在 laravel 中创建嵌套评论

Question

我有以下博客控件

public function show($slug)
{
    $post = Blog::where('slugs', '=', $slug)->first();

    $vars['pageTitle'] = Config::get('site.pageTitle') . $post['title'];

    // The breadcrumbs... needs to be repopulated every page
    $vars['breadCrumbs'] = [[
        'url'   => action('SimpleController@index'),
        'title' => 'CovertDEV'
    ],[
        'url'   => action('BlogController@index'),
        'title' => 'Blog'
    ],[
        'url'   => route('blog_post', ['slug' => $slug]),
        'title' => $post['title']
    ]];

    $vars['blog'] = $post;

    $vars['comments'] = $post->Blog_comments->groupBy('comment_id');

    return view('blog', $vars);
}

还有下面吓人的观点求评论

@php
function display_comments($main, $depth = "\t")
{
    foreach($main[0] as $mcomment)
    {
@endphp
                                <div class="media">
                                    <img class="m-3 avatar-sm rounded-1 border border-thick-1 shadow" src="../public/css/images/avatar-placeholder.png" alt="<?=$mcomment->firstname;?> <?=$mcomment->lastname;?>'s Avatar">
                                    <div class="media-body">
                                        <h6 class="mt-0 p-1 lead m-0 border-bottom"><?=$mcomment->firstname;?> <?=$mcomment->lastname;?></h6>
                                          <div class="p-2">
                                            <p><?=$mcomment->comment;?></p>
                                        </div>
@php
        if(isset($main[$mcomment->id]))
        {
            display_child($main, $main[$mcomment->id], $depth);
        }
@endphp
                                    </div>
                                </div>
@php
    }
}

function display_child($main, $comment, $depth)
{
    foreach($comment as $ccomment)
    {
@endphp
                                        <div class="media">
                                            <img class="m-3 avatar-sm rounded-1 border border-thick-1 shadow" src="../public/css/images/avatar-placeholder.png" alt="<?=$ccomment->firstname;?> <?=$ccomment->lastname;?>'s Avatar">
                                            <div class="media-body">
                                                <h6 class="mt-0 p-1 lead m-0 border-bottom"><?=$ccomment->firstname;?> <?=$ccomment->lastname;?></h6>
                                                <div class="p-2">
                                                    <p><?=$ccomment->comment;?></p>
                                                </div>
@php
        if(isset($main[$ccomment->id]))
        {
            display_child($main, $main[$ccomment->id], $depth."\t");
        }
@endphp
                                            </div>
                                        </div>
@php

    }
}

display_comments($comments);

@endphp

这太丑陋了。它生成了我想要的样子，但这太丑了，丑得可怕。

在 blade 模板中优雅地完成这项工作的最佳方法是什么？我尝试根据 docs 扩展 blade 模板，但这对我来说并没有取得成果。我根本不知道该怎么做。

有了这个，我不能调用资产或类似的东西......那些已经超出了范围。

我终于找到了令我满意的解决方案。如果大家有更好的解决方案，欢迎提出。

我的博客控制器是一样的，唯一改变的是我的视图。在我的博客视图中（我以用户身份看到这些评论）：

blog.blade.php

@foreach($comments[0] as $comment)
<div class="media comment">
@if(!is_null($comment->users['avatar']))
    <img class="m-3 avatar-sm rounded-1 border border-thick-1 shadow" src="{{ asset( Config::get('site.asset_folder') . 'users/images/' . $comment->users['avatar']) }}" alt="{{ $comment->users['firstname'] }} {{ $comment->users['lastname'] }}'s Avatar">
@else
    <img class="m-3 avatar-sm rounded-1 border border-thick-1 shadow" src="{{ asset( Config::get('site.asset_folder') . 'css/images/avatar-placeholder.png') }}" alt="{{ $comment->users['firstname'] }} {{ $comment->users['lastname'] }}'s Avatar">
@endif
    <div class="media-body">
        <h6 class="mt-0 p-1 lead m-0 border-bottom">{{ $comment->users['firstname'] }} {{ $comment->users['lastname'] }}</h6>
          <div class="p-2">
            <p>{{ $comment->comment }}</p>
        </div>
@if(isset($comments[$comment->id]))
    @include('block.comments', ['comments' => $comments, 'parent_id' => $comment->id, 'depth' => 0])
@endif
    </div>
</div>
@endforeach

然后，我的block/comments.blade.php

@foreach($comments[$parent_id] as $comment)
@if($depth >= Config::get('site.max_nested'))
    </div>
</div>

@endif
<div class="media comment">
@if(!is_null($comment->users['avatar']))
    <img class="m-3 avatar-sm rounded-1 border border-thick-1 shadow" src="{{ asset( Config::get('site.asset_folder') . 'users/images/' . $comment->users['avatar']) }}" alt="{{ $comment->users['firstname'] }} {{ $comment->users['lastname'] }}'s Avatar">
@else
    <img class="m-3 avatar-sm rounded-1 border border-thick-1 shadow" src="{{ asset( Config::get('site.asset_folder') . 'css/images/avatar-placeholder.png') }}" alt="{{ $comment->users['firstname'] }} {{ $comment->users['lastname'] }}'s Avatar">
@endif
    <div class="media-body">
        <h6 class="mt-0 p-1 lead m-0 border-bottom">{{ $comment->users['firstname'] }} {{ $comment->users['lastname'] }}</h6>
        <div class="p-2">
            <p>{{ $comment->comment }}</p>
        </div>
@if(isset($comments[$comment->id]))
    @include('block.comments', ['comments' => $comments, 'parent_id' => $comment->id, 'depth' => $depth + 1])
@endif
@if($depth < Config::get('site.max_nested'))
    </div>
</div>
@endif
@endforeach

然后我在配置文件夹中有一个配置文件site，内容如下

return [
    // We define the max depth for the nested comments
    // You could obviously define this value in database and be retrieving it from there
    'max_nested'    => 3,
];

我的 $comments 数组的方式是 set-up，父评论总是在 $comments[0] 而子评论在 $comments[$parent_id]

我认为这相当简单但功能有效！
