laravel foreach input radiobutton displayed incorrectly

I’m trying to display the options for the questions. i have the problem that when im doing it this way:

@section('content')
<div class="card">
  <div class="card-header">Quiz: {{$category->name}}:</div>
  <div class="card-body">
    <form action="#" method="post" class="form-group">
      @csrf
      @foreach($questions as $key => $question)
        <div class="form-group">
          <label for="question">Question {{1+$key}}:</label>
          <p class="card-text">{{$question->question_text}}</p>
          @foreach($question->option_text as $key => $option)
            <input type="radio">{{$option}}
          @endforeach
        </div>
        @endforeach
      <div class="form-group">
        <input type="submit" class="btn btn-primary">
      </div>
    </form>
  </div>
</div>
@endsection

i can check all radio buttons at the same time but if i put there a name for the radiobutton i can check only one of the options for the whole questions.. i think there’s something strange with the foreach loop..

Info: the table “questions” has the following rows: id, category_id, question_text, correct_answer, option_text (this is a json-field that is casted to an array)

Code from Controller:

public function store(Request $request, Category $category){
  if($request->categoryTest == $category->name){
    $questions = $category->question()->inRandomOrder()->get();
    return view('user.test', compact('questions', 'category'));
  }
}

do you have an idea how to fix this? thank you!

Try this:

@section('content')
<div class="card">
  <div class="card-header">Quiz: {{$category->name}}:</div>
  <div class="card-body">
    <form action="#" method="post" class="form-group">
      @csrf
      @foreach($questions as $key => $question)
        @php
        $q = 1+$key
        @endphp
        <div class="form-group">
          <label for="question">Question {{1+$key}}:</label>
          <p class="card-text">{{$question->question_text}}</p>
          @foreach($question->option_text as $key => $option)
            <input name="radio-{{$q}}" type="radio">{{$option}}
          @endforeach
        </div>
        @endforeach
      <div class="form-group">
        <input type="submit" class="btn btn-primary">
      </div>
    </form>
  </div>
</div>
@endsection
