如何將所有類別和子類別傳遞給布局 laravel 9

Question

我是開發新手，我遇到了一個問題，我無法在“layout.app”中顯示所有子類別對於每個類別，只顯示一個子類別，我需要獲取所有子類別

在文件 AppServiceProvider.php 中

 
public function boot()
{
    view()->composer('layout.app', function ($view){
        $view->with('categories', Category::with('subcategories')->get());
    });
}

in layout.app
<ul class="sub-category">
    @foreach($categories as $category)
    <li>
        <a href="{{ url('products') }}">{{ $category->title }}
            <i class="lni lni-chevron-right"></i>
        </a>
        @foreach($category->subcategories as $subcategory)
        <ul class="inner-sub-category">
            {{ $subcategory['title'] }}
        </ul>
        @endforeach
    </li>
    @endforeach
</ul>

Answer 1

我假設您正在接收所有數據。

對於子數組，您需要在foreach循環之外定義<ul> 。

<ul class="inner-sub-category"> // Moved outside the foreach loop
    @foreach($category->subcategories as $subcategory)
        <li>{{ $subcategory['title'] }}</li>
    @endforeach
</ul>
