There is a beautiful validation rule class in laravel for validating images. In this tutorial, we will validate an image type that should be image and then we will validate image extension like the image must be a png file or jpg file like that.
File rule class gives us a method called types and using them we can pass a collection of file types that we want to accept to upload to the server. Let's see the error message of laravel image extension validation:
Now we will see how to validate file extension in laravel? Let's see the example code of laravel image validation must be an image.
app/Http/Controllers/TutorialController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Validation\Rule;
use Illuminate\Validation\Rules\File;
use Illuminate\Support\Facades\Validator;
class TutorialController extends Controller
{
public function index()
{
return view('welcome');
}
public function store(Request $request)
{
Validator::validate($request->all(), [
'image' => [
'required',
File::image()
->types(['png', 'jpg', 'jpeg'])
]
]);
}
}
If the uploaded file is not an image, then validate the extension like the below:
app/Http/Controllers/TutorialController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Validation\Rules\File;
use Illuminate\Support\Facades\Validator;
class TutorialController extends Controller
{
public function index()
{
return view('welcome');
}
public function store(Request $request)
{
Validator::validate($request->all(), [
'attachment' => [
'required',
File::types(['mp3', 'mp4'])
->min(1024)
->max(12 * 1024),
]
]);
}
}
Now show the error message in your blade file like:
resources/views/welcome.blade.php
@extends('layouts.app')
@section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
