php - validation value having two possible types -

-

how validate request value when should string or array both valid?

'val' => 'bail|required|string' 'val' => 'bail|required|array'

what the validation expression?

i don't think there way achieve using validation rules out of box. need use custom validation rules achieve this:

in appserviceprovider's boot method, add in

public function boot() {     validator::extend('string_or_array', function ($attribute, $value, $parameters, $validator) {         return is_string($value) || is_array($value);     }); }

then can start using it:

'val' => 'bail|required|string_or_array'

optionally can set custom validation error messages, or using custom validation class achieve it. check out doc link above more information.
