在 laravel 中使用 maatwebsite excel 上传之前检查导入文件

Question

用于查看和导入的控制器

public function show(Request $request){
    $location=$request->file('import_file');
    if($request->hasFile('import_file')){
        $data =  Excel::selectSheets('Sheet1')->load($request->file('import_file'))->noHeading()->toArray();
        $result = array(
            'data'           =>$data,
            'page_header'    =>'Review Uploaded file',
            'location'       =>$location,  
      );
    }
            return view('admin.floorsheet.list', compact('result'));   

}

这里我得到了文件的位置，但它只获取临时位置而不是原始文件路径。

public function store(Request $request)
{
    if($request->hasFile('import_file')){
        Excel::load($request->file('import_file')->getRealPath(), function ($reader) {
            foreach ($reader->noHeading()->first()->toArray() as $key => $row) {
                $data['transaction'] = $row[1];
                $data['symbol'] = $row[2];
                $data['buyer'] = $row[3];
                $data['seller'] = $row[4];
                $data['quantity'] = $row[5];
                $data['rate'] = $row[6];
                $data['amount'] = $row[7];


                if(!empty($data)) {
                    DB::table('tbl_floorsheet')->insert($data);


                }
            }
        });
    }

    $result = array(

            'page_header'    =>'File Uploaded',
            'date'          =>date('Y-m-d'),
      );
            return view('admin.floorsheet.import',compact('result'));   
}

这里我已经在查看页面中成功显示了 table 中的 excel 文件。但是在使用视图页面上传文件时，我需要再次浏览文件。现在，我需要上传文件而无需再次浏览。当我在视图页面上使用该值时，它只获取临时文件路径而不是原始文件路径。

Answer 1

所以你有

$location = $request->file('import_file');

并获取原始文件名：

$location->getClientOriginalName();

需要添加路径存放：

$destinationPath = storage_path() .'/uploads'; $destinationName = date("YmdHis") .'_'. $location->getClientOriginalName(); $destinationFQN = "$destinationPath/$destinationName";

这个名字放在session里可以记住一会:

session()->put('filename', $location->getClientOriginalName()); $value = session()->get('filename'); session()->forget('filename');
