Extend Twig with variables - php

Question

I use Twig and I have a header in each file with some variables.
How I can include the header in each file without always calling the variables ?
I've a file, in it, I extends the layout.html.twig and in this layout I extends the header.html.twig
on the header I've some variables sent by the controller. but the variables are executed only if I go to the header view...
How can I do to include the header view with twig?

Despite the fact that is really difficult to understand what exactly you're after, probably, you're looking for a way to set global variables.
Twig globals allows you to set global variables.
Set static variables:
# app/config/config.yml
twig:
# ...
globals:
variables: {}
If you need more than static variables, create your own extension:
<?php
namespace Example\CommonBundle\Twig;
use \Doctrine\ORM\EntityRepository;
class TooltipsExtension extends \Twig_Extension
{
protected $bookingsTooltip;
public function __construct(EntityRepository $bookingsTooltip)
{
$this->bookingsTooltip = $bookingsTooltip;
}
public function getGlobals()
{
return array(
'tooltips' => $this->bookingsTooltip->getTooltips(),
);
}
public function getName()
{
return 'tooltips';
}
}
Register twig extension:
# app/config/services.yml
example.tooltips_extension:
class: Example\CommonBundle\Twig\TooltipsExtension
public: false
arguments:
- #example.tooltips
tags:
- { name: twig.extension }
Access variables inside your html:
{{ dump(tooltips) }}
