Question

我需要在My Laravel应用中添加评论框。这是视图文件的评论文件夹中的评论框的刀片文件评论/ form.blade.php

 <form class="form-vertical" role="form" method="post" action="{{ route('projects.comments.create', $project->id) }}">
        <div class="form-group{{ $errors->has('comments') ? ' has-error' : '' }}">
            <textarea name="comments" class="form-control" style="width:80%;" id="comment" rows="5" cols="5"></textarea>
            @if ($errors->has('comments'))
                <span class="help-block">{{ $errors->first('comments') }}</span>
            @endif
        </div>

        <div class="form-group">
            <button type="submit" class="btn btn-info">Add Comment</button>
        </div>
        <input type="hidden" name="_token" value="{{ csrf_token() }}">
    </form>
</div>

现在我要将此文件包含在tasks文件夹中的show.blade.php文件中任务/ show.blade.php

@include('comments.form')

这是我的CommentController.php

public function postNewComment(Request $request, $id, Comment $comment)
    {
       $this->validate($request, [
            'comments'     => 'required|min:5',
        ]);

       $comment->comments       = $request->input('comments');
       $comment->project_id     = $id;
       $comment->user_id        = Auth::user()->id;
       $comment->save();

       return redirect()->back()->with('info', 'Comment posted successfully');
    }

和评论模型

 public function user()
    {
        return $this->belongsTo(User::class);
    }

但出现以下错误

Undefined variable: project (View: C:\Users\Lilan\Desktop\ratakaju\resources\views\comments\form.blade.php)

如何解决这个问题？

如何在Laravel 5.2中修复Undefined variable：project
