public function home(Request $request)
{
$surveys = Survey::get();
$user_id = auth()->user()->id; // you don't need to iterate over and over again for the same value
$user_ip = request()->ip(); // you don't need to iterate over and over again for the same value
foreach ($surveys as $survey) {
$hasAnswer[] = \App\Answer::where(['user_id'=>$user_id , 'survey_id' => $survey->id, 'last_ip'=>$user_ip])->exists();
}
return view('home', compact('surveys','hasAnswer'));
}
blade file:
<div class="col-12">
<ul class="list-group">
#forelse ($surveys as $key => $survey)
#if($hasAnswer[$key])
<li class="list-group-item list-group-item-success">
<div>
{{ link_to_route('detail.survey', $survey->title, ['id'=>$survey->id])}}
<i class="material-icons">send</i>
<i class="material-icons">edit</i>
<i class="material-icons">textsms</i>
</div>
</li>
#else
<li class="list-group-item">
<div>
{{ link_to_route('detail.survey', $survey->title, ['id'=>$survey->id])}}
<i class="material-icons">send</i>
<i class="material-icons">edit</i>
<i class="material-icons">textsms</i>
</div>
</li>
#endif
#empty
<p class="flow-text center-align">Nothing to show</p>
#endforelse
</ul>
</div>
