Question

I define variable in controller and pass it to template but it’s not visible in extend block. The important controller code is:

        $response['html'] = $this->renderView(
            'AldenXyzBundle:Profile:edit_ajax.html.twig', array(
                'isXmlHttpRequest' => $request->isXmlHttpRequest(),
            )
        );

and Twig template

{% extends isXmlHttpRequest ? '::base-ajax.html.twig' : '::base.html.twig' %}

{% block content %}
...
{% endblock %}

and I have exception Variable "isXmlHttpRequest" does not exist in ... while the template

{% extends '::base-ajax.html.twig' %}

{% block content %}
{{ dump(isXmlHttpRequest) }}
...
{% endblock %}

works well and display correct $isXmlHttpRequest value.

I also tried directly in template:

{% extends app.request.isXmlHttpRequest ? '::base-ajax.html.twig' : '::base.html.twig' %}

but I got an exception saying app is undefined.

I’m using symfony v2.0.15 and twig v1.8.2

This will work:

{% set layout = app.request.isXmlHttpRequest ? '::base-ajax.html.twig' : '::base.html.twig' %}
{% extends layout %}
