如何在控制器类中连接两个变量并将其传递给laravel中的类的所有视图

Question

我试图在控制器中连接两个特定于类的变量，并将其传递给所有视图，而不是在每个控制器方法中重复相同的变量。

示例代码：

    class ProductsController extends Controller
{
    private $global_path; //Comes from .env
    private $sub_folder = '/products_folder';

    public function __construct()
    {
        //Frontend Image Path - to pass into all views
        $frontend_path = $this->global_path.$this->sub_folder;

    }
}

我想将'$ frontend_path'传递给控制器​​中创建的所有刀片视图，而不是像每个方法那样重复它

return view('example_view', compact('frontend_path');

我试过View :: share ...但是无法做到。

'$ sub_folder'变量在所有控制器中没有相同的值。

有没有办法让它成为可能？

对于您的代码，我认为您可以将其更改为

class ProductsController extends Controller
{
   public $frontend_path;

   public function __construct() {
      $this->frontend_path = env('GLOBAL_PATH') . '/products_folder';
   }

   public function index()
   {
       $x = $this->frontend_path;
       return view('index', compact('x'));
   }

}

并直接使用它像$this->frontend_path或像SELF::$frontend_path下面

class ProductsController extends Controller
{
    public static $frontend_path;

    public function __construct() {
        SELF::$frontend_path = env('GLOBAL_PATH') . '/products_folder';
    }

     public function index()
     {
         $x = SELF::$frontend_path;
         return view('index', compact('x'));
     }
}

要么

class ProductsController extends Controller
{
    public static $frontend_path;

    public function __construct() {
        SELF::$frontend_path = env('GLOBAL_PATH') . '/products_folder';
        view()->share('frontend_path', SELF::$frontend_path);
    }

    public function index()
    {
        return view('index');
    }
}

在视野中

{{ $frontend_path }}
