Hi Dev,

In this Tutorial,I will share you how to utilize image with grayscale in laravel 8. We will show example of image with grayscale in laravel 8. Spatie package is Image manipulation doesn't have to be hard. This PHP package makes it super easy to apply prevalent manipulations to images like resizing, cropping and integrating effects.

Here, I will show you full example for simply image with grayscale using Laravel 8 as bellow,So follow my steps.

Step 1 : Install Laravel 8 Application

First of all in this first step we are going from scratch, So we need to get fresh Laravel application using bellow command, So open your terminal OR command prompt and run bellow command:

composer create-project --prefer-dist laravel/laravel blog
Step 2 : Install Spatie Package

In this second step, we will install spatie package for bellow command.

composer require spatie/image
Step 3: Create Routes

In this third step, i will integrate new two routes in web.php file. One route for generate image upload form and another for post method So let's simply engender both route as bellow listed:

<?php
use App\Http\Controllers\GrayscaleController;
use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| 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('/image/grayscale', [GrayscaleController::class, 'index'])->name('image.grayscale.index');
Route::post('/image/grayscale/store', [GrayscaleController::class, 'grayscalStore'])->name('image.grayscale.store');
Step 4: Create Controller

Here,in this step now we should engender new controller as GrayscaleController,So run bellow command for generate new controller

php artisan make:controller GrayscaleController
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Image;

class GrayscaleController extends Controller
{
     /**
       * Write code on Method
       *
       * @return response()
     */
    public function index()
    {
      return view('imageWithgrayscale');
    }

    /**
     * Write code on Method
     *
     * @return response()
     */
    public function grayscalStore(Request $request)
    {
      $input = $request->all();

      $this->validate($request, [
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        ]);

        $image = $input['image'];
        
        $input['image'] = time().'.'.$image->getClientOriginalExtension();

        $img = Image::make($image->getRealPath());

        $img->grayscale()->save(public_path('/images').'/'.$input['image']);

        return redirect()->back()->with('success','Image Uploaded Successfully')->with('image',$input['image']);
    }
}
Step 5: Create Blade File

At last step we require to engender imageWithgrayscale.blade.php file. So copy bellow and put on that file.

<!DOCTYPE html>
<html>
<head>
  <title>Grayscale Image Uploading Demo - MyWebTuts.com</title>
</head>
<body>
<div class="container">
  <div class="row mt-5">
    <div class="col-md-6 offset-md-3 mb-3">
      <h2>Grayscale Image Uploading Demo - MyWebTuts.com</h2>

      @if (count($errors) > 0)
        <div class="alert alert-danger">
          <ul>
            @foreach ($errors->all() as $error)
              <li>{{ $error }}</li>
            @endforeach
          </ul>
        </div>
      @endif

      @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>
        <div class="row">
          <div class="col-md-12">
            <strong>Grayscale Image:</strong><br/>
            <img src="/images/{{ Session::get('image') }}" width="500px" />
          </div>
        </div>
      @endif
      {!! Form::open(array('route' => 'image.grayscale.store','enctype' => 'multipart/form-data')) !!}
        <div class="row">
          <div class="col-md-12">
            <div class="form-group">
              <strong>Image:</strong>
              {!! Form::file('image', array('class' => 'form-control image')) !!}
            </div>
          </div>
          <div class="col-md-12 text-center">
            <button type="submit" class="btn btn-success">Upload Image</button>
          </div>
        </div>
      {!! Form::close() !!}
    </div>
  </div> 
</div>
</body>
</html>

Now we are ready to run our custom validation rules example so run bellow command for quick run:

php artisan serve

Now you can open bellow URL on your browser:
