Step 1 : Install Laravel 8

First of all, we need to get fresh laravel 8 version application using bellow command because we are going from scratch, So open your terminal OR command prompt and run bellow command:

composer create-project --prefer-dist laravel/laravel blog

Step 2: Create Routes

In next step, we will add new two routes in web.php file. One route for generate form and another for post method So let's simply create both route as bellow listed:

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\ImageUploadController;
  
  
Route::get('image-upload', [ ImageUploadController::class, 'imageUpload' ])->name('image.upload');
Route::post('image-upload', [ ImageUploadController::class, 'imageUploadPost' ])->name('image.upload.post');


Step 3: Create ImageUploadController

In third step we will have to create new ImageUploadController and here we have to write two method imageUpload() and imageUploadPost(). So one method will handle get method another one for post. So let's add code.

app/Http/Controllers/ImageUploadController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
  
class ImageUploadController extends Controller
{
     /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function imageUpload()
    {
        return view('imageUpload');
    }
    
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function imageUploadPost(Request $request)
    {
        $request->validate([
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        ]);
    
        $imageName = time().'.'.$request->image->extension();  
     
        $request->image->move(public_path('images'), $imageName);
  
        /* Store $imageName name in DATABASE from HERE */
    
        return back()
            ->with('success','You have successfully upload image.')
            ->with('image',$imageName); 
    }
}

Store Image in Storage Folder

$request->image->storeAs('images', $imageName);
  
// storage/app/images/file.png

Store Image in Public Folder

$request->image->move(public_path('images'), $imageName);
  
// public/images/file.png

Store Image in S3

$request->image->storeAs('images', $imageName, 's3');

Step 4: Create Blade File

At last step we need to create imageUpload.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/imageUpload.blade.php

<!DOCTYPE html>
<html>
<head>
    <title>laravel 8 image upload example - ItSolutionStuff.com.com</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">

<body>
<div class="container">
     
    <div class="panel panel-primary">
      <div class="panel-heading"><h2>laravel 8 image upload example - ItSolutionStuff.com.com</h2></div>
      <div class="panel-body">
     
        @if ($message = Session::get('success'))
        <div class="alert alert-success alert-block">
            <button type="button" class="close" data-dismiss="alert">×</button>
                <strong>{{ $message }}</strong>
        </div>
        <img src="images/{{ Session::get('image') }}">
        @endif
    
        @if (count($errors) > 0)
            <div class="alert alert-danger">
                <strong>Whoops!</strong> There were some problems with your input.
                <ul>
                    @foreach ($errors->all() as $error)
                        <li>{{ $error }}</li>
                    @endforeach
                </ul>
            </div>
        @endif
    
        <form action="{{ route('image.upload.post') }}" method="POST" enctype="multipart/form-data">
            @csrf
            <div class="row">
    
                <div class="col-md-6">
                    <input type="file" name="image" class="form-control">
                </div>
     
                <div class="col-md-6">
                    <button type="submit" class="btn btn-success">Upload</button>
                </div>
     
            </div>
        </form>
    
      </div>
    </div>
</div>
</body>
  
</html>

Now you can run and check it.
