I am new to laravel 5. In L5 there is no Illuminate/Html in the core instalation. So I put that in my composer:

    "require": {
    "laravel/framework": "~5.0",
    "illuminate/html": "5.0."
},

And 'Illuminate\Html\HtmlServiceProvider', //in composer's provider's section

And
'Form' => 'Collective\Html\FormFacade', 'Html' => 'Collective\Html\HtmlFacade', //in composer's aliases section

And than I tested in my view:

{{ Form::open(array('action' => 'UsersController@postL')) }}

{{ Form::text('name', @$name) }}

{{ Form::password('password') }}

{{ Form::submit('Send') }}

{{ Form::close() }}

plz help ..
