Laravel 5.7向数据库添加注释

Question

I am following tutorial for creating forum in Laravel and I am currently at posts replies so I can add them to the database.

I have this function in ForumController.php

public function postReply(CreateReplyRequest $request) {

    $post =  Post::where('slug', '=', $request['slug'])->first();

    if( $post ) {
        $reply = new Reply;

        $reply->post_id = $post->id;
        $reply->user_id = Auth::user()->id;
        $reply->text = $request['text'];

        $reply->save();

        return redirect()->back();
    }
    return redirect('/');
}

It is only returning me back to homepage (/) and not adding any reply to database. I do not know where can be error. Thanks for help.

Try this:

 public function postReply(CreateReplyRequest $request) {

    $post =  Post::where('slug', $request['slug'])->first();

    if( $post != null) {
        $reply = new Reply;

        $reply->post_id = $post->id;
        $reply->user_id = Auth::user()->id;
        $reply->text = $request['text'];

        $reply->save();

        return redirect()->back();
    }
}

Thanks for answers. I had to install Form package from Laravel Collective via Composer. I had to pass the slug via {!! Form::hidden('slug', $post->slug) !!} {!! Form::hidden('slug', $post->slug) !!} . Thanks for help.
