I have a base twig template that most pages extend from like so:
<!DOCTYPE html>
<html lang="en">
{% block header %}
{% include "blocks/header.twig" %}
{% endblock %}
<body>
{% block nav %}
{% include "blocks/nav.twig" %}
{% endblock %}
{% block body %}
{% endblock %}
{% block footer %}
{% include "blocks/header.twig" %}
{% endblock %}
</body>
</html>
I'm including a navbar that I want to conditionally change based on if a user is logged in. With just PHP templating, I would just use an autoloaded function to do this
if (loggedIn())
{
echo "Some navbar link"
}
However I can't use this function directly into twig so I assume I would have to pass the result of this function (a bool). But I'm not sure how I can pass it down multiple layers, since for example most pages will use the base template, which uses the nav block. It would be a pain to have to pass it down every single time.
