laravel4 passing variable from constructor to view

Question

I got an $inbox_unread variable store in the master page. I do not want each of function assign the $inbox_unread, how do I make it in the constructor?

I had tried

public function __construct()
{
    $this->beforeFilter('csrf', array('on'=>'post'));
    $this->layout->inbox_unread = '123';
}

However, it does not work. All my page have to get this variable except login page. How do I achieve this with clean and good practise?

Thanks!

You can try with a View Composer. http://laravel.com/docs/responses#view-composers — user2094178, Apr 05 '14 at 02:58
Can you show me solution how to implement it in route.php, controller, and view? — Shiro, Apr 05 '14 at 03:56

You can use the following code at App::before located in ./app/filters.php:

Config::set('myvar', array('key' => 'value'));

Now anywhere in your app you can retrieve it as Config::get('myvar.key').

If you were to do the following at the same location:

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

Then you'll have $myvar available in all your views. You can also do:

View::share('myvar', array('key' => 'value'));

And retrieve as $myvar["key"].

Sorry for didn't make the things clear, my inbox_unread's value is get from a Model. Inbox::unread();, from your answer, it more to preset value for me. – Shiro Apr 05 '14 at 09:20
You can use your model also in `App:before`. Please check this link, http://stackoverflow.com/questions/19952572/global-variable-in-laravel-4 – user2094178 Apr 05 '14 at 16:47
