tp5(thinkphp5)excel导入数据库(tp5.1遇到的坑)

记录一下遇到的坑 我花了2个小时在引入文件上,tp5.1已经废弃了import函数和vendor函数,这里我们用require或者include都可以.

贴代码:

前端:

    


    
    

        上传文件:
        
    
    

表设计:

 

CREATE TABLE `test` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4;

控制器:

public function upload()
    {   
        // 引入核心文件
        require'../extend/PHPExcel/PHPExcel.php'; 
        header("content-type:text/html;charset=utf-8");
        //上传excel文件
        $file = request()->file('excel');
        $files = $_FILES['excel'];
        //将文件保存到public/uploads目录下面
        $info = $file->validate(['size'=>1048576,'ext'=>'xls,xlsx'])->move( './uploads');
        if($info){
            //获取上传到后台的文件名
            $fileName = $info->getSaveName();
            //获取文件路径
            $filePath = Env::get('root_path').'public'.DIRECTORY_SEPARATOR.'uploads'.DIRECTORY_SEPARATOR.$fileName;
            //获取文件后缀
            $suffix = $info->getExtension();
            //判断哪种类型
            if($suffix=="xlsx"){
                $reader = \PHPExcel_IOFactory::createReader('Excel2007');
                }else{
                $reader = \PHPExcel_IOFactory::createReader('Excel5'); 
                }
            }else{
                $this->error('文件过大或格式不正确导致上传失败-_-!');
            }
        $objContent = $reader -> load($files['tmp_name']);
        $sheetContent = $objContent -> getSheet(0) -> toArray();
        unset($sheetContent[0]);
        foreach ($sheetContent as $k => $v){
            $arr['id'] = $v[0];
            $arr['title'] = $v[1];
            $res[] = $arr;
        }
        $res = Db::name('test') -> insertAll($res);
        if($res){
            echo "成功";
        }else{
            echo "失败";
        }
    }
