php - 如何在 Laravel 中显示所有类别

Question

我试图在单个帖子刀片上显示数据库中的所有类别，但是，我也将数据库中的五个类别显示为我的导航菜单。我不确定它是否是我正在使用的循环，因为我不断获得五个类别而不是所有类别。

public function index()
{
    return view('index')->with('title', Setting::first()->site_name)
        ->with('categories', Category::take(5)->get())
        ->with('first_post', Post::orderBy('created_at', 'desc')->first())
        ->with('second_post', Post::orderBy('created_at', 'desc')->skip(1)->take(1)->get()->first())
        ->with('third_post', Post::orderBy('created_at', 'desc')->skip(2)->take(1)->get()->first())
        ->with('wordpress', Category::find(4))
        ->with('laravel', Category::find(3))
        ->with('settings', Setting::first());
}

这是我的单后控制器的代码

public function singlePost($slug)
{
    $post = Post::where('slug', $slug)->first();
    $next_id = Post::where('id', '>', $post->id)->min('id');
    $prev_id = Post::where('id', '<', $post->id)->max('id');

    return view('single')->with('post', $post)
        ->with('title', $post->title)
        ->with('settings', Setting::first())
        ->with('categories', Category::all())
        ->with('next', Post::find($next_id))
        ->with('prev', Post::find($prev_id))
        ->with('tags', Tag::all())
        ->with('first_post', Post::orderBy('created_at', 'desc')->first())
        ->with('second_post', Post::orderBy('created_at', 'desc')->skip(1)->take(1)->get()->first())
        ->with('third_post', Post::orderBy('created_at', 'desc')->skip(2)->take(1)->get()->first());
}

这就是我在 single.blade.php 中传递值的方式

@foreach($categories as $category)
    <div class="post-category-wrap">
        <div class="category-post-item">
            <!-- <span class="post-count">168</span> -->
            <a href="{‌{route('category.single', ['id' => $category->slug])}}" class="category-title">{‌{$category->name}}
                <i class="seoicon-right-arrow"></i>
            </a>
        </div>
    </div>
@endforeach

我认为您应该在“类别”的索引查询中更改 var 名称。类似的东西 ->with('categories_to_navigation', Category::take(5)->get())。如果视图single.blade.php扩展index.blade.php此 var 名称将被覆盖。
