Install Laravel 11 Fresh Project
Before starting work we need to install laravel 11 project. Using below command a fresh laravel 11 project will be installed in system
composer create-project --prefer-dist laravel/laravel laravel11-fileupload
Create Routes for Accepting and Forwarding Request
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\FileUploadController;
Route::get('/upload', [FileUploadController::class, 'showForm'])->name('upload.form');
Route::post('/upload', [FileUploadController::class, 'uploadFile'])->name('upload.file');
Create FileUploadController Class
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class FileUploadController extends Controller
{
public function showForm()
{
return view('upload');
}
public function uploadFile(Request $request)
{
$request->validate([
'file' => 'required|mimes:pdf,doc,docx,xls,xlsx|max:5120', // Max file size: 5MB and allow pdf,doc,docx,xls,xlsx file
]);
if ($request->file('file')) {
$file = $request->file('file');
$fileName = time() . '_' . $file->getClientOriginalName();
$file->storeAs('uploads', $fileName, 'public'); // Save to public/uploads
return back()->with('success', 'File uploaded successfully!')->with('file', $fileName);
}
return back()->with('error', 'Please select a file.');
}
}

Run Project and Upload File
php artisan serve
This will start and serve project on http://127.0.0.1:8000; After that visit route /upload and try to upload image file. This will show file validation error. As we have added public directory uploads, so file will be uploaded inside storage/app/public/uploads directory. You can then create storage:link by running command php artisan storage:link
