php - 尝试在前端 Laravel 6 中设置默认类别视图

Question

我完全是 Laravel 的业余爱好者，我正在尝试找到一种方法来默认显示特定类别及其服务，而不是显示所有现有类别的所有服务。

<section class="categories sp-80-50 bg-dull">
        <div class="container">
            <div class="row">
                <div class="col-12">
                    <div class="all-title">
                        <p>@lang('front.categoriesTitle')</p>
                        <h3 class="sec-title">
                            @lang('front.categories')
                        </h3>
                    </div>
                </div>
            </div>
            <div id="categories" class="row justify-content-center">
               
                @foreach ($categories as $category)
                    @if($category->services->count() > 0)
                    <div class="col-xl-2 col-lg-3 col-md-4 col-sm-6 col-12 mb-30 categories-list" data-category-id="{{ $category->id }}">
                        <div class="ctg-item" style="background-image:url('{{ $category->category_image_url }}')">
                            <a href="javascript:;">

                                        {{ ucwords($category->name) }}
                                    </h5>
                                </div>
                            </a>
                        </div>

                @endforeach
            </div>
        </div>
    </section> */

我需要为第一个按钮类别设置默认服务视图。

抱歉，如果我的问题很愚蠢或解决方案很简单，但我不知道该怎么做！

您的错误是您永远不会遍历该类别的服务。

您检查是否有任何服务，但您永远不会遍历它们。所以，在@if你应该这样做。

@foreach ($categories as $category)
    @if($category->services->count() > 0)
        @foreach($category->services as $service)
         // your code
        @endforeach
    @endif
@endforeach
