如何验证mimes文件laravel

Question

So I'm trying to validate the uploaded image to be only of this type mimes: jpeg, jpg, png but the problem is if I put the code like this:

'photos' => 'required|array|max:5|mimes:jpeg,jpg,png',
'photos.*' => 'mimes:jpeg,jpg,png', 

It validates as expected like this The image must be a file of type:jpg,jpeg,png only, but even if I upload the jpg or png file still shows The image must be a file of type:jpg,jpeg,png only. And if I put the code like this:

'photos' => 'required|array|max:5',
'photos.*' => 'mimetypes:image/jpeg,image/png,image/jpg',

It does not validate so I can even upload a video, psd, and other files which are not of this type mimes:jpeg,jpg,png . How can I validate the uploaded file to be only of this type mimes:jpeg,jpg,png?

Controller

$this->validate(
    $request, 
    [
    'photos' => 'required|array|max:5',
    'photos.*' => 'mimetypes:image/jpeg,image/png,image/jpg',
    ]
);

Answer 1

this is correction from your code

'photos' => 'required|array|max:5'
'photos.*' => 'mimes:jpeg,jpg,png',

and make sure you put enctype="multipart/form-data" in your form like this

<form action url enctype="multipart/form-data">

this made browser actually send file(s) to server (view to controller),

then mimes can recognize/catch the file extension you sent from browser

this might explain better from laravel documentation Laravel validation rules
