By Hardik Savani April 12, 2023 Category : Laravel

Hello Friends,

Are you looking for an example of laravel file upload example. This article will give you a simple example of laravel file upload validation. step by step explain laravel file upload example. We will use laravel upload photo example. So, let us see in detail an example.

In this tutorial, we will create two routes one for the get method to render forms and another for the post method to upload file code. we created a simple form with file input. So you have to simply select a file and then it will upload in the "uploads" directory of the public folder.

So you have to simply follow below steps and get the file upload in laravel 10 application.

Step 1: Install Laravel

This step is not required; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Create Controller

In this step, we will create a new FileController; in this file, we will add two method index() and store() for render view and store file logic.

Let's create FileController by following command:

php artisan make:controller FileController

next, let's update the following code to Controller File.

app/Http/Controllers/FileController.php

<?php
    
namespace App\Http\Controllers;
     
use Illuminate\Http\Request;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;
    
class FileController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(): View
    {
        return view('fileUpload');
    }
      
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request): RedirectResponse
    {
        $request->validate([
            'file' => 'required|mimes:pdf,xlx,csv|max:2048',
        ]);
      
        $fileName = time().'.'.$request->file->extension();  
       
        $request->file->move(public_path('uploads'), $fileName);
     
        /*  
            Write Code Here for
            Store $fileName name in DATABASE from HERE 
        */
       
        return back()
            ->with('success','You have successfully upload file.')
            ->with('file', $fileName);
   
    }
}

Store File in Storage Folder

$request->file->storeAs('uploads', $fileName);
  
// storage/app/uploads/file.png

Store File in Public Folder

$request->file->move(public_path('uploads'), $fileName);
  
// public/uploads/file.png

Store File in S3

$request->file->storeAs('uploads', $fileName, 's3');

Step 3: Create and Add Routes

Furthermore, open routes/web.php file and add the routes to manage GET and POST requests for render view and store file logic.

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\FileController;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::get('file-upload', [FileController::class, 'index']);
Route::post('file-upload', [FileController::class, 'store'])->name('file.store');

Step 4: Create Blade File

At last step we need to create fileUpload.blade.php file and in this file we will create form with file input button. So copy bellow and put on that file.

resources/views/fileUpload.blade.php

<!DOCTYPE html>
<html>
<head>
    <title>Laravel 10 File Upload Example - ItSolutionStuff.com</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet">

            <div class="alert alert-success alert-block">
                <strong>{{ $message }}</strong>
            </div>
        @endif
      
        <form action="{{ route('file.store') }}" method="POST" enctype="multipart/form-data">
            @csrf
  
            <div class="mb-3">
                <label class="form-label" for="inputFile">File:</label>
                <input 
                    type="file" 
                    name="file" 
                    id="inputFile"
                    class="form-control @error('file') is-invalid @enderror">
  
                @error('file')
                    <span class="text-danger">{{ $message }}</span>
                @enderror
            </div>
   
            <div class="mb-3">
                <button type="submit" class="btn btn-success">Upload</button>
            </div>
       
        </form>
