Laravel 9 File Upload Step by Step Example

Laravel ·

Teams applying “Laravel 9 File Upload Step by Step Example” in a production project can use this detailed guide to record implementation, review and debugging time, then compare that effort with tests and shipped functionality instead of treating activity as performance by itself.

Before copying the example into a live application, confirm version-specific behaviour with the official Laravel website and test it against the project’s actual database and runtime.

Hi friends,

This tutorial shows you laravel 9 file upload step by step. this example will help you upload a file in laravel 9 with validation. We will use the laravel 9 upload file and display the message validation. I would like to share with you how to upload file in laravel 9 into the database and storage directory with validation. So, let's follow few steps to create an example of a file upload form in laravel 9.

And as well as, how to validate file mime type, size, dimension, etc on laravel controller by using laravel 9 validation rules.

This file upload in the tutorial will create a file upload form in laravel 9 with validation, which is used to store files in the database and storage directory.

This tutorial will work with Laravel versions 5, 6, 7, and 8. When syntax is different across versions, the different syntax will be demonstrated.

Let's start following example:

Step 1: Download Laravel


Let us begin the tutorial by installing a new laravel application. if you have already created the project, then skip following step. 

composer create-project laravel/laravel example-app

Step 2 : Add Controller

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

Let's create FileUploadController by following command: 

php artisan make:controller FileUploadController

app/Http/Controllers/FileUploadController.php 

<?php

  
namespace App\Http\Controllers;

   
use Illuminate\Http\Request;

  
class FileUploadController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('fileUpload');
    }

    
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $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 : Add Routes

routes/web.php 

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

Step 4: Add Blade File

                </div>
            @endif

      
            <form action="{{ route('file.store') }}" method="POST" enctype="multipart/form-data">
                @csrf

      
                <div class="mb-3">
                    <label class="form-label" for="inputFile">Select 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>

      
        </div>
    </div>
</div>
</body>
</html>
