View:

{{ Form::open(['files' => true]) }}

   {{ Form::file('my_pdf') }}

   {{ Form::submit('Upload') }}

{{ Form::close() }}

Controller:

if (Input::hasFile('my_pdf')) {

   // File was successfully uploaded and is now in temp storage.
   // Move it somewhere more permanent to access it later.

   if (Input::file('my_pdf')->move('path/to/destination/my.pdf')) {
       // File successfully saved to permanent storage

       
   } else {
       // Failed to save file, perhaps dir isn't writable. Give the user an error.
   }

}

Thank you sir @iWader . . . May i know how can I do that using HTML at view page?

if you have issues with what is entering your database, this is what you need to do.

public function store(Request $request)
{
    $this->validate($request,[
        'file' => 'required',
        'author'=>'required',
        'name'=>'required',
        'image'=>'required|image'
    ]);
    $file = Input::file('image');
    $image= \Image::make(\Input::file('image'));
    $path= public_path().'/books/';

    $image->save($path.$file->getClientOriginalName());
    $image->resize(498,580);
    $image->save($path.'thumb_'.$file->getClientOriginalName());


    $books= new book();

    $books->name  = $request->input('name');
    $books->author  = $request->input('author');
    $books->image = $file->getClientOriginalName();
    $extension = Input::file('file')->getClientOriginalExtension();
    $filename = rand(11111111, 99999999). '.' . $extension;
    $fullPath = $filename;

    $request->file('file')->move(
        base_path() . '/public/pdf/', $filename
    );
    $books->file = $fullPath;

    if ($books->save())
    {
        return redirect()->back()->with('alert','Your book has been uploaded');
    }
    return redirect()->back()->withErrors($validate);
}
