如何在laravel刀片视图上定义变量数组？

Question

我试着这样:

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

如果代码执行,则存在错误:

取消定义变量类别

我该如何解决？

Answer 1

您只需使用Laravel Collection即可

{{ $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) }}
