如何在Laravel 4中的控制器内部所有方法之前运行代码？

I have Content controller with REST methods (index..create..store..) and i want to run some code before any of those methods run.

what i am trying to do is to set var for my layout with some data that is relevant to all my methods within Content controller:

$this->layout->myvar = 'some-data';

I tried to do something like that:

class ContentController extends BaseController {
    function __construct() {
        $this->layout->myvar= 'some-data';
    }
..

but it doesn't seems to work. i get "Attempt to assign property of non-object" error.

Prior to Laravel 5 you could set the beforeFilter like this:

class ContentController extends BaseController {
    function __construct() {
        // this function will run before every action in the controller
        $this->beforeFilter(function()
        {
            // this will make the variable $myvar available in your view
            $this->layout->with('myvar', 'some-data');
        });
    }
}

...this has been deprecated in Laravel 5 in favour of Middleware.

try share in app/routes.php

View::share('variable_name', 'value');

ex:

View::share('name', 'Steve');

will share variable with its value across all views
