Save options radios or checkbox - laravel

Question

I want to save radio from form in database but I get "on" in the database, I don't know why.
I tried to use HTML form with labels, radios and checkbox but I see in the database saving "on".
Controller :
public function store(Request $request, Survey $survey)
{
// remove the token
$arr = $request->except('_token');
foreach ($arr as $key => $value) {
$newAnswer = new Answer();
if (! is_array( $value )) {
$newValue = $value['answer'];
} else {
$newValue = json_encode($value['answer']);
}
$newAnswer->answer = $newValue;
$newAnswer->question_id = $key;
$newAnswer->user_id = Auth::id();
$newAnswer->survey_id = $survey->id;
$newAnswer->save();
$answerArray[] = $newAnswer;
};
return redirect()->action('SurveyController#view_survey_answers', [$survey->id]);
}
view :
{!! Form::open(array('action'=>array('AnswerController#store', $survey->id))) !!}
#forelse ($survey->questions as $key=>$question)
<p class="flow-text">Question {{ $key+1 }} - {{ $question->title }}</p>
#if($question->question_type === 'text')
<div class="input-field col s12">
<input id="answer" type="text" name="{{ $question->id }}[answer]">
<label for="answer">Answer</label>
</div>
#elseif($question->question_type === 'textarea')
<div class="input-field col s12">
<textarea id="textarea1" class="materialize-textarea" name="{{ $question->id }}[answer]"></textarea>
<label for="textarea1">Textarea</label>
</div>
#elseif($question->question_type === 'radio')
#foreach($question->option_name as $key=>$value)
<p style="margin:0px; padding:0px;">
<input name="{{ $question->id }}[answer]" type="radio" id="{{ $key }}" />
<label for="{{ $key }}">{{ $value }}</label>
</p>
#endforeach
#elseif($question->question_type === 'checkbox')
#foreach($question->option_name as $key=>$value)
<p style="margin:0px; padding:0px;">
<input type="checkbox" id="something{{ $key }}" name="{{ $question->id }}[answer]" />
<label for="something{{$key}}">{{ $value }}</label>
</p>
#endforeach
#endif
<div class="divider" style="margin:10px 10px;"></div>
#empty
<span class='flow-text center-align'>Nothing to show</span>
#endforelse
{{ Form::submit('Submit Survey', array('class'=>'btn waves-effect waves-light')) }}
{!! Form::close() !!}

You forgot to give a value attribute to your checkbox and radio inputs, for example something like this:
<input name="{{ $question->id }}[answer]" type="radio" id="{{ $key }}" value="{{ $key}}"/>
<input type="checkbox" id="something{{ $key }}" name="{{ $question->id }}[answer]" value="{{ $key}}"/>
