In Laravel, we all pass data to our view in pretty much the same way
$data = array(
'thundercats' => 'Hoooooooooooh!'
);
return View::make('myawesomeview', $data);
But is there some way to add default variables to the view without having to declare it over and over in $data? This would be very helpful for repeating variables such as usernames, PHP logic, and even CSS styles if the site demands it.
View composers are callbacks or class methods that are called when a view is created. If you have data that you want bound to a given view each time that view is created throughout your application, a view composer can organize that code into a single location. Therefore, view composers may function like "view models" or "presenters".
Defining A View Composer :
View::composer('profile', function($view)
{
$view->with('count', User::count());
});
Now each time the profile view is created, the count data will be bound to the view. In your case, it could be for id :
View::composer('myawesomeview', function($view)
{
$view->with('id', 'someId');
});
So the $id will be available to your myawesomeview view each time you create the view using :
View::make('myawesomeview', $data);
You may also attach a view composer to multiple views at once:
View::composer(array('profile','dashboard'), function($view)
{
$view->with('count', User::count());
});
If you would rather use a class based composer, which will provide the benefits of being resolved through the application IoC Container, you may do so:
View::composer('profile', 'ProfileComposer');
A view composer class should be defined like so:
class ProfileComposer {
public function compose($view)
{
$view->with('count', User::count());
}
}

'*' instead of specifying a specific view. Worked like a charm.There are couple of ways, so far I have been experiment with some.
1.Use singleton, you can put it in routes.php
App::singleton('blog_tags', function() {
return array(
'Drupal' => 'success',
'Laravel' => 'danger',
'Symfony' => 'dark',
'Wordpress' => 'info'
);
});
2.Use Settings bundle, download here. https://github.com/Phil-F/Setting. You can put this in controller or template.
Setting::set('title', 'Scheduler | Mathnasium');
3.Use View share, pretty much use it in your template
Controller: Views::share('theme_path', 'views/admin/');
Template: <link href="{{ $theme_path }}/assets/bootstrap.min.css"/>
4.My current sample setup, I wrote a construct in HomeController.
public function __construct()
{
// Define a theme namespace folder under public
View::addLocation('../public/views/admin');
View::addNamespace('admin', '../public/views/admin');
View::share('theme_path', 'views/admin/');
// Set default page title
Setting::set('title', 'Scheduler | Mathnasium');
Setting::set('description', 'daily customer scheduler.');
Setting::set('keywords', ['Reservation', 'Planner']);
Setting::set('page-title', '');
}
@enchance, as an alternative to using '*', as mentioned in your comment, perhaps a View::share would help you too. From the Laravel documentation:
You may also share a piece of data across all views:
View::share('name', 'Steve');
Excerpt is from http://laravel.com/docs/responses
Yep there absolutely is a way - see here on view composers.
You can use that to add data to a view or set of views.
