php - 如何在 laravel Blade View 上定义变量数组？

Question

我这样尝试:

<div class="media-body">
    @foreach($categories as $category)
    @php $category[] = $category->name @endphp
    @endforeach   
    {{ implode(",", $category) }}
</div>

如果执行代码，存在错误:

undefine variable category

我该如何解决？

Answer 1

你可以简单地使用 Laravel 集合

{{ $categories->pluck('name')->implode(', ') }}

或者如果你想在 foreach 中这样做

@php ($names = [])

@foreach ($categories as $category)
    @php ($names[] = $category->name)
@endforeach

{{ implode(', ', $names) }}
