Laravel检查空数组 [英] Laravel Check Empty Array

问题描述

在laravel中检查数组是否为空还是很麻烦.

I still have trouble with checking if an array is empty or not in laravel.

这是我的观点:

@foreach($restaurantmenue as $daily)

                    @if(empty($daily->articles))
                      no article
                      @else
                        @foreach($daily->articles as $menue)
                            <a class="card-link" href="#">
                                <h4 class="title">{{$menue->title}} </h4>
                            </a>
                       @endforeach
                    @endif


                @endforeach

{{dd($ daily-> articles}}} 当我查看我的视图时(一个带有文章，另一个不带有文章)，我得到以下输出:

{{dd($daily->articles)}} When I check my views (One with an Article and the other without an article) I get this output:

具有现有文章的视图显示: 集合{#228▼ #项:array:1 [▶] }

The View with an existing article shows: Collection {#228 ▼ #items: array:1 [▶] }

没有文章的视图显示: 集合{#227▼ #项目: [] }

And the view without an article shows: Collection {#227 ▼ #items: [] }

我不知道为什么IF STATEMENT中的代码没有执行.不显示无文章"消息.

I have no idea why the code in the IF STATEMENT is not executed. The "No Article" Message is not displayed.

推荐答案

由于它是Laravel集合，因此可以使用 isEmpty() 助手:

Because it's Laravel collection, you can use isEmpty() helper:

@if($daily->articles->isEmpty())
