Route::get('/',[UserController::class,'index']);
Route::post('/users/fileupload/',[UserController::class,'fileupload'])->name('users.fileupload');

<?php

namespace App\Http\Controllers;

use App\Models\User;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index(){
        return view('users');
      }
    
      public function fileupload(Request $request){
    
         if($request->hasFile('file')) {
    
           $destinationPath = 'files/';
    
           $extension = $request->file('file')->getClientOriginalExtension();
    
           $validextensions = array("jpeg","jpg","png","pdf");
    
           if(in_array(strtolower($extension), $validextensions)){
    
             $fileName = time() . $request->file('file')->getClientOriginalName();
             $request->file('file')->move($destinationPath, $fileName); 
    
           }
    
         }
      }    
}

Step 3: Create view

In this step we will create users.blade.php file for dropzone file upload code.

<!DOCTYPE html>
<html>
  <head>
    <title>Drag and Drop file upload with Dropzone in Laravel 7</title>

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <meta charset="utf-8">
    <meta name="csrf-token" content="{{ csrf_token() }}">

    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/dropzone/5.4.0/min/dropzone.min.css">
    <script src="https://cdnjs.cloudflare.com/ajax/libs/dropzone/5.4.0/dropzone.js"></script>

  </head>
  <body>

    <div class='content'>
      <!-- Dropzone -->
      <form action="{{route('users.fileupload')}}" class='dropzone' >
      </form> 
    </div> 

    <!-- Script -->
    <script>
    var CSRF_TOKEN = document.querySelector('meta[name="csrf-token"]').getAttribute("content");

    Dropzone.autoDiscover = false;
    var myDropzone = new Dropzone(".dropzone",{ 
        maxFilesize: 3,  // 3 mb
        acceptedFiles: ".jpeg,.jpg,.png,.pdf",
    });
    myDropzone.on("sending", function(file, xhr, formData) {
       formData.append("_token", CSRF_TOKEN);
    }); 
    </script>

  </body>
</html>
