未定義的屬性：App\\Http\\Controllers\\PostController::$p

Question

我的控制器看起來像

 public function react(Request $request){
        //echo "hi";
        //return;
        //return response()->json($request);
        $this->validate($request, [
            'postid' => 'required',
            'react' => 'required'
        ]);
        $reaction = Reaction::firstOrNew([
            'post_id'=>$request->postid,
            'user_id'=> Auth::id()
        ]);
        $reaction->user_id = Auth::id();
        $reaction->type = $request->react;
        $reactType = "";
        if ($request->react === "l"){$reactType = "liked";}
        else if ($request->react === "d"){$reactType = "disliked";}
        else if ($request->react === "h"){$reactType = "loved";}
        else if ($request->react === "s"){$reactType = "Smiled";}
        else{}



        $post = Post::find($request->postid);
        $postuser = $post->user->name;

        if($post->reactions()->save($reaction)){
            $data['message'] = Auth::user()->name.' '.$reactType. ' a Post from' . $postuser;
            $data['type'] = 'reaction';
            **$this->p->trigger('user-'.$post->user_id, 'new-post', $data);**
            return response()->json([
                'success' => true,
                'message' => 'Reacted'
            ]);
        }
        else{
            return response()->json([
                'success' => false,
                'message' => 'Error'
            ]);
        }

而且我無法與 PUSHER CHANNEL 鏈接但我不斷收到錯誤消息

我究竟做錯了什么？ 非常感謝任何可能的幫助！

屬性$this->p (p) ，你還沒有設置值

$this->p = Value ;

設置后，您可以使用該信息。

$this->p->trigger('user-'.$post->user_id, 'new-post', $data);

在上面寫的代碼中， $this->p有一個空值

$this->null->trigger('user-'.$post->user_id, 'new-post', $data);

事實上，這就是你如何使用它
