Question

I am trying to use the Maatwebsite\Excel package to let users import a csv or excel file and it get imported into the DB. Also i am storing my excel sheet into the public/uploads folder and after that I am executing the Export function. You can check this logic into my controller so far my file goes into the public/uploads folder.

I keep getting the error this error .

Controller

public function uploadCsvQuizFile(Request $request){

        $file = $request->uploading_file;


        //dd($file);
        //Display File Name
        $file_name = $file->getClientOriginalName();
        echo '<br>';
        //Display File Extension
        echo 'File Extension: '.$file->getClientOriginalExtension();
        echo '<br>';
        //Display File Real Path
        echo 'File Real Path: '.$file->getRealPath();
        echo '<br>';
        //Display File Size
        echo 'File Size: '.$file->getSize();
        //Display File Mime Type
        echo 'File Mime Type: '.$file->getMimeType();
        //Move Uploaded File
        $destinationPath = public_path().'\uploads';
        $file->move($destinationPath,$file->getClientOriginalName());

        $data = Excel::import(new QuizImport,public_path('\uploads\file.xlsx'));

        if($data){
            return redirect()->back()->with('success','Quiz Updated Successfully');
        }else{
            return redirect()->back()->with('error','Something Went Wrong');
        }

    }
