Currently, file management is a fundamental part of many web applications. Laravel, as one of the most popular development frameworks, offers robust and efficient tools for file uploads. In this article, I present a complete guide on how to accomplish this task in Laravel 11, covering everything from initial setup to implementation in a project.

Prerequisites
Before you begin, you need to have Laravel 11 installed and have a local server or domain to test your application. Additionally, it is recommended to have basic knowledge of PHP and a general understanding of how Laravel works.
Environment Setup
To start uploading files, you first need to ensure your environment is properly configured. Open the terminal and navigate to your Laravel project folder. Also, make sure that the directory where you will store the files has write permissions.
Route Configuration
In the routes/web.php file, you need to define a route that will handle the request to upload files. You can add something like the following:
Route::get('upload', 'FileUploadController@create');
Route::post('upload', 'FileUploadController@store');This allows your application to respond to a GET request to display the file upload form and a POST request to process the upload.
Creating the Controller
Next, create a controller that will manage the file upload logic. Use the following command in your terminal:
php artisan make:controller FileUploadController
Within the controller, define two methods: create to show the form and store to handle the file upload. Here’s a simple example:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class FileUploadController extends Controller
{
public function create()
{
return view('upload');
}
public function store(Request $request)
{
$request->validate([
'file' => 'required|file|mimes:jpg,png,pdf|max:2048',
]);
$file = $request->file('file');
$fileName = time() . '_' . $file->getClientOriginalName();
$file->move(public_path('uploads'), $fileName);
return back()->with('success', 'File successfully uploaded: ' . $fileName);
}
}Creating the View
Now it’s time to create the view where the user can select a file to upload. Create a view file at resources/views/upload.blade.php with the following content:
<!DOCTYPE html>
<html>
<head>
<title>Upload File</title>
</head>
<body>
<h1>Upload File</h1>
@if (session('success'))
<p>{{ session('success') }}</p>
@endif
<form action="{{ url('upload') }}" method="POST" enctype="multipart/form-data">
@csrf
<input type="file" name="file" required>
<button type="submit">Upload</button>
</form>
</body>
</html>Here, the form includes an input for file selection and a button to submit it. The @csrf directive is used to protect against CSRF attacks, ensuring that only legitimate requests from your application are accepted.
Testing File Upload
Now that you have set up the controller and the view, it’s time to test the functionality. Open your browser and navigate to the route you defined for the upload form. When you select a file and submit it, you should see a success message.
Conclusion
Uploading files in Laravel 11 is a straightforward process that, with the right configuration, you can quickly implement in your application. This functionality not only enhances user interaction but is also essential for many types of web applications.
