Today now in this blog, I will show you how to image validation in laravel application. The file need to under validation must be an image as like jpeg, png, bmp, gif, svg, or webp type.

So we can easily validate images in Laravel application like file max size or mini size and lots of new validation option as image dimension for image upload in server.

So the file validation in file size to validate the file in laravel application. Now in case of string, it validates the length in characters. So now we need to a new validation option: image dimensions for image uploads. Now the validation rule is called dimensions.

So here is a solution and now i also give you full example also with route and view file too. Let’s start and see bellow solution :

Solution
public function solution(Request $request)
{
    $request->validate([
        'image' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048|dimensions:min_width=100,min_height=100,max_width=1000,max_height=1000',
    ]);

}

Route: routes/web.php

Route::get('image','FrontHomeController@image');
Route::post('image-store','FrontHomeController@imageStore')->name('image.store');

Controller : app/Http/controllers/FrontHomeController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FrontHomeController extends Controller
{
    public function image()
    {
        return view('image');
    }

    public function imageStore(Request $request)
    {
        $request->validate([
            'image' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048|dimensions:min_width=100,min_height=100,max_width=1000,max_height=1000',
        ]);
        return redirect()->back();

    }
}
