Its because I am putting the validation inside loop and not use * character to validate an array

...
for ($i=0; $i < $count ; $i++) {
   ...
   $this->validate($request, [
      'value['.$i.']' => 'max:30'
   ]);
   ...
   // save etc
}

right code, put validation before loop, and use * character for array validation :

$this->validate($request, [
      'value.*' => 'max:30'
]);
...
for ($i=0; $i < $count ; $i++) {
   // save etc
}

The Controller::validate() is not a generic validation method, it validates requests. For this use case, simply use the validator directly:

Validator::make($data, ['value' => 'max:30']);

The error message is telling you what’s wrong:

Argument 1 passed to App\Http\Controllers\Controller::validate() must be an instance of Illuminate\Http\Request, array given

So pass the Request instance to the validate() method:

public function store(Request $request)
{
    $this->validate($request, [
        'value.*' => 'max:30',
    ]);
}
