如何实现块

Question

我不是很有经验，而且遇到问题。我无法弄清楚如何使这个函数使用块。尝试所有，但得到错误，我认为我误解了一些东西。

$companies_has = Company::whereHas('websites', function ($q) { 
     $q->where('updated_at', '<=', Carbon::now()->subMonth()); 
    })->get(); 
    $companies_doesnt_has = Company::whereDoesntHave('websites')->get(); 
    $companies = $companies_has->merge($companies_doesnt_has); 
    foreach ($companies as $company) { 
    $this->getWebsite($company); } 

Answer 1

@foreach ($companies->chunk(3) as $chunk) 
    <div class="row"> 
     @foreach ($chunk as $product) 
      <div class="col-xs-4">{{ $product->name }}</div> 
     @endforeach 
    </div> 
@endforeach
