【问题描述】：

如何在回复完成后阻止回复表单显示和重复其自身

@foreach($comments as $comment)
<div class="display-comment">
    <strong> $comment->user->name </strong>
    <p> $comment->comment </p>
    <a href="" id="reply"></a>
    <form method="post" action=" route('reply.add') ">
        @csrf
        <div class="form-group">
            <input type="text" name="comment" class="form-control" />
            <input type="hidden" name="post_id" value=" $post_id " />
            <input type="hidden" name="comment_id" value=" $comment->id " />
        </div>
        <div class="form-group">
            <input type="submit" class="py-0 btn btn-sm btn-outline-danger" style="font-size: 0.8em;" value="Reply" />
        </div>
    </form>
    @include('posts.comments.reply', ['comments' => $comment->replies])
</div>
@endforeach

【参考方案1】：

    @forelse($comments as $comment)
     <div class="display-comment">
       <strong> $comment->user->name </strong>
     <p> $comment->comment </p>
     @include('posts.comments.reply', ['comments' => $comment->replies])
     </div>
    @empty
     <div> No comments found</div>
    @endforelse

    <form method="post" action=" route('reply.add') ">
        @csrf
        <div class="form-group">
            <input type="text" name="comment" class="form-control" />
            <input type="hidden" name="post_id" value=" $post_id " />
            <input type="hidden" name="comment_id" value=" $comment->id " />
        </div>
        <div class="form-group">
            <input type="submit" class="py-0 btn btn-sm btn-outline-danger" style="font-size: 0.8em;" value="Reply" />
        </div>
    </form>

【讨论】：

回复表单仍在循环中自我重复

我已经编辑了我的代码，请重新考虑尝试一下

【参考方案2】：

您应该能够弄清楚。没那么难

@if (!empty($comment->replies))
    @include('posts.comments.reply', ['comments' => $comment->replies])
@empty

【讨论】：

你可以使用->isNotEmpty()，因为它是一个集合

每次回复后仍显示回复表单
