Laravel - 未定义的变量：文章

Question

public function press (Request $request)
{
    if($request->has('search')){
        $articles =  Press::search($request->input('search'))->get();
    }
    return view('pages.press.index', compact('articles'));
}

I'm receiving an error Undefined variable: articles. Above is the code I'm using in my controller. What is the error that I'm making?

 @if(!empty($articles))
    @foreach ($articles as $article)
      <div class="col-md-4">
        <div class="box border">
          <div class="box-header">
            <a href="{{ url('/press/'.$article->slug) }}"><img src="{{ url('http://assets.hobohweb.com/uploads/press/'.$article->image) }}" class="img-fluid" alt=""></a>

            {{ Carbon\Carbon::parse($article->created_at)->diffForHumans() }} on <a href="{{ url($article->source_url) }}" class="text-primary">{{ $article->source }}</a>
          </div>
        </div>
      </div>
    @endforeach
  @endif

Just check if there are any articles in your search, like:

if($request->has('search')){
    $articles =  Press::search($request->input('search'))->get();
} else {
    $articles = [];
}

And use it in the view:

@forelse($articles as $article)
    ...
@empty
    <p>There are no articles!</p>
@endforelse
