yii2.0框架实现上传excel文件后导入到数据库的方法示例

本文实例讲述了yii2.0框架实现上传excel文件后导入到数据库的方法。分享给大家供大家参考，具体如下：

Model模型

 false,'extensions' => 'xls,xlsx'],
    ];
  }

  public function attributeLabels()
  {
    return [
      'file'=> '上传文件'
    ];
  }

  public function upload()
  {
    $file = UploadedFile::getInstance($this, 'file');

    if ($this->rules()) {
      $tmp_file = $file->baseName . '.' . $file->extension;
      $path = 'upload/' . 'Files/';
      if (is_dir($path)) {
        $file->saveAs($path . $tmp_file);
      } else {
        mkdir($path, 0777, true);
      }
      $file->saveAs($path . $tmp_file);
      return true;
    } else {
      return '验证失败';
    }
  }

}

Views视图

 'upload',
  'options' => ['enctype' => 'multipart/form-data'],
])
?>

field($model,'file')->fileInput(['multiple'=>'multiple']) ?>

  上传

Controller控制器

request->isPost) {
      $model->file = UploadedFile::getInstance($model,'file');
//      if ($model->upload()) {
//        print <<alert('上传成功')
//EOT;
//      } else {
//        print <<alert('上传失败')
//EOT;
//      }
      if (!$model->upload()) {
        print <<alert('上传失败')
EOT;
      }
    }

    $ok = 0;
    if ($model->load(Yii::$app->request->post())) {
      $file = UploadedFile::getInstance($model,'file');

      if ($file) {
        $filename = 'upload/Files/' . $file->name;
        $file->saveAs($filename);

        if (in_array($file->extension,array('xls','xlsx'))) {
          $fileType = \PHPExcel_IOFactory::identify($filename);//文件名自动判断类型
          $excelReader = \PHPExcel_IOFactory::createReader($fileType);

          $phpexcel = $excelReader->load($filename)->getSheet(0);//载入文件并获取第一个sheet
          $total_line = $phpexcel->getHighestRow();//总行数
          $total_column = $phpexcel->getHighestColumn();//总列数

          if (1 < $total_line) {
            for ($row = 2;$row <= $total_line;$row++) {
              $data = [];
              for ($column = 'A';$column <= $total_column;$column++) {
                $data[] = trim($phpexcel->getCell($column.$row));
              }

              $info = Yii::$app->db->createCommand()
->insert('{{%shop_info}}',['shop_name' => $data[0],'shop_type' => $data[1]])
->execute();

              if ($info) {
                $ok = 1;
              }
            }
          }

          if ($ok == 1) {
            echo "";
          } else {
            echo "";
          }
        }
      }
    } else {
      return $this->render('import',['model' => $model]);
    }
  }
}
