolname\'] =$objPHPExcel->getActiveSheet()->getCell("G" . $i)->getValue();

         $ex=M(\'Student\')->add($data_p);
              }
      if($ex){
                $this->success(\'导入成功!\');
         }else{
                $this->error("请选择上传的文件");

                  }

　　　　}
}
             

         好的具体的就是这些。哪里不懂可以留言[e-mail]咨询。
