是否可以添加数据以从控制器构造函数中查看数据

Question

I have a data that I want to return in all of my controller methods and I thought that'd be cleaner to return from the controller's constructor; because currently it's just repetitive return code.

protected $data;

public function __construct() {
   $this->data = "Test";
}

public function index() {
   // Stuff

   return view('test')->with([
       'testData' => $this->data
        // other view data
   ]);
}

public function store() {
   // Stuff

   return redirect()->back()->with([
       'testData' => $this->data
        // other view data
   ]);
}

_{This is just a pseudo example.}

Answer 1

Yes, that's possible. It's done exactly in the same manner you showed.

However, I don't think that's the best way to do it. You might want to take a look into ViewComposers, which help provide a data set to a view (or multiple views) right after the controller but before the view is finally provided to the user.
