How to upload the pdf/doc file in laravel through validation

I am trying to make a website where the user will be able to upload the pdf and doc file. Also, I want to save the file in the storage folder so I made the symlink so it would replicate the folder in the Public folder. SO I have a folder called Public/storage/Paper in public. This is my form where the user will be able to upload the paper.

     <form class="form-horizontal" method="post" action="paper" enctype="multipart/form-data">
            @csrf
       <div class="form-group">
    <label for="title">Title of Paper</label>
    <input type="text" class="form-control" name="title"  placeholder="Title of Paper" required="required">
</div>
<div class="form-group">
    <label for="Paper">Upload Paper</label>
    <input type="file" class="form-control" name="paper" required="required" >
</div>

<button type="submit" class="btn btn-primary">Submit</button>

On my controller, I wrote this code, this works perfectly fine like saving the data in the database when I don't need to upload the file. But when I need to upload the paper the validation doesn't pass.

<?php
    namespace App\Http\Controllers;
     use App\Submission;
     use Illuminate\Support\Facades\DB;
     use Illuminate\Support\Facades\Validator;
     use Illuminate\Http\Request;
     use Illuminate\Support\Facades\File;
    use Illuminate\Support\Facades\Storage;
     class PapersController extends Controller
   {


     public function  store(Request $request){

        $request->validate([
        'title'=>'required',
          'paper'=>'required'

      ]);


           $title= $request->input('title');
          Validator::make($request->all(),['paper'=>"required|string|mimes:pdf,zip"])->validate();
         $extension= $request->file("file")->getClientOriginalExtension();
          $stringPaperFormat=str_replace(" ", "", $request->input('title'));
           $fileName= $stringPaperFormat.".".$extension;
            $FileEnconded=  File::get($request->paper);
            Storage::disk('local')->put('public/Paper'.$fileName, $FileEnconded);
            $newsubmission= array("title"=>$title, "paper"=>$fileName);
             $created= DB::table('submissions')->insert($newsubmission);
             if($created){
                  return "Sucessful";
                         }else{
                    return "Not Sucessful";
                                }
                          }
                        }

I am not being able to detect the problem. Any kind of help will be appreciated.

Hi @pathsush

And what if you remove this line (you dont check if the validation passed/fails here)

Validator::make($request->all(),['paper'=>"required|string|mimes:pdf,zip"])->validate();

And change

$request->validate([
        'title'=>'required',
         'paper'=>'required'
 ]);

$request->validate([
        'title'=>'required',
         'paper'=>'nullable|mimes:pdf,zip'
 ]);

And remove the 'require' from your form field.

<input type="file" class="form-control" name="paper" >

Now the paper file is optional (paper file is not required), if there is a file there is validation to check it's a pdf or zip.

Not sure if the paper file always must be required. But if this is the case change nullable to required off course
