You can use: Request::url()
to obtain the current URL, here is an example:
@if(Request::url() === 'your url here')
// code
@endif
Laravel offers a method to find out, whether the URL matches a pattern or not
if (Request::is('admin/*'))
{
// code
}
Check the related documentation to obtain different request information: http://laravel.com/docs/requests#request-information
