Can't validate input file in laravel

Question

I want to validate a file input but the validation does not work it always return The given data was invalid. even if the file given meets the validation requirements knowing that I'm uploading multiple files at once:

Here's the validation I use :

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

And here's the HTML I use :

<input type="file" id="files" ref="files" multiple v-on:change="uoloadFiles()" name="files"/>

Knowing that I use vue to handle the form submission.

Thanks for helping

I think this is since you are uploading multiple files at once, which makes `files` an array, not a single file. Not enough information given in the question to verify that. — Imesha Sudasingha, Apr 20 '18 at 02:40
You will need something like [this](https://laravel.com/docs/5.6/validation#validating-arrays) — Imesha Sudasingha, Apr 20 '18 at 02:43

This should work since you are uploading multiple files, each file should be validated separately.

Validator::make($request->all('files'), [
    'files.*' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048'
])->validate();

Note the *.

if you have only this field you can do:

Validator::make($request->only('files'), [
    'files.*' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048'
])->validate();

otherwise use all method without arguments:

 Validator::make($request->all(), [
      'files.*' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048'
 ])->validate();
