Laravel 4 - understanding View::share()

Question

From what I understand:

View::share('foo','bar');

Will make $foo available in all views.

However, is it correct to say View::share() can be used only in the __construct()?

Because from outside __construct() I can't make it to work.

Answer 1

View::share should be available anywhere within your application. A common place that it is used is in view composers, but it should be usable within a route or wherever you need it.

Answer 2

Yes, adding:

View::share('foo','bar');

in your routes.php file will make $foo (with a value of 'bar') available in all views. This is especially useful for something like Twitter Bootstrap's "active" navigation classes. For example, you could do:

View::share('navactive', '');

to make sure the navactive variable is set in all views (and thus won't throw errors) and then when you are making views (in your controller, for example), you could pass:

return View::make('one')->with('navactive', 'one');

and then in your view (preferably some bootstrappy blade template) you can do the following:

<ul class="nav">
    @if ( Auth::user() )
    <li @if ($navactive === 'one') class="active" @endif><a href="{{{ URL::to('one/') }}}">One</a></li>
    <li @if ($navactive === 'three') class="active" @endif><a href="{{{ URL::to('three/') }}}">Three</a></li>
    <li @if ($navactive === 'five') class="active" @endif><a href="{{{ URL::to('five/') }}}">Five</a></li>
    @endif
</ul>
