Laravel 10, in conjunction with JavaScript and certain extra tools, enables you to efficiently implement this feature. We will walk you through the stages of uploading files with a progress bar in Laravel 10 in this article.

Users of modern web applications frequently need to upload files, whether they are photographs, documents, or other media. A progress bar displayed during the file upload process can increase customer satisfaction and assist them understand the status of their uploads.

Let’s get started.

Laravel Installation

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Setup File Controller

Back to project terminal and run this command,

$ php artisan make:controller FileController

It will create FileController.php file inside /app/Http/Controllers folder.

Open file and write this code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FileController extends Controller
{
    public function index()
    {
        return view('file-upload');
    }
    
    public function store(Request $request)
    {
        $request->validate([
            'file' => 'required',
        ]);

        $fileName = time() . '.' . request()->file->getClientOriginalExtension();

        request()->file->move(public_path('files'), $fileName);

        return response()->json(['success' => 'You have successfully uploaded file.']);
    }
}

You will find all uploaded files in /public/files folder.

request()->file->move(public_path('files'), $fileName);
