Image Validation Rules

Laravel 12 Image Validation Rules Example

In this post, I will show you how to use image validation rules in laravel 12 application. laravel provides default image validation rules like image, mimes, max, min and dimensions.

Using Laravel default 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:

Step 1: Install Laravel 12

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 ImageController; in this file, we will add two method index() and store() for render view and store image logic.

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); 
    }
}

Step 3: Create Routes

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

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\ImageController;
  
Route::controller(ImageController::class)->group(function(){
    Route::get('image-upload', 'index');
    Route::post('image-upload', 'store')->name('image.store');
});

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
