Laravel 10 Image Validation Rule Example

Hello Artisan, today I'll show you Image Validation Rule Example laravel application. This tutorial will give you an example of laravel 10 image validation rules. In Laravel 10, you can easily validate image sizes. There's also a helpful article on image validation mimes in Laravel 10. Below, we'll explore an example of how to validate image width and height.

Laravel 10 comes with default image validation rules to ensure user-provided images meet the required criteria.

  • image
  • mimes
  • dimensions
  • max

using above validation rules you can set file type like "jpg,png,jpeg,gif,svg", using max you can set limit of file size. using dimensions you can set file height and width limit. so, let's see the following simple example code:

  4. Create Blade File
  5. Output

Install Laravel 10 App

Creating the Laravel app is not necessary for this step, but if you haven't done it yet, you can proceed by executing the following command

composer create-project laravel/laravel image-validation

Create Controller

In this next step, we'll be generating a fresh ImageController. Inside this file, we'll implement two methods: index() and store(). The index() method will be responsible for rendering the view, while the store() method will handle the logic for storing the image.

Let's create ImageController by following command:

php artisan make:controller ImageController

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

app/Http/Controllers/ImageController.php
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;

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

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request): RedirectResponse
    {
        $this->validate($request, [
            'image' => ['required',
                'image',
                'mimes:jpg,png,jpeg,gif,svg',
                'dimensions:min_width=100,min_height=100,max_width=1000,max_height=1000',
                'max:2048'],
        ]);

        $imageName = time().'.'.$request->image->extension();

        $request->image->move(public_path('images'), $imageName);

        /*
            Write Code Here for
            Store $imageName name in DATABASE from HERE
        */

        return back()
            ->with('success', 'You have successfully upload image.')
            ->with('image', $imageName);
    }
}

Create and Add Routes

To set up routes for handling GET and POST requests to render views and store images, follow these steps:

Open the routes/web.php file in your project.

Add the following code to manage the GET request for rendering the view:

routes/web.php
<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\ImageController;

/*
|--------------------------------------------------------------------------
| 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::controller(ImageController::class)->group(function(){
    Route::get('image-upload', 'index');
    Route::post('image-upload', 'store')->name('image.store');
});

Create Blade File

Finally, we need to create an imageUpload.blade.php file with a form that includes a file input button.

So copy bellow and put on that file

resources/views/imageUpload.blade.php
<!DOCTYPE html>
<html>
<head>
    <title>Laravel 10 Image Upload Example</title>
    <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
</head>

<body>
<div class="container">

    <div class="panel panel-primary">

        <div class="panel-heading">
            <h2>Laravel 10 Image Upload Example</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">ร—</button>
                    <strong>{{ $message }}</strong>
                </div>
                <img src="images/{{ Session::get('image') }}">
            @endif

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

                <div class="mb-3">
                    <label class="form-label" for="inputImage">Image:</label>
                    <input
                        type="file"
                        name="image"
                        id="inputImage"
                        class="form-control @error('image') is-invalid @enderror">

                    @error('image')
                    <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>

Output:

To run the Laravel app, simply type the following command and press Enter:

php artisan serve

Now, Go to your web browser, type the given URL and view the app output:

http://localhost:8000/image-upload

That's it for today. I hope it'll be helpful in upcoming project. You can also download this source code from GitHub. Thanks for reading. ๐Ÿ™‚
