Laravel检查Array是否为空

Question

我正在努力显示一些内容,具体取决于数组属性是否具有值.如果文章有标题,我想显示整篇文章的内容,如果不是,我想展示其他内容.但是,它不起作用.else语句中的代码未执行.

这有什么不对？

我的代码是:

@foreach($restaurantmenue as $daily)
                    @foreach($daily->articles as $menue)
                     @if(!empty($menue->title))
                       <div class="card card-horizontal">
                         <div class="row">
                           <div class="col-md-5">
                             <div class="image" style="background-image: url({{asset('images/frontend/profile/profileHero.jpg')}}); background-size: cover; background-position: center center;">
                               <img src="{{asset('images/frontend/profile/profileHero.jpg')}}" alt="..." style="display: none;">
                               <div class="filter filter-azure">
                                 <button type="button" class="btn btn-neutral btn-round">
                                     <i class="fa fa-heart"></i> SMÄCKT MIR

                             </div>
                           </div>
                           <div class="col-md-7">
                                <div class="content">

如果你在laravel中使用ORM获取数据

$data = \App\Model::get();

然后你可以检查是否$data为空,如下:

@if(!$data->isEmpty())
     // $data is not empty
@else
    // $data is empty
@endif

参考:检查这里

但是,如果你使用find或findOrFail,那么你可以检查数组

$data = \App\Model::findOrFail($id);


@if(!empty($data))
     // $data is not empty
@else
    // $data is empty
@endif
