Undefined variable: request

Question

When I tried to upload the file it shows error:

Undefined variable: request

This is where I used it: UploadController:

if($request->hasFile('file')){
        $file = $request ->file('file');
        $fileName = $file->getClientOriginalName();
        $destinationPath = config('app.fileDesinationPath').'/'.$fileName;
        $uploads = Storage::put($destinationPath,file_get_contents($file->getRealPath()));

    }
    return redirect()->to('/upload');

What's wrong here?

Answer 1

Add Request $request parameter in your function. Example:

public function yourFunction(Request $request)
{
    if($request->hasFile('file')){
        $file = $request ->file('file');
        $fileName = $file->getClientOriginalName();
        $destinationPath = config('app.fileDesinationPath').'/'.$fileName;
        $uploads = Storage::put($destinationPath,file_get_contents($file->getRealPath()));

    }
    return redirect()->to('/upload');
}

Please read the documentation thoroughly: http://laravel.com/docs

You can also use request() helper function as:

if(request()->hasFile('file')) {
    ...
}

The request function returns the current request instance.
