Laravel 圖片上傳＆驗證方便到爆炸

找到一篇文章，才知道有這種寫法

https://hdtuto.com/article/laravel-57-image-upload-with-validation-example

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

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

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

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

@if (count($errors) > 0)
    <div class="alert alert-danger">
        <strong>上傳失敗！</strong>檔案出現以下問題：
        <ul class="mb-0">
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif

才短短幾行，上傳、驗證、搬檔案通通都做到了
