Upload field minimum files/images

Need Help
#1

Hi! is there a way to require a minimum amount of files/images to be uploaded in the fileupload field? There is maxFiles… but I’d need also “minFiles”.
I already thought of making multiple upload fields, but I’d like to keep it as one field and the client be able to drag reorder them. I know I can do that with a repeater of single fileuploads… but I think it’s overkill. I’d like to keep the UI simpler.

Here a solution (to put in your model):

public function beforeSave() {

        $sessionKey = \Input::get('_session_key');

        $files = $this->files()->withDeferred($sessionKey)->get();

        if ($files->count() < 2) {
            throw new \ApplicationException('Add at least 2 files.');
        }
}

Replace “files()” with your relation.

In latest version, you can use the between rule definition too:

public $rules = [
    'files' => 'required|between:1,2',
];
