mysql - 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 Controller

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'));   

}

这里我已经获取了文件的位置，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'));   
}

这里我已经成功地在 View 页面的表格中显示了Excel文件。但是，在使用 View 页面上传文件时，我需要再次浏览该文件。现在，我需要上传文件而不再次浏览。当我使用 View 页面上的值时，它仅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();

您需要为其添加存储路径:

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

如果将其放入 session 中，您可以记住该名称一段时间:

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